00:00:00So, it's pouring outside when you get on a plane.
00:00:03If you were in a car, you'd simply switch on the windshield wipers and the headlights
00:00:07after turning the key in the ignition.
00:00:10Do pilots do that?
00:00:12Airplanes spark so many questions, and it's time for some answers!
00:00:16Do planes have windshield wipers?
00:00:18Yes, commercial planes do, but they're only used during taxiing, take-off, and landing.
00:00:24Once a plane reaches its cruising altitude, pilots turn them off.
00:00:28The plane's speed is fast enough to clear the windshields from rain.
00:00:32Wipers might be absent on single-engine airplanes because the propeller airstream blows strong
00:00:37enough to keep the water away.
00:00:40What happens when a plane loses one engine in flight?
00:00:44Actually it goes, hey, has anybody seen my engine?
00:00:46It was just here a second ago!
00:00:48No, nothing special, the plane actually just keeps flying.
00:00:53There are certificates for planes flying over oceans or long distances that state how long
00:00:58they can do it.
00:00:59For example, the Boeing 787 can fly for more than 5 hours without the second engine.
00:01:05It's enough for pilots to plan a safe landing.
00:01:09Why is it so cold on a plane?
00:01:11The temperature on board averages 74°F, about the same as in most office buildings.
00:01:18But you feel so cold because your body doesn't move much, producing less heat to warm itself.
00:01:23The crew doesn't turn the heat up because hot air can cause some passengers to faint
00:01:28during the flight.
00:01:29Do airplanes have horns?
00:01:31Yeah, and some of them have a whole trumpet section.
00:01:35Actually yes, they do have horns, but pilots don't use it to scare away birds or get
00:01:40other aircraft's attention in the sky.
00:01:42Hey, move over, buddy!
00:01:45Actually you can hear that high-pitched chime only on the ground when the plane isn't
00:01:50Like when an engineer checks something in the cockpit and wants to get the attention
00:01:54of a ground crew member.
00:01:57Why do planes leave white trails in the sky?
00:02:00It happens when the engine burns fuel.
00:02:02It ejects water and carbon dioxide that gets mixed with the atmosphere.
00:02:07And since the air is cold at high altitude, and this exhaust is hot, the water condenses
00:02:13and may freeze, creating those white tails.
00:02:17Do airplanes have brakes?
00:02:19Yes, there are multiple disc brakes made of carbon steel material, similar to the ones
00:02:24in your car.
00:02:25But using them only isn't enough to stop the plane when it touches the ground.
00:02:29The braking system also includes different surfaces that slide out of the wings and disrupt
00:02:35the airflow.
00:02:36Can a plane door open mid-flight?
00:02:39The cabin pressure is the force that won't let that happen.
00:02:43If someone tried to do it, they would have to overcome more than 24,000 pounds of pressure,
00:02:48the weight of a ship anchor.
00:02:50Plus there are lock bolts deep inside the aircraft's structure that hold the door
00:02:54in place.
00:02:56What happens when lightning hits a plane?
00:02:59Now statistics say this happens to every commercial plane about once a year.
00:03:03But the aircraft's metal parts and lightning protection systems prevent electrical buildup.
00:03:09So in most cases, this leaves a plane with only a scorch mark on its surface.
00:03:15Why don't the seats and windows always line up?
00:03:19Good question!
00:03:20All commercial planes are designed with seats and windows perfectly aligned.
00:03:24But when an airline buys a jet, it often chooses to add extra seats.
00:03:29More seats mean more passengers and more tickets sold.
00:03:33And less of a view and less legroom for you.
00:03:36See how that works?
00:03:38Why do flight attendants touch the overhead compartment?
00:03:42You'd think that they're checking to see if it's closed tightly.
00:03:45But nope.
00:03:46They use a scalloped handrail hidden at the bottom of the overhead compartment for a steadier
00:03:51walk along the aisle.
00:03:54What are those white spiral marks on engines for?
00:03:57Well, since the ground staff wear hearing protection, they can't rely on their ears
00:04:02to decide if it's safe to approach the plane.
00:04:05Seeing that moving swirl on jet engines prompts them to stay away from the area.
00:04:11Why are there holes in airplane windows?
00:04:14Those windows actually have three panes of plexiglass.
00:04:17The tiny hole is in the middle one.
00:04:19It helps regulate the huge pressure difference inside and outside the cabin, so the outer
00:04:24pane can handle the load.
00:04:26If the outer pane happened to break, the middle one, even with a hole in it, would still be
00:04:31enough to keep the window intact.
00:04:33That hole also keeps the windows from fogging up.
00:04:37Why are there hooks on the wings?
00:04:39If there is an emergency landing on water, passengers have to step on the slippery wings
00:04:44to use some emergency exits.
00:04:46That's why crew members secure one end of a rope to the doorframe and the other to the
00:04:51wing through the hook.
00:04:53Another rope is secured in the second hole, safely leading passengers along the wing to
00:04:58the inflatable slide.
00:05:01Why do the wings have different colored lights?
00:05:03It's for Christmas.
00:05:05Nah, that red light on the left wing tip, the green one on the right, and the white
00:05:09one on the tail make up the plane's navigational lights.
00:05:13They let other pilots know the plane's position and the direction it's moving in, toward
00:05:18them or away.
00:05:21Do planes have ignition keys?
00:05:23Well, since ignition keys are usually a security measure, most commercial planes don't need
00:05:28them.
00:05:29They're locked in hangars under 24-7 surveillance.
00:05:32To start the engine, a pilot just pushes buttons and turns switches.
00:05:37But smaller private planes, like a Cessna, have ignition keys to start the engine and
00:05:42even locks on the doors.
00:05:44Why are there triangles above the windows?
00:05:48These black and sometimes red stickers let the crew know which window is best to look
00:05:52out when they want to check the moving parts of the wing.
00:05:56If you get motion sickness during the flight, try to choose a seat between the triangles
00:06:01for a more comfortable trip.
00:06:03How can you get extra space on a plane?
00:06:07If you're lucky enough to get an aisle seat, there's a magic button near the hinge under
00:06:11the armrest closest to the aisle.
00:06:14Press it, and the armrest will swing up to the back of your seat.
00:06:19Why are most planes white?
00:06:22This color reflects the sun better than any other, so it helps keep a plane cool.
00:06:27It's also much easier to spot any cracks, dents, leaks, and other faults on the white
00:06:32surface.
00:06:33And paint makes a plane 1,200 pounds heavier, causing it to burn more fuel.
00:06:38Airlines save money by not painting them.
00:06:42Why don't airplanes have parachutes for passengers?
00:06:45Like paint, parachutes would also add extra weight – around 8,000 pounds.
00:06:51Plus, skydivers must go through at least 4 hours of training to learn how to handle a
00:06:56parachute.
00:06:57Lastly, jumping out of a plane at 35,000 feet in the air is simply not safe, because
00:07:02temperatures at that altitude are colder than the Arctic – minus 65 degrees.
00:07:09Why can't planes fly when it's hot?
00:07:12Well the molecules in hot air are much more spread out.
00:07:15To lift a plane, you need dense air.
00:07:18That's why it gets harder for a plane to take off as the temperature increases.
00:07:22Besides, scorching weather can overheat the internal machinery or even melt some of its
00:07:28parts.
00:07:29So, if it gets 104 degrees Fahrenheit outside, your flight might be delayed.
00:07:35Why do planes have round windows?
00:07:38The very first commercial planes had square ones.
00:07:41But after some time, they started flying at a higher altitude that demanded the cabin
00:07:45be pressurized.
00:07:47Depressurization and depressurization deformed and even broke windows with corners.
00:07:53They were replaced with round ones since they withstand the pressure much better.
00:07:59How do the oxygen masks work?
00:08:01Very well, actually.
00:08:03If the cabin is depressurized at cruising altitude, it loses oxygen.
00:08:08The masks provide that, but only for 15 minutes.
00:08:11It's okay, though – that's long enough for the pilot to descend lower than 10,000
00:08:16feet where the air has more oxygen and people can breathe normally.
00:08:21What causes turbulence?
00:08:23Your trip gets bumpy because of three main reasons – storms, mountains, and jet streams.
00:08:29Just like an ocean, air creates waves when it meets a mountain.
00:08:33And sometimes it has nowhere to go but up in strong currents affecting a plane.
00:08:38Jet streams are bands of swift winds that appear when warm air masses collide with cold
00:08:44ones.
00:08:45Storm clouds push air away, creating unpredictable waves.
00:08:49Why do planes sometimes dump fuel?
00:08:52If there's an emergency landing, pilots must quickly get rid of excess weight, since
00:08:57they didn't burn it, and get to the destination runway as light as they should be.
00:09:01The lighter the plane, the softer it'll touch the ground, so no blown tires or fire.
00:09:09Why are the doors on the left side?
00:09:12The captain usually sits on that side, so aligning the plane with the terminal jet bridge
00:09:16is easier.
00:09:18They fuel the aircraft and load baggage on the right side.
00:09:22If passengers are coming in on the left, it doesn't disturb those crews.
00:09:26Why do they dim the lights during take-off and landing?
00:09:30It takes your eyes up to 30 minutes to fully adjust to a dark setting.
00:09:34Dimming the lights at night or dusk prepares them in case passengers need to make an emergency
00:09:40exit.
00:09:41They fade the lights during the day to save some engine power.
00:09:45Why are most plane seats blue?
00:09:48This color is psychologically associated with safety and reliability, so flight-weary passengers
00:09:54feel less anxious.
00:09:56Besides, stains and dirt are less visible on blue seats.
00:10:00Now we know!
00:10:01There's a tricky anti-rodent disc to make sure no rat is aboard.
00:10:06Rodents usually get on a boat via mooring chains, so this disc fits onto them.
00:10:11And no rodent can go on a voyage.
00:10:14Jewelry is often sold in small pouches.
00:10:17They actually have a hidden purpose.
00:10:19They help prevent tarnish.
00:10:21Most retailers assure that the ring or whatsoever was sold is safe and secure.
00:10:26In most supermarkets, oranges usually come in mesh bags.
00:10:30Well, those bags don't really have any hidden purpose, but you can turn it into a great
00:10:34scrubbing tool.
00:10:36Tie it up and see how it works next time you have an extra greasy frying pan.
00:10:41You don't need to scoop the jam out of a double yogurt container section.
00:10:45This type of plastic is quite flexible, so you just need to fold it in half and pour
00:10:49the jam directly into the yogurt section.
00:10:53The hidden function of a cup plunger is actually that it was meant to be used for sinks.
00:10:57Yeah, it works for toilets too, but you can keep an extra one to unclog the sink in case
00:11:02you need it.
00:11:04An extra hole at the upper part of the sink has multiple hidden functions.
00:11:08First, in case someone forgets to close the tap, the water won't overflow and the bathroom
00:11:13won't get flooded.
00:11:14Second, thanks to that hole, the water drains faster as it gives an escape for the air helping
00:11:20the water flow down.
00:11:23Most metallic zippers have a hidden lock inside them to save them from awkward situations
00:11:27such as an undone fly.
00:11:29Don't leave the zipper handle in an upward position.
00:11:32When you pull it downwards, it automatically locks.
00:11:35It's all thanks to those tiny grooves hidden underneath the handle.
00:11:39Bath foam isn't only for fun or a nice smell.
00:11:42It also helps regulate the temperature.
00:11:44The bubbles keep the water hot, so you can enjoy a bath a bit longer.
00:11:48Anyway, it works for acrylic bathtubs only.
00:11:51Those made of metal lose heat really fast either way.
00:11:55Escalator brushes aren't for keeping your shoes clean and polished.
00:11:58It might be tough to apply wax right on that brush while the escalator's moving.
00:12:03It's for our safety.
00:12:04Brushes won't let you come close to the edge, so a long coat or boot cut jeans won't end
00:12:09up in between the steps.
00:12:11Originally, golf balls were smooth.
00:12:14They have a dimpled surface now because players noticed that overused balls with damages flew
00:12:19better than brand new ones.
00:12:21At some point, manufacturers started producing balls with dimples.
00:12:26If you take a box of aluminum foil, you'll see tabs you can press on the side.
00:12:31They keep the foil straight and prevent it from rolling.
00:12:34It's also easier to tear off some amount of foil thanks to those tabs.
00:12:38Jerry cans have three handles for a reason.
00:12:41It's a smart designer move, so when you carry it alone, you use only the central handle
00:12:46to distribute the weight evenly.
00:12:48But your friend wants to help you out.
00:12:49Each of you grabs the side handle.
00:12:52Two flat prongs you can see on standard plugs used in North and Central America make sense.
00:12:57But how about those holes near the tips?
00:13:00Thanks to them, the outlet firmly grips the plug so that it won't loosen or fall out of
00:13:04the socket.
00:13:05It's sometimes irritating when you haven't used the entire stick of deodorant.
00:13:10There's a little bit more left, but it's hard to reach it.
00:13:13Okay, the trick is easy.
00:13:14Unscrew the bottom, take a pencil, and force it underneath that moving platform.
00:13:19That way, you'll push what's left of the deodorant out.
00:13:23There's a number put on the side of many cosmetic products.
00:13:27It isn't picked randomly.
00:13:28It tells you how long your product will last after you've opened it.
00:13:32This is why it has an open jar for a graphic symbol.
00:13:35A lint roller is good at removing those tiny fibers, but you can also use it to clean other
00:13:39stuff.
00:13:40For example, when you want to remove the dirt from the utensil tray in your dishwasher,
00:13:45simply take your sticky lint roller and put it into each compartment, and all the crumbs,
00:13:49dirt, and leftovers are all gone.
00:13:52Kings depicted on playing cards are real historical characters.
00:13:56Spades, King David.
00:13:58Clubs, Alexander the Great.
00:14:00Hearts, Charles the Great.
00:14:02Diamonds, Julius Caesar.
00:14:05Rings used to be more than a stylish accessory.
00:14:08The nobility used rings as a seal.
00:14:11Archers wore rings to protect their fingers from bowstring injuries, while needlewomen
00:14:15from needle pricks.
00:14:18Detachable headrests in cars are all about safety.
00:14:21If you pull it out of a seat, you'll see two pretty sturdy bars.
00:14:24If you ever get locked or trapped in a car, you can get out of there smashing the window
00:14:28with these bars.
00:14:31A little arrow next to the refueling indicator on the car's dashboard indicates which side
00:14:35of the vehicle has fuel tank openings.
00:14:38It's useful when you need to refuel a rented car.
00:14:41You are probably using shampoo wrong all the time.
00:14:45Well, the main thing you should know is that you don't apply it directly on your hair.
00:14:48You gotta apply it onto the roots only.
00:14:51The foam that you make is enough to clean your hair.
00:14:54A button on the reverse side of a shirt collar is needed to hold a tie in place.
00:14:59Anyway, this button was designed for slim ties that are not that popular today, so this
00:15:04button is only an element of design.
00:15:07A cotton pads pack has those strings on it to hang it on some hook or holder.
00:15:11There's no need to untighten and tighten the pack again.
00:15:14Look at the bottom.
00:15:15It has a perforated line.
00:15:17Tear along it and just pull out a cotton pad from a hanging pack.
00:15:22It's a myth that the red side of the eraser is for pencil and the blue one is for ink.
00:15:27The blue gets rid of mistakes on thicker types of paper only.
00:15:30It works both for pencil and even ink, but make sure the paper is really thick.
00:15:35But that blue little thing can do so much more.
00:15:38It can polish your jewelry, clean your electronics.
00:15:40For example, the screen of your cell phone.
00:15:43You know those irritating sticker residues that won't peel off?
00:15:46Eraser helps there too.
00:15:48Same as with cleaning scuffed up suede or dirt you have on your walls.
00:15:52There's no need to tear one of its edges on stick sachets.
00:15:55The right way is to tear them down the middle.
00:15:57You say it's not a big difference, but at least there's less mess with those torn paper
00:16:01bits.
00:16:02A small V patch at the bottom of the collar helps put on the sweater without losing any
00:16:06shape over time because it's made of a double layer of webbing material, just like waistbands
00:16:12and cuffs.
00:16:13To avoid spilling juice right onto your t-shirt, try pouring it from the other side of the
00:16:18carton.
00:16:19This way, it sloshes less and it's easier to control.
00:16:23To enjoy fresh and soft peanut butter, store it upside down.
00:16:27This way, the oils won't stay on the bottom all the time and distribute evenly in the
00:16:31jar.
00:16:32Yeah, you've heard before that a drawer beneath your oven is there for keeping the food warm
00:16:36if the guests are running late.
00:16:38Hey, you can also slow cook on lower temperatures in that drawer.
00:16:42Automatic lip liners and eye pencils sometimes have a sharpener installed in the package.
00:16:48The lid on the back part of the pencil doesn't only reveal the color.
00:16:52You can pull it out and sharpen up the product.
00:16:55Grocery cart loops help organize all the stuff in your cart better so you can enjoy your
00:16:59supermarket trip.
00:17:01You don't want to put your brand new fancy white jacket in a cart next to carrots and
00:17:05onions, huh?
00:17:06Fruit stickers know everything about your apple's past.
00:17:10A five-digit number where the first number is nine is a good sign.
00:17:14It's an organic product.
00:17:16A four-digit number starting with a three or four means it was conventionally farmed.
00:17:21If the number starts with an eight and there are five digits, it's best to leave it on
00:17:25the shelf.
00:17:26Metal buttons on jeans, also known as rivets, help make the pockets more durable when miners
00:17:31would fill them with heavy tools.
00:17:34They're still helpful today.
00:17:35Even if you don't store anything heavy in your pockets, rivets strengthen the seams
00:17:39and make your jeans last longer.
00:17:42All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
00:17:47The lid has the same shape as the candy.
00:17:49Turn the container upside down, gently shake it, and slowly open it.
00:17:53You'll notice only one candy stuck between those lid grooves.
00:17:57So if you just open the container and shake it until five or even more candies fall into
00:18:01your mouth, it means you've been eating Tic Tacs wrong all this time!
00:18:07Above each car door, you'll usually find a handle.
00:18:10I call it the Oh No handle.
00:18:13It's there to give you something to hold on to when your grandma decides to go full NASCAR.
00:18:18These handles are actually especially useful, all jokes aside.
00:18:22Me, jokes aside?
00:18:24A lot of people need a little extra help getting in and out of the car.
00:18:29As for why the driver's door usually doesn't have one, there are a couple of reasons.
00:18:33For one, the steering wheel can function as a makeshift grab handle.
00:18:38Drivers might also be inclined to grab the handle while driving.
00:18:42Not safe.
00:18:44Modern car keys have a nice trick up their sleeve, if they had sleeves.
00:18:48They can control your windows.
00:18:50Try holding the unlock button on your car keys for a few seconds.
00:18:54There's a chance that after 5 seconds, your car windows will magically open.
00:18:59If you hold the lock button again, your windows should close.
00:19:03Only a few special people actually use this cool trick.
00:19:06Check out your owner's manual.
00:19:08Your car might be one of the lucky ones.
00:19:11If your Internet goes down and you really need that gaming fix, Google has you covered.
00:19:17You click on your favorite shortcut and disaster.
00:19:20A dreaded message appears, unable to connect to the Internet.
00:19:24But wait, what's that little pixelated dinosaur next to it?
00:19:29Instead of panicking, press that space bar.
00:19:32This little game has become a huge hit, and it's a lot more addictive than it looks.
00:19:36A dinosaur jumping over a cactus?
00:19:39Genius!
00:19:41During the colder months, putting on a beanie can mean the difference between staying home
00:19:45and going outside.
00:19:47But you can thank French sailors for the pom-pom on top.
00:19:51This was to stop them from banging their heads on those pesky beams down below.
00:19:57Fast forward a bunch of decades, now everyone's wearing them.
00:20:02Next time you're on a flight, look above each window.
00:20:04You'll notice some little triangles sitting there.
00:20:07They're there to show the flight crew the best spots to view the plane's flaps through
00:20:11the window.
00:20:13If you're worried about a little air sickness ruining your flight, try to choose a seat
00:20:17that's located between these triangles.
00:20:20Sitting between the wings puts you in the direct center of the plane and offers the
00:20:24smoothest possible ride.
00:20:28Sitting in a long traffic light usually makes me hungry, bored, and a little curious.
00:20:33Have you ever thought about those black dots and that black line all along the edges of
00:20:37your windshield?
00:20:39It looks cool enough, but come on, it's gotta have a hidden use, right?
00:20:43Well, the black line is called a frit, and it's there to help your windshield from popping
00:20:48out of the car.
00:20:50Pretty important, I'd say!
00:20:52Microwavable instant rice loves to fall over in the microwave, if you're me, that is.
00:20:58And like me, you've probably struggled with keeping the package upright.
00:21:02As it turns out, the flaps that fold out from the bottom create a nice sturdy base.
00:21:08Push them out and give it a try!
00:21:10Hey, why didn't I learn this in school?
00:21:13Has that half-finished 2-liter bottle of soda left over from pizza night gone flat?
00:21:19Rather than pouring it down the drain, add it to your compost heap.
00:21:23The sugar feeds good microorganisms and increases the acidity of the pile, helping organic material
00:21:29break down faster.
00:21:32Any pair of scissors will go blunt sooner or later, but don't let that stop you.
00:21:37There's a product in your kitchen that can help bring them back to life fast.
00:21:42Aluminum foil isn't just for leftover lasagna.
00:21:45Fold a sheet of it into quarters and start cutting.
00:21:49Cutting through the foil will sharpen those scissors right up, but not if they're too
00:21:53blunt.
00:21:54Rescue them while there's still time!
00:21:56Those little escalator brushes aren't there to clean your shoes, even though they can
00:22:00do a rather good job.
00:22:02These bristles are actually a serious safety feature.
00:22:05Without them, clothes, shoelaces, and bags can get caught in them when they're too close
00:22:10to the sides.
00:22:12The little brushes are also there to tickle you, to remind you to look down and take care.
00:22:17Hey, I always thought it was a bug rubbing up against me!
00:22:22Half-belts.
00:22:23Seriously, what's up with those things?
00:22:25Some military jackets used to double as blankets, and the half-belt helped keep the extra material
00:22:31from getting in the soldier's way.
00:22:33Nowadays, they're mostly used as a fashion accessory.
00:22:37Accidentally stapling the wrong pages together is like the worst thing ever!
00:22:41Well, there are worse things, but it's certainly annoying.
00:22:45Especially if the staple takes out a huge piece of your document with it when you try
00:22:48to pry it off.
00:22:50There's actually a simple way to make sure that the stapler pins are less tight and easier
00:22:55to pull out.
00:22:56Take a close look at that metal plate at the front of your stapler, known as the anvil.
00:23:02Turn the stapler upside down and adjust the settings.
00:23:05You're basically changing the stapler setting to temporary.
00:23:09No more tears, no more tears.
00:23:11Mention my name and you'll get a good seat.
00:23:14Toilet seat covers have been used wrong for way too long.
00:23:17I see you ripping off that flap that looks like a tongue.
00:23:21Now you're doing it all wrong.
00:23:23Instead of tearing it off, let the flap sit in the bowl after you put it down the cover.
00:23:28When you flush, the suction will pull on the flap and take it away.
00:23:32Aren't you glad you know that now?
00:23:35That dark square or rectangle at the end of your toothpaste tube?
00:23:39What does that mean?
00:23:40Is it color-coded to show what ingredients are in there?
00:23:43Or does it show whether the toothpaste is synthetic or natural?
00:23:47Well, sorry, but the truth isn't that exciting.
00:23:50The markings are there for the assembly machines.
00:23:52They help the machines know where to cut and fold each tube.
00:23:57We've all driven home from the supermarket, taken a right turn a little too hard, and
00:24:01– crash!
00:24:02Sounds like the groceries volcano just erupted in the trunk.
00:24:06Look closely in the trunk.
00:24:08You might see some little hooks in there.
00:24:10You can hang your bags on them.
00:24:13Yeah, some cars have them behind the front seats instead.
00:24:17You can use them to hang clothes or even your take-out bag.
00:24:21You may have noticed that members of the flight crew like to touch the overhead compartments
00:24:26while they're walking down the aisle.
00:24:28They don't have a weird desire to touch everything.
00:24:31There are actually handles along the edges to give them a better grip while walking.
00:24:36Go ahead and use them the next time you feel like a mid-air stroll.
00:24:40It's definitely better than grabbing onto everyone's headrests.
00:24:43Don't you hate that?
00:24:45A shiny brass doorknob adds just the right amount of fancy to your front door.
00:24:50But that's not all it does.
00:24:52Brass, like anything with copper alloy in it, has antimicrobial properties that many
00:24:57harmful germs and bacteria just can't stand.
00:25:00In high-traffic areas, these brass knobs and handles are the perfect way to get rid of
00:25:05those nasty germs without having to use harsh chemicals all the time.
00:25:10The only downside is that brass is a lot more expensive than other metals.
00:25:14That might be why it's hardly used for this anymore.
00:25:18Does your toothbrush have a pattern of blue bristles weaved in with the white ones?
00:25:23It makes the toothbrush look a lot more stylish, but it's not just about looking good.
00:25:28Those bristles actually have a practical purpose.
00:25:31The blue dye is designed to wear off around the same time as when you should replace your
00:25:36toothbrush.
00:25:37You should be switching out your toothbrush every 3-4 months anyway, but those blue bristles
00:25:42are there to give you a gentle nudge just in case you forget.
00:25:47You walk over them every day and never think about it twice, but is there a reason maintenance
00:25:52hole covers are always round?
00:25:55In past civilizations, like Ancient Rome, these covers used to be square-shaped slabs
00:26:00of stone.
00:26:01But all those edges and gaps led to plenty of stubbed toes and accidents for unsuspecting
00:26:06Romans.
00:26:07A round cover eliminated the problem, plus it meant you could only open it with a specialized
00:26:13tool.
00:26:14Probably a good idea.
00:26:16The thermos was invented by a Scottish scientist, but not for keeping his coffee warm.
00:26:21He just wanted to keep some chemicals at a stable temperature.
00:26:25He placed a small bottle inside of a larger one and then sucked all the air out from between
00:26:30the two bottles.
00:26:31This same technique is used to make the modern thermos.
00:26:35You can find a pincushion in just about every household, and strangely, it's always in
00:26:40the shape of a tomato.
00:26:42Ever wondered about that little strawberry dangling from the top?
00:26:46I'm no biologist, but I'm quite sure that strawberries don't grow on tomatoes.
00:26:51That little thing's for the needle you're currently using, so you don't lose it in
00:26:55that big pile you have.
00:26:58Sticky odorants go to waste when the casing starts rubbing against your skin, but there's
00:27:02still plenty left in there.
00:27:03Here's an easy trick to get it out.
00:27:06Unscrew the bottom and push it up from underneath.
00:27:09That'll give you a few more days at least.
00:27:12Some people still drive off from the gas station with the hose shoved in their gas
00:27:16tank.
00:27:17Oh boy.
00:27:18Luckily, gas companies figured out a solution.
00:27:21If you happen to drive off with the hose still in there, there's a magnetic connector that
00:27:25disengages when pulled.
00:27:28That way, you don't take the pump with you.
00:27:30Now that would be embarrassing.
00:27:32Opening jars can be tough, even for the strongest person.
00:27:36I need a pickle, stat.
00:27:39Luckily, there's a solution.
00:27:41Pop on some rubber gloves.
00:27:43These gloves aren't simply great for cleaning, they'll give you the extra grip you need
00:27:47to open even the toughest of containers.
00:27:50Now your life is just a little bit better.
00:27:53You're welcome.
00:27:56Grocery carts have loops for a reason.
00:27:58You don't want to put your jacket in your cart next to a bunch of potatoes and onions,
00:28:03do you?
00:28:04Hang it on the loop instead – it's there to help you organize your cart better.
00:28:09Carts also have a cool section at the bottom.
00:28:11Whenever your cart's full, just lift it up and attach a shopping basket for extra
00:28:16purchases.
00:28:17Lift up the whole metal thing, sit your basket on the horizontal bar above the wheels, and
00:28:22secure it with those handy hooks.
00:28:25If you've got some pesky parsley stuck in your teeth, try this tip.
00:28:30It can be hard to get it all out with loose floss.
00:28:33You need more tension.
00:28:34Just tie it in a knot.
00:28:37Blue Stripes may seem a bit weird – it's just a marketing trick.
00:28:41Back in the 70s, a leading toothpaste brand added a blue stripe to show that their toothpaste
00:28:47had double action.
00:28:49Solid white toothpaste worked just as well.
00:28:52But those blue bristles on your toothbrush actually make sense.
00:28:56They gradually lose their color over time.
00:28:59When the blue's faded, it's time to change your toothbrush.
00:29:04Ever notice that tiny hole on the bottom of a padlock?
00:29:07Its hidden purpose is to drain water out, to keep it from rusting.
00:29:11It's also the place to lubricate a padlock.
00:29:14A drop of oil in there will make it open and close way easier.
00:29:19Those ridges on the edge of dimes aren't just for show.
00:29:23People used to shave off the edges, then melt the edges down into new coins.
00:29:28But thanks to the new design, it's easy to tell if someone's been shaving the edges
00:29:33off.
00:29:34If you still struggle with peeling an orange, here's another way of opening it.
00:29:39First, cut off the top and bottom.
00:29:42Make a slit on the side and pull it open.
00:29:45That knobbly bit sticking out of the cap of your favorite cream is there for a reason.
00:29:50These tubes are usually sealed with foil.
00:29:52So unless you love breaking your nails trying to open them, just flip the cap over and pull
00:29:58and push.
00:29:59The tiny rubber disc under every bottle cap isn't just for seeing if you want a lifetime
00:30:05supply of soda.
00:30:06It's what keeps your drink all nice and bubbly.
00:30:09The lid keeps the liquid inside.
00:30:12The rubber disc keeps the gas inside.
00:30:15Until you drink it.
00:30:17If you use the blue side of your eraser to erase pen, your notebooks are probably all
00:30:22full of holes.
00:30:23The blue side's there for when you need to erase something on much thicker paper.
00:30:28It works on pencil and even ink, as long as the paper's thick enough.
00:30:33Your bobby pins might not stay in place if the grooves aren't facing the right way.
00:30:38They should always be on the bottom, close to your head.
00:30:42Still coming loose?
00:30:43Put a squeeze of hairspray right onto the bobby pin before you put it in your hair.
00:30:49Many glass bottles usually have some sort of indent at the bottom.
00:30:54It's handy if you want to be fancy.
00:30:56Put your thumb in the indent and pour away.
00:31:00The technical name for this little dude is a punt.
00:31:03Those sugar sticks at your local coffee stand are ready to be opened in a new and easier
00:31:09way.
00:31:10Look how happy they are!
00:31:11Try splitting it right down the middle.
00:31:13No more sugar on your fingers.
00:31:15No more tiny little paper bit.
00:31:18Even your coffee's happier.
00:31:20Your cotton rounds pack has those strings on it, so you can hang it on a handy hook
00:31:24in the bathroom.
00:31:26But there's no need to loosen and tighten back up again every time.
00:31:31Check out the bottom of the pack – it has a perforated line.
00:31:35Tear it open carefully, and you're good to go.
00:31:38Doorknobs are usually made of brass, bronze, or some other copper alloy.
00:31:43Why?
00:31:44They're antibacterial, so they stop microbes from spreading.
00:31:48Just a couple of hours, and the pesky microbes are gone.
00:31:52But don't forget to wash your hands anyway!
00:31:55Bottles have long necks for a reason.
00:31:58Hold the neck, not the bottle, if you want to enjoy a cold drink.
00:32:02Two zips too much?
00:32:04Maybe.
00:32:05But they come in handy as a clever anti-theft device.
00:32:09Just lock them together.
00:32:10Now no one can open your backpack.
00:32:13Don't have a lock on you?
00:32:14You can also tie them together with some string, or even just a paperclip – anything
00:32:19to slow those pickpockets down.
00:32:23That tiny little button on the back of a shirt collar is used to hold your tie in place.
00:32:28You don't want your tie trying to escape back there.
00:32:32Shoe manufacturers care about their customers, so most running shoes now have a special anti-blister
00:32:38system pre-installed.
00:32:41Sounds intense, but it's basically just that extra hole on top of your sneakers.
00:32:46Make a loop with the extra hole, inserting the lace backwards.
00:32:50Cross your laces and put them through the loops.
00:32:53Now pull the laces down to lock your foot in place.
00:32:57Now run!
00:32:59You'll find silica gel packets when you buy bags, shoes, even some snacks.
00:33:04Don't throw them away.
00:33:06They soak up excess moisture, so any time your shoes are a bit damp, chuck a few gel
00:33:13packets in there overnight.
00:33:15You might've been using your shampoo wrong this whole time.
00:33:18Really.
00:33:19Here's the gist.
00:33:20Don't apply it to your hair.
00:33:22Just apply it to the roots.
00:33:24The foam you create will trickle down on your hair anyway.
00:33:28Notebook margins aren't for taking extra notes or practicing emojis.
00:33:33They were invented to protect people's work.
00:33:36People used to live with a lot of hungry rats around.
00:33:39The rats would nibble at the paper, eating people's work.
00:33:43They put the margin lines there to let people know to start their writing further from the
00:33:47edge, so it's not lost to a hungry rodent.
00:33:51Solo cups are the key element for any barbecue party.
00:33:55But these red cups are even cooler than you thought.
00:33:58You can use them to measure liquids.
00:34:01The bottom line equals 1 oz., the second line equals 5 oz., and the third line equals
00:34:0712 oz.
00:34:09If you like milk on your tea, try this tip out next time.
00:34:12Pour it from the other side of the carton.
00:34:15It sloshes around less, and it's easier to control.
00:34:19Car headrests are all about comfort, and detachable headrests are all about safety.
00:34:25If you pull the headrest out, you'll see two sturdy metal bars.
00:34:30If you ever get locked or trapped in a car, you can use the bars to smash the window and
00:34:35get out.
00:34:37Women's shirts have their buttons on the left, even though about 85% of people are
00:34:42right-handed.
00:34:43It would make way more sense to have them on the right.
00:34:46The thing is, back in the day, wealthy women had maids to help them dress.
00:34:52So for them, the buttons on the left made things much easier, don't you know?
00:34:59The tab on your rear-view mirror does have a real function, people.
00:35:03It holds your air freshener, your huge fuzzy dyes, maybe a big smiley emoji, but it's
00:35:09actually a switch between day and night mode for your mirror.
00:35:13When it's dark out, the night mode blocks the glare from the car behind you.
00:35:18The McFlurry spoon has a square handle on it.
00:35:22It gets attached directly to the ice cream machine, and the ice cream and toppings get
00:35:26mixed in together, right in your cup.
00:35:29It'd save the employees loads of time, plus it saves water because they don't have to
00:35:33wash the machine after each one.
00:35:36Wooden hangers are so hot right now, they could burn up your clothes.
00:35:41Nah, not really, but they look better and are more natural.
00:35:45But there's another reason to use them.
00:35:47They're made of cedar, which is a natural moth repellent.
00:35:51Bonus tip – add some dry orange peel to your closet.
00:35:55No moth is ever going in there again.
00:35:59Next time you're getting ready for work, take a closer look at your go-to shirt.
00:36:04Every buttonhole is stitched vertically, but check out the very last hole – it's stitched
00:36:08horizontally, right?
00:36:10This is because the bottom part of your shirt endures the most stress from pulling, as it's
00:36:15where your hips are.
00:36:16So that horizontal buttonhole isn't a mistake – it's put there to stop your shirt ripping
00:36:21as your hips move.
00:36:23That layer of bubbles that forms when you add bubble bath to your tub isn't just for
00:36:27fun.
00:36:28The bubbly layer also acts as insulation and keeps your bath warmer for longer.
00:36:33The pom-pom on top of your beanie wasn't put there as a fashion accessory.
00:36:37The pom-pom was originally added to the hat to prevent sailors banging their heads on
00:36:42the ceilings of the ships that were too low.
00:36:45Crackers have holes in them to stop them cracking and breaking during baking.
00:36:49If the holes weren't there, steam would build up inside the cracker and make it collapse.
00:36:55Those numbers on stickers they put on oranges aren't random.
00:36:59If there are four digits, and the first is 3 or 4, this means the fruit has been made
00:37:03with conventional farming techniques.
00:37:06Five numbers beginning with an 8 means the fruit has been genetically modified.
00:37:11Five numbers beginning with a 9 means the fruit is organic.
00:37:16Margins on paper aren't for writing in dates and numbering lists.
00:37:19They were originally added to serve a protective function.
00:37:23Back in the day, rats used to be a pesky problem in people's homes, and paper was one of their
00:37:27favorite snacks.
00:37:29Margins were added as a safeguard so that the rats would nibble on blank paper rather
00:37:33than taking a bite out of your important work.
00:37:37If you put your Chinese takeout on a plate when it arrives, you're doing more work than
00:37:41you should.
00:37:42Much like the paper condiment pots in fast-food restaurants, your cardboard Chinese takeout
00:37:48box can be unfolded to create the perfect size plate for your food.
00:37:53The long neck on your soda bottle is designed like that to encourage you to hold it there.
00:37:58That way, the heat from your hand will only warm that top bit of the bottle instead of
00:38:02heating up your whole drink.
00:38:06Why does a lapel have a buttonhole with no matching button?
00:38:09Originally, coats and jackets did have a corresponding button so that the wearer could turn up the
00:38:14collar and fasten it around the neck to keep warm.
00:38:17Over time, people stopped doing this, and the button was removed.
00:38:21But many suitmakers still keep the non-functioning traditional buttonhole.
00:38:25It's always hard to see your food in the microwave because of that pesky black grate
00:38:30on the window, but it's there to stop harmful microwaves escaping.
00:38:34Called the Faraday shield, it protects you as well as ensures that your food cooks properly.
00:38:41That random diamond on your backpack is called a lash tab or pig snout.
00:38:45It's there so you can thread cords through the holes to carry extra gear – perfect
00:38:50for camping or long hikes.
00:38:53Golf balls are covered in dimples, rather than being perfectly round, so that the ball
00:38:57can fly through the air more smoothly, decreasing the drag and allowing it to travel further
00:39:02and faster.
00:39:04Your makeup pads have two different sides for a reason.
00:39:07The bumpy side is used for applying makeup, while the flat side is for removing it.
00:39:13Donuts have holes so that the inside and outside cook evenly.
00:39:17Before the holes were added, the inside would often be greasy and doughy, while the outside
00:39:21was crisp.
00:39:23Your Apple laptop charger has tiny legs that can be folded out, and they're not there
00:39:28so your charger can stand up.
00:39:30These legs, when unfolded, allow you to wrap the cable around and then clamp it into place,
00:39:36securing it and preventing the cable getting tangled or damaged.
00:39:40Take a look at a soda bottle, and you'll notice a disc inside the bottle cap.
00:39:44This helps seal in the liquid and the drink's fizz, stopping it from going flat.
00:39:50That hole in your hollow lollipop stick isn't to prevent choking, should it ever be swallowed.
00:39:55It's actually there to keep the candy in place.
00:39:58Excess candy flows into the hollow tube, and the hole, which, when it hardens, keeps the
00:40:03pop in place.
00:40:04If it was a smooth stick, the candy would slide off easily.
00:40:09The zipper on leather biker jackets is often sewn diagonally.
00:40:12It's not just a fashion statement.
00:40:15Zips that are stitched vertically can bunch up if the wearer leans forward, but a diagonal
00:40:20zipper won't.
00:40:21That little triangle on your gas gauge is there to let you know which side of the car
00:40:25your gas cap is on.
00:40:27Now you'll never pull up to the wrong side of the pump in a rental car again!
00:40:33Vacuums come with so many attachments, but do any of us really know what that one with
00:40:38long bristles is for?
00:40:40It's for dusting and is perfect for cleaning framed art, blinds, and lampshades.
00:40:45Those tiny holes in the chocolate box tray actually serve a function.
00:40:50Push the hole near the candy, and it'll pop straight out with you having to get your
00:40:53hands dirty.
00:40:55How thoughtful!
00:40:56Some skyscrapers have hollow floors that can contain nothing but an elevator.
00:41:01It's actually a way to get around height limits.
00:41:04Some skyscrapers are given a limit to the number of floors they can have.
00:41:08Because the hollow floors are empty, they add to the height of the building and make
00:41:11it look more impressive without increasing the number of floors and breaking the building
00:41:15contract.
00:41:17These hollow floors also help to prevent the spread of fires.
00:41:21Women's shirt buttons are traditionally on the left for a reason.
00:41:25Back in the day, it was a sign of wealth as it signified that a chambermaid had dressed
00:41:30you, as having the buttons on the left made it easier for them to do up the shirt.
00:41:36Your cuticles serve a purpose, so think before you get rid of them.
00:41:39The small area of skin is there to protect your nails from infection.
00:41:43Without it, bacteria and fungi can get in.
00:41:46What's the difference between a wooden hanger and a plastic one?
00:41:51Aside from helping keep your clothes in shape, cedar wood hangers also repel moths and bugs.
00:41:58If you look closely at an elevator door, you'll notice a tiny hole.
00:42:02This is actually a keyhole used for emergencies or for routine maintenance checks.
00:42:08Those random buttons dotted across your jeans are called rivets and are placed in the weakest
00:42:13spots of the jeans to protect them from ripping due to strain or movement.
00:42:18The Statue of Liberty's crown has 7 points for a reason.
00:42:22They represent the 7 seas and 7 continents and were added so that she could extend her
00:42:27freedom to everyone on Earth.
00:42:30Cedars often come with 2 zippers so that you can connect them with a padlock to prevent
00:42:35theft.
00:42:36Salt isn't just used for cooking.
00:42:38It can get rid of tough smells.
00:42:40Rubbing salt on your fingertips after chopping garlic should remove the smell.
00:42:44It also works on shoes.
00:42:47If you're in a hurry to get somewhere, but your phone is low on charge, switch it to
00:42:51airplane mode while it's plugged in.
00:42:53It'll charge much faster.
00:42:57a loop on the back so that they can be hung on a hook in a dressing room or a locker room
00:43:02without creasing.
00:43:03Vaseline has a hidden purpose.
00:43:05It's great for removing scuffs from patent leather shoes.
00:43:08It'll also shine them.
00:43:11Trunks have an emergency latch if you ever accidentally lock yourself in.
00:43:15Like I do.
00:43:16Don't ask me why.
00:43:17If you fumble around to locate it, all you have to do is pull on it, and the trunk should
00:43:22open.
00:43:24Coasters have a secret slide in the bottom that can be removed so you can clean out all
00:43:29those annoying breadcrumbs.
00:43:31Take a look at your laptop keyboard.
00:43:33There are bumps on the F and J keys, but nowhere else.
00:43:37When your fingers are in the optimal typing position, your index fingers should rest on
00:43:41these two keys.
00:43:43The bumps have been added so that you can correctly position your hands for typing without
00:43:47looking at your keyboard.
00:43:49If you happen to be missing your index fingers, perhaps from feeding sharks a little too closely,
00:43:54then you're out of luck.
00:43:59You know, there are all sorts of amazing things you can do with products already lying around
00:44:04the house that were meant for other things.
00:44:07We'll explore some of those, plus everyday items that have other purposes you may not
00:44:13be aware of.
00:44:14I'm also in a silly mood, so hey, let's have some fun!
00:44:19Many pairs of kitchen scissors today have a serrated opening where the handles and blades
00:44:23meet.
00:44:24You can use this as an herb stripper to de-stem difficult herbs like thyme, rosemary, and
00:44:30chives.
00:44:31Saves you a lot of time trying to pick the leaves off by hand.
00:44:35And if you're short of a vase, you could present roses to your significant other this
00:44:40way.
00:44:41Just be careful when you're pointing the sharp end.
00:44:44The metal tab on soda cans can be flipped around.
00:44:47You can slip a straw in place so you don't have to hold it up to your mouth.
00:44:52The stay-on tab replaced the pull-ring tab created in the early 60s.
00:44:56You remember those, don't you?
00:44:59Those could be quite sharp and easily discarded where they could be a menace for others.
00:45:04Now you can pop your straw straight into one.
00:45:07Also means you can produce some bubbles and make a mess!
00:45:12Sometimes when you purchase an article of clothing, you receive a plastic baggie with
00:45:16an extra button and a swash of fabric.
00:45:20While the fabric is clearly used to patch holes, it can also be used to test the effects
00:45:25of various cleaners on certain surfaces.
00:45:27It's handy too to test wash cycles before using them to wash the whole garment.
00:45:34And if you want to clean your nose with it, that suggestion never came from me.
00:45:39You can use a screwdriver for leverage if you're having trouble lifting or moving
00:45:43something.
00:45:44Some also have a hexagonal-shaped handle that fits inside a wrench or spanner.
00:45:50You can use it to improve torque and, again, for leverage.
00:45:53A little easier on your hands.
00:45:55Some of us aren't that strong.
00:45:57Or maybe that's just me.
00:46:00Rubber bands are great for many things, but if you have a bottle that's hard to open,
00:46:04you can wrap the band around it for a better grip.
00:46:09Escalators have those fluffy black brushes for a similar reason that some have yellow
00:46:14lines on their steps.
00:46:16To try and deter people from getting too close to dangerous places.
00:46:20People don't always take notice, and sometimes clothing can drape close to a point where
00:46:24the step meets the edge or skirt.
00:46:27The brush is a little barrier to help prevent this from happening.
00:46:31They can also catch bits of fluff and prevent other small things from falling down into
00:46:36the gaps.
00:46:38Your average pair of jeans has several features that are both functional and somewhat sentimental.
00:46:45The metal rivets around the pockets help secure the stress points.
00:46:49This ensures they last a bit longer than average, though not all jeans have them.
00:46:55Many still have a tiny pocket directly above the main pocket.
00:46:59This was originally meant to hold a pocket watch.
00:47:02Even though pocket watches are mostly a thing of the past, many people still use this space
00:47:07to store coins, rings, or even a portable USB.
00:47:13This may seem a little obvious, but if you've ever wondered what all the notches are in
00:47:18a car tire, it's for traction on the road.
00:47:21However, they are also a good indicator if your tire is getting too worn down.
00:47:27If those notches aren't so deep anymore and are almost flush with the road, it's
00:47:32time to replace them.
00:47:33If you don't, the next time you try to stop suddenly at a stop sign, you might be
00:47:38surprised to find your car has turned into a giant roller skate.
00:47:43Those takeaway containers most associated with Chinese restaurants are designed to not
00:47:48only carry your food home, but to store them in the fridge.
00:47:53They double as a plate as you can eat straight out of them and don't have to worry about
00:47:57dirty dishes.
00:48:00They were actually patented way back in 1894 to transport freshly shucked oysters and were
00:48:06known as oyster pails.
00:48:08They were later adapted to use as leak-proof containers for food.
00:48:14While you're sitting on an airplane and looking out the window, you may have noticed
00:48:18those little holes, or in some instances, a small singular opening near the bottom.
00:48:23This is called a breather hole, and no, it's not for you.
00:48:27It's designed to equalize the difference in air pressure which builds up between the
00:48:31pressurized cabin and the atmosphere outside, especially during high altitudes.
00:48:38It also releases moisture from between the panes to avoid frost from forming on the windows
00:48:43and obstructing that all-important view.
00:48:46Sorry, but it looks like you won't be drawing a smiley face on it any time soon.
00:48:52This was first introduced way back in 1956 by a company in Japan.
00:48:57Pretty cool, huh?
00:48:58They got their inspiration from snap-off rows on chocolate bars.
00:49:02Just don't get the two mixed up.
00:49:05One doesn't taste good.
00:49:07When it comes to measuring tape, almost every reel has an empty slot in the metallic end.
00:49:13This is called a nail grab, so you can attach it to a nail or screw.
00:49:18A handy trick to do measurements without requiring someone else to hold it in place.
00:49:24Very nifty.
00:49:26Bobby pins have grooves on one side to hold your hair in place better.
00:49:31Crazy notion, huh?
00:49:32The straight side goes face up while the grooves go down against your head.
00:49:37They're called bobby pins because of the bobbed hairstyle which was popular in the
00:49:421920s, though the pins were invented in the 19th century.
00:49:46The look is gone, but the pins remain.
00:49:49Please take them out before you wash your hair as they don't look great stuck to your
00:49:54fingers.
00:49:56If you've been in a car or a bus and noticed the textured black dots baked into the black
00:50:01edges, you've probably worked out that it's not there for its pretty looks.
00:50:06It's called frit, a ceramic paint.
00:50:09Its main purpose is to protect the window from ultraviolet rays.
00:50:13It also creates a rough surface for the adhesive to cling to.
00:50:18If you see a pink lump of adhesive in the corner, please do not touch it.
00:50:23It's actually someone's old bubble gum.
00:50:27If you take a look at the bottom of the lock, chances are you'll see one or two little
00:50:32holes.
00:50:33This is to let water out from the inside that may have been trapped due to rain.
00:50:37This mini-draining capability prevents the inner working from rusting over or freezing
00:50:43in place if the weather's very cold.
00:50:46If in another situation the lock becomes stuck, you can ease an oil-based product inside to
00:50:52lubricate the lock and get it working again.
00:50:57If you've lost the key and want to ease your frustrations, you can yell into the holes.
00:51:02It won't do anything to unlock it, but it may help you feel a little better.
00:51:07Some dress shirts have a fabric loop on the back.
00:51:11You guessed it, it's used for hanging the shirt up.
00:51:14The loops were reportedly first used in the Navy, as it was easy to simply hang them on
00:51:19the wall.
00:51:21During the 1960s in colleges, the fashion of the day was to wear the shirt buttoned
00:51:26all the way to the top, which made them difficult to hang.
00:51:29So designers began putting the loop on the back.
00:51:33If the student removed the loop, it signified that they were going steady in a relationship.
00:51:38Unless your friend ripped one off for a prank, now everyone's asking whom you're with.
00:51:44There's a little more to this story, but we haven't got time to hang around.
00:51:49And yes, that's a bad pun.
00:51:51On purpose.
00:51:52It's what I do.
00:51:54Ever wondered why coins have those little ridges along the edge?
00:51:59It's a leftover from earlier times when they were worth more.
00:52:02Counterfeiters could easily file the edges off to sell as gold or silver coins to make
00:52:08some profit.
00:52:09The ridges were created so it was much easier to tell which of the coins had been altered.
00:52:14It's not needed today, but the coins still have that altered style.
00:52:19If you ever get really bored, you could try counting how many ridges there are.
00:52:24Actually, that is a very boring idea.
00:52:26Forget that and watch another Bright Side video instead.
00:52:33Have you ever stopped to think about the thrilling secrets of day-to-day modern life
00:52:38on planet Earth?
00:52:39I'm talking about tiny windows and washing machines, and little holes in airplane windows.
00:52:46If you haven't got a clue of what I'm talking about, tag along and allow yourself to be
00:52:51as surprised as I was when I found out.
00:52:56Remember the drawer at the bottom of your oven?
00:52:58Maybe you've been ignoring it all along or using it to store pots and pans.
00:53:03Well, even though it can serve this function, that's not the only thing it's there for.
00:53:08The best way to use the bottom drawer is to keep your meal heated while you're waiting
00:53:12to serve it.
00:53:13Genius, right?
00:53:16Talking about secret doors, have you noticed that most washing machines have little flap
00:53:21doors at the bottom too?
00:53:23These doors actually serve as drain traps.
00:53:26It's where all the items that we put to wash together with our jeans and jackets go to.
00:53:32It's a type of collector, let's say, of small items.
00:53:36It stops them from getting into the main drain pipes and clogging them.
00:53:40It saves us hundreds of dollars in repairs each month.
00:53:44Now, who hasn't gone through the confusing task of having to measure how much pasta to
00:53:50cook for one serving?
00:53:52Well, here's the solution.
00:53:54The holes in the center of pasta spoons.
00:53:57They were actually made for measuring the exact amount of dry pasta you need for one
00:54:01serving.
00:54:03If you try stuffing wet cooked pasta through it, well, good luck with that.
00:54:09On a similar topic, have you ever wondered why pen caps have holes in them?
00:54:14Maybe you thought it was a design feature to regulate air pressure.
00:54:18But in reality, these holes have a much simpler and more important function – to reduce
00:54:23the risk of choking.
00:54:26Lots of people love to bite on their caps, and this tiny hole prevents them from choking
00:54:31in case they accidentally swallow a cap and it gets stuck in their throat.
00:54:36For kitchen lovers, there's a hidden secret right in front of your eyes that can change
00:54:40your life.
00:54:42Think pans, now think handles.
00:54:45Right, they have holes in them!
00:54:47As it turns out, these holes were designed to hold the spoon you're using for cooking.
00:54:52And instead of dripping sauce all over the stove or your kitchen floor, you can place
00:54:57the spoon in the hole and let it drip the sauce directly back into the pan.
00:55:04Speaking of everyday items, and I was, most doorknobs are made of brass because this material
00:55:11makes them naturally germ-free.
00:55:14Unlike plastic ones, brass doorknobs are kind of magical.
00:55:19They can disinfect themselves without you having to clean them.
00:55:22Neat, right?
00:55:25Have you ever noticed that at the bottom of a measuring tape, there is a little dip?
00:55:30You can find it in that metallic part you need to pull on to measure something.
00:55:34Well, that dip is actually the exact size of a regular nail.
00:55:39It was designed for people to place the tape on top of a nail and use it as a support while
00:55:45they stretch the tape.
00:55:46Well, I can't wait to try it out for myself!
00:55:50As for the margins in your notebook, they were invented to protect people's notes
00:55:55from mice.
00:55:56No, the mice weren't copying your answers for the math quiz.
00:56:01Actually, there were times when people had to cohabitate with rats and mice that often
00:56:06chewed on paper.
00:56:08So to prevent information from getting completely lost, people created margins.
00:56:14This way, texts were moved closer to the middle of pages and remained unharmed by rodents.
00:56:21Perhaps this is where to-digest information came from.
00:56:27And what about those tiny holes at the bottom of airplane windows?
00:56:31They have an extremely important function of regulating the air pressure inside the
00:56:36cabin.
00:56:37In other words, they help planes fly high up in the sky.
00:56:41Big responsibility, right?
00:56:44By the way, tray tables on an airplane are the germiest places inside the entire cabin.
00:56:50Studies showed that the trays had 8 times the amount of germs on the toilet flush button.
00:56:57Now, how about we cut a commercial airplane in half and see what's inside?
00:57:03Well, it would look more or less like this – rows of seats on top and everything else
00:57:09that needs to be stored at the bottom.
00:57:11I'm talking about passengers' luggage, emergency supplies, parts of the wing system,
00:57:16and so on.
00:57:19Moving on to bowling balls.
00:57:21Yes, I know it's a clumsy transition.
00:57:24Anyway, have you ever wondered what the insides of a bowling ball look like?
00:57:30If you have cut a professional ball in two, you'll see a familiar shape.
00:57:35Look closely, do you see it?
00:57:37Doesn't that look like the logo of Brightside?
00:57:40Anyway, professional bowling balls are different from the ones in your local bowling alley.
00:57:45That's because they're designed to make fancy moves.
00:57:48They actually have some really complex engineering inside.
00:57:51They're shaped to help skilled professionals get more strikes.
00:57:56The weight of professional bowling balls is designed to be projected inward as they travel
00:58:00down the bowling lane.
00:58:02This makes it harder for them to get into the gutters on the sides of the lane.
00:58:08Speaking of balls, let's take a look inside a baseball.
00:58:12To make it light and aerodynamic, producers use several different layers.
00:58:17Starting from the core, we have a cork center enveloped by black rubber.
00:58:22Then there's a layer of red rubber followed by two or three alternating layers of wool
00:58:27yarn.
00:58:29After that, there's a visible white leather cover and that beautiful red seam on the side,
00:58:34stitching it all together.
00:58:37And what if you had X-ray vision and managed to look inside a human bone?
00:58:43Spooky!
00:58:44I'd say what calls most attention is this spiderweb-like situation at the center of
00:58:50the bone.
00:58:51In reality, it's a highly condensed and complex structure of nerves that you have
00:58:56inside your bones.
00:58:57Aren't you lucky?
00:59:00Now I've got a riddle for you.
00:59:02What is round, can be found near the ocean, and looks like an aerial view of the Guggenheim
00:59:07Museum in New York City – the one that's made almost entirely of ramps.
00:59:12If you said a nautilus shell, then you guessed right!
00:59:17A nautilus is a shellfish whose house you can find in countless souvenir stores near
00:59:22the beach.
00:59:23It's made up of two layers – a matte white outer layer and an iridescent white inner
00:59:29layer.
00:59:30And if you were to cut it in half, it would look very similar to the insides of the Guggenheim
00:59:35Museum.
00:59:37Aloe leaves are good for healing purposes and also for hydration.
00:59:42But if you managed to look inside of an aloe leaf, the image you'd see would be satisfying
00:59:47and very relaxing.
00:59:49Who hasn't dreamed of a pool filled with jelly?
00:59:54There seems to be nothing more mundane and regular than a tube of toothpaste.
01:00:00But you wouldn't think so if you cut open a tube that contains several colors.
01:00:04Now there have been speculations that the insides of such a toothpaste tube might be
01:00:09divided by barriers so that the stripes don't mix.
01:00:14If you cut it in half, you'll see that it has only one interior chamber.
01:00:20As it happens, there's a lot of science behind the making of striped toothpaste.
01:00:25According to a specialist, they have to ensure that the paste in all the stripes has the
01:00:29same physical properties.
01:00:31This way, the colors are naturally prevented from mixing with one another.
01:00:35That's why, if you tear a tube open, you'll see something that looks like several slices
01:00:40of pizza in different colors.
01:00:44If you open your closet, you're bound to find at least a few wooden hangers.
01:00:48Usually they're made of cedar wood, which is a natural moth repellent.
01:00:53So cedar hangers actually protect your clothes from moth infestation.
01:00:59For some people, more than others, eyeliner is an everyday must, boy isn't it?
01:01:05But did you know that back in ancient Egyptian times, both men and women used coral eyeliners
01:01:11to protect their eyes from the sun's glare?
01:01:14Way to go for the Egyptians for figuring that out!
01:01:17Now if I could just learn to walk like one…
01:01:21Normally, we use headrests for the purpose of, well, resting our heads, right?
01:01:27Well, not only.
01:01:29As it turns out, headrests can be easily removed from the seats and used to break car windows
01:01:35in case of emergencies.
01:01:39This one is a trick very few people know about.
01:01:42You probably place your doormat horizontally, like most of us do.
01:01:46But doormats serve the purpose of absorbing dirt from the soles of your shoes before you
01:01:51enter your home.
01:01:53So for this function to work as it's meant to, the best way to place a doormat is vertically.
01:01:59This way, you take more steps on the top of the doormat before entering your house.
01:02:06And last but not least…
01:02:08Now I don't want to be accusatory here, but you have probably been vacuuming your
01:02:12house the wrong way, and I can prove it.
01:02:16Most people just vacuum floors and carpets in one direction or move the brush back and
01:02:21forth several times, thinking they've got all the dust out.
01:02:25But according to cleaning professionals, the best way to vacuum is in rows.
01:02:31First you go forward with the brush until you arrive at the end of the row.
01:02:35Then you fluff the carpet up and move back down along the same row, gathering the dust
01:02:40that wasn't collected in the first sweep.
01:02:43Talk about efficient cleaning!
01:02:45On the other hand, my idea of house cleaning is to sweep the room with a glance.
01:02:50Hey, I don't want to disturb that protective layer of dust!
01:02:57Road and construction workers are usually dressed in orange because the bright orange
01:03:01hue is visible even in bad weather.
01:03:04It's the most effective color to attract attention and alert people.
01:03:07No wonder lots of safety jackets and traffic cones are orange as well.
01:03:11The stop sign has an eight-sided shape to help drivers recognize it easily, even if
01:03:16they see it from the back.
01:03:17And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing
01:03:22the stop sign with any other at night.
01:03:25The rumble strips on the side of the road are placed there to alert drivers who doze
01:03:29off behind the wheel.
01:03:31When their tires move over these strips, the noise and vibration work like an alarm clock.
01:03:36There are magnetic locks on fuel hoses at gas stations.
01:03:40They come in handy if someone drives away with the gas nozzle still attached to their
01:03:44car.
01:03:45In this case, the lock detaches the hose automatically.
01:03:47Oh, that's embarrassing!
01:03:50Gasoline looks like a rainbow in a puddle because it can't mix with water.
01:03:54It forms a thin membrane over it.
01:03:56When light reflects from it and the water at the same time, you've got a rainbow.
01:04:02A triple handle on a jerry can is there to make it easier for two people to carry it
01:04:06and distribute fuel evenly.
01:04:09Gas cans often have a second hole that actually needs to be uncapped too before you pour the
01:04:13gas.
01:04:14The air passage will prevent it from pouring out, so no more fuel waste.
01:04:19Most gas cans have two holes with caps, a bigger and a smaller one.
01:04:24They're supposed to uncap the smaller hole before pouring gas inside the bigger one.
01:04:28It'll prevent the liquid from glugging and spilling all over your clothes and the ground.
01:04:33Another little thingy we often neglect is a point on an ointment cap.
01:04:38Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails
01:04:43isn't the best idea.
01:04:44A point easily opens even the most safely sealed tube.
01:04:49You can use most screwdrivers together with a wrench to create more torque.
01:04:54Just place the wrench over the handle of the screwdriver.
01:04:57This way, you'll need to apply a lot less force than before.
01:05:01You'll also be able to get to hard-to-reach areas more easily.
01:05:05They install cameras in shops, banks and hospitals to monitor everything.
01:05:10If something happens, you can call the police or rescuers.
01:05:14The camera really helps to solve a lot of problems.
01:05:16Why are there no cameras on planes?
01:05:20The crew keep order on the plane, but they won't be able to do anything if something
01:05:23serious happens.
01:05:25Besides, there's nowhere to run on the plane.
01:05:28During the flight, the cameras are useless, and after the flight, the words of the passengers
01:05:33work ideally instead of cameras.
01:05:35So if cameras do no good, then why spend money on them?
01:05:40Water is great at cleaning stuff because it has triangular molecules.
01:05:44They're made of one oxygen and two hydrogen atoms, um, H2O.
01:05:49Such molecules have slightly different charges on their opposite sides, pretty much like
01:05:53magnets.
01:05:54That's why water easily sticks to other molecules, including those that make up dirt.
01:05:59Lots of private houses have triangular-shaped roofs because this allows rain, snow and fallen
01:06:04leaves to slide off the slope.
01:06:06If all this stuff piled up on top of your house, one day your roof would collapse.
01:06:12When a storm is coming, clouds seem to turn dark, but it's just an illusion.
01:06:16Thin clouds on a sunny day let the light through easily.
01:06:20They also scatter all the colors of the light spectrum.
01:06:23This makes us perceive the clouds as white, but the thicker the clouds are and the more
01:06:27water droplets they contain, the less light they let through and the darker they look.
01:06:33A good doorknob is the one made of brass, bronze or some copper alloys.
01:06:39These metals have an anti-germ effect.
01:06:42They spread way slower on them.
01:06:44They also get rid of germs pretty fast, within a couple of hours.
01:06:48Nope, it doesn't mean you don't have to wash your hands.
01:06:52Diamonds have such symmetrical shape to show you their brilliance.
01:06:55Initially, the gems aren't so beautiful.
01:06:58They go through several stages of cutting and then become pieces of elegance.
01:07:03Most of these stones have a round shape with slightly pointed corners.
01:07:07Diamonds shine the brightest in this shape.
01:07:11Why are there two holes in the socket?
01:07:13The left hole is neutral.
01:07:14The right hole is not.
01:07:17And the gap underneath is ground.
01:07:19Electricity needs to flow through the chain.
01:07:22The current flows from the hot slot, passes through your phone charger, for example, and
01:07:26then goes through the neutral hole.
01:07:29Ever wondered what that small pocket on your jeans is for?
01:07:32People used to wear watches on chains.
01:07:34That small pocket was meant for it.
01:07:37Now, almost no one wears such a watch, but the pocket remains.
01:07:41You can still keep something small in there like a ring.
01:07:44In London, there are some poles that look like street lamps, but there are no bulbs.
01:07:49Well, their official name is stink pipes, and they're a thing of the past now.
01:07:54But they used to come in handy back in the 19th century.
01:07:57These hollow poles would vent away the air and explosive gases with bad smells to prevent,
01:08:02shall we say, unwanted consequences.
01:08:06Some kitchen shears have metal plier-like teeth in the middle.
01:08:09Between the handle grips, they can help you crack nuts, crab shells, and other tough products.
01:08:15You can also open jars and bottles or remove herb stems with their help.
01:08:21Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and
01:08:25scrapes.
01:08:26They scatter the light that hits the material.
01:08:28When you coat your shoes in a layer of wax, you fill these tiny crevices.
01:08:33The surface becomes smoother, and the rays of light bounce off it more evenly.
01:08:37That's why the leather looks shiny.
01:08:40Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.
01:08:47Yellow and light green hues are the most popular because they don't prevent you from seeing
01:08:51the text after black-and-white photocopying.
01:08:55Photocopiers perceive yellow and light green marks as very pale and don't print them.
01:09:00They make magnets shaped as a horseshoe because this increases the magnetic force.
01:09:05Colors matter, too.
01:09:06The blue part indicates the south pole.
01:09:08The red part, the north pole.
01:09:11The two poles work simultaneously and increase the attraction force.
01:09:16The dime-sized holes in elevator doors is actually a keyhole.
01:09:20If the doors get stuck, an operator can open them manually thanks to this hole.
01:09:24They'll just insert a special key.
01:09:28The tiny hole in the airplane window is there to balance air pressure.
01:09:32The window has three layers.
01:09:34The outer pane is extremely sturdy.
01:09:37It can withstand air pressure differences during takeoff and landing.
01:09:41The inner pane, which is the closest to you, is made of cheaper materials.
01:09:45It prevents potential damage to the window.
01:09:47The hole itself is in the middle pane.
01:09:50It not only balances the pressure but also prevents the window from fogging.
01:09:56Escalator brushes are there for your safety.
01:09:58They don't allow you to come too close to the edge of the escalator.
01:10:02This way, your clothes won't end up between the steps.
01:10:05You see the sun as yellow or orange because the atmosphere of our planet scatters such
01:10:10colors as blue, green, and violet.
01:10:13This is also why the sun looks warmer at sunrise and sunset.
01:10:18Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.
01:10:22You'll rarely see them lying around without one of those.
01:10:25It's pure marketing and that color isn't a random choice.
01:10:28When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to
01:10:34you.
01:10:35So, you're more likely to buy them, right?
01:10:38Lemons are usually sold in green mesh bags for a similar reason.
01:10:41If you pack them in red, they'll appear more orange.
01:10:45Green goes better with yellow and makes those lemons stand out.
01:10:49Mattress manufacturers make a limited number of different mattresses and the only way to
01:10:53make them look different is to come up with a fancy stitching pattern.
01:10:57Two mattresses of two different companies might be the exact same quality but cost differently.
01:11:03Most people will never know it and will decide that different patterns mean something in
01:11:07terms of quality.
01:11:08So, when shopping, don't mind the pattern at all.
01:11:13Almost all hotels have white bed sheets.
01:11:15They choose this color specifically to show how high their standards of cleanliness are.
01:11:20The whiter and brighter the sheets are, the more luxurious the hotel seems.
01:11:24It's much easier to see dirt and stains on white linen.
01:11:27It's like proof that you've checked into a clean room.
01:11:30So, consider this.
01:11:33People started making ridge patterns on coins in past centuries to fight counterfeiters.
01:11:38In the old days, cheaters cut off the smooth edges of coins and used that metal to mint
01:11:43new money.
01:11:44But with ridges, it became impossible to hide the cutting.
01:11:48These small cylinders on the charging cables are called chokes or ferrite cores.
01:11:53They're magnetic iron oxide that helps to prevent electromagnetic interference.
01:11:58In simple words, they protect your device from faults.
01:12:02We all know about these little pockets on jeans where people used to keep their pocket
01:12:06watches.
01:12:07But what about these small metal buttons?
01:12:10They help hold the fabric together.
01:12:12Weavers put the buttons where the jeans can tear during moving and straining.
01:12:17These small holes on some backpacks were designed to tie extra gear to them.
01:12:21So, you can pass ropes through them and tie sneakers if you don't want to keep them
01:12:25inside your backpack or in your hands.
01:12:28This tiny dot next to the camera on your iPhone is a microphone.
01:12:33It helps to get good quality of sound while taking a video.
01:12:37The spotlight feature on your Mac can be used not only for a quick search of files and apps.
01:12:43It also works as a calculator.
01:12:45Just type in a mathematical problem you need to solve.
01:12:49Spotlight also uses internal dictionary data.
01:12:52Enter any word in the search bar, and you can get information about it.
01:12:56You've just bought a new bottle of oil.
01:12:58You're taking off the lid and looking at this little cork that you can tear off by
01:13:02pulling the loop.
01:13:04Take this thing out, but don't throw it in the trash.
01:13:07Put it back in an upside-down position to control the pore's flow by pressing your
01:13:12finger against it.
01:13:14Tiny ridges on the F and J keys on the keyboard help your fingers navigate during touch typing.
01:13:21When your index fingers are on these ridges, you know exactly where other letters are.
01:13:26The brushes on the sides of the escalators are not for polishing your shoes, but for
01:13:31your safety.
01:13:32These nylon bristles prevent your laces and clothes from getting inside the escalator's
01:13:37gears.
01:13:38Now, that wouldn't be good.
01:13:40Most door handles are made of brass.
01:13:43This type of metal is good for fighting microbes.
01:13:46Bacteria can't multiply that much on such surfaces.
01:13:50These public toilets' cubicles don't look private for a reason.
01:13:54Huge gaps at the bottom were created to make you want to get out of there as soon as possible.
01:13:59Thanks to this design, there are almost no queues.
01:14:03You can use a plastic lid from soda cups as a coaster.
01:14:07It has the perfect shape to hold your drink and keep a table surface from getting wet.
01:14:12Don't turn the lid upside down.
01:14:14Just put it on the table the same way it was on the cup.
01:14:17If you're stuck in a car during an accident and can't open the doors, you can use bars
01:14:22from the detachable headrest to break the window and get out.
01:14:27Remember those small plastic discs under the bottle lids?
01:14:31This little thing helps preserve vacuum inside bottles, keeping soda in a fizzy state.
01:14:37You've probably watched food heating in a microwave at least once in your life.
01:14:41Exciting!
01:14:42I know!
01:14:43But why do the developers make the doors so dark?
01:14:46This black film is necessary to block electromagnetic fields.
01:14:51Tiny dots on padlocks next to the keyhole are designed to dry out the moisture if water
01:14:56gets inside the lock.
01:14:58Also, if the lock gets jammed or starts to rust, you can pour oil into it through this
01:15:03hole to fix the problem.
01:15:06A golf ball is covered with tiny craters for good aerodynamics.
01:15:10They're called dimples, and this design helps the ball fly further and more evenly.
01:15:16Some mugs have a little groove at the outside of the bottom.
01:15:20It helps water flow out and prevents it from accumulating when the cup is in the dishwasher.
01:15:26Sunglasses were first used not to protect your eyes from the sun.
01:15:30They use such glasses during Arctic expeditions.
01:15:33A huge amount of snow can blind you just like a bright flash.
01:15:37To save their eyes, they came up with these unique glasses.
01:15:41You can use any t-shirt not only for dressing but also as a protective layer for your luggage.
01:15:47Just put your clothes on your suitcase as a cover and don't waste time plastic-wrapping
01:15:52it.
01:15:53A button on the back of the shirt collar is there to keep your tie under the collar.
01:15:57Yes, people don't use it as intended because all ties are thinner now.
01:16:02But this button is still there as a decorative function.
01:16:06And here's the initial purpose of a tie.
01:16:08They created it in 17th-century Europe to tighten the collar.
01:16:13This way, people protected their necks from a strong wind.
01:16:16Then, they got used to this part of the outfit and made it a must-have accessory for royal
01:16:21gatherings.
01:16:23Soft pom-poms on hats were first invented several centuries ago.
01:16:28Sailors used them to avoid hitting their heads against low ship ceilings and ledges.
01:16:33They make most clothes hangers from cedar wood since it contains many natural oils repelling
01:16:38moths that love to eat your clothes.
01:16:42A light bulb is spherical because such a shape allows the light to distribute evenly.
01:16:47Also, such light bulbs are cheaper and easier to produce.
01:16:51Ever found these pieces of fabric in new clothes?
01:16:54They're not just patches but also testing subjects to use before washing.
01:16:59You can put this piece in the washing machine and see what happens to it.
01:17:03If everything is fine, then you can safely put your clothes in.
01:17:08Your ceiling fan has two modes of work – winter and summer.
01:17:12You need to find the switch on it.
01:17:14Push it up to activate the winter mode and down for the summer one.
01:17:18In summer mode, the fan pushes the air down.
01:17:21It pulls the air up in winter.
01:17:25Most people have this ground plunger in the bathroom.
01:17:28In movies, they use those to eliminate a blockage in the toilet.
01:17:32In fact, the plunger is to get rid of a blockage in the sink.
01:17:35For the toilet, you need another special device.
01:17:39The extra space under your oven is not for keeping pans and pots.
01:17:44You can put some dishes there.
01:17:46The heat of the stove will keep your meals warm.
01:17:48It's useful if you're waiting for friends late for dinner.
01:17:53You're taking a pack of popcorn out of a microwave after heating.
01:17:57See the little hole at the top of the popcorn bag?
01:18:00You can use it to get rid of small unpopped grains.
01:18:04Shake the pack over the plate, and all the grains will fall out through the hole.
01:18:09Almost all people use a travel pillow incorrectly.
01:18:12Usually they put two ends forward and lay their heads back.
01:18:16Try to turn the pillow on the other side.
01:18:19The arc should be under your chin, and the two ends should be directed back.
01:18:23Lay your head forward, and your neck will feel way more comfortable in this position.
01:18:28And you'll get a good nap.
01:18:31They create magnets in a horseshoe shape to increase their magnetic power.
01:18:35The blue part indicates the south pole, the red part the north one.
01:18:40The two poles work simultaneously and increase the attraction.
01:18:44Thanks to the perfect aviation design, most planes can fly a long distance even without
01:18:50an engine.
01:18:52In 1268, Roger Bacon made the first written mention on using telescope lenses for optical
01:18:58purposes.
01:19:00Magnifying lenses inserted in frames were popular for reading both in Europe and China
01:19:04at this time.
01:19:05So it's still a question if the West took it from the East or vice versa.
01:19:11If you find yourself in the middle of the sea without food, sorry, you can try fishing.
01:19:17You can use anything for bait.
01:19:18Your phone, watch, keys.
01:19:20And you can use laces as a fishing line.
01:19:23Tie the bait and throw it into the water.
01:19:26And good luck catching the fish that swallowed your phone.
01:19:29It's going to be a whopper.
01:19:31You can turn over the tab on a lid of soda cans, and use it to hold a cocktail straw
01:19:36in place.
01:19:38The blue half of the eraser wasn't originally created to delete the ink.
01:19:42Initially, the blue part erased inscriptions and drawings on thick paper.
01:19:46The red part couldn't do it without leaving streets.
01:19:49But the blue one handled this task perfectly.
01:19:53Most of us tear sticking notes off incorrectly.
01:19:56Try not to do it from below, but from the side along the licking lock.
01:20:01The paper will stick to the wall for longer this way.
01:20:05Ever wondered what these two holes in the lollipop stick are for?
01:20:08All the time, you say!
01:20:10Well, when they put the bar in hot syrup, the liquid flows inside.
01:20:16It creates a solid attachment for the plastic.
01:20:19And so it goes.
01:20:23Over 40 billion Oreos are made every single year.
01:20:26It's the world's most popular manufactured cookie.
01:20:30The geometric design stamped into these cookies has the Nabisco logo, the symbol of European
01:20:35quality, surrounding the word Oreo.
01:20:38William Tournier created the chocolate cookie design we see today back in 1952.
01:20:44Headphone jacks might become a thing of the past because of wireless technology.
01:20:49But if you've seen one, you might've noticed the rings at the base of the plug.
01:20:54One ring means single-sound playback, two rings represent stereo sound in the left and
01:20:59right ear, while three rings means you've got stereo and a microphone built in.
01:21:04Now the iconic orange, red, purple, yellow, and lime green rings of Froot Loops hide a
01:21:10deep secret within.
01:21:12They don't represent different fruit flavors.
01:21:15All those rings are the same fruit flavors blended together.
01:21:18The colors are just for show.
01:21:22The E in Dell's logo is at an angle because the founder, Michael Dell, wanted his technology
01:21:28to turn the world on its ear.
01:21:31A compass uses magnets to point to the magnetic North Pole.
01:21:34But it's not really north at all.
01:21:37The North Pole of a compass magnet points toward the North because the North and South
01:21:41attract.
01:21:42Earth's South magnetic pole is near the geographic North, while the North Pole is
01:21:47near Earth's geographic South.
01:21:50Confusing, isn't it?
01:21:52Those little red spots you sometimes see after you crack an egg are nothing to be worried
01:21:57about.
01:21:58Tiny blood spots can be caused by a small rupture in the blood vessel of the hen as
01:22:02it was laying the egg.
01:22:04Eggs with these blood spots are safe to eat, but that spot can be removed if you want.
01:22:09It won't affect the taste of the egg.
01:22:12That's comforting.
01:22:14Ketchup is a word taken from many cultures, like Chinese, Malay, and Indonesian.
01:22:19It originally meant a pickled fish sauce.
01:22:23Ketchup is also an acceptable spelling use.
01:22:25However, ketchup is the most popular way it's spelled these days.
01:22:30Airbnb's logo isn't a bent paperclip as it may seem to be.
01:22:35Bello, as it's called, for belonging, means more than that.
01:22:39There's a person's head, the location symbol, and a heart for love.
01:22:43All joined together, they make Airbnb's iconic A and symbol of togetherness.
01:22:49E120 or Natural Red 4 food coloring, aka carmine, is made from tiny beetles.
01:22:56It's been used to color anything from cakes to candy to even drinks.
01:23:02That shine on candy also comes from bugs.
01:23:05This time, it's the Indian female lac bug.
01:23:08The beetle leaves behind a substance that is scraped from the trees to be formed into
01:23:12dry shellac that gives that glossy look.
01:23:17The Mozilla Firefox logo isn't a fox at all surrounding the planet.
01:23:21It's a red panda instead.
01:23:23The name Firefox is the English translation of its Chinese name.
01:23:28Those maintenance covers in the street are round for safety reasons.
01:23:32In past civilizations, like Ancient Rome, manholes – that's what they were called
01:23:37back then – were square-shaped slabs of stone.
01:23:40Unfortunately, these were prone to accidents.
01:23:43If they weren't placed properly, a square cover could slip through the square hole diagonally.
01:23:48Ow!
01:23:49Placing a round cover eliminated this problem.
01:23:52A circle cover won't slip inside because there are no angles.
01:23:57A tomato isn't technically a vegetable, but a fruit.
01:24:01Banana trees aren't related to palm trees or trees at all – they're herbs.
01:24:06Banana is considered an herb because it never builds a woody trunk the way a tree does.
01:24:11Instead, it forms a succulent stalk like lemongrass or its cousin, ginger.
01:24:16You can call them berries as well.
01:24:19The Golden Gate Bridge color wasn't meant to be the orangey-red that it is today.
01:24:24The bridge's original color was suggested to be many other colors, such as black with
01:24:29yellow stripes or even candy cane to make it visible for passing ships and aircraft,
01:24:35especially in the frequent San Francisco fog.
01:24:39But when the steel arrived covered in an orange primer to protect it from rust, the architect
01:24:45preferred the international orange color, and it stuck.
01:24:50Those legs on the back of keyboards aren't an ergonomic design to help your wrists sit
01:24:54better.
01:24:55Using the legs out for too long can tire and hurt your wrists, plus slowing your typing
01:25:00down.
01:25:01The hinge legs are just there to help you see the letters and numbers better if you
01:25:06don't know how to touch type.
01:25:08The color of a chili pepper reveals nothing about its taste or heat.
01:25:13The smaller a chili is, the hotter it'll usually be.
01:25:17The heat doesn't come from the seeds, as believed, but the white membranes that hold
01:25:21them.
01:25:23Hidden within the Toblerone logo of the mountain is the image of a bear standing on its hind
01:25:28legs about to eat that yodeler over there.
01:25:31No, not really.
01:25:33This is because bears are a big part of Bern, one of the biggest cities in Switzerland where
01:25:37the founder created the triangle chocolate tree.
01:25:41Toblerone is also a play on the founder's family name, Tobler, and the Italian word
01:25:46Torrone, for honey and almond nougat.
01:25:49The space below a cup of noodles is there to protect the noodles during transport.
01:25:54This technique is called a middle suspension.
01:25:57Not only are they protected better in their styrofoam cup, but it also helps those noodles
01:26:02soften more evenly and quickly.
01:26:05Even though you might've thought that the hole in the barrel of a ballpoint pen had
01:26:09no purpose, it does!
01:26:12It's called a venting system, which helps the ink flow more smoothly.
01:26:16This way, an even amount of air pressure is created inside and outside the pen, allowing
01:26:22the ink to flow into the point easily.
01:26:25One of the most recognized logos in the cycling world has a hidden item in its famous logo.
01:26:31Inside the Tour de France name, a cyclist hides in the O, U, and R.
01:26:38Those metal brackets on the top of the nozzles in gas stations have a unique design put into
01:26:43place in case of accidents.
01:26:45If a dodo accidentally forgets the nozzle is still inside the gas tank and starts driving
01:26:51away, the magnetic brackets separate without damaging any part of the gas pump.
01:26:57Wendy's logo is designed off of the daughter of creator Dave Thomas.
01:27:01It's also named after her nickname, but there is more to the logo than that.
01:27:07Wendy's collar spells out the word mom.
01:27:10While unintentional, it became something to mean a homey feel, more than any other restaurant
01:27:15out there.
01:27:17Finding the right lane to be in while driving for your exit can sometimes be confusing,
01:27:22especially in a foreign country.
01:27:24Pay attention to the side of the road that exit signs are located.
01:27:28It'll be the lane you need to be in.
01:27:31Some toothpaste has a little seal on them that needs to be removed before you can use
01:27:36them.
01:27:37Instead of peeling back the foil layer, the toothpaste lid has a little spike on the top
01:27:42just for this reason.
01:27:45Tostitos have a secret symbol hidden right in the middle of their name.
01:27:49The two T's in the middle of the logo resemble two people enjoying tostitos over a bowl of
01:27:54salsa.
01:27:55The salsa bowl is in red and forms the dot in the I.
01:28:00One of the most recognizable figures in the world, the Statue of Liberty, for 16 years
01:28:05functioned as a fully operational lighthouse.
01:28:08However, the light was barely visible even from Manhattan.
01:28:13In 1901, it was eventually decommissioned as a lighthouse.
01:28:17Tourists could even visit the torch for a stunning view of the city.
01:28:21But an accident damaged the Statue of Liberty's torch in 1916, and it's been closed to the
01:28:26public ever since.
01:28:29The Do Not Remove Under Penalty of Law tag on mattresses isn't put there for the consumer
01:28:34or void your warranty either if you do remove them.
01:28:38In the 1900s, manufacturers used to create the filling with basically anything.
01:28:44Animal hair, old hospital beds, or clothing.
01:28:47It didn't matter at the time.
01:28:49Strict laws created the tags to stop recycled materials from being used and sold as new.
01:28:55Good thing!
01:28:56Toyota's symbol is more than just some random rings combined.
01:29:00The three overlapping ovals symbolize the merge of the hearts of consumers and Toyota
01:29:05together.
01:29:06A California sushi roll is made of seaweed, rice, cucumber, avocado, and crab meat.
01:29:14But it's not crab meat at all.
01:29:16Serrini is an imitation crab meat.
01:29:19It's made of white fish blended with sugar instead of crustaceans.
01:29:23The fish mixture is then heated and pressed into shape.
01:29:27The logo for Beats is just a lowercase b inside of a red circle.
01:29:31The circle represents a human head, with the b being the headphones in their shape.
01:29:37All those little black dots around the edges of car windows are called frits.
01:29:42A frit is a painted black enamel that's put into windshields during manufacturing.
01:29:47They block ultraviolet rays and help distribute temperatures between the metal and glass.
01:29:53There are 24 symbols hidden inside the Unilever logo.
01:29:56Let's count, shall we?
01:29:58The sun, dove, plant, spark, chili pepper, spoon, bowl, flower, ice cream, hand, hair,
01:30:08lips, swirl, fish, clothes, bee, particles, packaging, transformation, waves, DNA, palm
01:30:17trees, heart, and virtuous cycle.
01:30:22These represent everything that the company believes in and produces.
01:30:26DNA?
01:30:27Bobby pins are designed so that the zigzag part goes onto your scalp, not the flat part.
01:30:33It gives a greater grip on the hair and skin, making the pins stay in longer.
01:30:38The story that the pins were named after those fashionable London constables, called bobbies,
01:30:43is not true.
01:30:45I made it up.
01:30:49Pouring milk into your tea or coffee can make a mess if you don't do it the right
01:30:53way.
01:30:57If you want to pour it with the opening closer to the cup, stop right there, turn it to the
01:31:02other side, and then pour.
01:31:04The flow will be much smoother this way, and you won't have to deal with wiping the table
01:31:09afterwards.
01:31:10Hey, I'm bossy, get over it.
01:31:12It's all about the physics of it.
01:31:14If you turn the carton's opening toward the cup, and the carton is full, while the milk's
01:31:19escaping through the opening, the air from the outside will try to get inside the carton
01:31:24to fill the empty space.
01:31:26Since there's only one place where it can do that, the air will push the milk back and
01:31:30disrupt the flow.
01:31:32When you turn the carton to the other side, there will be empty space along with the top
01:31:36side of the carton, and the air will have it easier getting inside.
01:31:41So the flow will be steady, and you won't have that annoying spurting anymore.
01:31:46The handrails are usually moving faster than the escalator itself, because the gear wheels
01:31:51that drive the handrails are intentionally made a bit larger than required.
01:31:56The rubber on those wheels tends to wear off with time, so if the handrails are moving
01:32:01at the same speed as the steps, or even slower, then you're riding a rather old escalator.
01:32:07Now speaking of escalators, and I was, at subway stations with three or more of them,
01:32:13the majority will be going in a different direction depending on the time of day.
01:32:17For example, in the city center, there will be two or more escalators going up in the
01:32:21morning and down in the evening, and vice versa at the outskirts.
01:32:26This is done to make it easier for passengers to get around.
01:32:29Most people only work downtown while living far from the center, so they go to work in
01:32:34the morning and find more escalators moving in the direction they need.
01:32:39How convenient!
01:32:41If you were ever worried about how the pilots find their way in the dark when landing at
01:32:46night, well, you can rest easy now.
01:32:48There's an incredibly complex illumination system on the ground that helps the crew navigate
01:32:53the airplane, and it's not just the red and white lights along the runway.
01:32:58The lights actually start popping up long before the runway, so that the pilots can
01:33:02easily find their way, and different patterns mean different things, which your captain
01:33:07and their co-pilot know by heart.
01:33:09Every commercial airplane you've been on has only one wing.
01:33:13The first airplanes were called biplanes because they had two wings, one on the top and the
01:33:18other going through the bottom of the fuselage.
01:33:21They were connected with struts and wires, which made kind of a box, that basically allowed
01:33:26the craft not to fall apart in the air.
01:33:29How thoughtful!
01:33:30It was necessary at lower speeds than earlier planes could only muster, but as the engines
01:33:35increased in power, the second wing became redundant and repetitive.
01:33:41The single wing still serves as a support for the whole structure, though.
01:33:46Going 100 mph on an interstate makes you feel the drive and excitement of speed.
01:33:52Flying at nearly 600 mph makes you drowsy at best.
01:33:56This is because you don't feel the actual speed of anything.
01:33:59You can only see how fast you're moving relative to other objects.
01:34:03The closer, the faster.
01:34:05In a car, everything's close to you, so you see trees, people, houses, witches, porcupines,
01:34:11and other cars zapping past you.
01:34:13On board a plane, everything's so far away that it seems to go at a snail's pace.
01:34:20Take a good look at your smartphone.
01:34:22It might never have occurred to you, but its rectangular shape is no accident.
01:34:27And it's actually what you want it to be.
01:34:30Rectangle is the most convenient shape for a screen.
01:34:33It has an orientation, so you can flip your phone all you want and it will adapt.
01:34:38Imagine that with, say, a round-shaped display, you'd have to always turn it in your hands
01:34:44until the top is where it belongs.
01:34:46Next, it fits into your pocket nice and cozy.
01:34:50The pocket is deeper than it is wide, so a phone longer than it is broad will sit there
01:34:56perfectly.
01:34:57A square or circular phone will be more of an inconvenience.
01:35:01Then again, a rectangle is much easier to handle.
01:35:04It fits in your palm, and it feels better than a circle or a square.
01:35:08And finally, we're used to having rectangular things all around us – pictures, sheets
01:35:14of paper, books, Spongebob, photographs.
01:35:17Having round-shaped screens would've been just weird.
01:35:21Still, there have been attempts to create circular and square smartphones, but as you
01:35:26can guess, they didn't catch on.
01:35:29Taking photos in the dark with a flash, you must've noticed your smartphone flashes
01:35:34several times before making the actual shot.
01:35:37Remember those horrid red eyes in old photographs made on film or digital cameras?
01:35:43That happened exactly because the camera flashed only once.
01:35:47In the dark, the pupils of your eyes become larger, trying to catch more light to see
01:35:52better.
01:35:53And when they reflect the camera's flash, the red-eye effect appears.
01:35:57With smartphones, the first short flash makes the pupils contract from bright light, and
01:36:02only then the device takes a shot, and you don't resemble a horror movie creature anymore.
01:36:09There are two main reasons why there are no public bathrooms in the subway – safety
01:36:14and financing.
01:36:15They're ridiculously expensive to maintain, so I guess we won't be seeing many of such
01:36:21cabins where they weren't before.
01:36:24The second reason is security concern, since there can be no cameras installed in the bathroom,
01:36:29and any kind of suspicious activity would go unnoticed.
01:36:34It seems only natural that a vehicle that carries so much more people than a car should
01:36:39have seatbelts.
01:36:40But buses have none, even school ones.
01:36:43In fact, it has to do with several things at once.
01:36:47First of all, in case of emergency, passengers need to get off a bus as fast as possible.
01:36:52With seatbelts on, they'll waste precious time on unbuckling them.
01:36:57Secondly, a bus is a big and heavy vehicle.
01:37:00On the road, there are not many other members of the traffic that weigh more than a public
01:37:04bus.
01:37:05So, in case of a collision, a bus would stop much slower than a car.
01:37:10And even though its passengers will certainly feel the impact, they normally won't get
01:37:14hurt as much.
01:37:15That's also the reason why passengers are allowed to ride standing too.
01:37:20If your hotel has card keys with magnetic strips, make sure you put your card key apart
01:37:26from your cell phone and wallet.
01:37:28The problem is that card keys are rewritten quite a lot, and they're designed for that
01:37:33process to be quick and easy.
01:37:35So, a fairly strong magnet like the one in your cell phone can erase your key card, and
01:37:41you won't be able to get back inside your room.
01:37:43The hotel will surely provide you with a new card, but that's still inconvenient.
01:37:49If you're struggling to get your taco shells to stay in place, use a muffin tray.
01:37:54Flip the tray upside down, spray it with oil, and place your tortillas in the gap.
01:38:00Cook them for around 10 minutes at 700°F for the perfect crispy taco shell.
01:38:05Now I'm getting hungry, you?
01:38:08Looking for a lost earring or pin on the floor?
01:38:11Place a stocking over the end of your vacuum and move it over the floor.
01:38:16The small object will get picked up without getting vacuumed.
01:38:19It helps to turn the vacuum on while attempting this.
01:38:23Candle wax that's been spilled on furniture can be removed with ice cubes.
01:38:28Rather than ruining the finish by trying to scrape it off, fill a plastic bag with ice
01:38:33and let it sit on the wax for a few minutes.
01:38:36The wax will then cool and harden, making it much easier to pick off.
01:38:41Crayon marks on the walls are a parent's worst nightmare, but you can use a hairdryer
01:38:46to get them off.
01:38:47Heat the marks for just a few seconds to soften the wax, and then you should be able to just
01:38:53wipe it away.
01:38:54You can use hair conditioner to make that new wool sweater less itchy.
01:38:59Just soak it in lukewarm water with a couple of tablespoons of conditioner and leave it
01:39:03for 15 minutes.
01:39:05Then just dry it, and your sweater will be much softer.
01:39:09That layer of bubbles that forms when you add bubble bath to your tub isn't just for
01:39:13fun.
01:39:14The bubbly layer also acts as insulation and keeps your bath warmer for longer.
01:39:20Next time you're getting ready for work, take a closer look at your go-to shirt.
01:39:25Every buttonhole is stitched vertically.
01:39:28But check out the very last hole – it's stitched horizontally, right?
01:39:32This is because the bottom part of your shirt endures the most stress from pulling as it's
01:39:38where your hips are.
01:39:39So that horizontal buttonhole isn't a mistake – it's put there to stop your shirt ripping
01:39:44as your hips move.
01:39:46Hey, those hips don't lie!
01:39:49That random diamond on your backpack is called a lash tab or pig snap.
01:39:53It's there so you can thread cords through the holes to carry extra gear – perfect
01:39:58for camping or long hikes.
01:40:01If you put your Chinese takeout on a plate when it arrives, you're doing more work
01:40:05than you should.
01:40:07Just like the paper condiment pots in fast-food restaurants, your cardboard Chinese takeout
01:40:12box can be unfolded to create the perfect-sized plate for your food.
01:40:17That hole in your hollow lollipop stick isn't to prevent choking should it ever be swallowed
01:40:22– it's actually there to keep the candy in place.
01:40:26Excess candy flows into the hollow tube and the hole, which, when it hardens, keeps the
01:40:31pop in place.
01:40:32If it was a smooth stick, the candy would slide off easily.
01:40:36Some skyscrapers have hollow floors that contain nothing but an elevator and some complex
01:40:41machinery.
01:40:42They're called technical floors, and developers say they're there to maintain the building's
01:40:47proper functioning.
01:40:49But it's also a way to get around height limits.
01:40:52Some skyscrapers are given a limit to the number of floors they can have.
01:40:56Because the technical floors are non-residential, they add to the height of the building and
01:41:01make it look more impressive without increasing the number of floors and breaking the building
01:41:05contract.
01:41:07These floors can also help to prevent the spread of fires.
01:41:11If you look closely at an elevator door, you'll notice a tiny hole.
01:41:15This is actually a keyhole used for emergencies or for routine maintenance checks.
01:41:20If you get stuck in an elevator, the technician will be able to get you out of there by using
01:41:25their master key.
01:41:28Salt isn't just used for cooking – it can get rid of tough smells!
01:41:31Like this!
01:41:32Phew!
01:41:33Applying salt on your fingertips after chopping garlic should remove the smell.
01:41:38It also works on shoes.
01:41:40Toasters have a secret slide in the bottom that can be removed so you can clean out all
01:41:45those annoying breadcrumbs.
01:41:47Now take a look at your laptop keyboard.
01:41:50There are bumps on the F and J keys, but nowhere else.
01:41:54When your fingers are in the optimal typing position, your index finger should rest on
01:41:58these two keys.
01:42:00The bumps have been added so that you can correctly position your hands for typing without
01:42:04looking at your keyboard.
01:42:06Washing your clothes on a low heat or even better, a cold wash, will make them last twice
01:42:11as long.
01:42:13Drying them on a line, if possible, will also make the material last longer than if you
01:42:17used a dryer.
01:42:19The less you wash them, the less they'll fade and shrink over time.
01:42:23It'll also save you on your energy bills.
01:42:26Blank pages in the books aren't actually made for the author's signature.
01:42:30It's all about the manufacturing process.
01:42:33Books are printed on large sheets, so one sheet can fit 4 printed pages.
01:42:38If a book has an odd quantity of printed pages, chances are you'll get a blank one for notes.
01:42:44Tree cart loops have more functions than you think.
01:42:47You don't want to put your fancy white jacket in a cart next to carrots and Coke.
01:42:52This little hook-like thingy helps organize all the stuff in your cart better, so you
01:42:57can enjoy your shopping trip.
01:42:59Works for me!
01:43:01A good doorknob is one made of brass, bronze, or some copper alloys.
01:43:06These metals have an anti-germ effect.
01:43:10Bacteria spread way slower on them.
01:43:11They also get rid of germs pretty fast, within a couple of hours.
01:43:16There's only one way you can store your peanut butter right.
01:43:19If you place it the regular way, it may get a bit solid before long.
01:43:24The trick is to store it upside down, so the oils don't stay on the bottom all the time
01:43:29and distribute evenly.
01:43:32My dog loves peanut butter.
01:43:34How about yours?
01:43:36Whatever coffee shop you go to, all the disposable cups look exactly the same, only the logo
01:43:42changes.
01:43:43The secret here is the special shape that lets you enjoy your drink easily.
01:43:47The top is always wider, which allows it to accommodate your nose while you're drinking,
01:43:53and the bottom is always narrower, so that anyone can hold it easier, even if the hand
01:43:58is quite small.
01:43:59This width difference also allows the cups to stack.
01:44:03Spoiled milk emits gases, like most foods when they go bad.
01:44:08Poor me!
01:44:09A classic plastic milk jug has a concave shape on one side, so when the gases expand inside
01:44:15the jug, it expands too, and the concave shape curves out.
01:44:20Also, if you want to save some milk for later and freeze it, the jug will expand when the
01:44:26milk gets solid as well, occupying more space in a jug.
01:44:30Almost all measuring tapes have a metal tip with a small slot on the end.
01:44:35You can use this slot to hang the tape on a nail or a screw to make measurements without
01:44:40anyone's help.
01:44:42Sometimes this tip has a row of sharp points along the edge on one side.
01:44:46It comes in handy when you want to leave a mark without using a pencil.
01:44:50If you've ever tried a Nintendo cartridge to taste, you'll confirm that they taste
01:44:56revolting, leaving a sour, bitterish aftertaste in your mouth.
01:45:00We tried to tell you!
01:45:02They're covered with denatonium benzoate, one of the most disgusting flavors now.
01:45:07Not normally seen in ice cream stores either.
01:45:10Actually, this taste has a righteous function.
01:45:13It prevents people from swallowing those cartridges.
01:45:16Rough edges on the dimes are just about design.
01:45:20The coins used to be made of precious metals to show their real value.
01:45:24People would shave off the edges, spending the shaven coins with the same value and melt
01:45:29the edges to new coins.
01:45:31To avoid it, minters added that pattern so people could tell if someone cut that coin
01:45:36before.
01:45:37A triple handle on a jerry can is there to make it easier for two people to carry it
01:45:42and distribute the fuel evenly.
01:45:45Lemons get juicier if you warm them up a little bit in the microwave.
01:45:49The heat softens the frozen membranes, so the juice can flow out freely.
01:45:54The result?
01:45:55More lemonade for you!
01:45:57The expiration date on mineral water isn't about water going bad.
01:46:02Actually, no water can spoil, but the bottle can.
01:46:06Over time, it starts leaking some chemicals that aren't quite safe.
01:46:10Ok, here's a science project to try.
01:46:14Tonic water can be fluorescent in UV black light.
01:46:18It contains quinine, which makes it both bitter and glowing.
01:46:23The color of plates and cups can affect your food perception.
01:46:26A group of 57 volunteers drank hot chocolate out of different cups, but most people claimed
01:46:32the orange cup hot chocolate was the best.
01:46:35Red color plates are cool for those on a diet.
01:46:38It looks alarming, so you end up eating less.
01:46:42Ok, I'm gonna go do the tonic water black light thing.
01:46:46Bye!
01:46:47If you've ever gotten bored while waiting in a car like I have, you might've played
01:46:51around with a headrest.
01:46:53Yep, you can pull them off, and they'll come right off relatively easily.
01:46:57It seems useless at first, but that's something you'll want to do if you're ever trapped
01:47:02in a car and need to break a window to get out, like I do.
01:47:06Even a box of aluminum foil has its secret.
01:47:09On the side of the box, you can see a small tab you can push in.
01:47:13So simple, but that's what actually holds the roll of foil in place.
01:47:18This tab makes it way easier to unroll a sheet and tear it off without any frustration.
01:47:25Ever wondered why gripping a certain tool, handle, or even a pen kind of feels more secure
01:47:30when it's coated with a rubbery material?
01:47:33The keratin of the outer layer of the human skin is rough and stiff at a small scale.
01:47:38So let's say you have a polished metal or glass which is stiff but also a smooth and
01:47:43impenetrable surface.
01:47:45When you encounter that, the actual contact area is small, as is the friction at the beginning.
01:47:51Your sweat pores secrete moisture, which is why the keratin gets hydrated and becomes
01:47:56softer.
01:47:57Because of that, it requires many seconds for the contact area to increase to the same
01:48:01value it reaches almost right away with some soft materials like rubber.
01:48:06This mechanism might be used by our tactile senses when we want to identify materials.
01:48:13The pom-poms on beanies and other hats have their purpose, and it's not just to look
01:48:18cute and fluffy.
01:48:19Well, at least they did have a purpose.
01:48:22One of the theories says French sailors used to wear hats with pom-poms so they wouldn't
01:48:26hurt their heads on the ship when the weather got rough.
01:48:29Yep, the ceilings of the ship were really low.
01:48:32When the waves were too big, bang, you could easily hit your head on the ceiling.
01:48:36So the pom-poms came in handy.
01:48:38Now they're just a cute addition to our winter cats.
01:48:42That mysterious drawer under the oven, the one where you keep all your kitchen gear you
01:48:47just don't know where else to put?
01:48:49Well, you used it well in that case, but the drawer was originally designed for keeping
01:48:54your meals warm, at least until you're ready to serve them.
01:48:58And that space under your lower cabinets that protrudes slightly and can't be lifted?
01:49:03This area is also called a toe kick.
01:49:05It's the reason why you can stand closer to the counter while cooking.
01:49:10Also, the doors of the cabinets are off the ground, so they'll swing over your toes.
01:49:16The cabinet under the sink isn't for storage either.
01:49:18Maybe that's where you keep your cleaning products, but its real purpose is to give
01:49:23you access if your sinks leak and you need to do some plumbing work.
01:49:28That weird little hole at the top of a lollipop stick you can see after finishing a candy
01:49:33is not a whistle.
01:49:35It has something to do with the manufacturing process.
01:49:38When pouring hot molten caramel into a mold, some of it will seep into this mysterious
01:49:43hole and harden.
01:49:45This way, the candy will stay on the stick and won't fall off.
01:49:50Keyboard letters aren't just randomly arranged the way they are.
01:49:53The first keyboard ever made belonged to the typewriter.
01:49:57Typists eventually got so good at their job, they started typing too quickly.
01:50:01So the key arms would get cross-wired at some point and stuck.
01:50:05That's why manufacturers had to make the order of keys more random to intentionally
01:50:10slow down typists so they could keep the machine running.
01:50:14Do you like to let those brushes on the side of the escalators in malls polish your shoes?
01:50:19Believe it or not, that's not their main gig.
01:50:22The bristles are there for safety.
01:50:24People used to get their bags and clothes stuck in those escalators when they would
01:50:28stand too close to the sides.
01:50:30These nylon bristles kind of play with people's minds, and they keep their feet away from
01:50:35the escalator's skirt panels and avoid accidents.
01:50:39Most people assume bobby pins have curves for fashion, which is why they mostly place
01:50:44it in their hair with the wavy side up.
01:50:47Those little waves are actually there to catch the underlying bulk of hair and grip the pin
01:50:52into place.
01:50:53So the wavy side should go down.
01:50:56You've probably noticed measuring tapes mostly come with a metal stub that ends with
01:51:01a small slot.
01:51:02If your hands are full of stuff, simply hang the slot on a nail for measurement.
01:51:07If you take a closer look, you'll see the stub is a little bit serrated on one side.
01:51:12This means you can use it to mark the points so you don't even need a pencil.
01:51:17If you spend a lot of time in planes, you've probably noticed that little hole located
01:51:22at the bottom of the window.
01:51:24Nothing to be nervous about, it's what keeps us safe while flying high.
01:51:28It's something called a bleed hole.
01:51:30You can see right there in the middle of the pane of the three window panes that actually
01:51:34protect passengers from the outside pressure.
01:51:37This hole may be tiny, but it takes all that pressure off the outer one.
01:51:42The hole also gradually exposes it to cabin pressure, which helps with fixing pressure
01:51:47imbalances on the windows, if there are any.
01:51:51There's a number 57 staring at you from the middle of the Heinz ketchup bottle forever.
01:51:56According to the company, only 11% of people are aware the number really has nothing to
01:52:01do with the product label.
01:52:03It's actually a sweet spot where you can tap to get the sauce onto the plate.
01:52:08So next time you want some ketchup, there's no need to bang the bottom off.
01:52:12Just hit this spot.
01:52:14Grooves on the bottom of cups are there to make cleaning them in the dishwasher more
01:52:18convenient.
01:52:20When you place your cups upside down, these grooves will allow the water to flow rather
01:52:25than stagnate.
01:52:26This way, the water won't spill onto your feet when you take the cups out.
01:52:30The grooves are there to allow cool air to flow beneath the cup too.
01:52:34They also keep cups from cracking when they heat up after you pour hot beverages in.
01:52:40You probably noticed that little dot next to the camera on an iPhone and probably thought
01:52:45it was a flash.
01:52:46Nope, not a flash, but a microphone in charge of catching sounds when you're using the
01:52:51back camera.
01:52:53Next time you're looking for a quick bite and decide for fries at McDonald's, check
01:52:58that bendable flap near the top of the box.
01:53:01Some like to bend it towards the fries.
01:53:03That way, you can cover your fries up and keep them warm.
01:53:06But if you're not that patient, you can flip the flap backward and basically turn
01:53:11it into a makeshift plate for your fries.
01:53:14Just bend it down firmly enough – you don't want it to spring back up and spread the sauce
01:53:18all over you.
01:53:19Take it from me, it's messy.
01:53:22In the 1970s, people didn't want toothpaste just to keep their mouths healthy, but also
01:53:27to freshen their breath.
01:53:29Aquafresh decided to answer that call, so they added a blue stripe to their product.
01:53:34Since consumers started paying more attention to their teeth and gums, the company added
01:53:38a third red stripe to their paste.
01:53:41The paste now has three functions – freshening, cleaning, and plaque control.
01:53:45And yes, solid white toothpaste can offer the same benefits, but brands continue to
01:53:50add stripes to their paste anyway.
01:53:53Speaking of toothpaste, do you know those colors on the bottom of tubes?
01:53:57The colors don't mean anything in particular – they're there to help in the manufacturing
01:54:02by telling light sensors where the end of the tube is.
01:54:05Thanks to it, the machine can cut and seal the tube properly.
01:54:10Hand sanitizers are commonplace nowadays, and you can apply them in many other ways
01:54:14besides just cleaning your hands.
01:54:17It also works great when you want to remove stains from your clothes.
01:54:21Sanitizer breaks up oily, greasy spillages and does a great job as a degreaser.
01:54:26You can even use it as a deodorant if you get caught out on a hot day!
01:54:31The bottom of the bottle mostly has a small odd-shaped notch.
01:54:35It's called a deco-lug, and without it, your bottle wouldn't look the way it does
01:54:40now.
01:54:41Such bottles are mass-produced in factories using machinery, and each of them looks the
01:54:45same.
01:54:46Since plastic bottles mostly needed artwork on them, manufacturers wanted to make sure
01:54:51the artwork always gets printed in the same position for each bottle.
01:54:55So they invented the deco-lug, short for decorating-lug.
01:54:59It actually holds each bottle at the same orientation in the machine that applies the
01:55:03artwork.
01:55:05Without it, workers would have to watch the whole process and adjust the bottles by hand.
01:55:13So grab your phone.
01:55:14Good, now turn it around.
01:55:16You see that little dot between the camera and the flash?
01:55:19That's a tiny microphone.
01:55:21Bet that's something you didn't know.
01:55:23What's it doing there?
01:55:25Well, when you're on a phone call, this little guy is busy at work, reducing the amount
01:55:29of background noise other people hear when you talk.
01:55:32That's right, if it wasn't for this, calls wouldn't be as nearly as crisp as they are
01:55:38now.
01:55:39You're lost in the woods, and you're rushing to get back to camp.
01:55:44You suddenly remember you've got something that can help.
01:55:47You grab one of your chest straps from your backpack and whistle on it.
01:55:51Yep, that's right.
01:55:53A lot of bags have this feature in them, especially the ones made for the outdoors.
01:55:58It isn't long before you hear the call of one of your friends, and you follow them back
01:56:02to the warm campfire, saved by this cool bit of design.
01:56:08If you're a curious person, you might have wondered what that little pocket in your jeans
01:56:12is doing there.
01:56:13You know, the one that's inside the bigger pocket?
01:56:17People often use it to store coins and bills, but it's not meant for that.
01:56:21It's actually designed to store your pocket watch safely.
01:56:26Maybe that's where the name pocket watch comes from?
01:56:30You finally arrive home after a long day's work.
01:56:34You understandably don't feel like cooking, so you sit on the couch and watch a bit of
01:56:38TV and order some takeout.
01:56:41How about Chinese?
01:56:42Ah, perfect.
01:56:43There's the doorbell.
01:56:45That has to be your food!
01:56:47It smells delicious!
01:56:48Wait, before you grab the plates, do this instead.
01:56:52Open your Chinese food container on the table.
01:56:55It becomes the perfect plate, and it's cardboard.
01:56:59Which means no cleaning either!
01:57:02That can of soda you got with your food has a cool feature too.
01:57:06Look at the tiny metal tab there, the one you use to open the can.
01:57:10Guess what?
01:57:11You can fit your straw in there!
01:57:13In fact, that's exactly what they're made for!
01:57:15Go ahead, try it for yourself!
01:57:19If you're not at your computer, take a look at your keyboard right now.
01:57:23If you're not, that's okay.
01:57:24Here's one on the screen.
01:57:26The keycaps are arranged in what's called the QWERTY layout, named after the first six
01:57:31keycaps below the numbers.
01:57:33As it turns out, it wasn't always this way.
01:57:36They used to be laid out alphabetically, which would make more sense when you think about
01:57:40it.
01:57:41This alphabetical layout fell out of use because long ago, there were things called typewriters.
01:57:47Remember those?
01:57:49You pressed down a key, and a type bar would fly out, hitting an inked ribbon and stamping
01:57:54a letter on the piece of paper.
01:57:56Eventually, typists got good at this and typed faster.
01:58:00Too fast.
01:58:01The type bars would eventually get caught in a log jam with each other, ruining the
01:58:05flow.
01:58:06To fix this problem, they made keyboards with randomized keycaps.
01:58:11The new layout actually worked better because it made typing harder, helping to slow typists
01:58:16down and prevent the type bars from getting stuck.
01:58:19Much better!
01:58:20Today, no type bars.
01:58:22No typewriters, mostly.
01:58:24People are still fast nowadays, but you just can't help but wonder who was faster, though.
01:58:29Us or them?
01:58:31Keyboards have another hidden feature, too.
01:58:33Have you ever noticed that the F keycap and the J keycap have little bumps on the bottom
01:58:38of them?
01:58:39Turns out, they're there to help people figure out where they are on the keyboard
01:58:43without having to take their eyes off the screen.
01:58:47Grabbing a takeaway cup of coffee at your favorite cafe might be just what you need
01:58:51to fully wake up in the mornings.
01:58:54When you get back home or to work, though, you might be afraid to stain your desk when
01:58:58you put the steaming hot coffee down.
01:59:01Worry not, your plastic lid isn't only good for keeping your coffee hot, it also doubles
01:59:07as a coaster.
01:59:08In fact, they're the perfect size to hold a cup.
01:59:11Try it for yourself!
01:59:13This one's gonna come in handy if you're a home cook.
01:59:16If you're like me, you might have a bit of trouble deciding how much pasta you need
01:59:21for just one serving.
01:59:22Well, if you've got a pasta scoop, grab that.
01:59:26Most people don't know what the little hole in the middle is for and assume it's supposed
01:59:30to help with water drainage or something.
01:59:33It turns out that it helps you measure out a perfect serving.
01:59:37Just see how much dry spaghetti you can fit in the hole and use that as one portion.
01:59:44Out of the store buying coat hangers, you might notice that the plastic ones feel cheaper
01:59:48than the wooden ones.
01:59:50There's a good reason for this – wooden hangers are made out of cedar wood.
01:59:54The big difference between the two is that the wooden ones repel bugs and moths.
02:00:01They're stronger and last longer too, perfect for things that might stay in your closet
02:00:05for a long time.
02:00:08When you brush your teeth, you might've noticed that your toothbrush has blue bristles.
02:00:12They're not just there for show.
02:00:14In fact, they're there to tell you when it might be time to switch toothbrushes.
02:00:19These bristles lose their strength and color when the brush has been worn down, letting
02:00:23you know that it's time to get rid of it.
02:00:28Microwaves often look a bit like mini-TVs, especially ones where you can clearly see
02:00:32the black film around them.
02:00:35This is actually a really important feature that's used to keep the radiation from slipping
02:00:39away.
02:00:40They're called Faraday cages, if you want to get technical.
02:00:44This is why you can stand next to a microwave without melting into a puddle.
02:00:49That's not to say you should stand in front of the microwave and watch your food heat
02:00:53up, but at least you know you won't grow an extra ear or something.
02:00:57Okay, not really.
02:00:59Some ovens have a drawer under them.
02:01:02It's tempting to use this to store random junk you don't use often, but there's a better
02:01:06use for it.
02:01:07Instead, this should be used to help keep the food that's waiting to be served hot.
02:01:12You can take it out of the oven and store it right in this drawer, keeping your oven
02:01:16free for you to carry on cooking.
02:01:19Now, you're on a plane looking around trying to pass the time before takeoff.
02:01:24When you examine the window, you notice this has a little, very tiny hole on its bottom.
02:01:30Don't worry, it's not broken.
02:01:32It's there to relieve the pressure that builds up over time as the plane goes up and down.
02:01:37It also lets the air flow through it.
02:01:40Now, raise your hand if you've ever ridden on an escalator and scrubbed your shoes on
02:01:44its bristles.
02:01:45Hey, I'm guilty of doing that.
02:01:47Maybe more than I should.
02:01:49It's not there to clean your shoes, though.
02:01:51It's an important safety measure.
02:01:53It stops your shoelaces, clothing, and other stuff from getting stuck in there, avoiding
02:01:57a nasty scene when you go to get off.
02:02:02Sometimes a piece of fabric comes with your new clothing.
02:02:05It usually comes along with the extra buttons in a little plastic bag.
02:02:09You might think it's just a piece of fabric to use for future patching, in case you rip
02:02:13it.
02:02:14But that isn't its purpose at all.
02:02:16It's actually supposed to be put in the washing machine to test how it reacts to various
02:02:21washings.
02:02:22Now, you don't have to worry about shrinking your new, expensive coat because you know
02:02:26how it'll react to the wash.
02:02:29Bubbles!
02:02:30Who doesn't love bubbles?
02:02:31Most people have fond memories with bubble blowers as a kid.
02:02:35But as adults, the closest thing we can get to recapturing that feeling is with bubble
02:02:39baths.
02:02:41After a hard day at work, there's nothing better than dipping into a nice warm bubble
02:02:45bath.
02:02:46Right, guys?
02:02:47And the bubbles do more than just clean you.
02:02:49If they're high-quality bubbles, they'll serve as a heat insulator.
02:02:53So they make sure that your bath stays warm for longer.
02:02:59Boxes of chocolate sometimes have these mysterious holes in them.
02:03:02When I'm eating a box, or two, I usually ignore them and take out the chocolate by
02:03:07pressing the bottom of the plastic.
02:03:10But it turns out that I've been doing it wrong the whole time.
02:03:14If you press one of the holes, the chocolate comes right out.
02:03:17I'm certainly going to start doing this from now on.
02:03:22Here's another one from the kitchen.
02:03:24The handle on a pot will often have a hole in it.
02:03:27Most people use this to hang them on a nail on the wall as an easy storage method.
02:03:32The hole has another use too.
02:03:35When you're cooking, you can use this handle to hold your wooden spoon or whatever else
02:03:39you might be cooking with.
02:03:41This makes sure you don't make a mess when you put it down.
02:03:45Glass bottles usually come with a cap in them.
02:03:48Well, duh.
02:03:49Otherwise, the liquid would just spill.
02:03:52In this cap, there's a plastic liner that seemingly has no purpose, right?
02:03:57Wrong.
02:03:58It's a seal.
02:04:00No, not a seal.
02:04:02A seal.
02:04:03It's the kind that helps keep your drink fizzy.
02:04:06Ah, just the refreshment I needed.
02:04:09A lot of doorknobs are made out of brass, and it's not by chance.
02:04:12They're made out of this specific material because it's bacteria's worst enemy.
02:04:17That's right, it destroys them.
02:04:20Perfect for those who want to keep a clean house and avoid germs.
02:04:23Hey, you want a fish?
02:04:28New iPhone models with large screens have a convenient option called Reachability.
02:04:34Thanks to this function, you don't have to struggle to reach the top of the screen.
02:04:37This feature can be found in the phone's accessibility settings.
02:04:41It allows you to lower your screen down.
02:04:44The rumble strips on the side of the road are there to wake up sleepy drivers who doze
02:04:48off behind the wheel.
02:04:49When your tires drift off onto these strips, the noise and vibration work like an alarm
02:04:54clock.
02:04:55Most kitchen shears have metal plier-like teeth in the middle.
02:04:59They allow you to use the device for multiple purposes.
02:05:02They're placed between the handle grips for you to crack nuts, crab shells, and whatnot.
02:05:06You can also open jars and bottles with their help.
02:05:09Some people even use these teeth to remove stems from herbs.
02:05:13If your audio jack has three rings, it means your device can produce stereo sound, and
02:05:18your earphones have the microphone function.
02:05:21The black grating on a microwave oven door is called a Faraday shield.
02:05:25It stops microwaves from getting away.
02:05:27If they do, your food won't cook properly.
02:05:30The digits on an egg can tell you a lot about the product.
02:05:34In many countries, there's a special labeling system.
02:05:37The first number indicates the method of production.
02:05:39The following two-letter code stands for the country where the egg was produced.
02:05:43And then you can find a registration number.
02:05:46It indicates the laying hen establishment.
02:05:48The first number in this code can vary from zero to three.
02:05:52Zero means it's an organic egg.
02:05:54One, it's a free-range egg, which means it was produced by a hen that was allowed
02:05:58to wander around outdoors.
02:06:00Two stands for an egg produced in a deep litter indoor housing.
02:06:04Three, you're about to buy a cage farming egg.
02:06:08A black band that runs along the edges of your windshield is called the frit.
02:06:12It's a baked-in ceramic paint that starts as solid black bands near the edge of the
02:06:16windshield.
02:06:18Then it dissolves into smaller dots.
02:06:20The frit makes the glass rougher, and the adhesive sticks to it better.
02:06:24The frit protects the urethane sealant.
02:06:26It's the substance that fixes the glass to the frame.
02:06:29It also prevents the sun's ultraviolet rays from melting the adhesive.
02:06:33As for the black dots, they help distribute the temperature in the car more evenly.
02:06:38They're aesthetically pleasing too.
02:06:40Without them, the contrast between the glass and the dark band would be too obvious.
02:06:45If you see a pair of jeans with an extra loop, those are special jeans for cyclists.
02:06:51They're likely to belong to the commuter clothing line, and the loop's main purpose
02:06:55is to hold your bike lock.
02:06:57Many zipper sliders have outer rings, especially if such sliders are supposed to be used together.
02:07:03These rings are added so that you can connect the sliders with the lock and keep pickpockets
02:07:07away.
02:07:09Keyboards come with little legs.
02:07:11They were designed for you to be able to tilt your keyboard.
02:07:14This way, you can actually see which keys you're hitting.
02:07:17At the same time, a flat keyboard doesn't make your wrists so tired, and people who
02:07:21can type without looking at the keyboard don't need those legs whatsoever.
02:07:25An olive spoon is usually made of stainless steel and has a small hole cut in its bowl-shaped
02:07:31head.
02:07:32The main purpose of this utensil is to lift olives, cherries, pickled garlic, and other
02:07:37products from liquid-filled jars, cans, or bowls.
02:07:40The hole in the middle allows you to drain the liquid gathering in the spoon fast and
02:07:44easily.
02:07:45What'll they think of next?
02:07:47Donuts are shaped like rings because, otherwise, they get overdone at the edges and remain
02:07:52uncooked and gooey inside.
02:07:54Make a hole in the center, and both the outsides and the insides will be cooked at the same
02:07:59time.
02:08:00Round-shaped donuts, with no holes, are usually filled with custard, cream, or jelly.
02:08:06Such donuts don't have any corners, which means there are fewer weak spots for the filling
02:08:10to spurt out from.
02:08:12If you grab a full juice box a bit too firmly, you can get sticky liquid all over the place.
02:08:18To avoid such situations, flip up the tabs on the sides of the juice box.
02:08:22You can use them to hold your drink.
02:08:25Some cars have a tiny coffee cup sign on the dashboard.
02:08:27It's the vehicle's anti-drowsiness mechanism.
02:08:31Some manufacturers equip their cars with a drowsiness detection system.
02:08:35It analyzes the speed, wheel angle, and lane deviations, and figures out if it's time
02:08:40for the driver to take a break.
02:08:42If it is, the vehicle makes several audio signals, and the coffee cup sign starts to
02:08:46flash.
02:08:48Produce stickers on fruit and veggies you get at the supermarket are full of information.
02:08:53If there's a 4-digit code on the sticker, the product was grown conventionally.
02:08:57In most cases, it also means that pesticides were used in the process.
02:09:02If the product is organic, its sticker has 5 digits, and the first one is 9.
02:09:07Genetically modified products also have a 5-digit code, but the first number is 8.
02:09:13Sugar used to be sold in sugar loaves.
02:09:16Those were tall, hard cones.
02:09:18At those times, to get sugar ready for tea, people had to use special hammers to break
02:09:23a loaf apart first.
02:09:25After that, they cut the sugar into smaller and more nicely shaped lumps.
02:09:29Maybe in the middle of the 19th century, people invented the first press that cut sugar
02:09:34into cubes.
02:09:35This way, the product was easier to store and transport.
02:09:38A little hole in the end of your wrench can provide your screwdriver with some extra torque.
02:09:43Just slide the end with the hole over the screwdriver.
02:09:46You can also use this method when the angle is awkward.
02:09:49While driving, when it's already dark, you might get blinded by the headlights of the
02:09:53car moving behind yours.
02:09:56If you have a manual rear-view mirror, find a tab at the bottom and flip it.
02:10:00The mirror has a reflective material behind its glass.
02:10:03By flipping the tab, you change the angle of this material, dimming the lights in the
02:10:07mirror.
02:10:09Most ice cream scoopers come in different colors.
02:10:11It has nothing to do with aesthetics.
02:10:14The color indicates the size of the scoop.
02:10:16This way, you can easily figure out how many scoops you'll need to fill 32 oz.
02:10:21Wow, a 32-ounce sundae, sign me up!
02:10:25Some caps on small tubes are hollow on top and have a little spike inside.
02:10:30Its purpose is to break the foil sticker sealing the tube.
02:10:33The neck fits right in this hole, and the spike is designed to break the seal.
02:10:37This way, you don't need to tear the tiny foil seal off with your fingers.
02:10:42The letter R in a circle on the product's packaging means that the trademark is officially
02:10:47registered.
02:10:48Once it's done, the trademark's owner has the right to place this letter on all their
02:10:52products.
02:10:53You can also sue anyone who tries to use their trademark.
02:10:57A gas pump usually has a small metal latch or hook on its handle.
02:11:01That's a trigger lock.
02:11:02You can use it to lock the handle in the open position.
02:11:05Then the gas will keep pumping even if you walk away.
02:11:10Coins used to be shaped randomly or have no shape whatsoever in the past.
02:11:13Dishonest people used it to their advantage.
02:11:16They stole valuable metals the coins were made of by chipping their corners off.
02:11:21It was illegal, and to prevent this kind of fraud, round coins were invented.
02:11:25After that, it became easy to instantly notice when a coin had been fiddled with.
02:11:31Those two holes in a lollipop stick are there to hold the candy in place.
02:11:35When the stick is dipped in hot liquid syrup, it flows into the holes and solidifies.
02:11:40Now your sweet is there to stay.
02:11:42Fabric squares that come with clothes are for you to try out your cleaning products
02:11:46on them first.
02:11:48This way, you won't ruin the entire item once you decide to wash it.
02:11:52The holes in the bottoms of earphones allow air to circulate up and through the speakers.
02:11:57It helps to increase low frequencies, making the bass sound deeper.
02:12:01The sound quality also becomes much better.
02:12:03Don't I sound better?
02:12:05Thank you!
02:12:06You can adjust your stapler so that it staples documents together only temporarily.
02:12:10It's done by rotating the crimp area.
02:12:13Most staplers have two options for stapling.
02:12:16One is standard, but the other side bends staples away from the center.
02:12:20Later, when you don't need them anymore, you can easily remove them by hand.
02:12:25If you store peanut butter jars upside down, the oil will move to the bottom, and all the
02:12:30solids will be on top.
02:12:31Hey, don't laugh!
02:12:33That matters to some people.
02:12:34You don't want to get caught with your peanut butter down.
02:12:39The cylinder on the end of a cable is sitting there, useless as it might seem.
02:12:44In fact, this is a ferrite bead that assists with many electrical wires to reduce electromagnetic
02:12:51interference.
02:12:53Electrical wires act like unintentional antennas, broadcasting the EMI.
02:12:59There's a reason why the spinning wheel inside the microwave is circular.
02:13:03A circular object will evenly distribute the heat as opposed to a rectangular and square
02:13:08one.
02:13:10When you place containers of these shapes inside, the energy is focused on the corners
02:13:15rather than spread evenly like in a round container.
02:13:20The temperature gauge on a toaster is commonly used to determine how crisp you like your
02:13:24toast, but the other, more specific use for the gauge was for the different types of bread.
02:13:31White and sweet types of bread heat up much faster as opposed to heavier brown and rye
02:13:36ones.
02:13:37The older bread is, the more time it will need in a toaster to ensure the golden brown
02:13:42results you're looking for.
02:13:45Most ovens give you the option of leaving the door ajar when broiling a dish inside.
02:13:51You probably think the goal here is to help cool down the oven after use.
02:13:56In reality, its purpose is to focus on cooking the top of the dish and to ensure a crusty
02:14:01layer.
02:14:03Controlling the buildup of heat and steam by releasing it through the slightly ajar
02:14:07door gives you the desired result without cooking the entire dish to a crispy end.
02:14:14You probably noticed that your dishwasher has specific areas for different types of
02:14:19cutleries and dishware, but all the dishware pieces should be facing towards the center
02:14:25and not all in one direction.
02:14:27What types of foods were on the plates will also determine where they should be located
02:14:32in the racks.
02:14:34As the middle of the machine gets the strongest spray, carb-based stains from tomatoes and
02:14:39potatoes should be placed there.
02:14:41The detergent is more focused on the outside during the clean, creating a waterfall-like
02:14:46cleanse.
02:14:47That's why protein-based stains, like from eggs for example, should be stacked there.
02:14:55Ceiling fans push cool air down on a hot day, circulating the room, but they can serve you
02:15:01during the winter just as effectively if you flick that switch on the side or use the pulley.
02:15:07So if you want to save some money on heating and try to quickly warm up your room on a
02:15:11cold day, turn the fan on, it will push the air up and spread the warm air around, more
02:15:17effectively warming the room up.
02:15:19Do you still use sticky notes instead of those fancy new apps on all possible gadgets?
02:15:26Welcome to the club.
02:15:27Regardless of what you use them for, they can annoyingly curl up.
02:15:31If you've had this issue, it's because you've peeled them from the bottom upwards.
02:15:36Doing it this way causes the curling.
02:15:38Peeling them from the side will ensure they remain flat, ready to remind you of your daily
02:15:43tasks.
02:15:44Did you know that can openers weren't invented until 50 years after preservation cans had
02:15:50been readily available?
02:15:52So how would it be possible to open a can?
02:15:56Here are a couple of alternative methods just in case you've misplaced your trusty opener.
02:16:01All you need is a metal spoon.
02:16:03Set the can down on the counter, hold onto it firmly and grasp the head of the spoon
02:16:08tightly.
02:16:09Apply pressure and vigorously rub the edge of the can's top over a small area.
02:16:15It takes time, but as you continuously rub, a small indentation soon opens a hole.
02:16:21Once the hole is wide enough for the spoon's tip, pry the lid upwards and keep going along
02:16:25the edges until you can finally access the hard-earned meal within.
02:16:30Most toilets rely on water pressure and gravity to function, so a power outage will not affect
02:16:37them.
02:16:38But if yours does need electricity to function, you must be worried about using it when the
02:16:42power is out.
02:16:44The good news is the power is only used to fill the toilet and not to flush it.
02:16:49As the flushing mechanism will still work, open the toilet tank and pour in a couple
02:16:53of gallons, and you're free to flush away whatever you need to.
02:16:59Blockages in shower drains occur over a long period of time.
02:17:02It's inevitable.
02:17:03We lose 50 to 100 hairs a day, and many of them will endeavor to reside within our shower
02:17:09drains.
02:17:10Hair only forms the foundations of the blockage, and this attracts the build-up of various
02:17:15other things.
02:17:16A great life hack is to use your vacuum cleaner and put the nozzle in the hole once removing
02:17:21the plug.
02:17:22Apply a wet cloth around the nozzle, ensuring air cannot escape.
02:17:26The vacuum will suck up the blockages a lot easier.
02:17:30This will help avoid any extra costs from plumbers, as they themselves use this technique.
02:17:37To make your candles last longer, trim their wicks multiple times and keep them as far
02:17:41away from water and moist as possible.
02:17:44It will guarantee that your candle's wax stays firm and steady, and continues to burn
02:17:50slower for a longer period of time.
02:17:53The empty space between the panes of the oven door is there for a reason.
02:17:58You can stick a brush in there to clean the oven door glass.
02:18:01It's easy to access this space through the bottom of the door, open the lower shelf,
02:18:06then push the brush through the hole.
02:18:10While you're parking in a garage, you might find it difficult to determine how close to
02:18:13it you need to be.
02:18:16Not all cars have sensors ensuring you keep the right distance before the bumper makes
02:18:20an indentation on the wall.
02:18:23Applying a rope with a tennis ball from the ceiling at the right distance will help you
02:18:26learn the best distance to park from the wall.
02:18:30We've all been told to loosen a lock with WD-40 or lubricant.
02:18:34Yes, we all know we should have these around the house.
02:18:38But in case you don't, a great alternative is drawing with a grey lead pencil along the
02:18:42edges of the key and then putting it into the lock.
02:18:46Continue doing this until the keyhole has been adequately lubricated and the key functions
02:18:51smoothly.
02:18:53Pliers are prone to damage when you use them to adjust faucets and shower heads and are
02:18:58also difficult to grip.
02:19:00Take a couple of pieces from the end of an old garden hose and attach them to the jaws
02:19:05of the pliers.
02:19:06You'll find a huge improvement with grip and will avoid wear and tear.
02:19:12You can find a good use for discarded rubber for different things around the house.
02:19:17When fed up with tightening or loosening with a screwdriver, try using a simple rubber band.
02:19:23Place part of it into the screw grip and the screwdriver will have far greater traction.
02:19:29Moving cement blocks isn't safe for your lower back.
02:19:32Even with a wheelbarrow, it can be a risky process to place the cement onto the ground
02:19:37without causing damage.
02:19:39Three simple cylinder pipes can make a world of difference, regardless of the size of the
02:19:43block.
02:19:44Try lifting the edge onto the first pipe with a pry bar, then pushing and maneuvering as
02:19:50you gradually direct the three pipes towards the desired location.
02:19:54Just make sure you're not doing this on a slope.
02:19:58That first strike on a nail can be a great success or will result in a throbbing thumb.
02:20:04A bobby pin is perfectly shaped to hold a nail in place, allowing for your hand to be
02:20:09clear out of harm's way and for you to strike the nail without fear.
02:20:15Use a crayon instead of a pen or pencil while working with a wet saw to ensure the markings
02:20:20are not removed.
02:20:22They will also be easier to see under the murky water.
02:20:27Checking the drains on the roof and determining when they need to be cleaned can take a lot
02:20:32of time.
02:20:34Using duct tape, attach a mirror on the end of a long broom and review whether the drains
02:20:39need to be cleaned.
02:20:41To further assist with your balance as you check on the gutters, attach a pair of old
02:20:45trainers to the end of the ladder.
02:20:47The spread of the shoe and its grip will ensure a further level of safety.
02:20:53Liquid caulk normally comes in huge tubes, so you can never use it all at once.
02:20:58The hardened tips of liquid caulk create blockages.
02:21:02Grab a used cork and drill through it to make a perfect lid, concealing the liquid
02:21:06caulk.
02:21:07Now it's ready to be used again with no blockages.
02:21:12Have you ever wondered what these extra holes at the top of your running shoes are for?
02:21:17They're designed so that you can tie the shoes in multiple different ways.
02:21:21That's useful when you want to compensate for things such as a bad stride or even a
02:21:25damaged toe.
02:21:27Plus, you can change the look of your shoes the way you prefer.
02:21:33Many people use a dust jacket of their book as a bookmarker.
02:21:37No problem with that, it will save your book from bent page corners.
02:21:41But the primary purpose of a dust cover is to keep the book safe from distortions.
02:21:46For instance, if you spill juice or drop some of the food on your book while reading it.
02:21:52The tic-tac dispenser has this little groove on its top, so you can dispense only one tic-tac
02:21:57at a time.
02:21:59Even though, let's be honest here, nobody does that.
02:22:02Most of us just spill a whole bunch at once and then we wiggle all those extra tic-tacs
02:22:06back in.
02:22:09Those rubber bumps you see between the tire treads are there for your safety.
02:22:13The raised edges tell you what the minimum height of your tread is.
02:22:17If the bump and the edges are even, it's time for you to visit the tire shop as soon
02:22:22as possible.
02:22:23But if the bumps are well beneath the level of the edges, you're good to go.
02:22:29What about that black grating on the microwave window?
02:22:32It's something called a Faraday shield.
02:22:35And it's there to prevent microwaves from getting away and turning the entire room into
02:22:39a Faraday cage.
02:22:41If the microwaves escape, your meal won't cook properly either.
02:22:45So yep, the cage is not there to make it difficult for you to see your meal while it's cooking.
02:22:49It's keeping the electromagnetic energy inside.
02:22:55How about a wrench-compatible screwdriver?
02:22:57Cover your screwdriver with the end of your wrench and you can increase its torque.
02:23:02That's why the head of your screwdriver is designed the way it is.
02:23:05When you have odd angles, you can use this strategy.
02:23:10You've probably heard those myths, the blue side of the eraser can erase the pen.
02:23:15False.
02:23:16Its purpose is to erase a pencil.
02:23:18But in case you're writing something on heavier paper, the blue side can remove smudges you
02:23:23see after using the pink eraser too.
02:23:27Have you ever wondered why oranges in supermarkets mostly come in the red mesh bag?
02:23:33It's a trick to make this food look more orange and encourage you to make a purchase.
02:23:37An extra tip, don't throw away the mesh bag.
02:23:40Tie it up so you can have a small pot scrubber to clean your sink, kitchen, appliances and
02:23:46dishes.
02:23:49You can see golf balls don't have a perfectly round shape.
02:23:52Their surface is covered with many little dimples, something golf balls didn't always
02:23:56have.
02:23:57At one point, experienced golfers started noticing how through time, older balls with
02:24:03imperfections such as nicks and bumps could travel further.
02:24:08Such things create turbulence in the air around the golf ball, which eventually reduces drag.
02:24:14So manufacturers started producing balls with dimples so they could go farther and faster.
02:24:22You might have noticed that sometimes there are ridges in toothpick tops.
02:24:26It's more hygienic because when you break that off, you can prop the toothpick up on
02:24:30it and it won't touch anything.
02:24:34Another safety feature you'll find, this time in your car, is a tab on your rearview mirror.
02:24:41With it, you can change the position of the mirror so you don't get blinded if there's
02:24:44a car behind you with its high beams on.
02:24:47So this little tab helps you control the glare of lights coming from behind.
02:24:52This feature showed up in the 1930s, but in the early 1970s, it became a part of standard
02:24:57equipment in most trucks and cars.
02:25:02Do you see that tiny hole on your iPhone right next to the rear-facing camera?
02:25:06It's a microphone, and it's there so your phone can record sound as you turn your camera
02:25:10around.
02:25:14Some cables have a thick cylinder towards the end of the cord.
02:25:18It's called a ferrite core or a choke.
02:25:21It's a magnetic iron oxide that stops high-frequency electromagnetic interference.
02:25:26For example, you know that annoying static noise you get if you bring your phone too
02:25:31close to a speaker?
02:25:33This interrupts your call, which is why cable cords with big cylinders are pretty useful
02:25:37because they prevent these things.
02:25:41Do you know why nearly all luggage bags and backpacks have two zippers?
02:25:46It's way more convenient and easier to open in that way.
02:25:49But not just that, you can also lock these two zippers together to keep the stuff inside
02:25:54your bags safer.
02:25:57You know how toilets at public spots like malls have those big gaps at the bottom?
02:26:03It's primarily for better circulation of air.
02:26:06This type of door also makes it easier to clean the toilet or check if it's occupied
02:26:10if you're standing in line.
02:26:13Other than that, if you get stuck there and the lock gets broken, you still have a way
02:26:17to escape.
02:26:18You can just crawl out.
02:26:22Ever notice those plastic end caps on utility knives?
02:26:26And they also have scales on them, which indicates you may use them multiple times but with sharp
02:26:31edges.
02:26:33You can separate the blades through these plastic end caps, then you can move the slider
02:26:38and bring the sharp blade to the front.
02:26:41If you've ever taken a moment to examine a regular grocery cart, especially their fold-out
02:26:46section, you probably noticed those metal loops jutting out.
02:26:50They're designed to protect the items you carry in your cart.
02:26:54You can use them to hang bags with soft items.
02:26:58You don't want to accidentally squish with heavier products, like bread, or easily breakable
02:27:03things like eggs.
02:27:06Many coffee mugs come with curved notches on their bottom.
02:27:10When you're washing your mugs, put them against the rack at an angle in your dishwasher.
02:27:14This way, the water won't pool in there, so your favorite cup will be completely dry by
02:27:18the time you take it out of the dishwasher.
02:27:22If you're a McFlurry fan, you've probably noticed there's a square hole in the handle
02:27:27of the spoon.
02:27:28It's there so you can attach it to the special machine that mixes the ice cream and your
02:27:32favorite toppings together.
02:27:35The machine has a bar that slips into this square-shaped spoon and then thoroughly stirs
02:27:39it.
02:27:41And you get the spoon so they can minimize the mess during the process.
02:27:45Quite neat, wouldn't you say?
02:27:48A regular milk jug has a dent on one side.
02:27:52Some might see it as a random design decision, but a dent has several purposes.
02:27:57One of them is to get bigger if there's a gas buildup.
02:28:01This happens when your milk is spoiled, so you don't even have to try to check this out.
02:28:06Also, the dent is there so the jug doesn't burst if you accidentally drop it.
02:28:11The dent allows the expansion space that deals with the sudden pressure that happens when
02:28:15you drop the jug.
02:28:19Dental floss.
02:28:20Sure, it's important for your dental health, and it's easy to assume what you do with it.
02:28:24But dental floss is great in the kitchen as well, because it's a very precise cake slicer.
02:28:30Way better than a regular knife.
02:28:35Most kitchen shears have a serrated opening right there at the center where the blades
02:28:39and handles meet.
02:28:41It's something you can use to trim difficult herbs such as rosemary, thyme, or chives.
02:28:47Because of this opening, you don't need to pick the leaves off by hand, but de-stem them
02:28:51in one motion.
02:28:54The majority of gelatin containers or single-serving yogurts come with a tinfoil lid.
02:29:00And in most cases, you can use this covering as a disposable spoon.
02:29:05Just peel away the covering, and after a couple of simple folds, you'll have a perfect little
02:29:09spoon for your midday snack.
02:29:13If you look at it on the street, you'll think a fire hydrant is about three feet in height.
02:29:17But the actual size of the device used to provide water supply to firefighters all over
02:29:21the world is twice as large.
02:29:24That is, if you count the rest of the hydrant, which is hiding underground.
02:29:27They're mostly red, and it's not just a matter of urban design.
02:29:31First of all, they need to be of bright, easily noticeable colors so firefighters can spot
02:29:35them fast when they need to.
02:29:37The choice of color depends on how much water the hydrant can hold.
02:29:41It can sometimes vary depending on the location, but here's the breakdown.
02:29:45A red fire hydrant can splash 500 gallons of water per minute, while an orange one at
02:29:51least 1,000 gallons.
02:29:54Green ones mostly process 1,500 gallons of water per minute, and the most plentiful ones
02:29:58colored blue can generally contain over 1,500 gallons.
02:30:03Hey bowling fans, isn't it super annoying when your bowling ball gets cracked?
02:30:08Turns out that most of them get damaged because of incorrect storage or spikes in temperature.
02:30:14Now come on and face it, since it's already cracked a bit, aren't you curious what's
02:30:17actually inside the bowling ball?
02:30:19Because I sure am.
02:30:21Let's have a look.
02:30:22They mostly make the inner core of the ball of powdered metal oxides, like calcium or
02:30:26iron oxide, then mix them with some resin and catalyst to harden the whole mixture.
02:30:32So that light bulb shape you now see inside of the ball is actually its heaviest part.
02:30:37It also influences how your bowling ball rotates when going down the lane.
02:30:42The same goes with spray paint cans.
02:30:44When you shake it, it makes a weird noise, but what is that thing in there?
02:30:48It's called a pea, and it's meant to hold the paint mixture in place and maintain its
02:30:52shape.
02:30:53They generally make it out of plastic, metal, or ceramic.
02:30:56It basically acts as a whisk to make sure your paint is well mixed together before you
02:31:00apply it to your surface of choice.
02:31:03Ever wondered how soda bottles keep that refreshing fizz for that long?
02:31:07Well, they have a little plastic ring fastened to the lid.
02:31:11They place it there to keep the gas from escaping and making the soda go flat, even if you shake
02:31:16it around in your bag the whole day.
02:31:19Speaking of things we use on a hot summer's day, wait, wait, don't put your baseball cap
02:31:23on just yet.
02:31:25Take a look at it for a minute and you'll notice there's a small button on the very top.
02:31:29Is it functional or is it just there for the sake of design?
02:31:33Way back when people started using fabrics to cover their heads, some say the button
02:31:36was actually functional.
02:31:38Since it's on top of the cap where the fabric panels come together, the top button helps
02:31:43keep the cap crown in one single piece.
02:31:46Now with recent advances in fabric and pattern design, the button is more of an aesthetic
02:31:50feature.
02:31:51It's used to cover up the joint point of the fabric panels.
02:31:54Your cap might not have a button at all, but don't you think a cap actually looks better
02:31:58with one?
02:32:00Cotton pads have two sides and if you take the time to look at them carefully, they're
02:32:04actually different in texture.
02:32:06Just in case you've ever wondered why, the textured side is for applying makeup and the
02:32:11even side is for removing it.
02:32:14Bookworms, this one is for you!
02:32:17Dust jackets that come with a lot of hardcover books are not just meant to make your book
02:32:20look pretty, they also double as a bookmark.
02:32:24Just fold the pages you've already read underneath the inside of the jacket and voila!
02:32:29Next time you reach out for your favorite shirt, take a look at the top buttonhole.
02:32:33It should be stitched horizontally and all the other ones are vertical.
02:32:37Turns out that the dress shirt was designed this way since the first and the last buttons
02:32:41were the first ones to unbutton throughout the day.
02:32:45They then changed the direction of the buttonhole to ensure the shirt would stay nice and fitted
02:32:49before you're ready to take it off.
02:32:52These days we have so many variations of this awesome dessert that it's hard to imagine
02:32:56we've ever lived without it.
02:32:58You can find different types of cookie dough ice cream or even chocolate chip cookie cake
02:33:02basically everywhere, but the famous cookie wasn't actually invented until 1930.
02:33:08The story goes that a woman named Ruth Graves Wakefield was preparing some chocolate cookies
02:33:12as she was waiting for some guests to arrive.
02:33:15She soon figured out she was out of baker's chocolate, a crucial ingredient for the classic
02:33:19cookies.
02:33:20To fix things up, she chopped up a block of semi-sweet chocolate thinking it would eventually
02:33:25spread out evenly throughout the batter given the heat of the oven.
02:33:28Things didn't necessarily go as planned, but hey it's great they didn't because this is
02:33:32how she invented this modern dessert we now can't get enough of.
02:33:38And speaking of popular snacks, the potato chip is even younger than the chocolate chip
02:33:42cookie.
02:33:43Well, at least historically.
02:33:45There are many stories trying to explain how it was invented.
02:33:49One of them goes like this.
02:33:50A chef named George Crum based in New York put the chips together in 1953.
02:33:56He decided to try a different cooking solution when one of his customers didn't have nice
02:34:00things to say about his french fries.
02:34:03He said they were too thick and kind of mushy.
02:34:06Then Crum came up with potatoes that were thinly sliced and fried until brown.
02:34:11People absolutely loved the dish and they welcomed the first ever batch of chips with
02:34:16open arms.
02:34:18Ice cream anyone?
02:34:19If the story is true, back in 1904 at the St. Louis World's Fair, one ice cream shop
02:34:25owner ran out of cups to serve his dish.
02:34:27So he fashioned a waffle into the shape of a cone and the rest was history.
02:34:32Ok, I'll admit it, chewing gum like treats have been around since the ancient Greeks.
02:34:38So this one isn't particularly a revolutionary discovery, but the actual gum we buy today
02:34:42wasn't there until the late 1800s.
02:34:46An American inventor named Thomas Adams wanted to mix together different chemicals to create
02:34:51rubber.
02:34:52He tried and failed for that matter to play with chicle for his experiment, but ended
02:34:56up fashioning this neat treat.
02:34:58They still use chicle to this day to produce most chewing gums.
02:35:02Back in the 1800s there lived a man named Jean-Baptiste Jolly who worked in the fabric
02:35:07industry as a textile maker.
02:35:09How he came up with this next invention that we use a lot these days has less to do with
02:35:13him and more to do with his maid.
02:35:16The story goes that the woman accidentally knocked a kerosene lamp over onto a table
02:35:21cloth.
02:35:22Instead of getting upset over the damaged fabric, Jolly noticed that the substance actually
02:35:27made the material cleaner.
02:35:29Figured it out yet?
02:35:30Yep, that's how the idea for the very first dry cleaner popped up.
02:35:34A very neat accident, if I do say so myself.
02:35:38Now this one I loved.
02:35:40Did you know matchsticks were initially called friction lights?
02:35:43Or at least that's how their inventor, a chemist, named John Walker, called them back in 1826.
02:35:50He scraped a stick coated in chemicals across his hearth totally by accident one day and
02:35:55realized that they ignited and created a spark.
02:35:59Initially made out of cardboard, they were then made using wooden splints and sandpaper.
02:36:05Back in the 1940s a man named Harry Coover stumbled upon a chemical formulation that
02:36:10seemed to stick to everything it touched.
02:36:13The scientific community at the time didn't look much into it as the formula didn't seem
02:36:17to have many applications back then.
02:36:20It wasn't until 1951 that he looked a bit more into the formula and decided to repurpose
02:36:25it.
02:36:26Along with a fellow Eastman Kodak researcher named Fred Joyner.
02:36:29They gave it a proper full name.
02:36:32But you must know it by the shorter version, super glue.
02:36:37It also has many uses in security these days that it's hard to believe that we didn't come
02:36:41up with this one on purpose.
02:36:43Back in 1903, a scientist named Edward Benedictus knocked over a flask by accident.
02:36:50He looked down and was amazed to see that the glassware had just slightly cracked but
02:36:54maintained its shape.
02:36:56He was expecting it to break into a million tiny pieces.
02:36:59Curious about this hidden feature, he looked into it and figured out what was keeping the
02:37:03glass together was a substance coating the inside of the glass.
02:37:07Ta-da!
02:37:08That's how humanity came up with safety glass.
02:37:13There's nothing better than a nice piece of buttered toast for breakfast, if we're not
02:37:17counting hot fudge sundaes.
02:37:20But if you find it harder to spread out cold butter over your toast, here's an idea.
02:37:24Use a cheese grater, figure out the amount you need, and grate the product.
02:37:29The process will also soften the butter, making it easier to spread, and you won't have to
02:37:33melt a too large amount of it in the process.
02:37:36But still, that hot fudge!
02:37:39Dried pasta comes in all sorts of different shapes and sizes for a reason.
02:37:44That's because each type of pasta goes best with a particular sauce.
02:37:49Pasta shells, for example, are perfect with denser and chunkier sauces.
02:37:53Why?
02:37:54Because the sauce gets inside the shells, making it easier to serve and eat the dish.
02:37:59The ribbed outer surface also helps with covering the shells in the sauce.
02:38:05If you ever end up burning your cookies, you can save them with your trusty grater too.
02:38:10Just grate off the blackened parts after carefully taking the cookies from the baking tray.
02:38:16Be careful and wait until the cookies have cooled down.
02:38:19Also, if you ruin their shape a bit, you can always dip them in some melted chocolate.
02:38:25After the chocolate cools down, you'll have perfectly shaped cookies.
02:38:29Although, after it gets past your lips and beyond, does the shape of the cookie actually
02:38:34matter?
02:38:35Just sayin'.
02:38:37If you like adding a lot of ingredients to your sandwiches but don't really appreciate
02:38:42it when the bread gets soggy, there is a way to reduce the amount of moisture.
02:38:46Pick your sliced tomatoes or cucumbers and place them between two paper towels for up
02:38:51to 5 minutes.
02:38:52After that, you can use them.
02:38:54Also, make sure to spread butter, cheese, or sauces, like mayo or ketchup, onto the
02:39:00bread first.
02:39:01This will help you seal the bread and keep moisture at bay.
02:39:06Some people think that the little white string that you find near an egg yolk needs to be
02:39:11removed before you cook the egg.
02:39:12Well, I'm here to tell you that these strands are called chalaza, and you don't actually
02:39:17need to get rid of them.
02:39:18They help keep the yolk in place, at the egg's center.
02:39:21A chalaza is not going to mess up the consistency or the taste of your food, so removing it
02:39:27is completely up to you.
02:39:29Ever notice that most juice boxes come with two flaps, one on each side?
02:39:34Those are actually handles.
02:39:36Manufacturers design the boxes this way to make it easier for us to hold them.
02:39:41This way, we don't end up squeezing the box, making the juice spill out.
02:39:47Now you don't need to be a baking pro to know that you can use both white and brown
02:39:51sugar in your recipes.
02:39:53But have you ever wondered what the difference between these two is?
02:39:57It turns out that the only thing that sets them apart is that, during production, a small
02:40:02amount of molasses is added to the brown sugar.
02:40:06Molasses is basically a sort of syrup you get when processing sugarcane.
02:40:10It's usually removed during the refining process.
02:40:13That's how white sugar is produced.
02:40:16But if some amount of molasses remains in the final product, we end up with brown sugar,
02:40:21with its specific taste and darker hue.
02:40:24It's a good thing.
02:40:27There are a lot of things you can put in your dishwasher, apart from your dishes.
02:40:31For example, you can clean such things as your silicone oven mitts or the knobs of some
02:40:36kitchen appliances, like your oven or stove.
02:40:40Some kitchen sponges and reusable towels may be safe to clean in the dishwasher as well.
02:40:45Speaking of kitchen cleaning products, there are a lot of things you can do with dish soap,
02:40:50like de-griming your patio furniture.
02:40:53Just add a bit of dish detergent to some warm water and use the solution to wipe down your
02:40:58outdoor furniture with a piece of cloth.
02:41:00Finally, rinse it clean using your garden hose.
02:41:04You can also use dish soap to get rid of greasy stains on your clothes, be it pasta sauce
02:41:09or salad dressings.
02:41:11Hey, sometimes we miss our mouths!
02:41:13So just apply a little dish detergent to the stain and then rinse with water.
02:41:18Use non-colored soap for lighter clothes.
02:41:21For more difficult stains, let the dish soap sink in for a bit, then throw the piece of
02:41:25clothing in the washer as usual.
02:41:27And think about maybe getting a bib.
02:41:30If none of the methods have helped you organize your closet, and you're still overwhelmed
02:41:35with large piles of clothes, there's a simple way that might be effective.
02:41:39It's called the one-in-one-out rule.
02:41:43That means for every new piece of clothing you buy, you need to get rid of one you already
02:41:48have.
02:41:49That means you'll always be decluttering your space.
02:41:52To make it easier to find something in your closet, good luck!
02:41:56Keep your most-used items at eye level.
02:41:58This way, they'll be easier to find and pull out when you're in a hurry.
02:42:02Those items that you tend to use less often, like your evening clothes, for example, can
02:42:07stay on the shelves above or below your eye level.
02:42:11You can make good use of old spice tins.
02:42:14If you glue some powerful magnets to the inside of the tins, they can double as magnetic shelves.
02:42:19You can use them for all sorts of everyday items, like kitchen pliers, ice cream scoops,
02:42:25or even cutlery.
02:42:27You can also place them on any metallic surface, like your refrigerator door.
02:42:31They'll blend in nicely with your kitchen magnets.
02:42:35Hidden in your laundry room, there's a great tool for picking up pet hair.
02:42:39It sometimes works better than lint rollers.
02:42:42Take a dryer sheet and, using some elbow grease, you'll get rid of that dog or cat hair in
02:42:47no time.
02:42:49It works on all sorts of surfaces, but it's especially effective for upholstered furniture.
02:42:55If you don't like it when a door starts squeaking whenever you enter a room, get a
02:42:59bar of soap and rub it straight on the hinges.
02:43:02This will only help for a while, though, but it'll do the trick until you manage to get
02:43:07to a hardware store.
02:43:08And, you know, buy some oil.
02:43:11Have you ever noticed that in some elevators, there's a star next to the number of a specific
02:43:17floor?
02:43:18No, it's not to indicate where my office is.
02:43:21It's there to point out where the nearest exit is.
02:43:24And it's not always on the first floor.
02:43:26It's most likely located on the floor closest to the street.
02:43:30Have you ever wondered why stop signs are red?
02:43:33Well, back in the day, they didn't actually have any particular color at all.
02:43:38Before the 1920s, they didn't even have a standardized shade.
02:43:42In 1922, though, someone came up with the octagon.
02:43:46But initially, it was painted yellow.
02:43:49All because the red coloring tended to fade out too quickly because of sun exposure.
02:43:54So yellow turned out to be the best option.
02:43:57It took another 30 years for fade-resistant enamel paint to be invented.
02:44:01We ended up changing the color of the stop sign back to red.
02:44:05After all, it's still the best color if you want something to be easily noticeable.
02:44:10Do you know there's a type of rose that can grow taller than people?
02:44:15According to the Guinness Book of World Records, the tallest rosebush ever found grew in Vienna,
02:44:21Austria.
02:44:22It was a staggering 28.5 feet tall.
02:44:25Yes, it arose to a great height.
02:44:28In the same way we all have unique patterns on our fingerprints, no two tigers have the
02:44:33same set of stripes.
02:44:34It makes it easier for people working with this feline species to distinguish one tiger
02:44:39from another.
02:44:41I'll bet you didn't know the White House has its own flour shop hidden in the basement
02:44:45of the building.
02:44:46It's supposed to provide flour arrangements for all sorts of events that take place there.
02:44:52It's probably no surprise that pizza has become an American staple dish despite its
02:44:58Italian origin.
02:44:59People in the US love it so much that they buy 350 slices of pizza every second in the
02:45:06States.
02:45:07Man, I'm not getting my fair share.
02:45:09To manage the huge demand for this delicious dish, around 17% of all restaurants in the
02:45:15US are pizzerias.
02:45:17Finally, there's a way to make lemon juice without the seeds getting into your beverage.
02:45:23Try cutting the fruit in two and squeezing it with a pair of kitchen tongs.
02:45:27The pointed end of the lemon should be facing down.
02:45:30The juice will flow down, but the seeds will remain inside the lemon.
02:45:35Ooh, lemony!
02:45:36It goes well with pizza.
02:45:40Crackers have holes in them to stop them cracking and breaking during baking.
02:45:44If the holes weren't there, steam would build up inside the cracker and make it collapse.
02:45:50Take a look at a soda bottle and you'll notice a disc inside the bottle cap.
02:45:55This helps seal in the liquid and the drink's fizz, stopping it from going flat.
02:46:00The long neck on your soda bottle is designed like that to encourage you to hold it there.
02:46:05That way, the heat from your hand will only warm that top bit of the bottle instead of
02:46:10heating up your whole drink.
02:46:12It's always hard to see your food in the microwave because of that pesky black grate on the window.
02:46:18But it's there to stop harmful microwaves from escaping.
02:46:21Called the Faraday shield, it protects you as well as ensures that your food cooks properly.
02:46:28Food items like chips come with about 43% nitrogen inside their package.
02:46:33It might seem like they sell you half a bag of air, but it's exactly the opposite.
02:46:38Oxygen, the gas we breathe, would react with the chips inside the bag and make them go
02:46:43rancid quickly.
02:46:44It's called oxidizing for a reason.
02:46:47Nitrogen, on the other hand, is an inert gas that helps keep the foodstuffs fresh and also
02:46:53protects them from breaking during transportation.
02:46:56A bag of chips that has this gas cushion lets you enjoy your crunchies without them turning
02:47:01to potato crumbs.
02:47:03Donuts have holes in them so that the inside and outside cook evenly.
02:47:08Before the holes were added, the inside would often be greasy and doughy while the outside
02:47:13was crisp.
02:47:15Margins on paper aren't for writing in dates and numbering lists.
02:47:19They were originally added to serve a protective function.
02:47:23Back in the day, rats used to be a pesky problem in people's homes, and paper was one of their
02:47:28favorite snacks.
02:47:30Margins were added as a safeguard so that the rats would nibble on blank paper rather
02:47:35than taking a bite out of your important work.
02:47:38That hole in your hollow lollipop stick isn't to prevent choking should it ever be swallowed.
02:47:44It's actually there to keep the candy in place.
02:47:47Excess candy flows into the hollow tube, and the hole, which when it hardens, keeps the
02:47:52pop in place.
02:47:54If it was a smooth stick, the candy would slide off easily.
02:47:58Tubes come with so many attachments, but do any of us really know what that one with
02:48:03long bristles is for?
02:48:05It's for dusting and is perfect for cleaning framed art, blinds, and lampshades.
02:48:11What's the difference between a wooden hanger and a plastic one?
02:48:15Aside from helping keep your clothes in shape, cedar wood hangers also repel moths and bugs.
02:48:22Salt isn't just used for cooking.
02:48:24It can get rid of tough smells.
02:48:26Rubbing salt on your fingertips after chopping garlic should remove the smell.
02:48:31It also works on shoes.
02:48:34Toasters have a secret slide in the bottom that can be removed, so you can clean out
02:48:38all those annoying breadcrumbs.
02:48:41If you ever had problems with popping chocolates from the box, look at those little holes around
02:48:46them.
02:48:47They're there to help you.
02:48:48If you push a hole right next to the candy, it'll jump out easily.
02:48:53When you take a sip from a coffee cup with a lid, it decreases air pressure inside the
02:48:58cup, so air tries to get in.
02:49:00The tiny hole on the lid allows air to enter that way, so liquid can smoothly pour out
02:49:06the main hole.
02:49:08More on beverage lids.
02:49:10The small button on them let restaurant workers and customers, too, understand what's in
02:49:15a cup.
02:49:17Near each button, there's a name.
02:49:19Just look at which one is pushed down.
02:49:22The numbers on the fruit stickers tell you how exactly they were grown.
02:49:26If there are four digits and the first is four or three, the fruit has been sprayed
02:49:32with pesticides.
02:49:33If there are five digits and the first is nine, the fruit has been grown organically.
02:49:39If there are five digits and the first is eight, the fruit has been genetically modified.
02:49:46When you're on your way back to the car after bagging up everything you bought, use loops
02:49:51on a shopping cart to hang the bags.
02:49:54Now softer items like bread, eggs, fruit, and veggies won't get squashed by the heavier
02:49:59goods.
02:50:01If you don't have anyone to hold the other end of your tape measure when you try to measure
02:50:05something, tap a nail on it.
02:50:08Now simply hook your tape on it using the tiny hole all tape measures have.
02:50:14The square-shaped spoon that goes with a McFlurry helps to mix the ice cream toppings through
02:50:20the dessert.
02:50:21The spoon hooks directly to a machine and spins around.
02:50:25Padlocks that are used outside quickly get out of order because of rain.
02:50:30See this little hole in the bottom?
02:50:32It's made for pouring engine oil inside.
02:50:35Do this and the key will again turn in the lock without any difficulty.
02:50:41You keep banging the bottom of a glass ketchup jar, but nothing's coming out.
02:50:45Here's a little tip, turn your ketchup bottle at an angle and tap on the middle of the neck.
02:50:52In many fast food restaurants, customers fill tiny folded paper cups to get a portion of
02:50:57ketchup or mustard.
02:51:00Here's the news, the cups are supposed to unfold and turn into small paper platters
02:51:05to hold a great deal more sauce.
02:51:08That little hole on the handle of a pot or a frying pan isn't just for hanging them on
02:51:13the wall.
02:51:14During cooking, put the end of your utensil in the hole and it'll be propped over the
02:51:19pot to save your kitchen from extra mess.
02:51:22The blue or any other dark color bristles on your toothbrush are meant to remind you
02:51:27when it's time to get a new one.
02:51:29If you see that bristles have become pale, change the toothbrush or its head.
02:51:34An extra hole at the upper part of the sink has multiple hidden functions.
02:51:39First, in case someone forgets to close the tap, the water won't overflow and the bathroom
02:51:45won't get flooded.
02:51:46Second, thanks to that hole, the water drains faster as it gives an escape for the air,
02:51:52helping the water flow down.
02:51:54Most metallic zippers have a hidden lock inside them to save you from awkward situations such
02:52:00as an undone fly.
02:52:02Don't leave the zipper handle in an upward position.
02:52:05When you pull it downwards, it automatically locks.
02:52:08It's all thanks to those tiny grooves hidden underneath the handle.
02:52:13Spoiled milk emits gases like most foods when they go off.
02:52:17A classic plastic milk jug has a concave shape on one side.
02:52:22So when the gases expand inside the jug, it expands too and the concave shape curves out.
02:52:29Also, if you want to save some milk for later and freeze it, the jug will expand when the
02:52:34milk gets solid as well, occupying more space in a jug.
02:52:39Bath foam isn't only for fun or a nice smell.
02:52:42It also helps regulate the temperature.
02:52:45The bubbles keep the water hot, so you can enjoy a bath a bit longer.
02:52:49Anyway, it works for acrylic bathtubs only.
02:52:52Those made of metal lose heat really fast either way.
02:52:57Many cups and mugs have little grooves on the bottom on purpose.
02:53:01They're designed for washing machines.
02:53:03The grooves let the water flow and not spill over your feet when you take the cup out.
02:53:08Also, those grooves let the air flow so the cup doesn't crack even if the tea is scalding.
02:53:15A point on an ointment cap is there for a reason too.
02:53:19Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers
02:53:24unless you're ready to say goodbye to your nails.
02:53:27A point easily opens even the most safely sealed tube.
02:53:32Escalator brushes aren't for keeping your shoes clean and polished.
02:53:36It might be tough to apply wax right on that brush while the escalator's on the move.
02:53:40It's for your safety.
02:53:42Brushes won't let you come close to the edge, so a long coat or bootcut jeans won't end
02:53:47up in between the steps.
02:53:50All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
02:53:56The lid has the same shape as the candy.
02:53:59Turn the container upside down, gently shake it, and slowly open it.
02:54:03You'll notice only one candy stuck between those lid grooves.
02:54:07So if you just open the container and shake it until five or even more candies fall into
02:54:12your mouth, it means you've been eating Tic Tacs wrong all this time.
02:54:17The pom-pom on top of your beanie wasn't put there as a fashion accessory.
02:54:22The pom-pom was originally added to the hat to prevent sailors from banging their heads
02:54:27on the ceilings of the ships that were too low.
02:54:58If you take a closer look at it, you'll probably notice that the seam is inside out,
02:55:03and it's not by accident.
02:55:05In fact, you're not supposed to shake up the bag to open it.
02:55:08You gotta place the bag over a garbage can like a hat, and then just push the middle
02:55:12of the bag down to the can.
02:55:14No worries, you're not the only person who didn't know that.
02:55:17This eye-opening trick went viral online and got millions of views.
02:55:21Imagine that you need to dye your hair, paint walls, or mold a clay mug immediately, but
02:55:26you don't have a protective suit on hand.
02:55:28Here comes the good news.
02:55:30You can make one out of a plastic bag.
02:55:32It will take you less than a minute.
02:55:34Just find a bag wide enough to fit your torso.
02:55:37Cut one hole in the bottom of the bag for your head, and make two holes for the arms
02:55:40on the sides.
02:55:41Voila!
02:55:42Feel free to make a hat from another plastic bag to protect your hair.
02:55:46When the job is done, you can wash this handmade suit and reuse it.
02:55:50Our next hack is for those who don't like to waste money.
02:55:53You can use a real plastic bag instead of a raincoat that looks like a plastic bag anyway.
02:55:58Just make a round cut for your face, and you're ready to go.
02:56:01You can reuse it as many times as you want.
02:56:04You can use a plastic bottle to create a recycled bag dispenser.
02:56:08Take a large bottle.
02:56:09It can be either a bottle of soda or washing gel.
02:56:12What matters is its shape.
02:56:14It must be straight so you can easily store bags inside it.
02:56:18Wash the bottle, dry it, and cut off the bottleneck and bottom.
02:56:21Turn it upside down.
02:56:22There you go.
02:56:23Your bag dispenser is ready.
02:56:26You can use your imagination to paint and decorate your DIY project with stickers and
02:56:30lettering to your taste.
02:56:32When the design is ready, attach it to the back of the bottle and stick this holder to
02:56:36the wall in your kitchen or one of the cabinet doors.
02:56:39Imagine you've been planning a perfect hiking weekend for ages.
02:56:43But when you actually get there, it starts raining.
02:56:46Don't rush back home.
02:56:47Plastic bags will serve you well if you need to put your clothes or equipment on wet grass.
02:56:52Also, you can make an emergency sleeping bag cover using a large garbage bag.
02:56:57After the rain, it will serve as a nice mattress to lay under your sleeping bag to protect
02:57:01it from moisture and provide an additional layer for a cozy nap.
02:57:05Just fill the bag with some soft leaves and straw that lie on the ground, and there you go.
02:57:10A large garbage bag can be your best friend when you're camping with friends somewhere
02:57:14in the wild.
02:57:15You can turn it into a temporary handmade shower, toilet, or even a dressing room out of it.
02:57:21Just hang it on the tree and no one will spy on you.
02:57:24If you went for a walk wearing a pair of your favorite shoes that get wet easily, here's
02:57:28an easy tip to keep your socks dry.
02:57:30Put plastic bags over your socks, tuck the edges of the bags into your socks or trousers,
02:57:36and then put your shoes on.
02:57:38There's one obvious drawback, though.
02:57:40Feet can slip inside the shoes, so be careful.
02:57:43These plastic socks are also handy when you're trying to put on tight jeans that usually
02:57:47make your feet stick inside them.
02:57:50Have you ever had your bag torn at the worst possible moment?
02:57:53A plastic bag with handles can become an emergency backpack.
02:57:57Just place your stuff inside the bag, put your hands through the handlers, and you're
02:58:00ready to go.
02:58:02A garbage bag is also a good material for book covers.
02:58:05You can reuse multicolored bags to create a unique pattern for your favorites.
02:58:10You're moving to a new house and packing all your belongings.
02:58:13Suddenly, you run out of boxes.
02:58:15Sounds familiar.
02:58:16No problem.
02:58:18Grab a package of large garbage bags and pack the remaining stuff.
02:58:21Unlike boxes, this packaging will protect your property from rain or snow.
02:58:26Garbage bags are especially good for packing blankets, pillows, and stuffed toys.
02:58:31If you need to make a vacuum packing for your clothes or stuffed toys, simply put your belongings
02:58:37in a trash bag, place a tube from your vacuum cleaner inside the bag, and then turn it on.
02:58:42The vacuum cleaner will remove all your excess hair from the bag, and you'll save space
02:58:46in your suitcase or basement.
02:58:49Someone really special has invited you home to cook a romantic dinner together.
02:58:53Finally, you want to show all your extraordinary cooking skills, but your special someone doesn't
02:58:58have an apron, and you don't want to mess up your new outfit.
02:59:01No worries.
02:59:02Make an emergency apron using a large garbage bag.
02:59:05It will surprise that special someone even more.
02:59:09Speaking of stylish outfits, are you familiar with the term garbage bag dress?
02:59:14Celebrities and famous fashion brands shock the audience with outfits looking like trash
02:59:18bags from time to time.
02:59:20Some of them actually make outfits using garbage bags like fabric.
02:59:24It's a popular option for young artists who can't afford to buy and use expensive fabrics.
02:59:29Garbage bags are very flexible, so they are a useful material for making patterns for
02:59:34future outfits.
02:59:36When it comes to garbage bags, the DIY project's possibilities are almost infinite.
02:59:41People use bags to make lampshades, clothes covers, small cosmetic bags, makeup organizers,
02:59:47recycled glasses, and whatnot.
02:59:49Some even weave baskets, bags, and floor rugs out of them.
02:59:53It's pretty easy to handcraft a rug.
02:59:55You need to cut several bags into equal strips and weave a long braid from these strips.
03:00:00Now twist this braid into a spiral and tire glue each layer together.
03:00:05To secure this entire construction from breaking, you can screw your rug on a sewing machine
03:00:09from the middle to the edges, as if you're drawing a star.
03:00:12This plastic braid can also serve as emergency laces, a rope, or a handmade ribbon for decorating
03:00:18gifts and flowers.
03:00:20Filmmaking is another yield where garbage bags can be real stars.
03:00:24If you're shooting indoors and the sunlight is too sharp, you can put white garbage bags
03:00:28on all windows to diffuse the light or to set the white balance.
03:00:32Black lightproof garbage bags may serve you as a shading curtain to get rid of the sunlight
03:00:36in the room whatsoever.
03:00:38Feel free to use a white bag to create a diffused light bulb.
03:00:41Inflate the bag like a balloon and put it next to a lamp, but make sure to use a LED
03:00:46light so it doesn't get too hot.
03:00:48Everyone knows that touching a plastic bag with a hot iron is a bad idea because it will
03:00:53melt, but this lets us create unique shapes from this colorful and affordable material.
03:00:59Want to make a unique designer vase?
03:01:01Take a bowl and cover it with paper tightly.
03:01:04Then wrap the matching strips of plastic bag around the bowl.
03:01:07Now place another layer of paper on the top and gently iron over the entire surface of
03:01:11the bowl.
03:01:12Voila!
03:01:13The plastic's melted and you've got a new stylish and eco-friendly vase.
03:01:18Garbage bags can produce very cool sound effects.
03:01:21If you live in a desert where it never rains and need to recreate that relaxing sound,
03:01:26use a plastic bag.
03:01:27It's always better to speak up like an adult, but if that doesn't work for you, here's a
03:01:31quick fix.
03:01:33Next time some annoying person calls you, don't bother to make excuses why you can't
03:01:37talk right now.
03:01:38Just grab a garbage bag and rustle it into your phone speaker yelling,
03:01:42Hello?
03:01:43Hello?
03:01:44I can't hear you!
03:01:45Confession time!
03:01:46Have you ever used this trick?
03:01:48That's it for today.
03:01:49So hey, if you pacified your curiosity, then give the video a like and share it with your
