00:00:00Whether it's something as simple as a button on your jeans, or a part of a more sophisticated mechanism,

00:00:07here are 26 secrets on everyday objects that you probably didn't know.

00:00:13You use door handles every day, so it's normal to worry about the number of germs that could accumulate there.

00:00:19However, it is partly for this reason that we make brass handles.

00:00:24This alloy has an antimicrobial effect

00:00:26and eliminates the microorganisms that hoped to start a colony on your door handle.

00:00:32Your pants have this fifth pocket, which is often considered as a small useless pocket.

00:00:37Originally, it was there to provide a safe place for your watch,

00:00:41which became necessary during its invention in 1901.

00:00:44It then continued to serve traditional purposes.

00:00:47Today, it remains a practical place to slip a few tic-tacs.

00:00:51You probably took these little rivets on your jeans for a kind of decorative motif.

00:00:56Just like this little pocket.

00:00:58In fact, they are incredibly important.

00:01:01They are there to provide additional support to the areas that support the most sought-after parts of your clothes,

00:01:06thus preventing them from tearing in an embarrassing way.

00:01:10This little button at the end of your seat belt does not seem to be in place.

00:01:15In fact, it is there so that your buckle always stays at the end.

00:01:19So that you do not have to fidget your seat belt every time you put it on.

00:01:24You are in a new car or a rental car,

00:01:26and the gauge indicates that the fuel is starting to run out.

00:01:29Inside, you do not know which side the tank is on.

00:01:32This can cause you to waste time at the gas station.

00:01:35However, know that the light of your fuel gauge is equipped with an arrow

00:01:39that tells you which side you have to fill your tank.

00:01:42Some car models may only have one pipe as a light,

00:01:46but then it is represented on the side where the tank is located.

00:01:50Hiking in the snow requires a particular type of shoe.

00:01:55Suitable shoes also have an additional eyelet in which your lace can pass.

00:02:00By passing your lace through these additional eyelets,

00:02:03you will provide more support to your ankles and feet,

00:02:06and you will also have more stability while you walk.

00:02:09When you walk, the bulbs are also a source of concern.

00:02:13The sweat in your shoes creates friction between your foot and these,

00:02:17which then contributes to creating the bulbs.

00:02:19The anti-sweat that you use for your laces will also help your feet not to sweat too much.

00:02:24Just make sure to use a transparent product.

00:02:28Cooking for others is always pleasant,

00:02:30but it happens that the guests are late.

00:02:33We are all guilty of that, aren't we?

00:02:37The additional drawer under your oven,

00:02:39where you keep all your spare pans,

00:02:41was actually designed to keep your food warm,

00:02:44which is ideal for waiting for guests who are late.

00:02:47Have you ever wondered how long this lock could last when it is outside,

00:02:51in the rain, to protect your bike?

00:02:55There is a small hole at the bottom of this one,

00:02:57which is used to evacuate water in order to avoid corrosion inside.

00:03:01It is also used to pour oil into it, which further extends its lifespan.

00:03:06This hole in the elevator door

00:03:08is not there to check who is inside

00:03:10before embarking on a journey with people you don't like.

00:03:13It is a lock hole in case it breaks.

00:03:17Ketchup bottles, sauces, and all the other condiments we like

00:03:21all reach a filling level where it becomes difficult to get the content out.

00:03:25In wine, you try to hit it, shake it,

00:03:28and push objects inside to encourage the tasty condiments to come out.

00:03:32Fortunately, there is an easier way to do it.

00:03:35The marking at the top of the bottle suggests where to hit or push.

00:03:39The sauce will come out more easily and more gently,

00:03:42allowing gravity to alleviate your frustration.

00:03:45The wooden belts are used to help repel unwanted insects

00:03:49and to prevent the proliferation of mushrooms that litter your clothes,

00:03:53because they are made of cedar wood.

00:03:56They contain oils with insecticide and fungicide properties,

00:04:00which were already used by the ancient Egyptians,

00:04:03even if it was for other purposes.

00:04:07We have all been more or less trained in the technique of dactylography

00:04:11and we know the correct way to use a keyboard.

00:04:14But you may not have noticed that the F and J keys had a small stop at the bottom.

00:04:18They are there to help you find the correct starting position

00:04:22with your fingers on the keyboard without having to look at it.

00:04:26If you were lucky enough to have the hublot seat in the plane,

00:04:30you must have noticed the small hole at the bottom of the window.

00:04:33It helps to equalize the air pressure in the plane.

00:04:36The window itself is made of acrylic and is not really glass,

00:04:40which prevents it from fogging up and allows you to admire the landscape during your trip.

00:04:44Originally, the windows of the planes were square.

00:04:47However, they broke continuously due to pressure changes.

00:04:51The round hubs distribute the pressure evenly,

00:04:55which guarantees you a pleasant trip and without bad surprises.

00:04:59For Nintendo Switch players,

00:05:02those who have tried to taste their cartridges will notice that they have a bitter taste.

00:05:06Manufacturers added it on purpose,

00:05:09because the size of the cartridges of the Switch is very small

00:05:12and could represent a danger for younger players,

00:05:15who may tend to put things in their mouths that they should not.

00:05:18The bitter taste of Denatonium's Benzoate

00:05:21therefore ensures that the cartridges will not be tasted for too long.

00:05:26The skin cosmetics containers have a secret number.

00:05:30It is used to inform you of the duration of use of the product,

00:05:34to ensure that it does not cause the opposite effect by damaging your skin.

00:05:40The caps of the pens have a hole at their ends.

00:05:43They are not there to help your pen breathe and increase its performance.

00:05:46But to help you breathe,

00:05:48you, in case, while you are sitting in class or at work,

00:05:51you would wrinkle your cap and wash it by mistake.

00:05:54Don't panic!

00:05:56Manufacturers thought of everything.

00:06:00When you travel by car or with any other means of terrestrial transport,

00:06:04and you try to drink your favorite soda with a straw,

00:06:07you sometimes have a hard time doing it.

00:06:09You just have to turn the cap of the pen

00:06:12so that your straw fits easily inside

00:06:14and that it is easier to drink with.

00:06:18There are always spare buttons when you buy new clothes

00:06:21as well as a small piece of fabric.

00:06:23But it is far too small to repair the part that always tears first.

00:06:27The fabric is actually there so that you can test it when washing

00:06:31so as not to accidentally damage your brand new clothes.

00:06:35It can be difficult to determine the amount of dough you need to cook.

00:06:40But the hole inside your spaghetti spoon,

00:06:43which seems to be there to drain the water,

00:06:45is actually there so that you can measure the amount of raw dough to cook for each person.

00:06:51New shoes are always sold with strange little packages.

00:06:54It is silica gel.

00:06:56It is used to reduce the humidity of the air

00:06:58in order to avoid any mushroom development

00:07:00while your shoes are waiting to find a buyer.

00:07:04You need a good dose of chemistry to get this silica,

00:07:06and it is very effective,

00:07:08able to absorb 50% of the humidity.

00:07:11So make sure you don't throw it away.

00:07:13The next time you need to dry your electronic appliances that have taken water,

00:07:17it is much easier than using rice.

00:07:20It is already quite difficult to drive at night.

00:07:22But it is even worse when the driver behind you turns on his road lights.

00:07:27Your rear-view mirror has a tab underneath.

00:07:29When you press it, it changes the angle of the mirror.

00:07:32The normal position is for day driving,

00:07:34and the other is for night driving.

00:07:36This will help you if the person behind you forgets to reduce his headlights.

00:07:42Although your screwdriver is ergonomic for your hand,

00:07:45you sometimes have to fight with a screw that is just too difficult to unscrew.

00:07:50The handle is also designed so that it can be easily inserted into a wrench,

00:07:55which allows you to apply more force

00:07:57to be sure to be able to remove this screw.

00:08:00The side panels of a climber seem to be a good place to get stuck.

00:08:05But to be honest, these long hairs that protrude

00:08:07are not there to give your shoes an extra sparkle.

00:08:10But as a security measure,

00:08:12they minimize the risk of getting objects stuck between the steps and the sides of the climber.

00:08:18The next time you get dressed, look at your shirt closely.

00:08:21Each buttonhole is sewn vertically,

00:08:24but look at the very last hole.

00:08:26It is sewn horizontally, isn't it?

00:08:28The lower part of your shirt is the one that endures the most tension,

00:08:32because that's where your hips are.

00:08:34This buttonhole is not designed like this by chance.

00:08:38It prevents your shirt from tearing when your hips move.

00:08:41The layer of foam that forms when you put foam bath in your bathtub is not just fun.

00:08:47It also acts as an insulator and keeps your bath warm longer.

00:08:51The pompom on the top of your hat was not placed there just to look pretty.

00:08:55Originally, it was sewn on the sailors' hats

00:08:58to prevent them from sticking their heads on the ceilings,

00:09:00often too low, of the ships.

00:09:03The crackers were pierced with holes

00:09:05to prevent them from breaking or cracking during cooking.

00:09:08If these holes didn't exist, steam would accumulate inside and break them.

00:09:13The numbers written on the stickers you find on oranges are not placed randomly.

00:09:18If there are four numbers and the first one is 3 or 4,

00:09:21it means that the fruit was grown according to the usual agricultural techniques.

00:09:26Five numbers starting with an 8 means that the orange has been genetically modified.

00:09:31Five numbers starting with an 9 means that the fruit is organic.

00:09:35The margins on the pages of notebooks are not just used to take notes,

00:09:38but were originally used as protection.

00:09:41At the time, rats were very present in houses

00:09:43and paper was one of their favorite food.

00:09:46The margins were therefore added so that the rats blinked white areas

00:09:49rather than those containing important writings.

00:09:52If you empty your Chinese meal on a plate,

00:09:55you're giving yourself trouble for nothing,

00:09:57just like the seasoning pots on paper in fast food.

00:10:00These cardboard boxes can be unfolded to form a plate of suitable size for your dish.

00:10:05The long neck of your soda bottle is designed to encourage you to hold it there.

00:10:10This way, the heat from your hand will only heat up the upper part of the bottle

00:10:15instead of heating up your whole drink.

00:10:17Why do the back of some jackets have a buttonhole without a corresponding button?

00:10:22Originally, coats and jackets were equipped with a corresponding button

00:10:26so that the person wearing them could lift up their collar

00:10:29and tie it around their neck to make it warmer.

00:10:32Over time, people stopped doing this and this button was removed,

00:10:35but many manufacturers have kept this buttonhole by tradition.

00:10:39It's always difficult to see food in the microwave

00:10:42because of this black grid stuck to the glass,

00:10:44but it's there to protect you from harmful waves.

00:10:47It's a Faraday cage.

00:10:49This lozenge on your backpack is a fishing rod.

00:10:52It's there so that you can pass cords through the holes

00:10:55to transport additional equipment.

00:10:58It's ideal for camping or long hikes.

00:11:01The golf balls are covered with little holes

00:11:03so that you can fly more easily in the air.

00:11:06This reduces the resistance and allows you to travel farther and faster.

00:11:11Make-up cotton has two different sides for a good reason.

00:11:15The bushy side is used to apply make-up,

00:11:17while the other side is used to remove it.

00:11:19The donuts are pierced so that the inside and the outside cook evenly.

00:11:24Before the addition of these holes,

00:11:26the inside was often greasy and doughy,

00:11:28while the outside was crispy.

00:11:30The charger of your laptop is equipped with small legs,

00:11:33but not for standing up.

00:11:35When they are unfolded,

00:11:36these legs allow you to wrap the cable around

00:11:38and hold it in place to prevent it from getting tangled or damaged.

00:11:42If you look at a bottle of soda,

00:11:44you will notice a disc inside the cap of the bottle.

00:11:47This disc seals the bottle hermetically

00:11:50to prevent the gas from escaping.

00:11:53The holes in the sock sticks

00:11:55are not intended to prevent suffocation in case of ingestion.

00:11:58They are there to keep the candy in place.

00:12:00The excess liquid flows into the tube through this hole

00:12:03and when it hardens, it fixes the sock.

00:12:06If the stick was smooth, the candy would slide too easily.

00:12:10The leather motorcycle jacket zipper

00:12:13is often sewn diagonally.

00:12:15It's not just a fashion effect.

00:12:17Vertically sewn zippers can be rolled up

00:12:19when you lean forward,

00:12:21but it's not a diagonal zipper.

00:12:23The little triangle on your fuel gauge

00:12:25tells you which side of the car

00:12:27the fuel gauge is on.

00:12:29You will never stop on the wrong side of the pump now!

00:12:33Vacuum cleaners are equipped with many accessories,

00:12:35but do you really know what this long-haired one is for?

00:12:38It's used to clean dust

00:12:40and is perfect for cleaning framed paintings,

00:12:42stores and junkyards.

00:12:44These little holes in the chocolate box tray

00:12:47actually have a function.

00:12:49You can stick it in the hole near the candy

00:12:51and it will come out without your fingers getting dirty.

00:12:54Some skyscrapers have completely empty floors.

00:12:57It's actually a way to bypass height limits.

00:13:00Most buildings have a limited number of floors.

00:13:03As these invisible floors are empty,

00:13:05they add height to the buildings

00:13:07and make it more impressive

00:13:09without increasing the number of real floors

00:13:11while respecting the construction contract.

00:13:13These hollow floors also prevent

00:13:15the spread of fires.

00:13:17Women's shirt buttons

00:13:19are traditionally placed on the left

00:13:21for a good reason.

00:13:23At the time, it was a sign of wealth

00:13:25because it meant that a maid

00:13:27you had dressed and had buttons on the left

00:13:29made it easier for her to button the shirt.

00:13:32Your cuticles are useful for something,

00:13:34so think well before getting rid of them.

00:13:37This little skin area is there

00:13:39to protect your nails from infections.

00:13:41Without it, bacteria and fungi

00:13:43can infiltrate.

00:13:45If you have a wooden belt and a plastic belt,

00:13:47in addition to helping to keep your clothes in shape,

00:13:49the cedar wooden belts

00:13:51repel mites and insects.

00:13:53If you look carefully at an elevator door,

00:13:55you will see a small hole.

00:13:57It is actually a lock hole

00:13:59used for maintenance or in case of emergency.

00:14:01These buttons scattered in your jean

00:14:03are rivets and they are placed

00:14:05in the most fragile places of the jean

00:14:07to protect it from tears

00:14:09due to tension or movement.

00:14:11The crown of the Statue of Liberty

00:14:13has seven points representing

00:14:15the seven seas and the seven continents.

00:14:17They have been added so that it can offer

00:14:19a little of its famous freedom

00:14:21to all the inhabitants of the world.

00:14:23The suitcases are often equipped with two locks

00:14:25that can be connected with a padlock

00:14:27to avoid theft.

00:14:29Salt is not only used to season,

00:14:31it also eliminates tenacious odors.

00:14:33Rubbing it on your fingers after chopping garlic

00:14:35will make the smell disappear.

00:14:37It also works on shoes.

00:14:39If you are in a hurry to go out

00:14:41put it in airplane mode

00:14:43to load it faster.

00:14:45Men's shirts have a loop in the back

00:14:47that allows you to hang them

00:14:49with a hook without crushing them.

00:14:51Vaseline has a secret utility.

00:14:53It is ideal to make scuffs disappear

00:14:55on leather shoes.

00:14:57It will also make them shine.

00:14:59Some car suitcases are equipped

00:15:01with an emergency lock

00:15:03in case you accidentally lock yourself inside.

00:15:05You are never too careful.

00:15:07You wait a little to find it

00:15:09The painted grids have a secret slide

00:15:11in the back that can be removed

00:15:13to remove the crumbs.

00:15:15Look at the keyboard of your laptop.

00:15:17There are buttons on the F and J keys

00:15:19but nowhere else.

00:15:21When your fingers are in the optimal position

00:15:23to type, your index fingers must rest

00:15:25on these two keys.

00:15:27These buttons have been added

00:15:29to be able to position your hands correctly

00:15:31without looking at the keyboard.

00:15:33If you don't have an index,

00:15:35maybe it's because you fed the sharks

00:15:37because we can't do anything for you.

00:15:41The new iPhone models

00:15:43with large screens

00:15:45have a practical option called accessibility.

00:15:47Thanks to this function,

00:15:49you won't have to struggle

00:15:51to reach the top of the screen.

00:15:53This function is in the phone's

00:15:55accessibility settings.

00:15:57It allows you to reach elements

00:15:59located at the top of the screen

00:16:01by swiping down

00:16:03on the lower edge of the screen.

00:16:05These buttons are there to wake up

00:16:07the sleeping drivers

00:16:09who are suffocating behind the wheel.

00:16:11When your tires drift on these strips,

00:16:13the noise and vibrations

00:16:15work like an alarm clock.

00:16:17Most kitchen scissors

00:16:19have metallic teeth

00:16:21in the middle.

00:16:23They allow you to use the utensil

00:16:25with multiple ends.

00:16:27They are placed between the handle of the handle

00:16:29to allow you to break nuts,

00:16:31crab shells, etc.

00:16:33You can also use these teeth

00:16:35to remove the aroma stems.

00:16:37If you have a three-ring audio jack,

00:16:39it means that your device

00:16:41can produce a stereo sound

00:16:43and your headphones

00:16:45can play the microphone.

00:16:47The black grid on the door

00:16:49of a microwave oven

00:16:51is called a Faraday cage.

00:16:53It prevents microwaves from escaping.

00:16:55If this were the case,

00:16:57your food wouldn't cook properly.

00:16:59The numbers on an egg

00:17:01indicate the method of production.

00:17:03The following two-letter code

00:17:05indicates the country where the egg was produced.

00:17:07And finally, there is a registration number.

00:17:09It indicates where the laying hen

00:17:11comes from.

00:17:13The first number of this code

00:17:15can vary from 0 to 3.

00:17:170 means that it is a biological egg.

00:17:191 means that it is a hen raised in the open air,

00:17:21which means that it was produced

00:17:23by a hen allowed to lay eggs outside.

00:17:252 means that it is an egg

00:17:27produced in a deep-bottom henhouse.

00:17:293 means that you are about to buy

00:17:31a battery-powered egg.

00:17:33The black strip that runs along the edges

00:17:35of your windshield is called the frit.

00:17:37It is a ceramic paint,

00:17:39baked in the oven,

00:17:41which first presents itself as a solid black strip

00:17:43near the edge of the windshield.

00:17:45It then dissolves into small dots.

00:17:47The frit makes the glass rougher

00:17:49and the adhesive adheres better to it.

00:17:51The frit protects the urethane mastic.

00:17:53It is the substance that fixes the glass to the frame.

00:17:55It also prevents the ultraviolet rays

00:17:57from melting the glue.

00:17:59As for the black dots,

00:18:01they help to distribute the temperature more evenly

00:18:03in the car.

00:18:05They are also very aesthetic.

00:18:07Without them, the contrast between the green

00:18:09and the dark strip would be too obvious.

00:18:11If you see a jean with an additional buckle,

00:18:13these are special jeans for cyclists.

00:18:15It is likely that it belongs

00:18:17to a line of clothing for those

00:18:19who go to work by bike.

00:18:21The main objective of the buckle

00:18:23is to hold your bicycle lock.

00:18:25The outer rings of the buckle

00:18:27are supposed to be used together.

00:18:29These rings are added

00:18:31so that you can attach them

00:18:33with a lock and push the pickpockets back.

00:18:35The keys are equipped with small feet.

00:18:37They were designed to allow you

00:18:39to tilt your keyboard.

00:18:41This way, you can see the keys you hit.

00:18:43On the other hand,

00:18:45a flat keyboard does not tire

00:18:47the wrists as much,

00:18:49and people who can type without looking at the keyboard

00:18:51absolutely do not need these feet.

00:18:53The olive spoon is also made

00:18:55of stainless steel,

00:18:57and its bowl-shaped head

00:18:59is pierced with a small hole.

00:19:01The main objective of this device

00:19:03is to lift the olives, cherries,

00:19:05pickles and other products

00:19:07contained in jars,

00:19:09tin boxes or liquid-filled bowls.

00:19:11The hole in the middle

00:19:13allows you to quickly and easily

00:19:15evacuate the liquid

00:19:17that accumulates in the spoon.

00:19:19What will they imagine next?

00:19:21They will be overcooked on the edges

00:19:23and will remain raw and sticky inside.

00:19:25By making a hole in the middle,

00:19:27the outside and the inside

00:19:29will be cooked at the same time.

00:19:31Round bowls without holes

00:19:33are usually filled with pastry cream,

00:19:35whipped cream or jelly.

00:19:37These bowls have no corners,

00:19:39which means there are fewer weak spots

00:19:41from which the filling can flow.

00:19:43If you grab a box of fruit juice

00:19:45a little too firmly,

00:19:47you could have glue everywhere.

00:19:49Lift the tabs on the sides

00:19:51of the box of juice.

00:19:53You can use them to hold your drink.

00:19:55Some cars have a small coffee cup

00:19:57sign on the dashboard.

00:19:59This is the vehicle's anti-sleeping mechanism.

00:20:01Some manufacturers

00:20:03equip their cars with a sleep detection system.

00:20:05It analyzes speed,

00:20:07wheel angle and trajectory deviations

00:20:09and determines whether it is time

00:20:11for the driver to take a break.

00:20:13If this is the case,

00:20:15the vehicle emits several sound signals

00:20:17and the coffee cups start blinking.

00:20:19The stickers on the fruits and vegetables

00:20:21you buy at the supermarket

00:20:23are filled with information.

00:20:25If there is a 4-digit code on the sticker,

00:20:27the product has been grown in the most common way.

00:20:29In most cases,

00:20:31this also means that pesticides

00:20:33have been used in the process.

00:20:35If the product is organic,

00:20:37its sticker has 5 digits

00:20:39and the first is 9.

00:20:41Genetically modified products

00:20:43also have a 5-digit code,

00:20:45and the second is 8.

00:20:47In the past, sugar was sold

00:20:49in the form of sugar bread.

00:20:51It was high and hard cones.

00:20:53At the time,

00:20:55to prepare the sugar for their tea,

00:20:57people first had to use special hammers

00:20:59to break a bread.

00:21:01Then they cut the sugar into smaller

00:21:03and prettier pieces.

00:21:05It was only in the middle of the 19th century

00:21:07that people invented the first press

00:21:09that cut sugar into pieces.

00:21:11In this way,

00:21:13the tip of your key

00:21:15can provide your screwdriver

00:21:17with a few additional turns.

00:21:19You just have to slide the tip

00:21:21with the hole on the screwdriver.

00:21:23You can also use this method

00:21:25when the angle is delicate.

00:21:27When you drive in the dark,

00:21:29you can be blinded by the headlights

00:21:31of the car following you.

00:21:33If you have a manual rearview mirror,

00:21:35find the tab at the bottom

00:21:37and tilt it.

00:21:39The mirror has a reflective material

00:21:41on the front of the mirror.

00:21:43Most ice cream spoons

00:21:45come in different colors.

00:21:47This has nothing to do with aesthetics.

00:21:49The color indicates the size of the spoon.

00:21:51In this way, you can easily determine

00:21:53the number of spoons you will need

00:21:55to fill a kilogram.

00:21:57Wow, a sundae of a kilo!

00:21:59I want some, I want some, I want some!

00:22:01Some small tube caps are hollow on the top

00:22:03and have a small tip inside.

00:22:05Their goal is to break the aluminum

00:22:07that seals the tube.

00:22:09The cap fits perfectly into this hole

00:22:11and the tip is designed to break the seal.

00:22:13In this way, you don't need

00:22:15to tear off the small aluminum sheet

00:22:17with your fingers.

00:22:19The letter R in a circle

00:22:21on the packaging of a product

00:22:23means that the brand is officially deposited.

00:22:25Once this is done,

00:22:27the owner of the brand

00:22:29has the right to place this letter

00:22:31on all of its products.

00:22:33He can also sue anyone

00:22:35who tries to use his brand.

00:22:37This is a metal lock or hook

00:22:39on his wrist.

00:22:41It is a trigger lock.

00:22:43You can use it to lock the wrist

00:22:45in an open position.

00:22:47The fuel will then continue to be pumped

00:22:49even if you move away.

00:22:51In the past, coin coins

00:22:53had rather incongruous shapes

00:22:55or had no shape at all.

00:22:57The dishonest people used it

00:22:59to their advantage.

00:23:01They denied the precious metals

00:23:03from which the coins were made

00:23:05and were afraid of them.

00:23:07After that, it became easy

00:23:09to notice that a coin

00:23:11had been trafficked.

00:23:13The two holes in a sucker stick

00:23:15are there to hold the plug in place.

00:23:17When the stick is dipped in hot liquid syrup,

00:23:19it sinks into the holes

00:23:21and solidifies.

00:23:23Now, your candy is there to stay.

00:23:25The squares of fabric that go with the clothes

00:23:27are there so that you try

00:23:29cleaning products on them first.

00:23:31This way, you won't ruin

00:23:33when you decide to wash it.

00:23:35The holes in the back of the headphones

00:23:37allow the air to circulate in the speakers.

00:23:39This increases the bass frequencies,

00:23:41making the bass sound deeper.

00:23:43The sound quality also

00:23:45becomes much better.

00:23:47Am I not a great voice? Thank you!

00:23:49You can adjust your stapler

00:23:51so that it only staples the documents together temporarily.

00:23:53To do this, just rotate

00:23:55the clamping area.

00:23:57Most staplers have two options for this.

00:23:59One is standard,

00:24:01but the other allows you to fold the staplers

00:24:03by moving them away from the center.

00:24:05Later, when you don't need them anymore,

00:24:07you can easily remove them by hand.

00:24:09If you store peanut butter cans upside down,

00:24:11the oil will move to the bottom

00:24:13and all the solids will be on top.

00:24:15Don't laugh,

00:24:17it's very important for some people.

00:24:19The construction site workers

00:24:21and the laundry

00:24:23are usually dressed in orange

00:24:25because this color is visible even in bad weather.

00:24:27It is the most effective color

00:24:29to draw attention and alert people.

00:24:31No wonder that many security vests

00:24:33and warning cones are also orange.

00:24:35The stop sign has an eight-sided shape

00:24:37to help drivers recognize it easily,

00:24:39even if they see it from behind.

00:24:41And when the signs were not yet reflective,

00:24:43the octagonal shape

00:24:45prevented drivers from confusing the stop sign

00:24:47with any other at night.

00:24:49The rugged strips on the sides of the road

00:24:51are placed there to alert drivers

00:24:53who rush to the steering wheel.

00:24:55When the tires pass on these strips,

00:24:57the vibration works like an alarm.

00:24:59There are magnetic locks

00:25:01on the fuel pumps in gas stations

00:25:03in case someone leaves

00:25:05with the gasoline gun

00:25:07still attached to his tank.

00:25:09In this case, the lock automatically

00:25:11detaches the hose.

00:25:13The gasoline forms a rainbow in a puddle of water

00:25:15because it cannot mix with the water.

00:25:17It forms a thin membrane on top.

00:25:19When the light reflects on it

00:25:21and on the water at the same time,

00:25:23you get a rainbow.

00:25:25The triple handle of a jerry can

00:25:27is there to allow two people

00:25:29to carry it more easily

00:25:31and to distribute the liquid evenly.

00:25:33Gas canisters often have a second hole

00:25:35that must also be opened

00:25:37before pouring the liquid.

00:25:39Air passage will prevent it from overflowing

00:25:41and therefore from wasting it.

00:25:43Most gas canisters

00:25:45have two holes with caps,

00:25:47one larger and one smaller.

00:25:49You are supposed to open the smallest hole

00:25:51before pouring the liquid

00:25:53so that the liquid can stick

00:25:55and spread on your clothes and on the floor.

00:25:57Another little trick that we often neglect

00:25:59is the tip of the cap of an ointment.

00:26:01Most tubes are usually sealed

00:26:03with a plastic film or an aluminum sheet

00:26:05and opening it with your nails

00:26:07is not the best idea.

00:26:09The tip on the cap makes it easy

00:26:11to open even the most tightly sealed tube.

00:26:13You can use most screwdrivers

00:26:15with a wrench

00:26:17to create more cuts.

00:26:19Just place the wrench

00:26:21so that you will need to apply

00:26:23much less force than usual.

00:26:25You will also be able to reach

00:26:27difficult areas more easily.

00:26:29Cameras are installed in shops,

00:26:31banks and hospitals to monitor everything.

00:26:33If something happens,

00:26:35you can call the police or the ambulance.

00:26:37The camera helps to resolve a lot of cases.

00:26:39So why aren't there cameras

00:26:41in planes?

00:26:43The crew keeps order in the plane

00:26:45but they can't do anything

00:26:47if something serious happens.

00:26:49There is nowhere to hide in a plane.

00:26:51During the flight,

00:26:53the cameras are useless.

00:26:55And after the flight,

00:26:57the passengers' testimonials

00:26:59work as well as the cameras.

00:27:01So if the cameras are useless,

00:27:03why spend money on them?

00:27:05Water is very easy to clean

00:27:07because it has triangular molecules

00:27:09made up of an oxygen atom

00:27:11and two hydrogen atoms,

00:27:13hence the H2O.

00:27:15These molecules have slightly different charges

00:27:17that's why water easily attaches

00:27:19to other molecules,

00:27:21including those that make up saline.

00:27:23Many individual houses

00:27:25have triangular roofs

00:27:27because it allows rain,

00:27:29snow and dead leaves

00:27:31to slip on the door.

00:27:33If all these things pile up

00:27:35on the roof of your house,

00:27:37one day it could collapse.

00:27:39When a storm approaches,

00:27:41the clouds seem to become dark.

00:27:43But it's only an illusion.

00:27:45All the colors of the spectrum are bright.

00:27:47This makes us perceive the clouds as being white.

00:27:49The thicker the clouds are

00:27:51and contain droplets of water,

00:27:53the less they let the light through

00:27:55and the darker they seem.

00:27:57A good handful of doors

00:27:59are made of brass, bronze

00:28:01or some alloys of copper.

00:28:03These metals have an anti-germ effect.

00:28:05Bacteria spread much more slowly on them.

00:28:07They also get rid of the microbes

00:28:09quite quickly, in a few hours.

00:28:11But that doesn't mean

00:28:13you shouldn't wash your hands.

00:28:15Diamonds have symmetrical shapes

00:28:17to show you their brilliance.

00:28:19At first, these precious stones

00:28:21are not so beautiful.

00:28:23They go through several stages of size

00:28:25and then become elegant pieces.

00:28:27Most of these stones have a round shape

00:28:29with slightly pointed corners.

00:28:31It is in this shape that diamonds shine the most.

00:28:33Why are there two holes

00:28:35in an electric socket?

00:28:37The left hole is negatively charged,

00:28:39the right hole is positively charged

00:28:41and the space below is the ground.

00:28:43Electricity must flow through the circuit.

00:28:45The current goes through the positive hole,

00:28:47through the charger of your phone,

00:28:49for example,

00:28:51and then through the negative hole.

00:28:53Have you ever wondered

00:28:55what the small pocket of your jeans was for?

00:28:57People used to wear buttoned-up watches.

00:28:59The small pocket was designed for this purpose.

00:29:01Today, no one wears this kind of watch anymore,

00:29:03but the pocket is still there.

00:29:05And you can slip small objects in it,

00:29:07like a ring.

00:29:09They look a bit like air lamps,

00:29:11but they don't have bulbs.

00:29:13Their official name is

00:29:15Smoking Pipe,

00:29:17and they are part of history today.

00:29:19But they were very useful in the 19th century.

00:29:21These hollow pots

00:29:23evacuated the air

00:29:25and bad-smelling explosives

00:29:27to avoid, let's say,

00:29:29undesirable consequences.

00:29:31Most kitchen scissors

00:29:33have metallic teeth

00:29:35resembling pliers in the middle

00:29:37of a crab shell and other hard objects.

00:29:39You can also use them

00:29:41to open jars and bottles

00:29:43or to remove grass stems.

00:29:45Leather often looks dull to the eye

00:29:47because it is covered with tiny scratches and scratches.

00:29:49They scatter the light

00:29:51that hits the material.

00:29:53When you put on your shoes with a layer of wax,

00:29:55you fill these tiny crevasses.

00:29:57The surface becomes smoother

00:29:59and the rays of light bounce back

00:30:01more uniformly.

00:30:03This is why leather

00:30:05is filled with a special semi-transparent fluorescent ink

00:30:07that can shine

00:30:09in low light.

00:30:11Yellow and light green colors are the most popular

00:30:13because they don't prevent you from seeing the text

00:30:15after a photocopy in black and white.

00:30:17Photocopiers perceive

00:30:19yellow and light green marks as very pale

00:30:21and don't print them.

00:30:23Magnets are made in the shape of horseshoes

00:30:25because it increases the magnetic force.

00:30:27Colors are also important.

00:30:29The blue part indicates the south pole

00:30:31and the red part the north pole.

00:30:33The two poles work simultaneously

00:30:35and increase the attraction force.

00:30:37The 1 cm diameter hole

00:30:39in the doors of an elevator

00:30:41is a lock.

00:30:43If the doors are locked,

00:30:45an operator can manually open them

00:30:47by inserting a special key into the hole.

00:30:49As for the tiny holes

00:30:51in the plane's windscreens,

00:30:53they are there to balance the air pressure.

00:30:55The windscreen is made of three layers.

00:30:57The exterior glass is extremely solid.

00:30:59It can withstand

00:31:01the difference in air pressure

00:31:03during take-off and landing.

00:31:05The interior glass, which is the closest to you,

00:31:07is made of less expensive materials.

00:31:09It avoids any potential damage

00:31:11to the window.

00:31:13The hole itself is in the central glass.

00:31:15It not only balances the pressure

00:31:17but also avoids the window from jamming.

00:31:19The mechanical stairs brushes

00:31:21are there for your safety.

00:31:23They prevent you from getting too close

00:31:25to the edge of the elevator.

00:31:27So your clothes or laces

00:31:29don't get dirty.

00:31:31You see the sun in yellow or orange

00:31:33because the atmosphere of our planet

00:31:35is dispersed by colors like blue,

00:31:37green and purple.

00:31:39That's also why the sun looks

00:31:41warmer at sunrise and sunset.

00:31:43If you go to a store to buy oranges,

00:31:45you will surely find them in a red net.

00:31:47It's pure marketing.

00:31:49And this color is not a random choice.

00:31:51When they are wrapped

00:31:53in a red mesh net,

00:31:55the oranges look more orange,

00:31:57so you are more likely to buy them.

00:31:59Lemons are generally sold

00:32:01in green mesh nets

00:32:03for the same reason.

00:32:05If they were wrapped in red,

00:32:07they would look more orange.

00:32:09Green goes better with yellow

00:32:11and makes the color of the lemons stand out more.

00:32:13Mattress manufacturers

00:32:15produce a limited number of different mattresses

00:32:17and the only way to make them different

00:32:19is to invent a fantasy sewing pattern.

00:32:21Two mattresses from two different companies

00:32:23can be of exactly the same quality

00:32:25but cost a different price.

00:32:27Most people will never know

00:32:29and will believe that different patterns

00:32:31indicate a different quality.

00:32:33So when you buy,

00:32:35don't worry about the pattern.

00:32:37Almost all hotels have white bed sheets.

00:32:39They choose this color specifically

00:32:41to show how high their standards of cleanliness are.

00:32:43The whiter the sheets are,

00:32:45the more the hotel looks high-end.

00:32:47It is much easier to see dirt

00:32:49and stains on white laundry.

00:32:51It's a proof that your room has been made.

00:32:53More than 40 billion Oreo biscuits

00:32:55are made each year.

00:32:57It is the most popular industrial biscuit in the world.

00:32:59The geometric pattern

00:33:01stamped on these biscuits

00:33:03is the Nabisco logo,

00:33:05a symbol of European quality

00:33:07that encircles the word Oreo.

00:33:09It was in 1952 that William Turnier

00:33:11created the chocolate biscuit design

00:33:13that we know today.

00:33:15Wireless headphones could soon belong to the past

00:33:17because of wireless technology.

00:33:19But if you still have some,

00:33:21you may have noticed the rings

00:33:23on the headphones.

00:33:25One ring symbolizes a mono sound,

00:33:27two rings symbolize a stereo sound,

00:33:29and three rings mean you have a stereo sound

00:33:31and an integrated microphone.

00:33:33The iconic rings orange,

00:33:35red, purple, yellow and lime green

00:33:37of the Froot Loops cereals

00:33:39hide a secret.

00:33:41They do not represent different fruit flavors.

00:33:43All these rings have the same fruit flavors

00:33:45mixed together.

00:33:47The colors are just there to make it pretty.

00:33:49The Dell logo is tilted

00:33:51because the founder, Michael Dell,

00:33:53wanted his technology to reverse the world.

00:33:55A compass uses magnets

00:33:57to point to the magnetic north,

00:33:59but it is not exactly the geographic north.

00:34:01The north pole of the magnet of a compass

00:34:03points to the north

00:34:05because the north and the south are attracted.

00:34:07The magnetic south pole of the earth

00:34:09is close to the geographic north,

00:34:11while the magnetic north pole

00:34:13is close to the geographic south of the earth.

00:34:15Confusing, isn't it?

00:34:17The red spots you sometimes see

00:34:19after breaking an egg

00:34:21should not worry you.

00:34:23The tiny bloodstains

00:34:25can be caused by a small rupture

00:34:27of a chicken's blood vessel

00:34:29while it laid the egg.

00:34:31Eggs with these bloodstains

00:34:33can be eaten without danger,

00:34:35but you can remove this stain if you wish.

00:34:37It will not affect the taste of the egg.

00:34:39Ketchup is a word from many cultures,

00:34:41including China, Malaysia and Indonesia.

00:34:43It originally meant a marinated fish sauce.

00:34:45It is an acceptable spelling

00:34:47even though ketchup

00:34:49is the most popular spelling

00:34:51today.

00:34:53The AirBnB logo

00:34:55is not a folded trombone

00:34:57as it may seem at first glance.

00:34:59The BELO, as it is called for belonging,

00:35:01means more than that

00:35:03since it contains the face of a person,

00:35:05the symbol of location

00:35:07and a heart for love.

00:35:09All together, it forms the emblematic A

00:35:11of AirBnB and the symbol of conviviality.

00:35:13Red wine, or natural red 4,

00:35:15a.k.a. carmine,

00:35:17is made from tiny beetles.

00:35:19It has been used to colour many things,

00:35:21from cakes to sweets,

00:35:23to drinks.

00:35:25This shine on sweets

00:35:27also comes from insects.

00:35:29This time, it is the female

00:35:31of the Keria lacca tick.

00:35:33This coleopterus leaves behind

00:35:35a substance that is scratched on trees

00:35:37to be transformed into dried gum

00:35:39which gives it this shiny look.

00:35:41It is a panda wheel.

00:35:43The name Firefox

00:35:45is the English translation of its Chinese name.

00:35:47The sewer covers in the street

00:35:49are round for safety reasons.

00:35:51In past civilizations,

00:35:53such as Ancient Rome,

00:35:55the sewer covers were square-shaped stone plates.

00:35:57Unfortunately, they were prone to accidents.

00:35:59If they were not placed correctly,

00:36:01a square cover could slide

00:36:03diagonally into the hole.

00:36:05The generalization of round covers

00:36:07eliminated this problem

00:36:09The tomato is technically not a vegetable,

00:36:11but a fruit.

00:36:13Bananas are not related to palm trees

00:36:15or trees.

00:36:17They are herbs.

00:36:19Bananas are considered a herb

00:36:21because they never develop a line

00:36:23like a tree does.

00:36:25Instead, they form a succulent stem,

00:36:27such as citronelle

00:36:29or its cousin, ginger.

00:36:31They can also be considered berries.

00:36:33The colour of the Golden Gate Bridge

00:36:35was not supposed to be the orange-red

00:36:37that it is today.

00:36:39Many other original colours were suggested,

00:36:41such as black with yellow stripes

00:36:43or even the sugar-orange motif

00:36:45to make it visible for ships and planes

00:36:47especially in the frequent fog of San Francisco.

00:36:49But when the steel arrived,

00:36:51covered with an orange coating

00:36:53to protect it from rust,

00:36:55the architect preferred the colour

00:36:57International Orange

00:36:59and it remained.

00:37:01The pads at the back of the keyboards

00:37:03are not designed to relieve your wrists.

00:37:05They are designed to help you

00:37:07see letters and numbers better

00:37:09if you don't know how to type

00:37:11with your eyes closed.

00:37:13The colour of a pepper

00:37:15does not reveal anything

00:37:17about its taste or heat.

00:37:19In general, the smaller a pepper is,

00:37:21the stronger it will be.

00:37:23Heat does not come from seeds,

00:37:25but from white membranes

00:37:27that retain them.

00:37:29Hidden in the mountain's Toblerone logo

00:37:31is the image of a bear

00:37:33which is important for Bern,

00:37:35one of the largest cities in Switzerland

00:37:37where the founder created

00:37:39the famous triangular chocolate bar.

00:37:41Toblerone is also a pun

00:37:43on the founder's family name,

00:37:45Tobler, and the Italian word Torrone,

00:37:47which means a variety of nougat.

00:37:49The empty space under a cup of nougat

00:37:51is there to protect the nougat

00:37:53during transport.

00:37:55This technique is called

00:37:57an intermediate suspension.

00:37:59Not only are they better protected

00:38:01but also more efficient and faster.

00:38:03If you think that the hole

00:38:05on the body of a pen had no use,

00:38:07you're wrong.

00:38:09It's called an aeration system

00:38:11that helps the ink flow more easily.

00:38:13This way, the air pressure

00:38:15is balanced between the inside

00:38:17and the outside of the pen,

00:38:19which allows the ink to flow

00:38:21easily to the tip.

00:38:23One of the most recognized logos

00:38:25in the world of cycling

00:38:27has a hidden element.

00:38:29These metal supports

00:38:31on the top of the pistols

00:38:33have a unique design

00:38:35and a very precise function.

00:38:37If a distracted driver

00:38:39forgets that the pistol

00:38:41is still inside his tank

00:38:43and starts to ride,

00:38:45the magnetic supports separate

00:38:47without damaging any part

00:38:49of the fuel pump.

00:38:51The Wendy's logo pays homage

00:38:53to the daughter of the creator

00:38:55Dave Thomas.

00:38:57Although it was not intentional,

00:38:59it has become a trademark

00:39:01of the chain of restaurants.

00:39:03Finding the right road

00:39:05to get out of the highway

00:39:07can be sometimes confusing,

00:39:09especially in a foreign country.

00:39:11Be careful where the exit signs

00:39:13are on the side of the road.

00:39:15It will be the road

00:39:17where you will have to find yourself.

00:39:19Some dentifrices are equipped

00:39:21with a small operculum

00:39:23that must be removed

00:39:25in order to be used.

00:39:27The tostitos chips

00:39:29have a hidden symbol

00:39:31in the middle of their logo.

00:39:33The two T's in the middle

00:39:35look like two people

00:39:37eating tostitos

00:39:39around a bowl of sauce.

00:39:41One of the most emblematic monuments

00:39:43in the world,

00:39:45the Statue of Liberty,

00:39:47worked for 16 years

00:39:49as an entirely operational lighthouse.

00:39:51However, the light was barely visible

00:39:53in 1901.

00:39:55In 1901, it was finally put

00:39:57out of service as a lighthouse.

00:39:59Tourists could even visit the torch

00:40:01to have an impregnable view

00:40:03of the city.

00:40:05But an accident damaged

00:40:07the torch in 1916

00:40:09and it has been closed to the public

00:40:11since then.

00:40:13The label,

00:40:15do not remove under penalty

00:40:17of judicial prosecution,

00:40:19on the mattresses,

00:40:21animal fur,

00:40:23old hospital beds

00:40:25or clothes.

00:40:27Strict laws gave birth

00:40:29to these labels

00:40:31to prevent recycled materials

00:40:33from being reused

00:40:35and sold as new.

00:40:37The Toyota logo

00:40:39is more than a simple

00:40:41random combination of circles.

00:40:43The three overlapping ovals

00:40:45symbolize the fusion

00:40:47of customers' hearts

00:40:49with the hearts of crabs.

00:40:51However, it is not crab meat at all.

00:40:53Surimi is an imitation of crab meat.

00:40:55It is made of white fish

00:40:57mixed with sugar

00:40:59instead of crustaceans.

00:41:01The fish mixture is then heated

00:41:03and pressed to shape it.

00:41:05The Beats logo

00:41:07is simply a tiny B

00:41:09inside a red circle.

00:41:11The circle represents

00:41:13a human head

00:41:15and the B

00:41:17is a painted black mesh

00:41:19that is put on the windshield

00:41:21during manufacturing.

00:41:23It blocks ultraviolet rays

00:41:25and helps to distribute the temperatures

00:41:27between the metal and the glass.

00:41:29There are 24 symbols

00:41:31hidden in the Unilever logo.

00:41:33A sun, a dove, a plant,

00:41:35a spark, a pepper,

00:41:37a spoon, a bowl,

00:41:39a flower, an ice cream,

00:41:41a hand, hair, lips,

00:41:43a whirlwind, a fish,

00:41:45a particle, a packaging,

00:41:47a transformation, waves,

00:41:49a DNA sample, palm trees,

00:41:51a heart and the recycling symbol.

00:41:53They are supposed to represent

00:41:55the company's values and products.

00:41:57The hair clips are designed

00:41:59so that the zigzag part

00:42:01is placed on your scalp

00:42:03and not the flat part.

00:42:05This gives a better grip

00:42:07on the hair and skin

00:42:09which keeps the clip in place longer.

00:42:11Do you want to change your photos?

00:42:13Click on the album,

00:42:25If you have switched to iOS 14,

00:42:27the Meteo app can display

00:42:29the air quality index

00:42:31for certain cities in the world.

00:42:33So if you live in New York or London,

00:42:35you can check if the air quality

00:42:37is good today.

00:42:39The Meteo app also has other updates.

00:42:41It has a minute-by-minute forecast

00:42:43of the intensity of rain or snow

00:42:45in the next hour.

00:42:47However, this only works

00:42:49for the United States.

00:42:51If you live in the United States,

00:42:53Europe, Japan, Canada or Australia,

00:42:55you can receive alerts

00:42:57for any serious weather conditions

00:42:59like tornadoes, storms or floods.

00:43:01If you live in a very cold place

00:43:03and your iPhone turns off

00:43:05every time it freezes outside,

00:43:07go to Settings, Battery

00:43:09and check the battery status.

00:43:11If it is below 85%,

00:43:13you should probably change it.

00:43:15iOS 14 apps

00:43:17can be merged together.

00:44:23but once you're done,

00:44:25you can copy the text

00:44:27and paste it wherever you want.

00:44:29You can even use it to instantly

00:44:31translate text like foreign language menus,

00:44:33warning signs and instructions.

00:44:35Even if you're on iOS 14,

00:44:37you can still choose

00:44:39the alarm clock by simply

00:44:41dragging the numbers

00:44:43instead of composing them.

00:44:45If your mobile data isn't that good,

00:44:47the airplane mode can be useful.

00:44:49Turn it on and wait 5 to 10 seconds

00:44:51to find a better internet connection.

00:44:53If you're on 3G,

00:44:55it will become LTE.

00:45:43by simply sliding to the left.

00:45:45The same trick works

00:45:47when you're composing a phone number.

00:45:49So if you've clicked on the wrong number,

00:45:51you just have to slide it to delete it.

00:45:53With iOS 14,

00:45:55you don't have to waste time

00:45:57creating folders for your apps.

00:45:59There's an app library for that.

00:46:01It automatically lists

00:46:03all the apps you're using.

00:46:05The Updates section

00:46:07contains the apps you've recently downloaded

00:46:09and displays the apps you've recently launched.

00:46:57or a brand new iPhone 12.

00:46:59The improved QR reader

00:47:01for iOS 14 can scan

00:47:03almost any code,

00:47:05even if it's tiny or wrapped around an object.

00:48:13from your lock screen.

00:48:15You won't be able to scroll like a zombie

00:48:17at 4 a.m.

00:48:19You can easily improve

00:48:21the battery life.

00:48:23First, limit the use of widgets.

00:48:25Try not to add too many

00:48:27and limit the use of those

00:48:29that require a lot of data to stay up to date.

00:48:31You can also automate

00:48:33the low consumption mode

00:48:35up to a certain percentage of the battery.

00:48:37Go to Automation,

00:48:39click on the Plus button

00:48:41and create a new automation parameter.

00:48:43All right,

00:48:45this one is for all iPhone users

00:48:47who like to be on their couch.

00:48:49You can now send a voice message

00:48:51with the help of your good friend Siri.

00:48:53Just say,

00:48:55Hey Siri, send a voice message

00:48:57to Paul Dubois.

00:48:59Siri starts recording,

00:49:01stops when you're done

00:49:03and gives you a preview.

00:49:05All you have to do is click the Send button.

00:49:13the temperature of its color

00:49:15throughout the day,

00:49:17which gives it a more in-depth look

00:49:19with nature.

00:49:21Another interesting feature

00:49:23is facial recognition.

00:49:25It can even recognize a person

00:49:27through a Judas if it is recorded

00:49:29as a person in your photos.

00:49:31eMessage has also been updated.

00:49:33You can now pin up to 9 lines of messages

00:49:35so that the contacts you use

00:49:37most frequently

00:49:39are 24 hours out of 24,

00:49:417 days out of 7.

00:49:43You can also mention people

00:49:45in conversations to send a message

00:49:47to a particular person.

00:49:49eMessage also facilitates

00:49:51the filtering of unknown expeditors.

00:49:53The Let me know section

00:49:55in the messages

00:49:57allows you to receive notifications

00:49:59in the messages every time

00:50:01your name is mentioned,

00:50:03even if you have cut off

00:50:05the sound of the conversation.

00:50:07You won't miss any important messages,

00:50:09but you won't have to filter tons of messages

00:50:11that are not meant for you.

00:50:13As for the new features

00:50:15of eMessage,

00:50:17emojis have also received

00:50:19a brand new update.

00:50:21I'm talking about 11 new hairstyles

00:50:23and 19 new hairstyles

00:50:25to customize your emojis.

00:50:27You can send hugs

00:50:29and blush with brand new stickers.

00:50:31The jiggle mode

00:50:33has also changed.

00:50:35To log in to iOS 14,

00:50:37press your finger on an empty space

00:50:39on your screen, and voila!

00:50:41All the icons in the app

00:50:43start moving.

00:50:45In this mode,

00:50:47you can delete an app

00:50:49or move it to the library

00:50:51by simply clicking on the little minus sign.

00:50:53To leave the jiggle mode,

00:50:55touch an empty space

00:50:57or click on the big circular button

00:50:59at the bottom.

00:51:01This mode can also help you

00:51:03organize your e-mails.

00:51:05Press the little bar

00:51:07with dots at the bottom

00:51:09and you'll see a screen

00:51:11with all your pages displayed separately.

00:51:13Uncheck the pages you want to hide,

00:51:15press Finish, and voila!

00:51:17To retrieve one of these pages,

00:51:19do the same thing

00:51:21but uncheck the page you need.

00:51:23Supermarket trucks

00:51:25have a loop for a good reason.

00:51:27You don't want to leave your jacket

00:51:29in your truck

00:51:31because it's made to help you

00:51:33organize your truck.

00:51:35They also have another storage area

00:51:37at the bottom.

00:51:39When your truck is full,

00:51:41just lift this part

00:51:43and put a small basket

00:51:45for additional shopping.

00:51:47Lift the metal rod,

00:51:49put your basket on the horizontal bar

00:51:51above the wheels,

00:51:53and secure it with these hooks.

00:51:55If you have parsley stuck between your teeth,

00:51:57try this trick.

00:51:59Make a knot.

00:52:01The stripes on the toothpaste

00:52:03can look a little strange.

00:52:05It's just a marketing trick.

00:52:07In the 70s,

00:52:09the leading toothpaste brand

00:52:11added blue stripes

00:52:13to indicate that its toothpaste

00:52:15had a double action.

00:52:17The white toothpaste pads

00:52:19work just as well.

00:52:21However, the blue hairs

00:52:23on your toothbrush

00:52:25are there for a good reason.

00:52:27Have you ever noticed

00:52:29this little hole below the pads?

00:52:31It's there to drain the water

00:52:33and prevents the pads from rusting.

00:52:35It's also a place

00:52:37where you can lubricate it.

00:52:39A drop of oil will open

00:52:41and close much more easily.

00:52:43These stops on the side

00:52:45of the currency coins

00:52:47are not there for nothing.

00:52:49Previously,

00:52:51the edges were planed

00:52:53and then melted

00:52:55to obtain a metal

00:52:57called an orange.

00:52:59Here's another method.

00:53:01First, cut the top and bottom.

00:53:03Make a notch on the side

00:53:05and pull to open it.

00:53:07This little metal operculum

00:53:09that you see at the orifice

00:53:11of your favorite cream

00:53:13is there for a reason.

00:53:15These tubes are usually sealed

00:53:17with aluminum foil.

00:53:19So unless you want

00:53:21to break your nails

00:53:23you won't find out

00:53:25if you've been drinking soda

00:53:27all your life.

00:53:29That's what keeps

00:53:31your drink tasty and fizzy.

00:53:33The cap keeps the liquid inside

00:53:35and the rubber disc

00:53:37keeps the gas inside

00:53:39until you drink it.

00:53:41If you use the blue part

00:53:43of your eraser

00:53:45to erase pencils,

00:53:47your notebooks will be

00:53:49surely full of holes.

00:53:51You'll need to make sure

00:53:53your eraser is thick enough.

00:53:55Hair clips will never stay in place

00:53:57if the waves are not on the right side.

00:53:59You should always

00:54:01have them facing your head.

00:54:03You still can't reach it?

00:54:05Put a bit of lacquer

00:54:07on your hair clip

00:54:09before putting it in your hair.

00:54:11Many bottles of wine

00:54:13have an indentation

00:54:15on their base.

00:54:17It's convenient

00:54:19if you can't reach it.

00:54:21These little coffee beans

00:54:23only need to be opened

00:54:25differently.

00:54:27Look how happy they are!

00:54:29Try to tear the packaging

00:54:31in the middle by opening it.

00:54:33No more sugar on your fingers,

00:54:35no more paper hanging around

00:54:37and your coffee is happier too.

00:54:39The cotton disc packaging

00:54:41has a string that allows you

00:54:43to hook it to a hook

00:54:45in your bathroom.

00:54:47That's it!

00:54:49Door handles are usually

00:54:51made of brass, bronze

00:54:53or copper alloy.

00:54:55Why? It's antibacterial

00:54:57so it prevents microbes from spreading.

00:54:59In a few hours,

00:55:01the bad microbes are gone.

00:55:03But don't forget to wash your hands

00:55:05anyway.

00:55:07Bottles have a long neck

00:55:09for a good reason.

00:55:11You should hold your neck

00:55:13and not the bottle

00:55:15The foot prevents your drink

00:55:17from overheating.

00:55:19Two zips is too much?

00:55:21Maybe, but it's very useful

00:55:23against theft.

00:55:25You just have to lock them together.

00:55:27No one can open your bag.

00:55:29You don't have a lock with you?

00:55:31You can also assemble them

00:55:33with a string or a trombone

00:55:35or anything that can prevent

00:55:37pickpockets from succeeding.

00:55:39This little button at your neck

00:55:41on your shirt

00:55:43is for your client.

00:55:45So most running shoes

00:55:47now have a pre-installed

00:55:49anti-bubble system.

00:55:51It may seem a bit exaggerated

00:55:53but it's actually the extra hole

00:55:55at the top of your shoes.

00:55:57Put your lace in the extra hole

00:55:59by inserting the lace backwards.

00:56:01Cross them and put them through

00:56:03the loops.

00:56:05Now make your little knot

00:56:07as usual and run!

00:56:09If you find small bags of silica gel

00:56:11in excess, as soon as your shoes

00:56:13are a bit soaked, put a few

00:56:15packets of gel in them and leave them

00:56:17overnight.

00:56:19You may be using your shampoo

00:56:21badly lately. Here's a tip.

00:56:23Don't apply it all over your hair

00:56:25but only on the roots.

00:56:27The created foam will flow

00:56:29along your hair.

00:56:31The marks left in the notebooks

00:56:33are not made to take extra notes

00:56:35or to practice making emojis.

00:56:37They were invented to protect

00:56:39the environment.

00:56:41Previously, we lived among

00:56:43many hungry rats.

00:56:45They devoured the paper.

00:56:47So we put these marks so that

00:56:49people remember to start

00:56:51their work from the marks

00:56:53so that they are not lost

00:56:55devoured by a rat.

00:56:57American goblets, called

00:56:59solo cups, are a key element

00:57:01for any party.

00:57:03But they also have the advantage

00:57:05of being a green-doser

00:57:07and can hold up to

00:57:09355 milliliters.

00:57:11If you like to put milk in your tea,

00:57:13try this trick next time.

00:57:15Pour it by putting the hole up.

00:57:17It will splash a lot less

00:57:19and it's easier to control.

00:57:21The headrests are quite comfortable

00:57:23and the detachable ones are there

00:57:25for your safety.

00:57:27If you remove the headrest,

00:57:29you will see two solid metal bars.

00:57:31If you are stuck or locked in a car,

00:57:33you can always remove the bars

00:57:35The buttons on women's shirts are on the left,

00:57:37even if 85% of people are right-handed.

00:57:39It would be more logical to put them

00:57:41on the right.

00:57:43In fact, at the time,

00:57:45wealthy women had housekeepers

00:57:47to help them get dressed.

00:57:49So for her, having the buttons

00:57:51on the left was easier.

00:57:53The little tab on your rearview mirror

00:57:55has a real function.

00:57:57You can hang your deodorant,

00:57:59a big stuffed dog,

00:58:01maybe an emoji.

00:58:03If the night falls,

00:58:05this tab allows you not to be blinded

00:58:07by the car lights behind you.

00:58:09The McFlurry spoon has a square handle.

00:58:11It is directly attached to the machine

00:58:13that makes the ice cream

00:58:15after the sauce and the garnish have been poured.

00:58:17The spoon allows you to mix them

00:58:19directly in your skin.

00:58:21This saves time for employees

00:58:23and it saves water because they do not need

00:58:25to clean the machine after each use.

00:58:27The wooden belts are so top-notch

00:58:29right now.

00:58:31They are more aesthetic and much more natural

00:58:33than the others.

00:58:35But there is also a good reason to use them.

00:58:37They are made of cedar,

00:58:39a natural repulsive against mites.

00:58:41Little bonus,

00:58:43put dried orange peels in your closet.

00:58:45No more mites will come

00:58:47and read at home.

00:58:49Pockets are generally placed

00:58:51on the left side of shirts

00:58:53because most people are right-handed.

00:58:55Is it a myth or a reality?

00:58:57It's a reality.

00:58:59The pockets are made for right-handed people.

00:59:01Left-handed people know it well.

00:59:03For example, in public transport.

00:59:05Have you ever noticed that the scanner

00:59:07that validates your transport title

00:59:09is generally on the right side?

00:59:11And it's the same for everyday objects

00:59:13and household appliances.

00:59:15Chisels, tweezers, bottle openers

00:59:17and many other items of the same type

00:59:19are primarily designed for right-handed people.

00:59:21So it's the same

00:59:23for shirt pockets.

00:59:25Although some people use their two hands

00:59:27differently or change their preference

00:59:29according to the task to be accomplished,

00:59:31the vast majority of people are right-handed.

00:59:33According to a study,

00:59:3575 to 90% of the world population

00:59:37would be right-handed

00:59:39and 10% only left-handed.

00:59:41This means that having a pocket on the left

00:59:43rather than on the right

00:59:45is more convenient for most people.

00:59:47Do the experiment yourself.

00:59:49You have to make an effort to reach

00:59:51your pocket placed on the right side of your shirt.

00:59:53However, your gesture is quite natural

00:59:55when it comes to looking for something

00:59:57in your left pocket.

00:59:59Eating more protein

01:00:01allows you to have bigger muscles.

01:00:03What do you think?

01:00:05Myth or reality?

01:00:07It's a myth.

01:00:09It's true that eating protein

01:00:11is essential to have big muscles.

01:00:13Protein, in fact,

01:00:15are in a way the building blocks

01:00:17of your body.

01:00:19And yet, eating more than you need

01:00:21is completely useless.

01:00:23Everyone should drink

01:00:258 glasses of water a day.

01:00:27Do you think it's a myth or a reality?

01:00:29It's a myth.

01:00:31So don't blame yourself for drinking

01:00:33less water than recommended.

01:00:358 glasses is not a magical number.

01:00:37The need for hydration

01:00:39differs from person to person.

01:00:41The amount of water you drink every day

01:00:43depends on your activity

01:00:45and your physical habits.

01:00:47The temperature of the place you live

01:00:49also has an impact on your needs.

01:00:51You breathe more,

01:00:53so you have to drink more water.

01:00:55Soup, coffee, tea, fruit

01:00:57and other daily foods

01:00:59also contain water.

01:01:01Carrots are rich in sugar,

01:01:03so you should avoid eating them.

01:01:05If that's true,

01:01:07we should warn rabbits.

01:01:09What do you think?

01:01:11Myth or reality?

01:01:13It's a myth.

01:01:15Carrots contain about 85% water.

01:01:17Half a kilo of cooked carrots

01:01:19contain about 80% sugar.

01:01:21Compared to the amount of sugar

01:01:23in your favorite desserts,

01:01:25it's nothing.

01:01:27Carrots are rich in phytochemicals

01:01:29and eating them can help reduce

01:01:31your blood sugar.

01:01:33People in the Middle Ages

01:01:35thought the Earth was flat.

01:01:37Is it a myth or a reality?

01:01:39Obviously, the flat Earth is a myth,

01:01:41but the story built around it

01:01:43is also a myth.

01:01:45At that time,

01:01:47people made the same observations

01:01:49that we do today.

01:01:51For example, people in the Middle Ages

01:01:53could see, just like us,

01:01:55that the sun's rays,

01:01:57at sunrise and sunset,

01:01:59form an arc above the horizon.

01:02:01Vikings wore horn helmets.

01:02:03Is it a myth or a reality?

01:02:05The image is well known.

01:02:07No Viking warrior without his horn helmet.

01:02:09But in reality,

01:02:11there were no horns on their helmets.

01:02:13We have not found any proof of this.

01:02:15What purifies your body?

01:02:17Is it a reality or a myth?

01:02:19It's a myth.

01:02:21What we commonly call detox

01:02:23doesn't work like that.

01:02:25It's your internal organs

01:02:27that take care of your body's

01:02:29cleaning process.

01:02:31The rat, the liver, the kidneys,

01:02:33but especially the liver.

01:02:35Your body purifies itself

01:02:37permanently, naturally.

01:02:39No one needs to drink juices

01:02:41to eliminate these toxins.

01:02:43Is it a myth or a reality?

01:02:45You're right, it's a myth.

01:02:47Nuts are full of healthy fats.

01:02:49They are excellent for your heart

01:02:51and your other organs.

01:02:53On average, Americans throw

01:02:5538 kg of textile waste

01:02:57per year and per person.

01:02:59Is it a reality or a myth?

01:03:01A reality.

01:03:03Imagine all this waste.

01:03:05When a person throws away his clothes,

01:03:07they don't just go to waste.

01:03:09All these articles are sent

01:03:11to the recycling shops.

01:03:13It's much more ecological.

01:03:15You've probably heard

01:03:17about these miraculous laundry tips

01:03:19that make your clothes

01:03:21super clean and like new.

01:03:23What if these laundry tips

01:03:25were just myths?

01:03:27Here are three of them.

01:03:29Shirts must be buttoned

01:03:31when you put them in your machine.

01:03:33Is it true?

01:03:35It's a myth.

01:03:37It's better to keep the zipper closed

01:03:39but buttoning a shirt

01:03:41can dilate the buttonholes.

01:03:43In the long run, the buttons

01:03:45will start to slip and your shirt

01:03:47will be easy to throw away.

01:03:49Washing your clothes in hot water

01:03:51is the best way to clean them.

01:03:53Is it a myth or a reality?

01:03:55It's still a myth.

01:03:57You want to get rid of microbes in your clothes.

01:03:59However, hot water alone

01:04:01won't be enough.

01:04:03Nowadays, many detergents are perfectly

01:04:05able to clean our clothes

01:04:07in cold or warm water.

01:04:09We must clean the stains

01:04:11on the outside of the fabric.

01:04:13Is it true?

01:04:15Most people apply water and soap

01:04:17directly on the stain,

01:04:19starting with the outside of the fabric.

01:04:21But that's not the best solution.

01:04:23It's better to start with the inside.

01:04:25The stain can sink deeper

01:04:27if you treat it from the outside.

01:04:29Try to bring the stain up to the surface

01:04:31rather than pushing it

01:04:33inwards.

01:04:35Listening to music is effective

01:04:37to learn a new language.

01:04:39Is it a myth or a reality?

01:04:41It's a reality.

01:04:43Scientists have stated that listening to a song

01:04:45and humming along can help us

01:04:47learn a language.

01:04:49Many people have trouble learning

01:04:51grammar rules.

01:04:53However, in our daily lives,

01:04:55we don't always follow them.

01:04:57Songs can help us memorize

01:04:59common expressions.

01:05:01Scientists have also stated that music

01:05:03can help us remember new words

01:05:05and enrich our vocabulary.

01:05:07Let me give you an example.

01:05:09Do you remember your first year of school?

01:05:11Yes, the alphabet song.

01:05:13Are you a morning person

01:05:15or a night bird?

01:05:17In any case, you need to be aware

01:05:19of the realities and myths

01:05:21about sleep.

01:05:23A person managed to stay awake

01:05:25for 11 consecutive days.

01:05:27Do you think it's possible

01:05:29or is it an urban legend?

01:05:31Randy Gardner set the record

01:05:33for the longest sleep.

01:05:35It was a scientific experiment

01:05:37conducted by Dr. William C. Demond,

01:05:39who studied sleep

01:05:41at Stanford University.

01:05:43This doctor recorded and monitored

01:05:45Randy Gardner's sleep activity

01:05:47and Gardner managed to stay awake

01:05:49for 11 days and 25 minutes.

01:05:51Your body ends up getting used

01:05:53to less sleep.

01:05:55Myth or reality?

01:05:57It's a myth.

01:05:59Your body, and your brain in particular,

01:06:01can't get used to less sleep.

01:06:03Did you notice that after a few nights

01:06:05of insufficient sleep,

01:06:07you started to feel more sluggish during the day?

01:06:09It's your body that tries to adapt

01:06:11to its lack of rest.

01:06:13Long-term lack of sleep affects

01:06:15your performance, your concentration

01:06:17and your decision-making during the day.

01:06:19Many adults

01:06:21only need 5 hours of sleep

01:06:23or even less. Is it true?

01:06:25It's very easy.

01:06:27It's a myth.

01:06:29National Sleep Foundation experts

01:06:31recommend that adults sleep

01:06:33between 7 and 9 hours per night.

01:06:35Some people have a genetic mutation

01:06:37that allows them to wake up in full form

01:06:39after a short night of sleep.

01:06:41But these people are exceptions.

01:06:43One in four million.

01:06:45People who are able to sleep

01:06:47anywhere or at any time

01:06:49are said to be good sleepers.

01:06:51What do you think? Myth or reality?

01:06:53It's a myth.

01:06:55Good sleepers sleep enough

01:06:57and at regular hours.

01:06:59Cats spend two-thirds of their lives sleeping.

01:07:01Is it true?

01:07:03You probably won't be surprised.

01:07:05It's a reality.

01:07:07So, did you manage to answer

01:07:09most of these questions correctly?

01:07:13Well, grab your phone.

01:07:15Now, turn it around.

01:07:17Do you see this dot between the camera lens

01:07:19and the flash? It's a small microphone.

01:07:21I bet you didn't know what it was.

01:07:23What is it doing there?

01:07:25Well, when you're on the phone,

01:07:27this little hole reduces the background noise

01:07:29that the main microphone picks up

01:07:31while you're talking.

01:07:33Without it, your calls wouldn't be as clear

01:07:35as they are.

01:07:37You're lost in the woods

01:07:39and you're trying to find your friends.

01:07:41You suddenly remember that you have something

01:07:43that can help you.

01:07:45You grab one of the chest straps

01:07:47of your backpack and whistle in it.

01:07:49Yes, today many bags are equipped

01:07:51especially those made for the outside.

01:07:53And it doesn't last long.

01:07:55Very quickly, you hear the call of one of your friends

01:07:57and you follow him to the campfire

01:07:59saved by this object you never thought of.

01:08:01If you're curious,

01:08:03you may have already wondered

01:08:05what this little pocket in your jeans is for.

01:08:07You know, the one inside

01:08:09one of your front pockets.

01:08:11It's often used to store coins

01:08:13and bills, but that's not why it's made.

01:08:15Actually,

01:08:17it's designed to store your watch.

01:08:19Maybe that's where the term

01:08:21pocket watch comes from.

01:08:23You finally get home

01:08:25after a long day at work.

01:08:27You obviously don't want to cook,

01:08:29so you sit on the couch,

01:08:31you watch TV a little

01:08:33and you order a dish to take away.

01:08:35Chinese cuisine? Good idea.

01:08:37You ring the doorbell.

01:08:39It must be your meal.

01:08:41It smells deliciously good.

01:08:43Wait, before taking the plates,

01:08:45do this.

01:08:47Put them on the table.

01:08:49It's a perfect plate.

01:08:51And it's made of cardboard,

01:08:53so there's no dishes to do afterwards.

01:08:55The soda can you get with your meal

01:08:57also has a nice function.

01:08:59Look at the little metal tab,

01:09:01the one you use to open the can.

01:09:03Well, guess what?

01:09:05You can put your straw in it.

01:09:07Actually, that's exactly why it's made.

01:09:09Go ahead, try it.

01:09:11You won't be surprised

01:09:13that the letters on your keyboard

01:09:15are unique,

01:09:17and French keyboards

01:09:19are an exception.

01:09:21Here's an American keyboard,

01:09:23one of the most common.

01:09:25The keys are arranged

01:09:27according to what we call

01:09:29the QRT arrangement,

01:09:31so named because of the first

01:09:33six keys located under the numbers.

01:09:35It turns out that this has not

01:09:37always been the case.

01:09:39They used to be arranged

01:09:41alphabetically,

01:09:43but there were things called

01:09:45writing machines.

01:09:47You remember?

01:09:49You pressed a key,

01:09:51and a character bar

01:09:53would pop up to stamp

01:09:55a letter on a piece of paper.

01:09:57With time, the keyboards

01:09:59managed to write very quickly.

01:10:01Too quickly.

01:10:03The character bars would

01:10:05end up getting stuck

01:10:07in each other,

01:10:09which disrupted the process.

01:10:11The writing machine

01:10:13worked better because

01:10:15it made typing more difficult,

01:10:17which slowed down the typists

01:10:19and prevented the character bars

01:10:21from getting stuck.

01:10:23It's much better today,

01:10:25no more character bars,

01:10:27no more writing machines.

01:15:19Here is another little kitchen secret.

01:15:22The handle of a saucepan is often pierced with a hole.

01:15:25Most people use it to hook their saucepan to a hook as an easy storage method.

01:15:30But this hole has another use.

01:15:32When you cook, you can use this handle to put your wooden or plastic spoon.

01:15:37This allows you not to dirty your work plan when you put it down.

01:15:41Glass bottles are generally equipped with a cap.

01:15:44It's normal. Without that, the liquid would simply spread.

01:15:48In this cap, there is a plastic lining that apparently has no use.

01:15:53But it's false.

01:15:54It's a sealant seal.

01:15:56It is thanks to it that your drink remains sparkling.

01:15:59Ah, exactly the refreshment I needed.

01:16:03Many door handles are made of brass.

01:16:05And it's not by chance.

01:16:06They are made in this specific material because it is the worst enemy of bacteria.

01:16:11It's true, he destroyed them.

01:16:13Perfect for those who want to keep a clean house and avoid microbes.

01:16:16So, let's go fishing?

01:16:20How many hidden functions are there in your car that you have never heard of?

01:16:24Nowadays, most cars have a color code under their hood.

01:16:28It is thus much easier to know what you have to watch out for between two inspections.

01:16:33Like the gauge, the oil cap or the cooling liquid.

01:16:37You can even take a look at the brake fluid and the washing liquid.

01:16:41For everything that is black or gray, you have to leave it to the mechanics.

01:16:46Have you ever seen a snowflake-shaped light on the dashboard of your car?

01:16:51It is not there to warn you about the arrival of winter holidays.

01:16:54If that's what you think.

01:16:55It is actually a sensor that indicates the outside ambient temperature.

01:16:59It is activated and makes the indicator appear when there is a danger to the road due to a sudden drop in temperature.

01:17:08It sometimes happens that a sound warning or a message on your dashboard

01:17:11warns you that the roads may be covered in ice

01:17:15so that you can adjust your speed or change tires if necessary.

01:17:21Most cars are also equipped with special devices for the summer, such as sunshades.

01:17:26Yours may have an additional bonus that you might want to discover.

01:17:30We all know that they rotate to help the driver even when the sun does not shine from the front.

01:17:35But some of them can also deploy

01:17:38so that they can provide shade to a larger surface.

01:17:42If you see that yours is not extendable, there is a simple solution.

01:17:46Buy a sunshade extender. You can even find it online.

01:17:50It attaches to your sunshade or to your existing windows

01:17:54to provide better protection against the sun and better visibility.

01:17:58Let's discover some hidden features at home.

01:18:01It's not a wizard, but there is a bad way to make ice in the freezer.

01:18:06And that's because you probably don't use the freezer properly.

01:18:11They have this particular shape because you have to fill the freezer

01:18:14until there is a layer of water on top.

01:18:17This layer allows you to quickly remove the ice cubes from the freezer

01:18:21because they break when you twist them and let each ice cube out.

01:18:25You can then grab them at a glance and taste your drink.

01:18:30If you find that the heat in your oven is too high

01:18:33and you have to cook difficult dishes that require better temperature control,

01:18:37there is an easy way to adjust it.

01:18:41The buttons on your oven must be equipped with calibrating screws at the back.

01:18:45Remove the plastic button and adjust it according to your preferences.

01:18:49Make sure to unplug the oven from any power source before doing so.

01:18:54Do you know what your cook and your car have in common?

01:18:58They both have a hood that you can open if you need to take a look

01:19:02or if they need to be cleaned.

01:19:04If you look carefully at the top of your cooker,

01:19:07you will see two hinges located at the level of the rear edges.

01:19:11You can easily lift them and clean all the dirt that is stuck inside.

01:19:17Have you ever wondered why the glue does not stick inside the bottle?

01:19:21The answer is a little more complex depending on the type of glue,

01:19:25but the simple answer is that there is no air inside.

01:19:30PVA glue contains molecules called polymers and water.

01:19:35When the glue comes out, the water evaporates,

01:19:38leaving behind only the adhesive polymers.

01:19:41The situation is more or less the opposite with superglue.

01:19:45It contains a chemical product that solidifies as soon as it comes in contact

01:19:49with the water vapors present in the air.

01:19:52Did you know that Microsoft Word has a function that you can use

01:19:56for references and bibliography?

01:19:59This function is not only useful for keeping a track of everything,

01:20:02but it also automatically puts all the corresponding information on the page.

01:20:07If you like to surround yourself with lots of plants inside,

01:20:10here is a simple way to know if they need to be watered.

01:20:14Put your finger in the ground.

01:20:16This should give you a better idea than just looking at the surface of the plant.

01:20:20If you can penetrate 5 to 7 cm into the ground and you feel that it is dry,

01:20:25the plant probably needs to be watered.

01:20:28However, this trick works better with small plants in pots,

01:20:32because the depth is more limited.

01:20:34In any case, it is always preferable to look for the needs of the plant

01:20:38in terms of watering and sunlight before engaging in a project.

01:20:42And always be careful not to damage its roots.

01:20:47Be honest, there are clothes that you wear all the time

01:20:50and others that stay at the bottom of your closet and that you have probably forgotten.

01:20:55Here is an ingenious way to know which one is which.

01:20:58To begin with, you have to turn all your belts upside down.

01:21:03If you really want to invest in this project,

01:21:05you can put pieces of tape on the belts and write the starting date on each of them.

01:21:11After that, everything is quite simple.

01:21:15Every time you wear a particular garment, turn the belt so that it is turned forward.

01:21:21After six months or a year, all the items that have not yet been turned over

01:21:25must be donated or given to charity.

01:21:29Another good way to use the belts to help you organize your wardrobe

01:21:33is to use them for your scarves.

01:21:35They will no longer be crumpled, but you will also be able to see them much better

01:21:38and have a clear view of the scarves you are actually using

01:21:41and the ones you should drop.

01:21:45If you are looking to increase the storage space of your wardrobe,

01:21:48especially during the change of season,

01:21:50go and buy vacuum-packed storage bags.

01:21:54Then, all you have to do is fold your clothes or other pieces of clothing,

01:21:58such as sheets or blankets, for example, and place them in the bags.

01:22:04Turn on your vacuum cleaner, put the tip on the bag seal

01:22:08and remove all the excess air from the bag.

01:22:10This will allow you to reduce the storage size of your clothes

01:22:13and keep your clothes clean, dry and without mites.

01:22:17If you have an empty bag and you are not yet sure if you want to recycle it,

01:22:21you can always turn it into a lamp.

01:22:24The steel bags are the most appropriate for this.

01:22:28All you have to do is cut a small hole in the bottom of the bag

01:22:31and place a kit of lamps to hang in this place.

01:22:34You can even paint it by hand or with a pump if you need it to be a particular color.

01:22:40Another way to properly reuse objects in the house

01:22:44is to use biscuit jars to store drying balls,

01:22:47but there is no limit here.

01:22:51You can also use drying sheets to dust the screens of your house,

01:22:54such as those of computers, cell phones or televisions.

01:22:58These items are charged electrically

01:23:00and therefore generally attract a lot of dust particles.

01:23:04Drying sheets are designed to reduce static electricity adhesion,

01:23:08which not only eliminates dust,

01:23:11but also to keep it at a distance for a longer period of time.

01:23:15Drying sheets are also useful if you have a bad day with your hair,

01:23:19believe it or not.

01:23:21They can help you tame rebellious mites when your frizzles become uncontrollable.

01:23:26Pass one of these drying sheets from the root of your hair to the tip

01:23:30and you will be surprised.

01:23:33If you like the smell of a soap bar in particular

01:23:35and you want to find it on your clothes too,

01:23:37you can also take one of these bars to make a clothes cooler.

01:23:41Place it in a fabric and then put it anywhere between your clothes.

01:23:45Your shirts will smell wonderfully good every time you take them

01:23:49and you can also save on softening.

01:23:52I don't know what's wrong with your laundry,

01:23:54but mine loves to jump, I assure you.

01:23:57If yours tends to leave its place,

01:23:59especially during the intense drying cycles,

01:24:01it is because it is not perfectly fixed to the ground.

01:24:04The good news is that most modern laundry can self-level

01:24:08since they are equipped with a pair of feet.

01:24:11Just lift the back of the device from the surface on which it rests

01:24:14so that it drops them and locks them in place once perfectly leveled.

01:24:23The next time you follow a recipe

01:24:25where you have to separate the egg yolks from the whites, try this.

01:24:28Peel a clove of garlic and rub your fingers with it.

01:24:31Gently break an egg into a bowl.

01:24:33With your garlic fingers, pick up the egg yolk.

01:24:36And there you go, you can now marvel at the perfection

01:24:39with which it separates from the white.

01:24:42If you have to scale hard eggs, there are two simple ways to do it.

01:24:46When you boil them, add a teaspoon of baking soda to boiling water.

01:24:51This will make scaling much easier.

01:24:54You can also pass them under cold water as soon as they are cooked.

01:24:58The shells will come off much more easily.

01:25:01And you will not burn your hands by scaling them.

01:25:04The edges of the roads have rugged bands for a very important reason.

01:25:08Their main function is to alert the drivers who are lurking behind the wheel.

01:25:12When a car begins to deviate from the road,

01:25:15its tires pass on the bands and the noise wakes up the driver.

01:25:19Price tags or those that are glued to the tupperware

01:25:23are easier to remove than you think.

01:25:25No need to waste hot water and soap to try to take them off.

01:25:29Rather take a dry hair, blow hot air directly on the label for a minute or two.

01:25:35And there you go, the label will come off at once.

01:25:38White household appliances can turn yellow over time.

01:25:42To make them shine, use this simple trick.

01:25:45Apply discoloring cream to the surface.

01:25:48Then wrap the device in plastic and leave it like that all night.

01:25:53The next morning, it will be as white as when you bought it.

01:25:57Opening a can pack can be difficult.

01:26:00You will probably tear a hole in the plastic and try to extract a can.

01:26:05In reality, the bottom of the cans was designed to make this step much easier.

01:26:10Take an old can and rub it on top of a new can of the pack.

01:26:14A circle of the exact size of a can will be cut.

01:26:18In this way, you can easily remove the new can without tearing everything.

01:26:23Now let's move on to squeezing lemons.

01:26:26When you choose lemons, you never know how juicy they are.

01:26:30And often when you bring them home and squeeze them, almost no juice comes out.

01:26:35Heat these lemons in the microwave for 30 seconds before opening them.

01:26:40You will see that the juice will come out much more easily.

01:26:43But be careful, they will be hot and you don't want to burn your hands.

01:26:48If you want to listen to music but you don't have a speaker, there is a solution.

01:26:52Place your phone in a cup or bowl.

01:26:55The sound will be instantly amplified.

01:26:58If you don't have a belt to wear, but you still need to hang your shirt, this tip is for you.

01:27:04Most shirts have a tiny loop in the back between the shoulders.

01:27:09You can use it to hang your shirt.

01:27:12Now imagine this nightmare scenario.

01:27:15Your phone has no battery, but you are already late.

01:27:18In this case, activate airplane mode and your phone will charge 100% in no time.

01:27:24You can put the sticky part of a post-it on your laptop keyboard.

01:27:29This will help you remove the small pieces of food and dust that get stuck between the keys.

01:27:34Avoid putting very hot food in plastic containers.

01:27:38Hot plastic releases all kinds of toxic chemicals.

01:27:42And you don't want your food to absorb these substances, do you?

01:27:46What is more pleasant than a hot shower in the evening?

01:27:50The bubbles are not only pretty and fragrant, they also keep the hot water longer.

01:27:55So you can enjoy a long bath without it getting too cold.

01:27:59You go home with a craving for peanut butter and jam.

01:28:04Put your peanut butter with a layer of oil on top.

01:28:07To avoid this the next time, put your peanut butter pot upside down.

01:28:12Your screwdriver and your wrench can work together to remove any recalcitrant screw.

01:28:18Grab the handle of your screwdriver with the wrench and use it to apply more force.

01:28:24This method will also help you reach more difficult areas.

01:28:28There is a reason why your coffee spoon looks like a straw.

01:28:32It is pierced with holes because it reduces the amount of plastic that manufacturers use.

01:28:37In addition, they prevent the straw from floating.

01:28:40The holes are filled with coffee, which makes it heavier.

01:28:44Speaking of coffee, you should never buy a product that is over 18 months old.

01:28:49Make sure to look at the expiration date when you choose it.

01:28:53If you have ever had problems with classic salt and pepper, here is a tip.

01:28:58Instead of shaking your arm to try to get the salt out of the container,

01:29:02rub the bottom of one of the containers with the bottom of the other.

01:29:05Grab the salt shaker and hold it so that the bottom is turned down.

01:29:10Now, while holding the pepper shaker vertically,

01:29:13rub the two bottoms against each other, creating a circular friction.

01:29:17After that, you can pour salt effortlessly.

01:29:21After a long day of hiking, your shoes can have a funny smell.

01:29:25If this is the case, put dry tea bags inside your shoes

01:29:29and keep them in a dry place for a while.

01:29:32The tea bags will absorb the bad smells and make your shoes dry.

01:29:37If you broke the strap of your sandal while walking, there is a way to fix it.

01:29:42But only if you have a pair of pliers with you.

01:29:45First, put the strap back in its hole.

01:29:48Then, attach the clamp to the bottom of the strap.

01:29:51And that's it.

01:29:52Your body needs a daily amount of vitamin C to strengthen your immune system.

01:29:57But oranges are a difficult fruit to peel.

01:30:01To prevent the juice from being pulverized on your face,

01:30:04start by cutting the upper and lower parts of the orange.

01:30:08Then, cut the skin vertically,

01:30:11slip your fingers under the opposite sides of the cut and open your orange.

01:30:15If it is difficult for you to determine the amount of detergent you need

01:30:19to wash your clothes, here is a tip.

01:30:22Generally, detergent caps are accompanied by marks

01:30:26that indicate the exact amount of liquid you should use for washing.

01:30:30This will also allow your detergent to last longer.

01:30:34Indelible markers are not as indelible as you think.

01:30:38Let's say you used one, thinking it was an ordinary marker,

01:30:42to draw something on a whiteboard.

01:30:45Good news, your board is not marked forever.

01:30:48There is a way to save it.

01:30:50Take an ordinary marker and use it to draw over the lines

01:30:54left by the indelible marker.

01:30:56Let it rest for a moment so that the two markers mix.

01:31:00The ink of the ordinary marker contains a solvent

01:31:03that will dissolve the pigment contained in the indelible marker.

01:31:06Now take a paper towel and rub the board to clean it.

01:31:11The traces of the two markers will be easily removed.

01:31:14If you have to peel peaches, use the whitening technique.

01:31:18First, heat some water and wait for it to boil.

01:31:22Soak the peaches in the water for about 20 seconds,

01:31:25then place the fruits in a bowl with cold water

01:31:28and leave them for about 5 minutes.

01:31:31And there you go, the skin will come off much more easily.

01:31:34The plastic lid that covers your bowl can be used as an underglass.

01:31:39Remove the lid and place it on the table.

01:31:42The bottom of the bowl will fit perfectly into the inner ring of the lid.

01:31:47Finish the task on the table.

01:31:49The escalators are there for safety reasons.

01:31:53They remain stationary when the escalator is in motion,

01:31:56which prevents people from getting too close to the sides.

01:31:59This avoids accidents, such as stuck shoe laces.

01:32:03If you pay close attention to the elevator doors,

01:32:06you will notice that they have a small hole.

01:32:08It's a lock hole, and only the authorized staff has the key.

01:32:12They use it in case of emergency or when the device is being maintained.

01:32:17Well, I know it's a bit cold or touchy,

01:32:20especially during a cold winter day,

01:32:22but did you know that brass door handles are actually really useful?

01:32:26In addition to being elegant and shiny.

01:32:29As it is a copper alloy, brass has antimicrobial properties.

01:32:33This means that it can help eliminate germs and harmful bacteria,

01:32:37sometimes in less than two hours.

01:32:40In very busy places, it is even more useful.

01:32:43But since brass is much more expensive than other metals,

01:32:45such as nickel and steel,

01:32:47we no longer see many door handles of this type nowadays.

01:32:51Speaking of beautiful polyvalent objects,

01:32:53most screwdrivers have a little secret that is unique to them.

01:32:57From time to time, they can slip into a key

01:32:59to create more torque during torsion.

01:33:02Not to mention their usefulness when it comes to screws

01:33:05located in hard-to-reach places.

01:33:07There is a reason why women's button shirts

01:33:10are designed for left-handed people,

01:33:12and it has nothing to do with fashion.

01:33:14This practice dates back to the time

01:33:16when chambermaids helped ladies get dressed,

01:33:18and it was easier for them to accomplish their tasks with this orientation.

01:33:22The fact that buttons are placed this way

01:33:24was a sign of wealth.

01:33:26It is therefore easy to imagine why this practice has persisted,

01:33:29even if most people dress themselves nowadays.

01:33:33The next time you receive a package in your mailbox,

01:33:35take a look at the cutter.

01:33:37If it has diagonal lines on the blade,

01:33:39you will be able to benefit from a small advantage in terms of design.

01:33:43It turns out that these are blades that break.

01:33:45Continuously cutting cardboard can wear out the sharp edge of the blade.

01:33:49To avoid having to buy a brand new cutter,

01:33:52the upper segment of the next line can break

01:33:55to obtain a new super-sharp edge.

01:33:57To do this, look at the small hole at the base of the tool,

01:34:00sometimes called the blade breaker.

01:34:02The people who came up with this brilliant invention

01:34:05are engineers who were inspired by the way chocolate bars are divided.

01:34:09Wait a minute!

01:34:11Don't throw away this cardboard package right away.

01:34:13It is very likely that you have bags of silica gel somewhere at the bottom of the box.

01:34:18As this gel is a tool for drying,

01:34:21it absorbs the humidity of its environment

01:34:23so that you can keep these bags for other occasions.

01:34:26If you need to dry your phone

01:34:28or another electrical object,

01:34:30you can place it in a container next to the silica gel to reduce damage.

01:34:35You don't need to be a mechanic to know

01:34:37when the tires of a standard car need to be replaced

01:34:40because they are equipped with a well-designed indicator.

01:34:43If you look closer,

01:34:45you will see that the tire strips are made up of a pile of rubber notches.

01:34:49When the marks are equal to the perpendicular bars,

01:34:52this is the sign that you must make an appointment with your local car service

01:34:56because it is very likely that the tires have lost most of their traction

01:35:00and that they are no longer safe for driving.

01:35:03The upper corners of the windshield of a car

01:35:05have textured black dots integrated at the edge of the glass.

01:35:09This detail is not there for design reasons.

01:35:11It is a coated coating,

01:35:13which means that a special type of ceramic paint is added to the glass

01:35:17to protect its sealant from UV rays.

01:35:20It also allows you to conceal and create a coarser surface

01:35:24for the glue used to put the glass in place.

01:35:27Every time you hit the road,

01:35:29check if there is a small bar under the rearview mirror of your car.

01:35:32I bet you didn't know it was there

01:35:34to help switch the rearview mirror from day vision to night vision.

01:35:38It uses a prismatic glass technology

01:35:41to blur the reflection and reduce the glare of the headlights behind you in traffic.

01:35:46These manual-adjusted rearview mirrors were invented in the 1930s,

01:35:50but they became the norm in the 1970s.

01:35:54When you are in the car,

01:35:56take a look at the headrests,

01:35:58because you probably don't know that they have a hidden function.

01:36:01Of course, they can be adjusted to suit all sizes of passengers

01:36:04so that they benefit from adequate support for their heads and neck.

01:36:08The hidden feature is that they are detachable

01:36:11and have two very solid metal bars.

01:36:14If you ever get stuck in a car and have to flee quickly,

01:36:18these bars can be very useful to break the windows of the car.

01:36:22So, you're driving around and suddenly you run out of gas.

01:36:26What I'm going to describe to you looks more like a joke

01:36:29than a real situation that could happen.

01:36:32But what happens if you are in such a hurry

01:36:35that you accidentally leave with the gasoline gun still in the tank?

01:36:40Well, the guns were designed to avoid any risk.

01:36:43Don't worry, they have a separation device

01:36:46that allows the pipes to be detached when removed with sufficient force.

01:36:51Initially designed at the beginning of the 20th century

01:36:54to be worn exclusively by basketball players,

01:36:57sneakers have quickly become one of the essential elements of fashion,

01:37:01just like jeans and leather jackets.

01:37:04If you look at them closely,

01:37:06you will see that they have two additional holes on the side,

01:37:09similar to those of shoe laces.

01:37:11They are made like this not only to provide additional ventilation,

01:37:15but also to allow people to be more creative with their laces

01:37:18when they wear their shoes.

01:37:20Admit it, you always thought that the bars were united at one end

01:37:24in order to keep them together until you were ready to start your meal.

01:37:29This may not be quite true.

01:37:31If we look at them more closely,

01:37:33it turns out that these wooden tools have a square-shaped end.

01:37:37The bars made in this way

01:37:39are from an old Japanese traditional design

01:37:42that makes it easy to break the ends.

01:37:44The separated end can then be used as a support for the sticks

01:37:48in order to keep them cleaner,

01:37:50in the hope that they can be reused

01:37:52since they will not touch the table or any other surface.

01:37:56Women's bikes have a special design

01:37:59that surprisingly has a historical and fashionable function.

01:38:02The lower frame is largely intended to compensate

01:38:05for the generally smaller size of women

01:38:07compared to that of a normal man.

01:38:09If this is the case for the handlebars and the saddle,

01:38:12the general frame is lower for an additional reason.

01:38:15At the time when women wore long skirts and dresses all day,

01:38:18every day they had to make sure

01:38:20that their clothes would not get stuck in the frame.

01:38:23This is how we designed a bike with a lower frame

01:38:26perfectly adapted to women and their needs of the time.

01:38:29The fact that the toothpaste is multicolored

01:38:31is not only a nice advantage

01:38:33to make dental hygiene more fun.

01:38:35There is a secret explanation

01:38:37related to each of the colors

01:38:39dating back to the 1970s.

01:38:41At that time, people were increasingly interested

01:38:44in their oral health

01:38:46and were therefore looking for products

01:38:48that could do more than just brush their teeth.

01:38:51A company was the first to do this

01:38:53by adding a mouthwash to its toothpaste,

01:38:55that is, the blue strip.

01:38:57It then added the red strip

01:38:59intended to contain ingredients

01:39:01that help you take care of your gums.

01:39:03Speaking of toothpaste,

01:39:05check the cap the next time you open a new tube,

01:39:08you might have a little surprise.

01:39:10There is a kind of pointy cone inside the cap,

01:39:13which allows you to pierce the toothpaste seal

01:39:16without cutting yourself or damaging your gums.

01:39:18Not to mention that it is more hygienic

01:39:20since you will not be able to transfer germs

01:39:22or other bacteria into the product itself.

01:39:24As for the articles to be placed

01:39:26on the counter of the bathroom,

01:39:28toothbrushes are equipped with a very practical accessory

01:39:31hidden in the hairs.

01:39:33In addition to giving the toothbrush

01:39:35a cooler look,

01:39:37they also have a practical purpose.

01:39:39Most toothbrushes

01:39:41are equipped with a pattern of blue hairs

01:39:43interlaced in white hairs.

01:39:45This blue tint is intended to pale

01:39:47to indicate when you should replace your toothbrush.

01:39:50Dentists say that toothbrushes

01:39:52must be replaced every 3 to 4 months,

01:39:54but this gives a good reminder in case of forgetfulness.

01:39:57Do you still like to play with Legos?

01:39:59I'm not judging you,

01:40:01it's a great hobby for all ages.

01:40:03Note that there is a hole

01:40:05on the top of the Lego heads.

01:40:07This is a safety device

01:40:09designed by Lego people

01:40:11to avoid the risk of suffocation.

01:40:13The most dangerous problem

01:40:15if a person swallows one of these pieces

01:40:17is the obstruction of the respiratory tract.

01:40:19The presence of a hole

01:40:21inside the Lego head

01:40:23allows the air to flow freely

01:40:25through the piece

01:40:27until it can be safely removed.

01:40:29We are now used to all kinds of modern bulbs,

01:40:31some in tubular shape,

01:40:33others in diamond shape

01:40:35Historically,

01:40:37bulbs were round

01:40:39and this initial shape was useful in itself.

01:40:41It was mainly due to the fact

01:40:43that glass bulbs were blown by hand,

01:40:45which gave them this round shape at first.

01:40:47The practical reason

01:40:49was that the filament of the bulb

01:40:51had to be at the same distance

01:40:53from each surface of the glass sphere.

01:40:55The easiest way to achieve this

01:40:57was to make the glass in the shape of a globe.

01:41:05Don't grab the glass with your hand.

01:41:07Yep, that's it.

01:41:09The glass has a stem for a good reason.

01:41:11If you touch the glass with your hands,

01:41:13the temperature of the drink will be changed

01:41:15and it will warm up much faster.

01:41:17Since we are in the kitchen,

01:41:19let's look at your refrigerator.

01:41:21Most of them have an area reserved for eggs

01:41:23on the door shelves,

01:41:25but this may not be the best solution to keep them.

01:41:27The temperature in the door shelves

01:41:29tends to be a little higher

01:41:31than in the refrigerator itself.

01:41:33This is why it is important

01:41:35to keep delicate foods,

01:41:37such as eggs or dairy products,

01:41:39in the refrigerator.

01:41:41Don't forget this

01:41:43during your next visit to the supermarket.

01:41:45By the way,

01:41:47while we go through the contents

01:41:49of the refrigerator,

01:41:51did you know that waiting

01:41:53for food to cool down

01:41:55before refrigerating it

01:41:57can be bad for them?

01:41:59Keeping food at room temperature

01:42:01What did I just see in your fridge?

01:42:03Chocolate?

01:42:05Well, it's a big NO!

01:42:07Whatever the season,

01:42:09never forget that you should not keep chocolate

01:42:11in the refrigerator.

01:42:13Low temperatures inside

01:42:15can weaken the taste of cocoa.

01:42:17In addition,

01:42:19who wants to eat hard chocolate like stone?

01:42:21As for breakfast,

01:42:23the next time you boil an egg,

01:42:25try to put a teaspoon of baking soda

01:42:27in the water at the time of cooking.

01:42:29Another tip is to break the egg

01:42:31on one end and pass it under the tap.

01:42:33The water jet will allow

01:42:35the shell to peel off more quickly

01:42:37and with much less damage.

01:42:39Smoothies fan?

01:42:41Did you know that there is a proper way

01:42:43to fill your blender?

01:42:45Start with liquids,

01:42:47then add solids as you go.

01:42:49The movement created by the movement of the liquids

01:42:51will guarantee a small lunch

01:42:53or a homogeneous,

01:42:55unclogged and delicious snack.

01:42:57If you want a peanut butter sandwich,

01:42:59but this one is all divided,

01:43:01with oil on top,

01:43:03remember that there is a proper way

01:43:05to keep it.

01:43:07By placing the peanut butter pot

01:43:09upside down in your cupboard,

01:43:11you make sure that the oils

01:43:13are evenly distributed.

01:43:15You like a good steak,

01:43:17but you never get a perfect consistency?

01:43:19Well,

01:43:21if you like a good steak,

01:43:23but you never get a perfect consistency?

01:43:25You may start too early.

01:43:27You must let the meat rest

01:43:29after cooking for at least 10 minutes

01:43:31before starting to cut it.

01:43:33The use of a good knife

01:43:35will also give you better results.

01:43:37A well-sharpened knife

01:43:39will allow you not to lose the juice of the meat.

01:43:41It's pasta night!

01:43:43Have you ever wondered

01:43:45why there is a hole in the middle

01:43:47of the spaghetti spoon?

01:43:49It turns out that you can use this hole

01:43:51to check the amount of pasta to cook per person.

01:43:53It turns out that you can use this hole

01:43:55to check the amount of pasta to cook per person.

01:43:57When you use non-stick pans,

01:43:59never use metal utensils.

01:44:01Choose wooden or plastic utensils.

01:44:03Metal is too hard

01:44:05for the surface of your pans

01:44:07and can damage the non-stick surface.

01:44:09Are you the kind of person

01:44:11who keeps leftovers for dinner?

01:44:13Yes, well, me too, you know.

01:44:15A little tip to heat your dinner in the microwave.

01:44:17Try to spread the food

01:44:19on the edges of the plate.

01:44:21The microwave is designed to heat the food

01:44:23as evenly as possible,

01:44:25but not if the food is stacked.

01:44:27Have you ever tried to take

01:44:29a single tic-tac out of its little box?

01:44:31Just turn the box on the side.

01:44:33A small notch is provided for this effect

01:44:35on the upper plastic part.

01:44:37No need to shake the tic-tac box like a madman.

01:44:39No need to shake the tic-tac box like a madman.

01:44:41If you want to listen to music

01:44:43but you don't have a speaker in your hand,

01:44:45don't worry.

01:44:47By placing your phone in a cup or a bowl,

01:44:49you can clean it and your experience will be much better.

01:44:51Are you in a hurry

01:44:53and your phone has no battery left?

01:44:55There is a simple way to reduce the charging time.

01:44:57Just put the phone in airplane mode.

01:44:59You'll see,

01:45:01it will recharge 100% in no time.

01:45:03We all keep our phones

01:45:05in all kinds of places.

01:45:07Our pockets, our bags, under our pillows.

01:45:09Thus, a lot of dust or mucus

01:45:11can get stuck in the charging port.

01:45:13For safety reasons,

01:45:15you have to turn off the phone before cleaning it.

01:45:17You can use specially designed tools

01:45:19to clean the charging ports,

01:45:21the speakers or the microphone.

01:45:23Just go slowly.

01:45:25Nice desk you have there.

01:45:27Did you know that these little feet

01:45:29at the back of the keyboard are actually there

01:45:31to help you see the keys better?

01:45:33However, if you can type without having to look at the keyboard,

01:45:35don't use them to lift the keyboard.

01:45:37This position can damage your wrists

01:45:39if it is used for long periods.

01:45:41If you like to keep your things organized

01:45:43and you prefer to use post-its,

01:45:45make sure to simply remove them

01:45:47from the post-it cube

01:45:49from one side to the other

01:45:51to prevent them from rolling over.

01:45:53We all feel a little overwhelmed

01:45:55when it comes to storage,

01:45:57especially when it comes to home laundry.

01:45:59A simple way to make sure

01:46:01that you will never mix up the sheets

01:46:03is to store each set in the corresponding headrest.

01:46:05Not only will you have easy access

01:46:07to each window,

01:46:09but the shelves will be prettier to look at.

01:46:11When it comes to storing clothes,

01:46:13they are perhaps bigger and heavier

01:46:15than plastic belts,

01:46:17but they can also help push back the limits.

01:46:19Keep that in mind,

01:46:21especially when you store winter clothes.

01:46:23Have you ever wondered

01:46:25what this little extra opening

01:46:27in your racing shoes hides?

01:46:29The one that's right next to your ankles?

01:46:31Well, it turns out it's there for a good reason.

01:46:33The tighter the laces on your shoes are,

01:46:35the less chance you have of getting blisters.

01:46:37Always adjust your shoes correctly

01:46:39and use this extra loop in your shoes

01:46:41before you go racing.

01:46:43Your shirts also have a little secret.

01:46:45In the middle of the shirt,

01:46:47just between the shoulders,

01:46:49there is a small loop

01:46:51that you can use to hang your clothes

01:46:53when you don't have a belt on hand.

01:46:55Nothing could be better to waste

01:46:57good holidays than a poorly organized luggage.

01:46:59To make sure you never have to

01:47:01stuff your luggage with a lot of clothes,

01:47:03try to roll up your clothes

01:47:05and place them properly in your luggage.

01:47:07This way, you'll save a lot of space,

01:47:09you'll have easy access to everything

01:47:11you need,

01:47:13and your clothes will be less frizzy.

01:47:15I don't want to be indiscreet,

01:47:17but there are several things

01:47:19I'd like to show you in the bathroom.

01:47:21Wash your hands for at least 20 seconds

01:47:23to get rid of all the germs.

01:47:25To save effort,

01:47:27open and close the tap

01:47:29with your wrist if possible.

01:47:31And there you go,

01:47:33you'll have hands that are perfectly clean

01:47:35for a long time.

01:47:37Brush your hair from the bottom

01:47:39if you want to get rid of knots.

01:47:41Brushing your hair from the top

01:47:43will only damage them more.

01:47:45When you wash them,

01:47:47make sure to focus the shampoo

01:47:49on the scalp.

01:47:51However, make sure

01:47:53to never apply the shampoo

01:47:55directly on your head.

01:47:57Make it a little foamy with water

01:47:59between your hands

01:48:01before starting to massage it.

01:48:03You can avoid washing the tips of your hair

01:48:05if the amount of shampoo is sufficient

01:48:07to clean this part.

01:48:09Also take care of your scalp.

01:48:11If you leave it in a wet and hot shower,

01:48:13it may accumulate all kinds

01:48:15of unpleasant bacteria.

01:48:17Throw it in your dirty laundry

01:48:19once a week or let it soak

01:48:21in a diluted Javel solution.

01:48:23We're sure you're still hydrating

01:48:25after the shower,

01:48:27but there's also a proper way to do it.

01:48:29Don't put too much cream

01:48:31on your face

01:48:33and don't rub it.

01:48:35Your skin will thank you for that.

01:48:39You don't need to be a dentist

01:48:41to know how important

01:48:43dental floss is.

01:48:45Next time, try to make a knot

01:48:47with your floss.

01:48:49Thanks to the extra tension

01:48:51and grip,

01:48:53your teeth will be cleaner

01:48:55in no time.

01:48:57Have you ever wondered

01:48:59what these extra holes

01:49:01are for?

01:49:03It's useful when you want

01:49:05to make up for things

01:49:07like a bad stroke

01:49:09or even a damaged toe.

01:49:11You can also modify

01:49:13the look of your shoes

01:49:15as you wish.

01:49:17Many people use

01:49:19the cover of their books

01:49:21as a page marker.

01:49:23It's not a problem.

01:49:25Thanks to it,

01:49:27you won't have to crop your pages.

01:49:29If you spill fruit juice

01:49:31or drop food on your book,

01:49:33you can read it.

01:49:35The box has a little groove

01:49:37on top

01:49:39so you can distribute

01:49:41a single tic-tac at a time.

01:49:43Even if, let's be honest,

01:49:45no one does that.

01:49:47Most of us spill a lot at once

01:49:49and then put all the tic-tacs

01:49:51in excess.

01:49:53These little rubber tips

01:49:55are there for your safety.

01:49:57You can also adjust

01:49:59the minimum height

01:50:01of your tire.

01:50:03If the tips and edges

01:50:05are equal,

01:50:07it's time for you

01:50:09to go to a tire shop

01:50:11as soon as possible.

01:50:13But if the wear is still there

01:50:15compared to the edges,

01:50:17you can drive safely.

01:50:19What about this black

01:50:21grid on the microwave glass?

01:50:23It's called a Faraday cage.

01:50:25Your meal won't cook properly either.

01:50:27Indeed, this cage is not there

01:50:29to prevent you from seeing your meal

01:50:31while it's cooking,

01:50:33but so that the electromagnetic energy

01:50:35stays inside.

01:50:37And why not a screwdriver

01:50:39compatible with a wrench?

01:50:41Grab your screwdriver with the end

01:50:43of your wrench to increase

01:50:45its torsion force.

01:50:47That's why the head of your screwdriver

01:50:49is designed as it is.

01:50:51When you have weird angles,

01:50:53you probably already heard this myth.

01:50:55The blue side of the eraser

01:50:57can erase the pencil.

01:50:59It's wrong.

01:51:01Its purpose is also to erase the pencil.

01:51:03But in case you write something

01:51:05on a more robust paper,

01:51:07the blue side can also remove

01:51:09these traces that may remain

01:51:11after using the pink eraser.

01:51:13Have you ever wondered

01:51:15why oranges in supermarkets

01:51:17were most often

01:51:19in red-stripe bags?

01:51:21Don't throw this bag away.

01:51:23Tie it to have enough to cook

01:51:25your pans and clean your sink,

01:51:27your kitchen appliances,

01:51:29as well as your dishes.

01:51:31You can see that golf balls

01:51:33don't have a perfectly round shape.

01:51:35Their surface is covered

01:51:37by many small sockets,

01:51:39which golf balls didn't always have.

01:51:41At some point, experienced golfers

01:51:43began to notice that over time,

01:51:45old balls with imperfections,

01:51:47such as notches and bumps,

01:51:49would go too far.

01:51:51These asperities create turbulence

01:51:53in the air around the golf ball,

01:51:55which ends up reducing its drag.

01:51:57Manufacturers therefore began

01:51:59to produce balls with sockets

01:52:01so that they can go further and faster.

01:52:03You may have noticed

01:52:05that there were sometimes

01:52:07small ridges on the top of the toothpicks.

01:52:09It's more hygienic,

01:52:11because when you break it,

01:52:13you can press the toothpick

01:52:15on it and it won't touch anything else.

01:52:17Another safety device

01:52:19that you will find in your car

01:52:21is a strap on your rearview mirror.

01:52:23With it, you can change the position

01:52:25of the mirror so as not to be blind

01:52:27if there is a car behind you

01:52:29driving in the headlights.

01:52:31This little strap helps you

01:52:33to control the glow of the lights

01:52:35coming from the rear.

01:52:37This function appeared in the 1930s,

01:52:39but it was only in the early 1970s

01:52:41that it became a standard equipment

01:52:43for most cars and other trucks.

01:52:45There is a hole on your iPhone

01:52:47right next to the rear-facing camera.

01:52:49It's a microphone,

01:52:51and it's there so that your phone

01:52:53can record the sound

01:52:55when you rotate your camera.

01:52:57Some cables have a thick cylinder

01:52:59towards the end of the cord.

01:53:01It's called a ferrite core.

01:53:03It's a magnetic iron oxide

01:53:05that stops electromagnetic interferences

01:53:07at high frequencies.

01:53:09You see, for example,

01:53:11this annoying static noise

01:53:13when you're too close to a speaker.

01:53:15It interferes with your call.

01:53:17That's why cables with big cylinders

01:53:19are rather useful

01:53:21because they prevent this kind of thing.

01:53:23Do you know why

01:53:25almost all luggage bags

01:53:27and backpacks have two zippers?

01:53:29It's much more practical

01:53:31and easier to open this way.

01:53:33But that's not all.

01:53:35You can also lock these two zippers

01:53:37together so that the things

01:53:39inside your bags are safe.

01:53:41Just like shopping malls

01:53:43have these large spaces at the bottom of the door,

01:53:45it's mainly for better air circulation.

01:53:47This type of door also allows

01:53:49you to clean the toilets more easily

01:53:51or check if they are occupied

01:53:53when you wait.

01:53:55Apart from that,

01:53:57if you're stuck inside

01:53:59and the lock is broken,

01:54:01you still have a way out.

01:54:03You can just crawl out.

01:54:05You've already noticed

01:54:07these plastic tips on the cutters.

01:54:09They have a notch,

01:54:11so you can always

01:54:13renew them.

01:54:15You can separate these pieces

01:54:17with these plastic tips.

01:54:19Then you just have to move

01:54:21the sliding part to push

01:54:23this new blade forward.

01:54:25If you've ever checked a

01:54:27Lambda shopping cart,

01:54:29especially its foldable section,

01:54:31you've probably noticed

01:54:33these metal loops.

01:54:35They are designed to protect

01:54:37the metal loops.

01:54:39You can use them to hang

01:54:41bags containing soft items

01:54:43like bread that you don't want

01:54:45to accidentally crush

01:54:47with heavier products

01:54:49or things that are easier

01:54:51to break like eggs.

01:54:53Many coffee cups have

01:54:55curved notches on the bottom.

01:54:57When you wash your cups,

01:54:59place them against the drawer

01:55:01of your dishwasher.

01:55:03This way,

01:55:05you don't have to worry

01:55:07about spilling coffee.

01:55:09If you're a fan of McFlurry,

01:55:11you've probably noticed

01:55:13there was a square hole

01:55:15in the handle of their spoon.

01:55:17It's there so you can

01:55:19attach it to this special machine

01:55:21that mixes the ice cream

01:55:23with your favorite toppings.

01:55:25The machine has a bar

01:55:27that slides into this square-shaped

01:55:29spoon and gently stirs it.

01:55:31And you get this spoon

01:55:33on the side.

01:55:35Some people might think it's random,

01:55:37but this bar has several purposes.

01:55:39One of them is to inflate

01:55:41if there's an accumulation of gas.

01:55:43It happens when your milk

01:55:45has turned.

01:55:47So you don't even need to taste it

01:55:49to check.

01:55:51In addition, the bar is there

01:55:53so that the bottle doesn't explode

01:55:55if you drop it accidentally.

01:55:57It allows an expansion space

01:55:59that takes in the sudden pressure

01:56:01of your teeth.

01:56:03It's important to take care of your teeth,

01:56:05and it's easy to guess how to use it.

01:56:07But it's also great in the kitchen

01:56:09because it's a very precise cake cutter.

01:56:11Much more efficient

01:56:13than an ordinary knife.

01:56:17Most kitchen scissors

01:56:19have a keyhole right here in the center

01:56:21where the blades and handles meet.

01:56:23It's something you can use

01:56:25to trim difficult herbs

01:56:27like thyme or rosemary.

01:56:29Thanks to this opening,

01:56:31you don't need to remove

01:56:33the leaves by hand,

01:56:35but you can remove them

01:56:37in one move.

01:56:39A large part of the yogurt

01:56:41or flan skins

01:56:43come with an aluminum paper lid.

01:56:45In most cases,

01:56:47you can use this lid

01:56:49as a disposable spoon.

01:56:51Just take it off

01:56:53and after a few simple folds,

01:56:55you'll have a perfect spoon

01:56:57for a meal or dessert.

01:56:59What would you say

01:57:01about instant noodles instead?

01:57:03Your stomach is growling,

01:57:05but there's a problem.

01:57:07The polystyrene cup is broken

01:57:09and the noodles are outside.

01:57:11Wait, what's this space

01:57:13at the bottom of the cup?

01:57:15This space is meant

01:57:17to protect the noodles.

01:57:19It's not the company

01:57:21trying to save money

01:57:23or anything like that.

01:57:25The cup is never broken,

01:57:27while the one in the package

01:57:29comes out in bad shape.

01:57:31This technique is called

01:57:33an intermediate suspension.

01:57:35The noodles are tight

01:57:37to prevent them from

01:57:39crashing into the delivery truck.

01:57:41It's not just to make

01:57:43the noodles look beautiful

01:57:45and long.

01:57:47It's also to make

01:57:49these delicious noodles

01:57:51softer and more regular.

01:57:53The mouthwash was invented

01:57:55to wash your mouth.

01:57:57Well, no.

01:57:59The mouthwash was originally

01:58:01invented to clean the floor.

01:58:03It was sold to hospitals

01:58:05as an antiseptic for years,

01:58:07but it never really

01:58:09took off.

01:58:11A marketing genius

01:58:13renamed it mouthwash.

01:58:15The rest is a fresh story.

01:58:17So after cleaning your teeth,

01:58:19don't forget that sometimes

01:58:21mouthwash can be dangerous.

01:58:23It's difficult to imagine

01:58:25a world without the Internet

01:58:27these days.

01:58:29No streaming, no online games,

01:58:31no pictures of cute kittens.

01:58:33Yes, I know that's not

01:58:35why it was invented,

01:58:37but who cares, right?

01:58:39The Internet prototype

01:58:41was called ARPANET,

01:58:43acronym for Advanced Research

01:58:45Projects Agency Network.

01:58:47This machine was very sensitive

01:58:49and, to make matters worse,

01:58:51an intelligent scientist

01:58:53stuck a piece of paper on it

01:58:55with these striking words.

01:58:57This machine is a server.

01:58:59Don't turn it off.

01:59:01It was written in red ink,

01:59:03nicely drawn.

01:59:05The fact that your teacher

01:59:07scribbles in the margins

01:59:09of your notebook is not really new.

01:59:11Except that the margins

01:59:13were not designed for that.

01:59:15It's a protection against rats.

01:59:17Well, it ended up

01:59:19in the stomach of a hungry rat.

01:59:21A few well-placed margins

01:59:23prevented your best answers

01:59:25from being eaten.

01:59:27Hey, I can't finish this pizza.

01:59:29It's time to cover up the leftovers.

01:59:31Luckily, I have a lot of plastic film.

01:59:33A little pull,

01:59:35and the roll comes off.

01:59:37Cool!

01:59:39If you look at the packaging,

01:59:41this long and thin box,

01:59:43there's a little peculiarity

01:59:45on each end.

01:59:47Push them inwards,

01:59:49and the roll won't move.

01:59:51It's strange that I've never seen them before.

01:59:53It's lunchtime.

01:59:55I feel like a Californian today.

01:59:57Algae, rice, cucumbers,

01:59:59avocado, and crab meat.

02:00:01Or maybe it's...

02:00:03Actually, it's imitation crab meat.

02:00:05It's basically a cheap white fish

02:00:07mixed with sugar.

02:00:09The fish mixture is then heated

02:00:11and shaped. It's delicious.

02:00:13Maybe that's why

02:00:15it's called the hot dog of the sea.

02:00:17No, I just made that up.

02:00:21Your microwave has a secret

02:00:23that we've all seen,

02:00:25but we've never paid attention to.

02:00:27This black net you see on the door

02:00:29is a Faraday cage.

02:00:31It prevents electromagnetic energy,

02:00:33or microwaves, from escaping

02:00:35and cooking you at the same time.

02:00:37That's how they heat up

02:00:39food so quickly.

02:00:41Each microwave must have one,

02:00:43and they're all of different qualities.

02:00:45This Faraday cage can even

02:00:47stop the signals on your phone,

02:00:49which is certainly useful.

02:00:51And you don't need your popcorn

02:00:53to stop swelling to make a call,

02:00:55do you? For that, the airplane mode

02:00:57is much easier to manage.

02:00:59Have you ever passed a IQ test

02:01:01and realized you had

02:01:03Einstein's IQ? No?

02:01:05Me neither. The immediate IQ

02:01:07is not 100, and there's

02:01:09no proof that Einstein

02:01:11ever passed the test.

02:01:13At first, most people thought

02:01:15the tests were too vague

02:01:17to be used for anything.

02:01:19This test was designed for children

02:01:21who needed help with their studies.

02:01:23Later, they realized they could

02:01:25be adapted to measure intelligence.

02:01:27But originally, they didn't aim for that.

02:01:29Hey, have you ever blown up

02:01:31bubble wrap? No?

02:01:33You're missing something.

02:01:35And of course, you guessed it,

02:01:37bubble wrap has never been designed

02:01:39to be blown up or used

02:01:41as we do today.

02:01:43It was invented as new textured bubble wrap.

02:01:45It's by sealing two shower curtains

02:01:47together that they created

02:01:49the first bubbles.

02:01:51The idea has never really

02:01:53found its audience.

02:01:55After failing as bubble wrap,

02:01:57it discovered the true meaning

02:01:59of its life.

02:02:01This bubble wrap could protect

02:02:03fragile objects.

02:02:05Do you think it's cool or not?

02:02:07Leave a comment below.

02:02:09If you owned one of the

02:02:11biggest companies in the world

02:02:13selling one of the most famous products on the planet,

02:02:15how would you keep the secret of your company?

02:02:17A secret?

02:02:19The Coca-Cola formula is not even

02:02:21patented. The first recipe was,

02:02:23but when they made changes,

02:02:25no patent has ever been filed.

02:02:27The secret formula

02:02:29is only known to a few people

02:02:31in the company.

02:02:33Even the rival of Coca-Cola

02:02:35doesn't want this recipe.

02:02:37In 2006, an unhappy employee

02:02:39tried to sell the secret,

02:02:41but he didn't find a buyer.

02:02:43Hey, look at your brand new mattress.

02:02:45Do you see the label?

02:02:47Don't take it off under legal proceedings.

02:02:49This thing looks pretty serious,

02:02:51but good news, the labels

02:02:53are not for you. They are intended

02:02:55for mattress sellers.

02:02:57100 years ago, mattress manufacturers

02:02:59created their filling with

02:03:01anything. Animal fur,

02:03:03old hospital beds, or even

02:03:05clothes. Then,

02:03:07strict laws prevented the use

02:03:09of these weird materials.

02:03:11Hospital mattresses were thus filled

02:03:13with germs.

02:03:15When it rains,

02:03:17the water-filled modeling paste is great

02:03:19to take care of at home.

02:03:21Mix flour, water, salt,

02:03:23food coloring, and voila!

02:03:25Any creative person

02:03:27can have fun with it

02:03:29for hours. Good price,

02:03:31clean, non-toxic,

02:03:33perfect modeling paste.

02:03:35But it was never designed for that.

02:03:37This product was originally

02:03:39intended to clean walls in the 1930s.

02:03:41It's because people

02:03:43started going crazy with wallpaper

02:03:45on which you couldn't use water

02:03:47or soap.

02:03:49In the end, Pledo found new functions

02:03:51and did really well.

02:03:53Well, have you ever finished

02:03:55a mattress and noticed a hole

02:03:57in the little stick?

02:03:59This hole is not just for decoration.

02:04:01And no, it's not designed to

02:04:03turn into a musical instrument.

02:04:05It's there to prevent this delicious

02:04:07sweet treat from falling.

02:04:09When the candy is still hot,

02:04:11it's poured into a mold.

02:04:13The candy flows into the hole,

02:04:15and when it hardens,

02:04:17it creates an anchor.

02:04:19You don't like lollipops?

02:04:21Why not some good old

02:04:23American gummy bears?

02:04:25German.

02:04:27A German company started

02:04:29making them in 1922.

02:04:31The original name was

02:04:33Gummy something.

02:04:35They were inspired by real bears

02:04:37dancing in shows.

02:04:39These treats ended up

02:04:41going around the world.

02:04:43Have you ever wondered

02:04:45what these little bumps

02:04:47on the F and J keys

02:04:49on your keyboard were for?

02:04:51These little grooves are

02:04:53for keeping your fingers on

02:04:55the F and J keys.

02:04:57This will make it easier

02:04:59to reach all the keys,

02:05:01especially if you don't look

02:05:03at the keyboard.

02:05:05Today, everyone loves

02:05:07Slinky.

02:05:09If you've ever seen one

02:05:11going down the stairs

02:05:13with a groovy music in the background,

02:05:15bravo, you're a YouTube fan.

02:05:17It was a huge success

02:05:19as soon as it came out.

02:05:21It's a spring.

02:05:23It was originally designed

02:05:25to stabilize the ship's

02:05:27sensitive nautical devices.

02:05:29So it's not a fun feature at all.

02:05:31And yet, one day,

02:05:33one of them fell off a table

02:05:35and danced right into our hearts.

02:05:37After many experiments,

02:05:39the improved Slinky was born.

02:05:41Let's give this team of scientists

02:05:43a medal.

02:05:45The little pocket of your jean

02:05:47wasn't designed to hold

02:05:49your pocket watch.

02:05:51You don't have a pocket watch?

02:05:53How is that possible?

02:05:55It was a hit in the 1890s.

02:05:57But that's not all

02:05:59that makes your old jean interesting.

02:06:01Look around your pockets.

02:06:03You'll see rivets that protrude.

02:06:05No, it's not a vestige

02:06:07of the fashion of the past.

02:06:09These rivets play a very important role.

02:06:11They protect the sensitive areas

02:06:13of the most worn jeans.

02:06:15At the time, most people

02:06:17couldn't do manual work,

02:06:19so they had to be resistant.

02:06:21If today these men saw you

02:06:23paying $100 for a torn jean,

02:06:25they'd probably faint in shock.
