00:00 Have you wondered why aren't keyboards organized in alphabetical order?

00:04 Well, modern laptop keyboards we all know go back to typewriters, and those, at first,

00:10 had piano-like keys and they were arranged alphabetically.

00:14 But it wasn't convenient.

00:15 Most commonly used letters were too close together, which resulted in frequent mechanical

00:19 jams, so typing was pretty annoying.

00:22 So Mr. Christopher Latham-Scholes, one of the inventors of the first typewriter, came

00:27 up with a QWERTY keyboard layout instead.

00:30 The idea behind that layout was to spread the most commonly used combination of letters

00:34 like ST or TH.

00:36 This way it was preventing mechanical problems.

00:39 This realignment helps the alternation between both hands, which increases the speed of typing.

00:45 Now why do we even need two shift keys if both do the same thing?

00:49 Well, it's just to make it more convenient to use with a single key on the keyboard.

00:54 When the key you need to use is located on the right side of the keyboard, you use right

00:58 shift, and when the key is on the left side, you use the left shift.

01:02 The same applies to two ALT and two CTRL keys.

01:06 Now even though they serve the same purpose, they still have different scan codes, and

01:11 you can assign each of them with different functions manually if you like.

01:15 For example, in an international keyboard setting, the right ALT allows typing a German

01:20 letter ESET while the left ALT won't do it.

01:24 These little feet keyboards are actually standard.

01:26 The height of the keyboard should be adjustable, allowing an angle between 0 and 15 degrees.

01:32 The recommended angle is 5 to 12 degrees, by the way.

01:36 The reason to fold the feet out is for you to see the keys better, in case you don't

01:40 touch type.

01:41 A little problem that comes with that is that, in this case, your wrists are bent, and it

01:46 can be tiring to keep them in this position and type.

01:49 So the feet are there to give you a choice.

01:52 The symbol here isn't some brand-new Internet invention.

01:55 No one knows exactly where it originated, but researchers date it back to Middle Ages

02:00 at least.

02:01 The first documentation found with that symbol is from the year 1536.

02:07 They say that "at" is short for the Latin word "ad," which means "at, to, or towards."

02:13 At first, they wrote it as "ad," but the upstroke of the "d" was curved left to

02:18 the "a."

02:19 With time, to make it shorter, the "d" was just replaced with the circle around the

02:23 "a."

02:24 It was also commonly used back in the older days to mark prices.

02:27 Then, for a while, the symbol disappeared.

02:30 It wasn't even in the first typewriters' keyboards.

02:33 But with the development of computers, people needed a symbol to connect several machines.

02:38 For example, they needed to send something to a particular user at a particular computer,

02:43 and the name of the user and the name of the computer had to be divided by something.

02:48 So they came back to the "at" symbol.

02:50 Meanwhile, the two sides of a cotton pad are different because each of them has a particular

02:55 purpose.

02:56 A cotton pad has several layers to ensure that it's soft, strong, and can absorb liquids.

03:01 The edges stitch to hold it all together.

03:04 The smooth side of the pad is for applying, and the side with the pattern is best for

03:08 cleansing and makeup removal.

03:10 Also, any pack of cotton pads has those strings on the sides.

03:14 They're there so you can hang the package somewhere.

03:17 Then you can open the package on the bottom, where the perforated line is, and take them

03:21 out from the bottom one by one.

03:24 Speaking of eggs, I think I will.

03:27 All eggs have numbers stamped on them, and they say something about the egg.

03:31 The first digit can be 0, 1, 2, or 3, and it tells you about how the egg was produced.

03:37 0 means it's organic, 1 says it's a free-range egg, 2 says that it's from the indoors, and

03:43 3 means it comes from furnished cages.

03:46 Sounds posh, doesn't it?

03:48 Then there are letters, which are country codes that tell you in what country the egg

03:52 was produced.

03:53 The other 4 of 5 digits are the exact code of the egg producer.

03:57 Also, there's a 3-digit number on the side of an egg carton, and that number indicates

04:02 the day of the year when the eggs were produced.

04:04 So 001 stands for January 1st, 120 stands for April 30th, and 365 is December what?

04:13 31st.

04:14 You were paying attention!

04:16 All eggs are typically either white or brown.

04:19 The color depends on the breed of the hen.

04:22 Typically white chickens lay white-shelled eggs, and dark chickens lay brown-shelled

04:26 eggs.

04:27 But even chickens of the same breed can lay eggs of different colors, depending on the

04:31 genetics of the particular hen.

04:33 Also, some chicken breeds lay bluish eggs.

04:36 And no, there's no nutritional difference between white and brown eggs.

04:40 Speaking of stuff to use in the morning, coffee stirring sticks have holes in them.

04:45 Plastic usually bends when put in hot drinks.

04:47 With the holes, the stick becomes sturdier and can withstand the heat.

04:51 The bonus is that there's less plastic required to produce them this way.

04:56 Have you noticed that a pair of wooden chopsticks are always connected?

04:59 Good for you!

05:00 It's a new pair!

05:02 This way, you can always find out if someone had used them before you.

05:07 Microwave ovens cook and heat up your food by using microwave radiation and making it

05:11 pass through your food.

05:13 This radiation can heat up your body just like it heats up the food.

05:16 That's why this radiation is dangerous for people, because it'll cause burns if one

05:21 is exposed to it.

05:22 That's why we now call my dad Pop.

05:26 For this reason, microwave ovens are designed in a way to prevent microwaves from escaping.

05:31 The door that is made of plastic and glass isn't enough to keep radiation inside.

05:36 So say thanks to this great pattern microwave ovens have on their doors.

05:40 It's made of metal and acts as a cage, not allowing the waves to pass.

05:45 So that pattern is always there to protect you.

05:50 With selfies taking over the social media world, phone companies had to adapt to the

05:54 way people hold their phones and use their cameras.

05:57 Apparently, most users tilt their heads slightly to the right when taking selfies.

06:02 With the camera located in the left corner, it makes it easier to make sure the camera

06:06 will be in line with the usual tilt of selfie-takers.

06:08 Ooh, genius!

06:11 This allows for a more natural look, making the image look better to leave you feeling

06:16 great.

06:17 Cameras on the back of most phones are on the left side as well.

06:20 Sorry, left-handers, this was designed for the more common right-hander.

06:25 Mount Everest might be getting all the attention, but Mauna Kea in Hawaii is technically the

06:31 tallest mountain in the world.

06:33 Measuring over 33,000 feet from base to summit, the only thing holding Mauna Kea back from

06:38 the title is that it's mostly underwater.

06:42 Australia is wider than the Moon.

06:45 The Moon has a diameter of over 2,100 miles, while Australia's diameter from coast to

06:50 coast is almost 2,500 miles.

06:53 While it may be wider, the Moon wins with the land area – over 15 million square miles!

06:59 Phew, that's huge!

07:01 And all that cheese!

07:03 Antedilophobia is the fear that, at any point, somewhere in the world, a duck or goose may

07:09 be watching you.

07:12 The person isn't necessarily afraid that the duck or goose will get too close to them

07:16 or even touch them.

07:17 They just don't like the feeling of being watched.

07:20 It was first described in a comic strip to show how anyone can be afraid of anything.

07:26 Anything can be a phobia.

07:27 A duck just watching my every move would certainly give me the heebie-jeebies.

07:32 I might just quack up!

07:34 Crows are pretty good at recognizing people's faces and have even been found to remember

07:39 people for a long time.

07:41 This could be a good thing or a bad thing, depending on how nice you are to them.

07:45 You don't want to come across a crow that's holding a grudge against you.

07:49 You probably can't tell which crow is which very easily, so it might be better to play

07:53 it safe and just give them all a little wave.

07:59 In the city of Yoro, in Central America, they have an annual event known as the "Rain of

08:04 Fish."

08:05 Not that the locals get a choice for it anyways.

08:08 Every year in May or June, a torrential rainstorm rolls through town, leaving a mass of fish

08:14 flopping around in the streets.

08:16 The phenomenon is believed to be caused by water spouts or water tornadoes, which drop

08:21 the fish far from home.

08:23 Seafood delivery for free?

08:24 Yes, please!

08:26 A photon, the most basic part of light, takes thousands, maybe millions of years to travel

08:31 from the Sun's core to its surface.

08:33 But it only takes 8 minutes and 20 seconds, on average, to get to your eye once it's

08:38 at the surface.

08:39 That means that the sunlight we see is very ancient, older than the human race itself.

08:45 There are only four words in the English language which end in -dos.

08:49 Tremendous, horrendous, stupendous, and hazardous.

08:54 Things like the teacher's comment on my report card.

08:57 A single strand of spaghetti onto your fork has a name.

09:01 It's called a "spaghetto."

09:04 In the Italian language, an "i" at the end of the word means that it's plural, while

09:08 an "o" is singular.

09:10 This goes for all types, like gnocco instead of gnocchi, fettuccino instead of fettuccini,

09:16 and raviolo for a single parcel of goodness.

09:21 Accidentally eating one of those fruit stickers on apples, peaches, and pears shouldn't worry

09:25 you at all.

09:27 They can be eaten, but they aren't exactly edible.

09:30 It'll just leave your body as everything else does.

09:34 The glue used for them is regulated by the FDA, but it's still recommended that you

09:38 wash the fruit and remove the sticker before chomping down on it.

09:43 Dolphins not only have names for each other, but they'll call out for their friends specifically.

09:50 Bet you wonder what names dolphins have for us when we get in the water.

09:54 "Hey look, Frank, those hairless monkeys are back in the water again!"

09:59 German chocolate cake is one of the most delicious cakes out there.

10:03 It's my all-time favorite, but its name has nothing to do with the country at all.

10:09 Named after an American baker called Samuel German, who made the tasty treat in 1852.

10:16 The Eiffel Tower can be 6 inches taller during the summer because of thermal expansion.

10:22 When the iron heats up during really hot days, the iron particles expand, taking up even

10:27 more space.

10:29 Two planets in our solar system rotate the opposite way as the others.

10:33 Venus and Uranus have this backward rotation.

10:37 Venus also has the longest day of any planet in our solar system, completing a rotation

10:42 every 243 Earth days.

10:46 A baby puffin has the adorable name of "puffling."

10:50 To feed its chick, the puffin parent will carry about 10 fish in its beak at a time.

10:57 While you sleep, you can't smell anything.

11:01 Even really, really bad or potent smells.

11:05 Our taste and smell senses are cut down by 50-20% during flights.

11:10 This is why airplane food always tastes like cardboard or too salty.

11:15 Sounds like a pretty convenient excuse from the airlines to me.

11:20 Look at any watch advertisements, and the time on display should be 10-10.

11:25 This is because of the positive effect it has.

11:27 It looks like a smile, and usually, the brand name of the watch is directly below the 12.

11:34 Stewardesses is the longest word that is typed with only the left side of the keyboard.

11:39 The word itself isn't used much anymore.

11:41 Most people say "flight attendant" instead.

11:44 Those dum-dums who call out "hey, you!" are normally invited to exit the aircraft mid-flight.

11:50 The Moon has volcanoes, and scientists believe they might have been active around 100 million

11:57 years ago, when dinosaurs still ruled our planet.

12:00 The view must have been magnificent.

12:04 Cockroaches are tough.

12:05 They can survive harsh conditions and have been around since dinosaurs ruled our planet.

12:11 But the termite queen beats all that with a lifespan of 50 years.

12:15 That's the longest any insect can live.

12:18 Regular termites live only 1-2 years.

12:23 It's estimated that a total of 108 billion people lived on Earth throughout history.

12:29 The entire population of Earth could fit inside Los Angeles.

12:33 With the world's population being 7.5 billion, this seems crazy.

12:38 But if everyone stood shoulder to shoulder, we could all fit inside 500 square miles.

12:46 The tuatara is a reptile that has a third eye on top of its head.

12:50 The eye has a retina, nerve connections, and a lens, but isn't used for seeing as during

12:56 growth it quickly becomes covered by scales.

13:00 Scientists are still trying to find the eye's mysterious function.

13:05 Camels have three sets of eyelids and two rows of eyelashes to protect them from the

13:10 blowing sands of the desert.

13:13 The pandas in your local zoo may look at home, but unless you're in China, they're just on

13:19 vacation.

13:20 That's because technically all pandas are on loan from China and are the property of

13:25 that country.

13:27 A full current NASA spacesuit cost between $15 and $22 million in 1974, but NASA hasn't

13:36 actually built any new suits since '74, leading to them only having four working suits left.

13:43 If they are to create another suit, in today's money, that would translate to a cost of $150

13:49 million.

13:50 A tiny percentage of static that you see on an old TV screen is residual radiation left

13:57 over from the Big Bang.

14:00 If you're heading to London to see the famous London Bridge, think again, as the original

14:05 bridge is now in Arizona.

14:08 By the 1960s, London Bridge was falling down, so the city decided to sell it to an American

14:15 oil tycoon, Robert P. McCullough.

14:18 It was shipped over to the US and can now be found in Lake Havasu City.

14:24 Speaking of England, the crown jewels contain two of the largest cut diamonds of all time.

14:30 The Cullinan Diamond is the largest diamond ever found and is part of the Sovereign Scepter

14:35 with Cross.

14:37 The second gem is the aptly named Cullinan II, which is mounted in the impressive Imperial

14:43 State Crown.

14:45 The real giants among diamonds, though, could be raining down on Jupiter and Saturn as you

14:50 watch this video.

14:52 That's because lightning storms turn methane into carbon, which gradually hardens as it

14:57 falls and turns into diamonds.

15:01 Next time you're struggling to concentrate when studying, try reaching for a stick of

15:05 gum.

15:06 A study found that participants who chewed gum while taking a memory test could stay

15:11 focused longer than those who didn't.

15:15 Common sense would suggest that trees have been around before most animals as they produce

15:19 oxygen for us to breathe.

15:21 If you were to tell this to a shark, it would laugh as the sea creatures were actually around

15:26 long before trees.

15:29 Sharks date back around 400 million years, with trees coming in at about 50 million years

15:34 later.

15:36 The Comic Sans font has divided people across the world for decades and has developed a

15:42 reputation for being informal or unprofessional.

15:46 This makes perfect sense given its creation, as designer Vincent Canare looked to his favorite

15:51 comic books like Watchmen for inspiration.

15:55 If you're looking for a bodyguard from the animal kingdom, look no further.

15:59 The silverback gorilla can lift up to 10 times its own body weight, which translates to a

16:04 total of around 1,800 pounds.

16:07 This makes them one of the strongest living mammals on Earth.

16:12 Humans are the only animals with chins, while other animals like the chimpanzee share similarities

16:18 with humans, like walking on two legs or having a jaw.

16:21 None actually have that little bit of bone in the middle of the lower jaw.

16:27 Movie trailers were originally shown after the movie, which is why they're called trailers.

16:33 The current American flag was designed by a high school student.

16:38 Bob Heft designed the flag for his history class in 1958 and was only given a B- for

16:44 his efforts.

16:45 Later, his design was chosen out of more than 1,500 others to become the new flag.

16:51 His grade was unsurprisingly changed to an A after this.

16:55 Unlike humans, cats don't have the same amount of toes on their front and back paws.

17:01 They usually have five toes on their front paws, but only four on their back ones.

17:06 If you've got a feline companion, go and take a look!

17:10 Ever wondered what that tiny pocket in your jeans is for?

17:13 It's a watch pocket, and was originally intended as a place to store pocket watches.

17:19 It dates back to 1879, to the first pair of Levi's jeans.

17:24 Your brain uses different hemispheres to store different memories.

17:29 Things you hear or read are stored in the left hemisphere, and pictures or events you've

17:34 seen in the right one.

17:37 Hidden beneath the ice and frozen earth in Antarctica and Siberia, there are two giant

17:43 viruses.

17:44 They are ten times larger than those we know, and can survive for tens of thousands of years.

17:51 There's a real-life Jurassic Park in Monaco.

17:54 The chem-chem beds are an extremely rich source of dinosaur fossils, with dozens of species

18:00 uncovered in the last few decades.

18:04 Around 34 million years ago, ancient primates crossed the Atlantic from Africa to South

18:10 America.

18:11 And nobody knows how!

18:12 Well, I hate to break this to you, but money isn't actually made of paper.

18:18 Which also proves that money doesn't actually grow on trees.

18:22 Most banknotes are 25% linen and 75% cotton, which is why they have such a distinct look

18:28 and feel.

18:29 Back in the 19th century, money was made of parchment paper.

18:32 That's why people could very easily counterfeit it, unlike now.

18:36 The Eiffel Tower is almost 6 inches taller during the summer.

18:40 When you heat up some substance, its particles start to move more actively and take up a

18:44 bigger volume.

18:46 That's something they call "thermal expansion."

18:48 When the temperature lowers, the substance contracts again.

18:52 Such an effect is more prominent in gases, but you can also track it in liquids and solids,

18:57 including iron.

18:59 Because of this, people build large structures like bridges using expansion joints.

19:04 They allow a structure some leeway to expand and contract.

19:08 And such changes don't cause any damage.

19:10 Wow, I have some pants like that!

19:12 Now honey can last for thousands of years without going bad.

19:17 Bees land on flowers to collect sugary nectar.

19:20 Then they transport it back to their hive and transfer it to other worker bees.

19:24 These bees reduce the water content of the nectar by repeatedly drinking and regurgitating

19:29 the liquid.

19:30 Mmm, bee barf.

19:32 Special enzymes in their stomachs break down the glucose in the nectar, and it becomes

19:36 more acidic.

19:38 Bees deposit this nectar in the honeycomb and start fanning it with their wings so that

19:42 the water evaporates more quickly.

19:45 The honey is now highly acidic and low in water content, which keeps it safe from spoiling.

19:50 The bacteria that can cause the rest of the food to go off can't survive in such conditions.

19:56 A long time ago, people didn't elevate their mattresses off the floor.

20:00 This practice started in ancient Egypt and continued in many other cultures.

20:05 People realized it was cold on the floor, and they could warm their beds easier if they

20:09 were off the ground.

20:11 Houses used to be more drafty.

20:13 Cold air came in from under the doors.

20:15 There was no central heating, so people had to find other ways to stay warm.

20:20 Warm air tends to rise, and if you're positioned higher, you won't be as cold as on the floor.

20:25 Also this way, people could keep their beds clean more easily.

20:29 In simple homes, floors used to be way dirtier than today, and all that dirt usually migrated

20:34 into beds.

20:36 Continuing now to talk dirty, do you think people are naturally clean and tidy?

20:41 After all, our ancestors, who lived thousands of years ago, already used latrines and were

20:46 tidying their hair with combs.

20:48 And they kept their homes and themselves clean.

20:51 Our natural need for hygiene and cleanliness is driven by our sense of disgust.

20:56 That's the very mechanism that helps our body stay safe and protects them from different

21:00 infections.

21:01 That's why we're more sensitive to certain smells and things.

21:05 But we still have some pretty sloppy habits.

21:08 For example, eating snacks over a keyboard.

21:11 I certainly never do that.

21:13 But there are animals that are even neater than us humans.

21:16 For example, rattlesnakes like to keep their surroundings tidy.

21:20 Some of them even use their muscular necks and triangular heads to sweep aside messy grass

21:25 when they hunt.

21:27 Many animals like to clear their path when going after their future meal.

21:30 Reptiles too.

21:32 Less vegetation increases their chances of catching food.

21:36 Young birds also prefer to keep it neat and get rid of uneaten food, eggshells, and other

21:41 trash in their nests.

21:43 This way, they also make their homes less visible to their enemies.

21:46 Meanwhile, out in space, shadows are darker on the Moon than on our planet.

21:52 That's because the atmosphere on Earth scatters more sunlight.

21:55 But if you could visit the Moon, you'd observe shadows so dark you wouldn't be able to see

22:00 where you were going.

22:01 Also, you'd notice fresh footprints on the lunar surface.

22:05 People haven't set foot there in a few decades, but the footprints look as if they were left

22:09 just yesterday.

22:11 Since there's no water or wind on the Moon, nothing can erase these footprints.

22:16 So they stay there in their original form for millions of years.

22:20 So be careful where you step, huh?

22:23 Earth's core contains enough gold to coat the entire planet.

22:27 And if you decided to do this, the level of this precious metal would be knee-high.

22:32 For thousands of years, people have been mining gold and platinum, together with a bunch of

22:36 other precious metals, from underneath our planet's surface.

22:40 That's why we have depleted some of the minerals in certain areas.

22:43 But Earth still has a huge number of such deposits, especially if you get closer to

22:48 its core.

22:50 That's because of countless meteorites that collided with our planet during the period

22:54 of its formation.

22:55 Those meteorites contained different minerals, including gold.

22:59 Back then, Earth was still in its molten state, which is why most of the gold, a heavy element,

23:04 sank deep into its core.

23:06 And the silicate mantle positioned over the core trapped really huge amounts of gold and

23:11 some other minerals.

23:12 Unfortunately, most of them are kind of out of reach now, since we talk about 1,800 miles

23:18 below the surface and temperatures of thousands of degrees.

23:21 Too hot, in other words.

23:23 Sure, if you were about to go into space, one of the first things you'd think of would

23:28 be your space suit.

23:30 But do you know that it's possible to survive in space even if you aren't wearing any protection?

23:35 Well, don't get your hopes up yet.

23:37 It lasts for no more than 15 seconds.

23:40 That's how long it would take you to lose consciousness, because oxygen will stop coming

23:44 to your brain.

23:45 In 1965, one technician accidentally depressurized his suit inside a vacuum chamber.

23:51 He lost consciousness after 12 to 15 seconds.

23:55 27 seconds later, his suit luckily got repressurized.

23:59 The man later said that he remembered the moisture on his tongue started to boil.

24:04 He also lost his sense of taste, and it didn't come back until 4 days after the accident.

24:10 Now you can't hold your breath in space either, so that won't save you.

24:14 Your lungs will rupture at one point because the air inside will expand.

24:18 The oxygen in other parts of your body will start to expand too, which means you will

24:22 balloon up to twice your regular size, almost like Dudley Dursley's Aunt Marge from Harry

24:28 Potter.

24:29 Scientists have found that cell phones carry 10 times more bacteria than most toilet seats.

24:34 So yeah, you might want to sanitize your phone after watching this video.

24:39 Do you use FaceTime or Skype to talk to each other worldwide?

24:43 It could be for a chat, a meeting, or something else.

24:46 The webcam technology was born with a very reasonable goal though.

24:50 In 1993, researchers at the Computer Science Department at the University of Cambridge

24:55 set up a system to see if the coffee pot was empty or not.

25:00 Yes, you heard it right.

25:02 Researchers needed coffee to fuel their brains, as many of us do.

25:06 They get up from their chairs, go to the coffee pot, and find it empty.

25:10 Instead of making sure that someone makes a fresh coffee, they wired up a system.

25:15 The system would stream the images of the room where the coffee pot was kept.

25:19 At that time, it was three pictures taken per minute.

25:22 It's more than enough to see if the pot has coffee in it or not.

25:26 Thanks to the researchers for not getting up from their chairs.

25:29 And for another tiny thing, coming up with this brilliant idea!

25:34 Do you buy white eggs or brown eggs?

25:37 What's the difference besides the color?

25:39 Since brown eggs tend to cost you more, you might think that something in them makes the

25:44 prices a bit higher.

25:45 Nope!

25:46 The color of the egg shell doesn't affect its nutrition or quality.

25:51 Both eggs are healthy.

25:53 Brown eggs cost more because the hens that lay them need more feed.

25:57 It's more pricey to raise them than the white egg hens.

26:00 The cost is reflected onto the consumer.

26:03 There is a hole at the handle of some kitchen pots and pans.

26:07 We mostly use this hole to place the kitchen utensil vertically on a cabinet door.

26:12 They have a secondary use.

26:14 Imagine you're cooking multiple dishes to make a feast for the family.

26:18 The kitchen counter is full of stuff.

26:21 You have a hard time finding a place for the gravy sauce spoon.

26:25 You can place the spoon in the hole on the edge of the sauce pan handle.

26:28 It will stay there safely until you decide to stir the sauce again.

26:33 Not every spoon fits into the hole.

26:36 It might easily slide to the floor.

26:38 Better to have a test run where the spoon is clean.

26:42 Imagine you have a takeaway of noodles with an extra topping on your way home.

26:46 You recently moved and all the plates are in the boxes.

26:50 You struggle with this noodle box.

26:52 The toppings are stuck at the bottom.

26:55 The sauce didn't mix evenly either.

26:57 We've missed out on an easier way to eat from the takeout boxes.

27:01 They can be flat and serve as plates.

27:03 You take the edges of the paper out and open it up.

27:06 There you go.

27:07 Now you have a plate.

27:08 The best part is you don't have to clean it up afterwards.

27:13 Did you know that a tomato is not a veggie but a fruit?

27:16 So is an avocado.

27:19 Watermelon is actually a berry.

27:21 There's more to that.

27:23 Peanuts are not in the nuts family.

27:25 They're different from almonds and cashews.

27:29 Peanuts grow pods under the soil.

27:31 They're harvested like potatoes.

27:33 Their upper parts are like bushes.

27:36 These tasty ciders are not classified as nuts since they grow under the ground, not on a

27:41 tree.

27:42 They get pulled up from the soil like carrots.

27:45 Next time you eat peanuts in a friend circle, you can mention this new fact you heard.

27:50 Or it can be an icebreaker when you see someone eating peanuts.

27:54 Classifying food as fruit or a vegetable is a tricky business.

27:59 Do you know who invented t-shirts?

28:02 In 1904, the Cooper Underwear Company prepared an ad and introduced its new product with

28:08 before and after photos.

28:10 It was referred to as an undershirt.

28:13 The slogan was "No safety pins, no buttons, no needle, no thread."

28:18 As the name revealed, they were worn under the clothes.

28:22 One day it was announced that sailors should wear undershirts with no buttons under their

28:26 uniforms.

28:28 T-shirt love spread like pollen at a park on a spring day.

28:32 Soon, thousands of men started wearing them.

28:35 Though t-shirts go back to the 19th century, now we have all adjusted to the comfort of

28:40 our cozy t-shirts.

28:42 Do you also wear t-shirts like the sailors?

28:48 So grocery carts have loops for a reason.

28:51 You don't want to put your jacket in your cart next to a bunch of potatoes and onions,

28:55 do you?

28:56 Hang it on the loop instead – it's there to help you organize your cart better.

29:01 Carts also have a cool section at the bottom.

29:04 Whenever your cart's full, just lift it up and attach a shopping basket for extra

29:08 purchases.

29:10 Lift up the whole metal thing, sit your basket on the horizontal bar above the wheels, and

29:15 secure it with those handy hooks.

29:18 If you've got some pesky parsley stuck in your teeth, try this tip.

29:22 It can be hard to get it all out with loose floss.

29:25 You need more tension – just tie it in a knot.

29:29 Toothpaste stripes may seem a bit weird.

29:31 It's just a marketing trick.

29:34 Back in the 70s, a leading toothpaste brand added a blue stripe to show that their toothpaste

29:39 had double action.

29:41 Solid white toothpaste worked just as well.

29:44 But those blue bristles on your toothbrush actually make sense.

29:49 They gradually lose their color over time.

29:52 When the blue's faded, it's time to change your toothbrush.

29:56 Ever notice that tiny hole on the bottom of a padlock?

30:00 Its hidden purpose is to drain water out, to keep it from rusting.

30:04 It's also the place to lubricate a padlock.

30:07 A drop of oil in there will make it open and close way easier.

30:12 Those ridges on the edge of dimes aren't just for show.

30:15 People used to shave off the edges, then melt the edges down into new coins.

30:20 But thanks to the new design, it's easy to tell if someone's been shaving the edges

30:25 off.

30:27 If you still struggle with peeling an orange, here's another way of opening it.

30:31 First, cut off the top and bottom.

30:34 Make a slit on the side and pull it open.

30:37 That knobbly bit sticking out of the cap of your favorite cream is there for a reason.

30:42 These tubes are usually sealed with foil.

30:45 So unless you love breaking your nails trying to open them, just flip the cap over and pull

30:50 and push.

30:52 The tiny rubber disc under every bottle cap isn't just for seeing if you want a lifetime

30:57 supply of soda.

30:59 It's what keeps your drink all nice and bubbly.

31:02 The lid keeps the liquid inside.

31:04 The rubber disc keeps the gas inside.

31:07 Until you drink it.

31:09 If you use the blue side of your eraser to erase pen, your notebooks are probably all

31:14 full of holes.

31:16 The blue side's there for when you need to erase something on much thicker paper.

31:20 It works on pencil and even ink, as long as the paper's thick enough.

31:25 Your bobby pins might not stay in place if the grooves aren't facing the right way.

31:30 They should always be on the bottom, close to your head.

31:34 Still coming loose?

31:35 Put a squeeze of hairspray right onto the bobby pin before you put it in your hair.

31:42 Many glass bottles usually have some sort of indent at the bottom.

31:46 It's handy if you want to be fancy.

31:48 Put your thumb in the indent and pour away.

31:52 The technical name for this little dude is a punt.

31:56 Those sugar sticks at your local coffee stand are ready to be opened in a new and easier

32:01 way.

32:02 Look how happy they are!

32:04 Try splitting it right down the middle.

32:06 No more sugar on your fingers, no more tiny little paper bit, even your coffee's happier!

32:12 Your cotton rounds pack has those strings on it so you can hang it on a handy hook in

32:17 the bathroom.

32:18 But there's no need to loosen and tighten back up again every time.

32:23 Check out the bottom of the pack – it has a perforated line.

32:27 Tear it open carefully, and you're good to go.

32:31 Doorknobs are usually made of brass, bronze, or some other copper alloy.

32:35 Why?

32:36 They're antibacterial, so they stop microbes from spreading.

32:41 Just a couple of hours, and the pesky microbes are gone.

32:44 But don't forget to wash your hands anyway!

32:48 Bottles have long necks for a reason.

32:50 Hold the neck, not the bottle, if you want to enjoy a cold drink.

32:55 Two zips too much?

32:57 Maybe.

32:58 But they come in handy as a clever anti-theft device.

33:01 Just lock them together.

33:03 Now no one can open your backpack.

33:05 Don't have a lock on you?

33:07 You can also tie them together with some string, or even just a paper clip – anything to

33:12 slow those pickpockets down.

33:15 That tiny little button on the back of a shirt collar is used to hold your tie in place.

33:20 You don't want your tie trying to escape back there.

33:24 Shoe manufacturers care about their customers.

33:27 So most running shoes now have a special anti-blister system, pre-installed.

33:34 Sounds intense, but it's basically just that extra hole on top of your sneakers.

33:39 Make a loop with the extra hole, inserting the lace backwards.

33:43 Cross your laces and put them through the loops.

33:46 Now pull the laces down to lock your foot in place.

33:50 Now run!

33:51 You'll find silica gel packets when you buy bags, shoes, even some snacks.

33:57 Don't throw them away!

33:59 They soak up excess moisture, so any times your shoes are a bit damp, chuck a few gel

34:05 packets in there overnight.

34:08 You might've been using your shampoo wrong this whole time.

34:11 Really!

34:12 Here's the gist.

34:13 Don't apply it to your hair.

34:15 Just apply it to the roots.

34:17 The foam you create will trickle down on your hair anyway.

34:21 Notebook margins aren't for taking extra notes or practicing emojis.

34:25 They were invented to protect people's work.

34:28 People used to live with a lot of hungry rats around.

34:31 The rats would nibble at the paper, eating people's work.

34:35 They put the margin lines there to let people know to start their writing further from the

34:40 edge so it's not lost to a hungry rodent.

34:44 Solo cups are the key element for any barbecue party.

34:48 But these red cups are even cooler than you thought.

34:51 You can use them to measure liquids.

34:53 The bottom line equals 1 ounce, the second line equals 5 ounces, and the third line equals

34:59 12 ounces.

35:01 You're traveling by plane overnight and just can't get to sleep.

35:05 And the first night in a hotel wasn't great, regardless of how comfy the bed was.

35:11 This is because of a human evolutionary trait called the first night effect.

35:16 When you sleep in a different place than your home, the left side of the brain responds

35:20 to more sounds while you're asleep.

35:23 It continues to analyze your surroundings without you realizing, acting as though it's

35:27 on a night watch and keeping you alert for any potential dangers.

35:32 Most animals have this trait, although it's a lot more subtle in humans.

35:37 But it's still effective enough to make sure you get your peanuts.

35:42 Before playing basketball with hoops, you would have instead been playing with peach

35:46 baskets.

35:47 When the game was invented in 1891, a peach basket was used, with the bottom of it cut

35:52 off.

35:53 But it only took 15 years for players to grow tired of constantly collecting the jammed

35:57 balls and to remove the basket altogether.

36:01 When you click your fingers, the snapping sound isn't from the physical click of finger

36:05 and thumb.

36:07 The noise actually comes from the finger hitting the palm.

36:12 The instant film for the first Polaroid cameras didn't have their own coating after taking

36:16 a photo.

36:17 To develop it, you applied it yourself.

36:20 Waiting for it to dry took a long time, so shaking it sped up the process.

36:25 Then from the 1970s, the film provided everything required for the photo to develop, making

36:30 the popular craze of shaking Polaroids pointless.

36:34 Shaking the photo can cause the ink to wave or blur before drying properly, so you shouldn't

36:39 actually shake it like a Polaroid picture, and just wait patiently instead.

36:45 Bug spray doesn't repel all bugs, especially the worst of them all, mosquitoes.

36:50 It does cover the scent of carbon dioxide, which is what attracts mosquitoes.

36:55 But the spray only protects you for a short distance.

36:59 Mosquitoes can also track carbon dioxide over long distances.

37:03 They will continue to stalk you until they find a gap in your invisible bug shield.

37:09 A great alternative is lavender, which contains linalool.

37:13 This fragrance completely overloads the mosquito's senses, making it unable to track you.

37:19 The half-belt on the back of some jackets appear like a fashion accessory.

37:23 It was initially designed that way for larger jackets, as they could also be used as a blanket

37:28 to wrap around oneself.

37:31 The belt's position helps hold the material together, so it's easier to walk with whilst

37:35 keeping you warm.

37:37 Ketchup wasn't originally intended to be your favorite condiment.

37:42 In 1834, a physician John Cook sold ketchup as a cure for indigestion.

37:48 It was an immediate hit, and today, 10 billion ounces are purchased annually in the USA,

37:55 although not as the intended medicine.

37:58 Thomas Edison made over 1,000 inventions, and one in particular, the light bulb, is

38:04 most famously linked to him.

38:06 However, he didn't actually invent it.

38:09 Warren Delarue, a British chemist, had solved this scientific challenge 40 years earlier.

38:15 There were also 20 other inventors who made alternate versions before Edison did.

38:20 But earlier varieties relied on cotton thread and only lasted up to 14 hours.

38:26 Edison, in 1880, used a carbonized bamboo thread instead, and his worked up to 1,200

38:33 hours.

38:34 It became the most commercially viable light bulb, and today's ones are similarly shaped

38:38 to Edison's original.

38:41 The first treadmill was used in England in 1818.

38:45 It was a large wooden cylinder with a handrail, although it wasn't used to keep fit.

38:51 Convicted criminals would be forced to use these for up to 10 hours per day as a punishment.

38:57 The energy output potential was realized, and soon it was built to work with water pumps

39:02 and grain grinders.

39:04 It was so effective that it was used in all prisons throughout the country.

39:08 But in 1902, it was decided that it was too harsh and stopped.

39:13 And now, this cruel punishment is mainly found in gyms.

39:17 During the 1940s, there was a shortage of cocoa, and it was important to find a solution

39:22 to this problem.

39:23 A production company found a way by mixing only a small amount of cocoa with hazelnuts

39:29 and milk, and the original Nutella was created.

39:33 It started out as a loaf spread, like a stick of butter.

39:36 It then transformed into a creamier version inside a jar in 1951.

39:41 But it wasn't until 1964 that it was given its famous name.

39:47 Your passport might be a dark shade of either green, blue, or red.

39:51 The darker color not only makes them appear more official, but is intended so that through

39:56 its journeys, the dirt that's collected is more easily hidden.

40:01 Wasabi was first used back in the 8th century.

40:05 It wasn't meant as a spicy condiment as it's served with sushi today.

40:09 Initially, it was used for its antimicrobial properties that help avoid the harmful reactions

40:14 to fish with sushi that's a bit too old.
