00:00 With selfies that invade social networks, phone manufacturers had to adapt to the way people hold their phones and use their cameras.

00:07 Apparently, most users tilt their heads slightly to the right when taking selfies.

00:12 Great, it allows you to get a more natural look, which makes the image more beautiful so that you feel better.

00:18 The cameras at the back of most phones are also on the left side.

00:22 Sorry for the lefties, this was designed for righties, who are much more numerous.

00:26 Mount Everest may attract all the attention, but Mauna Kea, in Hawaii, is technically the highest mountain in the world.

00:33 Measuring more than 10 km from its base at its top, the only thing that prevents Mauna Kea from winning the title is that it is largely underwater.

00:39 Australia is larger than the moon.

00:41 The moon has a diameter of more than 3,400 km, while the width of Australia, from one coast to the other, is almost 4,000 km.

00:49 Although it is smaller, the moon gains on the plan of the surface, with more than 38 million square kilometers.

00:54 Anathedaephobia is the fear that at any time, somewhere in the world, a duck or a gull can look at you.

01:00 The person who suffers from it is not necessarily afraid that the duck or the gull is too close to it, or even that it touches it.

01:06 They just don't like the feeling of being observed.

01:08 This phobia was first described in a comic strip to show that everyone can be afraid of anything.

01:15 Anything can become a phobia. It is true that a duck that observes any of your movements would certainly give you goose bumps.

01:20 Crows are rather gifted at recognizing people's faces, and it has even been found that they remember it for a long time.

01:26 It can be a good or a bad thing, depending on your kindness towards them.

01:31 You wouldn't want to run into a crow that hates you.

01:33 Besides, you probably won't be able to recognize it.

01:36 So it's better to play it safe and give them all a little hand.

01:40 In the city of Yoro, in Central America, they have an annual event known as "fish rain", which is not optional.

01:46 Each year, in May or June, a torrential rainstorm crosses the city, leaving behind an incredible amount of fish in the streets.

01:54 It is thought that this phenomenon is caused by water storms or water tornadoes that transport poor fish far from home.

02:00 Free seafood delivery? Why not.

02:02 A photon, the most elementary part of light, takes thousands, if not millions of years to travel from the core of the sun to its surface.

02:10 But it takes only 8 minutes and 20 seconds on average to get to your eye, once it is at the surface.

02:16 This means that the light from the sun we see is very ancient, older than the human race itself.

02:21 There are only 4 words in the English language that end with "does".

02:25 Tremendous, horrendous, stupendous and hazardous.

02:29 If you have to find rhymes, you're in for it.

02:32 A single strand of spaghetti on your fork has a name.

02:35 It's called a "spaghetto".

02:37 In the Italian language, an "i" at the end of the word means it is in the plural, while a "o" indicates the singular.

02:43 And this goes for all kinds of pasta, like gnocchi instead of gnocchi, fettuccine instead of fettuccine, and ravioli for one of its divine goodness.

02:52 Eating the sticker of an apple, a peach or a pear by accident should not worry you out of measure.

02:58 They can be eaten, even if they are not really edible.

03:01 They will simply leave your body, like everything else.

03:03 The glue used to stick them is regulated by the health authorities.

03:06 But it is still recommended to wash the fruit and remove the sticker before biting it.

03:11 Dolphins don't have names for each other, but they call their friends by their names.

03:16 Which brings us to the question of what names dolphins have for us when we go into the water.

03:21 Look, Frank, these bald monkeys are back in the water.

03:24 The German chocolate cake is one of the most delicious cakes ever, but it has nothing to do with the country.

03:30 It is named after an American baker named Samuel German, who invented this delicious dessert in 1852.

03:37 The Eiffel Tower can be 15 cm higher during the summer because of the thermal expansion.

03:42 When the iron warms up during the very hot days, the iron particles expand and take up even more space.

03:48 Two planets in our solar system rotate in the opposite direction of the others.

03:52 Venus and Uranus rotate in the opposite direction.

03:55 Venus also has the longest day of all the planets in our solar system,

03:58 since it rotates every 243 terrestrial days.

04:02 A baby macaw bears the adorable name of Puffling.

04:06 To feed its puffling, the mother macaw puts about 10 fish in its beak at a time.

04:10 While you sleep, you can't smell anything, even very bad or very strong smells.

04:15 Our sense of taste and odor are reduced by 50 to 20% during flights.

04:20 This is why the food on planes is always a bit bland or too salty.

04:23 Or it's a very practical excuse for airlines.

04:26 Watch any ad for a watch, and the time displayed should be 10.10am.

04:32 It's because of the positive effect of this position of the hands.

04:35 It looks like a smile, and usually, the brand of the watch is directly under 12.

04:40 The longest English word has an incredible length of 189,819 letters.

04:45 We're not going to go all in here, but it's the full name of the big protein, nicknamed "titine".

04:50 To say it out loud, it would take more than 3 hours, so take a nap and sit back comfortably,

04:55 because we're going to have some for a while.

04:57 "Bird", with its 6 letters, is the shortest word in the French language, which contains the 5 main vowels.

05:03 The green balls can bounce higher than the rubber ones.

05:06 When a rubber ball hits a surface, it deforms before getting back to its original shape.

05:11 And a lot of energy is lost in this process.

05:13 A green ball doesn't compress at all and keeps a large part of its energy to bounce upwards.

05:19 Here's a scoop. Kangaroos can't walk backwards.

05:22 Their long feet and their heavy tail make this movement impossible.

05:25 They can move from side to side with incredible agility,

05:28 but jumping backwards is impossible because of this big muscular tail.

05:32 The most lonely creature on the planet is a whale that's been looking for a partner for a long time.

05:37 Researchers have identified its abnormally high call decades ago,

05:40 and we think it never got a response.

05:42 The unknown whale is called "lonely" because it communicates at a frequency

05:46 that is not used by any other whale in the Pacific Ocean.

05:49 How sad.

05:50 Meanwhile, the green bird can imitate almost all the sounds it hears,

05:54 including a trombone.

05:56 Australian species don't just copy other birds, but also other animals,

06:00 like koalas and dogs.

06:02 In captivity, they also copy artificial sounds,

06:04 like car or truck alarms and trumpeters.

06:08 Sorry to tell you this, but money isn't really made of paper,

06:11 which also proves that it doesn't grow on trees.

06:14 American banknotes, for example,

06:17 are made of 25% linen and 75% cotton.

06:20 That's why they have such a distinct texture and look.

06:23 In the 19th century, money was made of paper,

06:26 so people could easily counterfeit it, unlike today.

06:31 The Eiffel Tower is almost 15 cm higher during the summer.

06:35 When you heat a substance, its particles start to move more actively

06:39 and occupy a larger volume.

06:40 This is called thermal dilation.

06:43 When the temperature drops, the substance contracts again.

06:46 This effect is more important in gases,

06:49 but it can also be seen in liquids and solids, including iron.

06:53 This is why, when we build large structures, like bridges,

06:57 we use dilation joints.

06:59 They allow the structure to have a certain margin of maneuver

07:02 to dilate and contract, and these changes do not cause any damage.

07:07 Honey can last thousands of years without deteriorating.

07:11 Bees land on flowers to collect the sweet nectar.

07:14 Then they transport it to their hives and transfer it to other worker bees.

07:18 These reduce the nectar's water content by swallowing

07:22 and squeezing the liquid several times.

07:25 Yum! Bee vomit!

07:26 Special enzymes in their stomachs break down the nectar's glucose

07:31 and it becomes more acidic.

07:32 Bees drop this nectar into the hive

07:35 and start to lift it with their wings so that the water evaporates faster.

07:39 Honey is now very acidic and water-poor,

07:42 which preserves it from deterioration.

07:45 Bacteria that cause food deterioration cannot survive in such conditions.

07:50 In the past, people did not lift their mattresses from the ground.

07:53 This practice began in ancient Egypt and continued in many other cultures.

07:58 People realized that it was colder on the ground

08:01 and that they could heat their beds more easily if they were not directly in contact.

08:05 In the past, houses also had more air flow.

08:08 The cold air entered through the bottom of the doors.

08:10 There was no central heating, so people had to find other ways to warm up.

08:15 However, the hot air tended to rise, so by placing their bed higher,

08:19 it was not as cold as on the ground.

08:20 In addition, this way, they could keep their beds clean more easily.

08:24 Indeed, in modest homes, the floors were much dirtier than today,

08:28 and all this dirt generally migrated into the beds.

08:31 Speaking of cleanliness, do you think people are naturally clean and tidy?

08:35 After all, our ancestors, who lived thousands of years ago,

08:39 already used latrines and combed their hair with combs,

08:42 and they kept their interiors and bodies clean.

08:46 Our natural need for hygiene and cleanliness is motivated by our sense of disgust.

08:50 It is this mechanism that helps our body to remain safe

08:53 and protects it from various infections.

08:56 This is why we are more sensitive to certain smells and certain things.

08:59 But we still have rather unhealthy habits.

09:02 For example, eating a nanka over a keyboard.

09:05 Burk!

09:06 But some animals are even more well-groomed than us.

09:10 The rattlesnake, for example, likes to keep their environment well-organized.

09:13 Some of them even use their muscular necks and triangular heads

09:17 to sweep the dirty grass when they hunt.

09:19 Many animals like to clear their path when they go in search of their future meal,

09:24 and reptiles are one of them.

09:25 Less vegetation increases their chances of catching food.

09:29 Birds also like to clean up and get rid of uneaten food,

09:33 eggshells and any other waste in their nests.

09:36 In this way, they also make them less visible to their predators.

09:40 Meanwhile, in space, the shadows are darker on the Moon than on our planet.

09:44 This is because the Earth's atmosphere scatters more sunlight.

09:48 But if you could visit the Moon,

09:50 you would see shadows so dark that you could not see where you are going.

09:54 You would also notice footprints on the lunar surface.

09:58 Humans have not set foot on it for a few decades,

10:01 but the footprints seem to have been left only yesterday.

10:04 As there is no water or wind on the Moon, nothing can erase these footprints.

10:09 They can therefore remain there, in their original form, for millions of years.

10:14 The core of the Earth contains enough gold to cover the entire planet.

10:18 And if you decide to do it, the level of this precious metal would reach the height of your knees.

10:23 For thousands of years, people have been exploiting gold and platinum,

10:27 as well as a lot of other precious minerals, under the surface of our planet.

10:31 This is why we may have exhausted some minerals in certain regions.

10:35 But the Earth still has a huge number of these deposits, especially as it approaches its core.

10:40 It is because of the countless meteorites that collided with our planet during its formation period.

10:46 These meteorites contained different minerals, including gold.

10:50 At the time, the Earth was still in a state of fusion.

10:53 This is why most of the gold, a heavy element, sank deeply into its core.

10:57 And the silicate mantle, which is above the core,

11:01 has trapped colossal amounts of gold and other minerals.

11:04 Unfortunately, most of them are clearly out of reach today,

11:07 as we are talking about 2,900 km below the surface and temperatures of several thousand degrees.

11:14 If you were about to go into space,

11:16 one of the first things you would think of would undoubtedly be your space suit.

11:21 But do you know that it is possible to survive in space even if you do not wear any protection?

11:26 Well, don't worry, you won't last more than 15 seconds.

11:30 It's the time you need to lose consciousness, because oxygen will no longer reach your brain.

11:36 In 1965, a technician accidentally depressurized his suit inside an empty room.

11:42 He lost consciousness after 12 to 15 seconds.

11:46 27 seconds later, his suit was fortunately repressurized.

11:50 The man later said that he remembered that the moisture on his tongue was starting to boil.

11:54 He also lost his sense of taste, and he only came back to himself four days after the accident.

12:00 You can't hold your breath in space either, so it won't save you.

12:04 Your lungs would eventually break at some point, because the air inside would expand.

12:09 The oxygen in other parts of your body would also start to expand,

12:12 which means that you would inflate up to twice your normal size.

12:16 A bit of a latent Harry Potter marge.

12:19 It is only thanks to your elastic skin that you will not explode.

12:22 It will continue to hold you in one piece,

12:25 and the liquids in your body will also start to evaporate quite quickly.

12:29 We're having fun here, aren't we?

12:32 Supermarket trucks have a loop for a good reason.

12:35 You don't want to leave your jacket in your truck,

12:38 next to a filet of onions and potatoes, do you?

12:41 Hang it on the ring. It's made to help you organize your truck.

12:45 They also have another storage area at the bottom.

12:47 When your truck is full, just lift this part and put a small basket for additional purchases.

12:53 Lift the metal rod, put your basket on the horizontal bar above the wheels,

12:58 and secure it with these hooks.

13:01 If you have parsley stuck between your teeth, try this trick.

13:04 It can be difficult to remove it with a loose dental floss.

13:07 You need more tension, so tie a knot.

13:11 The stripes on the toothpaste can look a bit strange.

13:14 It's just a marketing trick.

13:16 In the 1970s, the leading toothpaste brand on the market added blue stripes

13:21 to indicate that its toothpaste had a double action.

13:24 The white toothpaste pads work just as well.

13:28 However, the blue stripes on your toothbrush are there for a good reason.

13:31 They gradually lose their color over time.

13:34 When the blue has disappeared, it's time to change your toothbrush.

13:38 Have you ever noticed this little hole under the pads?

13:40 It's there to drain the water, and it prevents the pads from rusting.

13:44 It's also a place where you can lubricate it.

13:47 A drop of oil will make it open and close much more easily.

13:51 These stops on the side of the coins are not there for nothing.

13:55 Previously, we rounded the edges, then melted them to create new pieces.

13:59 But thanks to these patterns, we can easily see if someone cut the edges.

14:04 If you have trouble peeling an orange, here's another method.

14:08 First, cut the top and bottom.

14:10 Make a notch on the side and pull to open it.

14:14 This little metal stopper that you see at the orifice of your favorite cream is there for a reason.

14:19 These tubes are generally sealed with aluminum foil.

14:22 So unless you want to break your nails trying to open them,

14:26 turn the cap over and push it.

14:29 The little rubber disc under each metal bottle cap

14:33 is not used to reveal if you've been drinking soda all your life.

14:36 That's what keeps your drink tasty and fizzy.

14:40 The cap keeps the liquid inside,

14:42 and the rubber disc keeps the gas inside.

14:45 Until you drink it!

14:48 If you use the blue part of your eraser to erase pencil on paper,

14:52 your notebooks will probably be full of holes!

14:54 The blue side will be used to erase on much thicker paper.

14:58 It works with pencil and even ink,

15:00 provided the paper is thick enough.

15:03 Hair clips will never stay in place if the waves are not on the right side.

15:08 They should always be facing your head.

15:11 You still can't do it?

15:12 Put a little lacquer on your clip before putting it in your hair.

15:16 Many bottles of beer have a kind of indentation on their base.

15:21 It's convenient if you want to look classy while pouring your drink.

15:24 Put your thumb in the indentation and pour.

15:26 On wine bottles, that's what we call "picking".

15:30 These little sugar cubes from the local café only ask to be opened differently.

15:34 Look how happy they are!

15:36 Try to tear the packaging in the middle by opening it.

15:38 No more sugar on your fingers, no more little paper hanging,

15:41 and your coffee is also happier.

15:44 The packaging of the cotton discs has a string that allows you to hang it

15:48 on a hook in your bathroom.

15:49 But you don't need to loosen and tighten the string every time you take a disc.

15:54 Look at the bottom.

15:55 There is a line ready to be cut.

15:57 Tear it to open it, and voilà!

16:00 Door handles are usually made of brass, bronze or copper alloy.

16:04 Why?

16:05 It's antibacterial, so it prevents microbes from spreading.

16:09 In a few hours, the bad microbes are gone.

16:12 But don't forget to wash your hands, whatever it is.

16:15 Bottles have a long neck for a good reason.

16:18 You should hold the neck and not the bottle, if you want to enjoy a good fresh drink.

16:23 The same goes for the glass on foot.

16:25 The foot prevents your drink from overheating.

16:29 Two zips is too much?

16:30 Maybe, but it's very useful against theft.

16:32 Just lock them together.

16:34 No one can open your bag.

16:36 You don't have a lock with you?

16:38 You can also assemble them with a string, or a trombone,

16:41 or anything that can prevent pickpockets from succeeding.

16:44 This little button on your neck on your shirt is for holding your tie in place.

16:49 It shouldn't slip out.

16:51 Shoe manufacturers are loyal to their customers,

16:54 so most running shoes now have a pre-installed anti-bubble system.

16:58 It may seem a bit exaggerated, but it's actually the extra hole at the top of your shoes.

17:03 Put your lace through the extra hole, by inserting the lace in reverse.

17:07 Cross them and put them through the loops.

17:10 Now tie a knot, as usual, and go for a run.

17:14 If you find small bags of silica gel in your bags, shoes or other things, don't throw them away.

17:19 They're there to absorb the excess moisture.

17:22 So as soon as your shoes are a bit wet,

17:24 put a few packets of gel in them and leave them overnight.

17:28 You may have been using your shampoo badly all this time.

17:31 Here's a tip.

17:32 Don't apply it all over the length of your hair,

17:34 but only on the roots.

17:37 The foam created will flow along your hair.

17:40 The margins left in the notebooks are not made to take extra notes,

17:44 or to practice making emojis.

17:46 They were invented to protect the work of individuals.

17:49 In the past, we lived among lots of hungry rats.

17:53 They devoured the paper.

17:54 So we put these margins in so that people remember to start their work from the margins,

17:59 so that they're not lost, devoured by a rat.

18:02 American goblets, called solo cups, are a key element for any party.

18:07 But they also have the advantage of being a green-doser, to balance out your drinks.

18:12 The bottom line indicates 30 ml.

18:14 The second line is 148 ml,

18:16 and the third line is 355 ml.

18:20 If you like to put milk in your tea,

18:22 try this trick next time.

18:24 Pour it by putting the hole up.

18:27 It will splash a lot less, and it's easier to control.

18:30 The headrests are quite comfortable,

18:32 and the detachable ones are there for your safety.

18:35 If you remove the headrest, you'll see two solid metal bars.

18:39 If you're stuck or locked in a car,

18:41 You can always remove the bars to break the window and escape.
