00:00 Okay, here's the first one.

00:02 Myth or true?

00:04 Carrots can help you see in the dark.

00:06 Myth.

00:07 While carrots are full of vitamin A, which helps maintain eyesight, you won't get night

00:12 vision.

00:13 In the 1940s, British Air Forces invented a new radar, and to keep it secret, they told

00:18 everyone it was carrots that helped them see at nighttime.

00:23 Diamonds aren't a special gemstone.

00:25 True.

00:26 While diamonds may be a great engagement rock, they're not as rare as we've been made to

00:30 believe.

00:31 Advertising campaigns have made this very common rock something extraordinary.

00:36 If you want something really rare, pain-eye gems will look beautiful and empty your wallet

00:41 at the same time.

00:43 Around $50,000 a carrot.

00:47 Fruit loops have different flavors.

00:50 Myth.

00:51 There's no point in avoiding the color you don't like.

00:54 All the colors are the same flavor.

00:56 And Kellogg's has stated that they all share the same blended fruit flavor.

00:59 Well, now I don't know what to believe anymore.

01:04 Dropping a penny from the Empire State Building can obliterate a person below.

01:08 Myth.

01:09 While the penny won't tickle, it will not damage anyone on the ground.

01:13 Simply, the penny can't build up enough speed while it's tumbling to the ground.

01:18 Better to just keep the change in your pocket.

01:23 The moon has a dark side.

01:25 Myth.

01:26 No, the moon isn't going to use the force to rule.

01:29 Our satellite is tidally locked with the Earth, meaning that we're always looking at one

01:34 side.

01:35 But there's no permanent dark side.

01:40 Kleenex was originally designed for gas masks.

01:43 True.

01:44 Yeah, Kimberly-Clark originally designed a thin cotton substitute to be used as a filter.

01:51 In 1924, Kleenex began selling in the US as a cold cream and makeup remover, eventually

01:57 turning into the soft tissues we love today.

02:01 Chocolate is bad for you.

02:03 Boy, isn't that a myth.

02:05 While too much chocolate, just like too much of anything, can indeed do some harm, a little

02:10 bit can be quite good for you.

02:12 Not just any chocolate, though, only the dark variety.

02:16 Yum.

02:18 And sleep-ins will help you catch up on lost sleep.

02:21 That's a myth.

02:22 As comfy as your bed is on a Sunday morning, you just can't make up for lost sleep.

02:27 Irregular sleep can lower your concentration and performance.

02:31 If you're refreshed when you wake up, you've had the right amount.

02:37 Zombies are real.

02:38 True.

02:39 Now, no human has ever turned into a hungry zombie that we're shown so much in the movies,

02:45 but they do exist in the animal kingdom.

02:47 A fungus that has a really long name I don't want to pronounce takes over ants with its

02:52 chemicals.

02:54 Under the control of the fungus, the ant leaves its family to find a very specific branch

02:59 or leaf.

03:00 Then, it lets the fungus sprout out of it and release spores back into the world.

03:05 How delightful.

03:07 The largest living organism is the blue whale, African elephant, or shak.

03:12 Myth.

03:14 While all of those are large, the honey fungus in the Blue Mountains, Oregon, wins by quite

03:19 a bit.

03:20 With the length of 3.4 miles, that's 6.5 Burj Khalifa's end-to-end and it's still

03:26 growing.

03:27 But on the bright side, it's edible.

03:29 Mushroom omelet, anyone?

03:32 Turkeys can blush.

03:34 True.

03:35 Just like humans, turkeys blush when excited, angry, or sick.

03:39 The skin on their heads and necks can turn red or even a shade of blue.

03:44 The fleshy flap of skin that hangs over their neck is called a snood.

03:48 It also turns bright red when the bird is excited.

03:52 Maybe not at Thanksgiving, though.

03:54 We only have 5 senses.

03:56 Myth.

03:58 There's no right number.

03:59 Some say 5, 7, 14, 24, or even 57.

04:04 Our most basic senses are actually sight, hearing, smell, taste, and touch.

04:09 But also movement, body position, temperature, balance, and the sense of our internal state.

04:15 Like feeling your heart.

04:16 For example, close your eyes and touch your nose.

04:19 That's proprioception, or body position.

04:24 Bats are blind.

04:26 Myth.

04:27 Bats' eyesight is actually better at nighttime than ours.

04:30 They just can't see as well in daytime because they only see in black and white.

04:34 Perhaps this myth arose from the fact that bats use sonar to navigate without sight.

04:41 Unicorns are real.

04:42 True.

04:43 They're not horses, though.

04:45 It's deer that are likely the culprit.

04:47 A single horn can be a genetic anomaly found in some species, possibly leading to the unicorn

04:53 legend that formed a long time ago.

04:57 Honey never spoils.

04:59 Myth.

05:00 Uncovered in a humid environment, it will spoil.

05:04 As long as the lid stays on it and no water is added to it, honey shouldn't go bad,

05:09 though.

05:10 Having antifungal and antibacterial properties means no organisms can live in it.

05:15 No matter how old your stored honey is, it's probably perfectly edible.

05:21 Oranges are always orange.

05:23 Myth.

05:24 White oranges are a hybrid of tangerines and the pomelo, with a bright green skin to

05:29 help protect them from the sun.

05:31 In warmer climates, like Southeast Asia, oranges are still a bright green when ripe.

05:37 Makes you wonder what came first, the fruit or the color.

05:41 There are bugs in your strawberry frappuccino.

05:44 True.

05:45 But not anymore.

05:47 A dye made of ground-up tiny insects called cachanil bugs is used by many companies to

05:53 make the color red.

05:55 Starbucks stopped using bug red color in their strawberry frappuccinos in 2015.

06:02 Firefighters use wetter water.

06:04 True.

06:05 To be more efficient at stopping fires, firefighters recently started adding certain chemicals

06:10 to the water.

06:12 The wetting agents reduce the surface tension of the water, making it easier to spread and

06:16 soak into objects.

06:19 Leave wasps alone and they'll leave you alone.

06:22 Myth.

06:23 While this works for bees, their cousins, the yellow jackets, will disagree.

06:28 Known as one of the most bad-tempered wasps, they've been said to sting unprovoked, even

06:33 if you just happen to walk by their nest.

06:36 If you see wasps, give them a wide berth.

06:40 The Eiffel Tower was supposed to be torn down after 20 years.

06:44 True.

06:45 The Eiffel Tower was designed to show off France's industrial power during the World's

06:50 Fair.

06:51 The designers cleverly put transmitters and antennas on top to make the tower too useful

06:56 to eventually demolish.

07:00 Head lice prefer dirty hair.

07:03 Myth.

07:04 Lice don't really think about hair cleanliness.

07:06 They simply need human hair to hang onto, whether it's squeaky clean or greasier than

07:11 a fryer.

07:13 Lice feed off of our scalps, and the hair is just a place to hang out.

07:18 Camels' humps store water.

07:20 Myth.

07:21 Camels don't store water.

07:23 They store fat in their tissues.

07:25 Just like me after the holidays.

07:27 These reservoirs of fat allow camels to survive for days in the desert without stopping for

07:32 food.

07:33 They drink large amounts of water at a time and store that in their bloodstream.

07:39 You need to drink 8 glasses of water a day.

07:43 Myth.

07:44 Staying hydrated is critical, especially in hotter weather.

07:47 But we seem to forget that every drink is mainly water, even tea and coffee.

07:52 Our bodies are the best indicators for when to drink water.

07:56 Feel thirsty?

07:57 Then it's time to have a drink.

08:01 An elephant never forgets.

08:03 True.

08:05 Having the biggest brain of all land animals, elephants should have a great memory, and

08:10 they do.

08:11 Being able to remember their entire territory, friends, and spots to find water is crucial

08:17 to the social structure of elephants.

08:19 They might even have a better memory than you and I.

08:22 Now where did I leave my keys?

08:26 Bananas grow upside down.

08:28 True.

08:29 Bananas grow naturally towards the sun as they're getting larger.

08:33 That's why there's a curve.

08:34 So does that mean we've been peeling them the wrong way this whole time?

08:39 Maybe.

08:41 No number before 1000 contains the letter A.

08:44 True.

08:46 Now you can try and spell each number out if you like, but I bet you're just gonna

08:50 take my word for it.

08:55 The Guinness Book of World Records was created to settle arguments.

08:59 True.

09:00 The world's best trivia book was published in 1955 after an argument about the fastest

09:06 game bird in Europe.

09:07 The managing director of Guinness Brewery realized there wasn't a go-to book for trivial

09:12 questions so he created his own, and the rest is history.

09:18 You're eating real wasabi.

09:20 Myth.

09:21 When you're sitting down for tasty sushi, that green paste sometimes isn't wasabi,

09:27 it's horseradish.

09:29 Real wasabi is very expensive with a milder taste to it.

09:32 If it's not made in front of you, it's not going to be the real thing.

09:36 So there.

09:40 Did you know that chickens can jump and fly too?

09:44 Domestication of the chicken dates back to at least 2000 BCE.

09:48 They do have the required feathers and muscles to fly, but they don't do it much anymore

09:52 hundreds of years after they were domesticated.

09:55 But if you give them the right motivation, they can do that.

09:59 If they think the other side of the fence is cool, they can jump up to 6 feet.

10:04 Some hens hop on the trees to roost.

10:07 Picture a tree with a couple of chickens on it.

10:09 Looks so funny.

10:11 Their motivation is safety.

10:13 The tree serves as a cover for them in the daytime and protects them from winged predators.

10:18 Similarly, at night, the tree turns into a shelter from wind and rain and the possible

10:23 attacks from ground predators.

10:26 This doesn't have to be in the wild.

10:28 Farms where chickens can wander around freely also have tree nests.

10:32 Some sneaky chickens leave their coop and jump onto the trees.

10:36 So many chicken owners search for ways to keep them under control.

10:39 Hey Siri, search for "How to deal with jumping chickens".

10:44 I'm now moving on to everyday items and the secrets they held.

10:48 The twist ties and plastic bags on bread packs don't have random colors.

10:53 They are color-coded based on the daily bread baked.

10:57 Each day of the week has an assigned color.

10:59 For example, blue twist tie stands for Monday, green for Tuesday, and red for Thursday.

11:05 Now you can figure out how fresh your bread is.

11:09 Color codes are helpful for employees too.

11:11 They can easily spot the old loaves on the shelves.

11:15 There's a popular saying, "You are what you eat".

11:18 It turns out that our guts are also there to make us happy.

11:22 Serotonin is the feel-good hormone.

11:24 It's also a neurotransmitter.

11:27 Many of us immediately associate it with our brains.

11:30 But interestingly, around 95% of the body's serotonin is produced in our digestive tract.

11:38 Many of us often use the words "herbs" and "spices" interchangeably.

11:42 But these are different seasonings.

11:44 Spices come from every part of a plant or tree, like root, seed, or bark.

11:49 But herbs are the plant's leaves.

11:52 We generally add spice to food in roasting and during cooking.

11:56 Herbs release their aroma faster, so we add them at the very end.

12:00 Do you ever feel you've been watched and discovered that you're right?

12:04 Well, that spider-sense-like feeling is called gaze detection.

12:09 Your brain senses when someone is staring at you.

12:12 Research explains this as a sort of defense mechanism.

12:15 A direct gaze can be a symbol of dominance, and that can be a potential threat.

12:20 Humans evolved with this feeling in time.

12:23 Strangely, it works when the person looks right at you.

12:26 If their gaze is off just a few degrees to the left or right of you, your brain won't

12:31 react this way.

12:33 What about the urge to re-watch your favorite movies or listen to your songs over and over?

12:38 You're not alone.

12:40 This habit has some benefits for your mental health.

12:42 This behavior eases your mind.

12:45 When people feel overwhelmed, they'll have less self-control and be less motivated to

12:49 complete hard tasks.

12:51 You are drawn into The Office's first season again because when you watch, listen, or do

12:56 something familiar, you don't have to spend the effort to monitor what you're thinking.

13:00 So it's a good way to have a quick mental reset.

13:04 Here's another feeling.

13:05 Imagine you're enjoying the sunset on a terrace or at the top of the Eiffel Tower.

13:10 Out of nowhere, your inner voice whispers, "What if I jump?"

13:14 This isn't coming from a darker state.

13:16 You know, it's just sort of a feeling that appears when you're high up.

13:20 There is a name for this.

13:21 The "call of the void" or "the high place phenomenon" is a relatively new research topic,

13:27 but more studies are on the way.

13:30 Jim Carrey's great performance in The Truman Show is surely remembered.

13:34 Did you know that The Truman Show delusion is an actual thing?

13:38 The phenomenon is an issue related to cognitive neuropsychiatry.

13:43 People with this delusion believe that they're being filmed and that the footage will be

13:47 broadcasted for entertainment.

13:50 There was a time when aluminum was more precious than gold.

13:53 I know, it's hard to believe.

13:55 We now wrap our sandwiches on this everyday item.

13:58 If we go back to the 19th century, we would see aluminum as a hard-to-get element because

14:03 it was literally hard to obtain until innovators found a way to extract it on large industrial

14:09 scales.

14:10 Then the reign of aluminum was over.

14:13 There are stories about the French ruler Napoleon III having an aluminum cutlery set that he

14:17 served food to his special guests.

14:23 We might as well talk about a time travelers party held in 2009.

14:28 The theoretical physicist Stephen Hawking invited time travelers to hang out.

14:33 There was a huge banner hung up with the words "Welcome, time travelers!"

14:37 No one showed up, but maybe travelers had prior engagements and that's why they didn't

14:42 attend the party.

14:44 I swear I'm not crying because no one showed up to that awesome party.

14:47 I was just cutting an onion.

14:50 Why do we burst into tears when we chop onions?

14:53 Because of a particular enzyme.

14:55 Is there a solution?

14:57 Next time, get some damp paper towel and put it on the cutting board next to the onion.

15:02 The acidity that comes from the enzyme will go towards the wet paper instead of your eyes.

15:08 The ancient Egyptian civil calendar was quite similar to the one we use now.

15:12 They had 365 days divided into 12 months.

15:17 But instead of spreading a 31st to some months, they would add those extra days to the end

15:22 of the year.

15:25 Now let's turn our cameras to the animal kingdom again.

15:29 Is there a benefit for zebras to have their fascinating pattern?

15:33 Scientists asked this question too and experimented.

15:36 They dressed up horses with zebra look-alike coats.

15:39 The coat was covering the whole body of the horses but their heads.

15:43 It turns out that zebra patterns repel flies.

15:47 Scientists observed that flies only go for the heads of the animals and stay away from

15:51 the horse bodies.

15:56 Ants are known as hard-working animals even in the tales.

16:00 That's got a legit reflection in real life.

16:03 They can carry up to 20 times more weight than their own body weight.

16:07 These insects have other noble qualities too.

16:09 If an ant gets seriously injured, it will refuse treatment from the colony's paramedic

16:14 ant.

16:15 The ant knows that it can't make it so instead of wasting the colony's resources, this ant

16:20 forces the paramedic ant to carry on without it.

16:26 Camels can survive around 15 days without drinking water.

16:30 Many people assume that they store water in their humps.

16:32 Nope, humps are for food storage in the form of fat.

16:36 The water is kept in their bloodstream.

16:38 Speaking of camels, in some countries there is a tradition to hold camel beauty contests.

16:44 For instance, a contest was held in the 2022 World Cup in Qatar as an attraction.

16:54 You see a giant housefly in the house but it flees from your ninja's hands.

16:58 You might think that nature will take care of it in a couple of days but actually, houseflies

17:03 can live for about a month or two.

17:06 The next fact is about an emergency on the road.

17:10 Detachable car headrests can be used as an escape tool.

17:14 You can break the window with the headrests if you can't leave the car by the doors.

17:18 You should wedge the headrest between the glass and the window sill.

17:21 Aim a corner.

17:23 Then you hit the headrest as hard as you can to break the glass safely.

17:27 You might have to hit a couple of times but it eventually shatters.

17:30 Don't give up after one try!

17:33 Don't be shy, share your wow facts with us!
