00:01Good morning! I'm so happy we're going to spend the day together.
00:04You see, I stayed up reading about all those common things that you and I never realized actually had purposes.
00:11My head's brimming with all this knowledge. I need to unload it on someone, and you're the perfect volunteer.
00:17First things first, food. Gotta have a hearty breakfast. I'll make you some eggs, but before I cook them, look
00:23at this.
00:24See that little white string? There are a few common misconceptions about what it is, but no, it's not part
00:30of a baby chick or anything yucky.
00:32Even though it looks kinda unnatural, you actually want to see it in your eggs. It's called chalaza.
00:39There are two of them in each egg, and they're like the ropes that hold up a hammock, and this
00:44hammock is an egg yolk.
00:46The strings keep it from splatting against the shell. If you still don't like the look of it, don't worry,
00:51these strings usually vanish after cooking.
00:54Plus, they're a sign of freshness. If you don't see a trusty chalaza, you might have left your eggs sitting
00:59in the fridge for a few days too many.
01:01So how do you like them? Scrambled or sunny side up?
01:05Before you clear your plate, you need to add a piece of fruit to that breakfast.
01:09Want an apple? By the way, do you know where apples come from? I mean, all the apples you've ever
01:14eaten?
01:15Apple trees, right? And what seeds do those apple trees grow from? Apple seeds, right?
01:20Nope. Almost all apple trees don't grow from seeds. That's because seedlings turn out genetically different from their parent trees.
01:29Seeds from a Golden Delicious don't grow a Golden Delicious tree.
01:33All apples you've ever eaten were likely grown on grafted trees.
01:37That's when farmers attach apple branches to the cut trunk of another tree.
01:42Any other tree. Yeah, a peach tree or even an avocado tree.
01:47Frankenstein trees!
01:50Before we start our day, let's check the weather.
01:53Turn on the TV.
01:54Oh, wait. Have you ever looked closely at your couch?
01:58See those buttons?
01:59Once upon a time, furniture was filled with horse hair and straw.
02:03Those sorts of filings moved around a lot.
02:06Couches could get really lumpy and bumpy, so those deep buttons were used to lock them in place.
02:11We use more comfortable fillings than straw now, but we still keep the look for fashion.
02:18Okay, go on. You can turn the TV on now.
02:21Uh-oh. There's a 60% chance of rain.
02:24Looks like we'll need to bring umbrellas.
02:26But do you know what this forecast actually means?
02:29I've always thought it means that there's, you know, a 60% chance of rain.
02:32But this number actually means that 60% of the forecasted area might get rain.
02:40How about a quick snack for the road?
02:42Oreos! Yum!
02:43Look at the design on the top of the cookie.
02:45In the center, there's a circle topped with a double-armed cross.
02:49It's the Nabisco logo, which is a European symbol for quality.
02:55Grab a coat too, just in case.
02:57Have you ever noticed these letters printed on the zipper of your coat?
03:02Or any clothes zippers for that matter?
03:04Go on and check right now.
03:06I bet I can guess what letters you'll find there.
03:08If I'm right, you owe me a soda.
03:10Does it say YKK?
03:12I had a 50% chance of getting that right.
03:15Because about half of all zippers in the world are made by one manufacturer called the YKK Group.
03:21So do you owe me a soda or what?
03:26Let's head out.
03:27I have some errands to run.
03:28You don't mind tagging along, do you?
03:31First stop, I need to pop into the bank to drop off a check.
03:34Not all lines printed on checks are as simple as meets the eye.
03:38To make them harder to replicate, a lot of them have tiny writing.
03:42It's so small, it just looks like regular black lines, showing you where to sign.
03:47Usually, the writing is phrases like original document or authorized signature.
03:52Only superheroes with microscopic vision would know, though.
03:57On some U.S. pennies, and these coins are pretty rare,
04:01you can spot several letters under Lincoln's shoulder.
04:03V. D. B.
04:06What do they mean?
04:08They're the initials of Victor David Brenner.
04:10That's the man who designed the very first penny
04:13and the exact same portrait of Lincoln that's still in use today.
04:19Next, I need a few things from the supermarket.
04:22Can you grab a cart?
04:23Did you know that these metal loops on the cart actually have a use?
04:27They're designed to hold your grocery bags if you have too many to fit inside the cart,
04:31or if you need fragile items to stay upright.
04:35Do you need anything?
04:37Here's my shopping list.
04:381. Bubble bath
04:39What? It's an essential!
04:42You know, I'm not kidding.
04:43It actually does have a practical use,
04:45and it's not to make a bubble beard when you're bored in the bathtub.
04:49Bubble bath was invented so that the foam would sit on the surface of the water and insulate it,
04:53keeping the water warmer for longer.
04:56I like long baths, so it's very important to me.
04:59Next item, a toothbrush.
05:02Mine's old and needs replacing.
05:03The blue indicator bristles are pretty much gone.
05:06Oh, did you not know that's what they're for?
05:08Yeah, the row of blue bristles on most toothbrushes acts like a timer.
05:13Each time you brush your teeth, they get thinner and thinner,
05:15and eventually, the blue color gets all worn away.
05:19That's when you know you need a refresher.
05:21Just to be safe, I'll get you a new brush too.
05:24All right, I've got everything I need.
05:25Let's go home.
05:27Uh-oh, it started raining.
05:29Good thing we grabbed those umbrellas.
05:31It seems like no one really knows what the metal point at the top of an umbrella is for.
05:36See, now that we're out of the rain, there are water drops all over the fabric.
05:41When we fold our umbrellas up and put them in the car, they'll soak everything they touch.
05:46But not if we tap the metal tip on the ground and shake all the water off.
05:50Convenient, right?
05:52Into the car we get.
05:53That line of black dots around the windshield always bugged me.
05:56But I finally found out what it's for.
05:58It's called a frit.
06:00It shields the glue that bonds the windshield to the car from ultraviolet light.
06:04The dots, though, they just make it look nice.
06:08Let's turn on the radio and listen to some tunes.
06:11You probably see that symbol on the radio's power button pretty much every day.
06:15It's also on computers, microwaves, game consoles, and so many other things.
06:20But I never thought about what it means.
06:22It dates way back before most of the technology that uses it.
06:26Turns out it's actually binary code that says standby power state.
06:30Cool, huh?
06:33Well, those errands made me work up an appetite.
06:37Here's a deal.
06:37I'll do the dishes while you cook some spaghetti for dinner.
06:41Everyone always says it's impossible to measure out the right amount of spaghetti.
06:45It's so hard to figure out what one portion looks like.
06:48But none of us should struggle with it because there's a tool for this exact purpose right under our noses.
06:54In the middle of your spaghetti serving ladle, there's a hole perfectly sized to measure out one serving.
07:00No more leftovers from now on.
07:03Everyone always uses the tops of plates and bowls.
07:07But as I'm washing them, it reminds me of all the clever uses for the bottom sides.
07:12For example, the rough rim under plates can sharpen knives.
07:16Watch this.
07:17All of your knives are super dull and can barely cut these tomatoes.
07:21Now, if I take them and run them along the bottom of this plate a few times, voila!
07:26Fresh as new.
07:28They slice the tomatoes like butter.
07:32And this groove here in the bottom of your mug, it has a purpose too.
07:36One you'll probably be very thankful for even if you don't know about it yet.
07:40This groove is specifically designed for mugs you put in the dishwasher upside down.
07:45Without it, a puddle of water would pool inside the rim and spill all over your feet when you take
07:50the mug out.
07:51Trust me, this little gap is your best friend.
07:55Oh, before you use that frying pan, have you salted the oil?
07:59Yep.
07:59You shouldn't only salt your pasta water, but also the frying oil.
08:03A pinch of flour will also work.
08:05Both absorb the moisture from the food you put in and stop the boiling oil from splattering.
08:11But do watch out because salt might lower the temperature at which oil starts to smoke.
08:15It probably won't be an issue unless you're boiling big vats of this stuff, though.
08:20That's enough new information for one day, right?
08:23Let's finish this great day with a big spaghetti dinner.
08:29Many people believe our ancestors were monosyllabic grunters.
08:33But according to a new study from the University of Western Australia, this might not be the case.
08:39The primary purpose of any language is to convey some meaning, right?
08:43So, researchers believe that nonverbal communication most likely came before oral language.
08:50To test this, they asked a group of people to play a communication game similar to charades.
08:56They put people speaking different languages and from different cultures in one room
09:01and told them to communicate through gestures.
09:03No grunts allowed.
09:05The results were astonishing.
09:08Scientists confirmed that many gestures apparently have universal meaning.
09:13This way, people understand each other more easily than with any other type of vocalization.
09:18If I make the shape of a heart with my hands, you'll get what I mean, right?
09:24Speaking of languages, did you know that the last letter added to the English alphabet wasn't Z?
09:30It was actually J.
09:32It's also no coincidence that I and J are side by side.
09:37They started out as the same letter.
09:39J was just a prettier way of writing I.
09:42With time, J got its own phoneme and became a separate letter all on its own.
09:49Bees are fascinating creatures.
09:51They're very important for people.
09:53For one thing, it's their delicious honey.
09:55But they are the best pollinators too.
09:58We need them to keep restoring our food supplies.
10:02Some people may be afraid of their stingers, but honeybees will only sting you if they feel threatened.
10:08The worst part is that bees never survive after stinging you.
10:11These insects can't pull their barbed stinger out of your skin.
10:16And this stinger is part of the bees' digestive tract, nerves, and muscles.
10:21After losing all that, the tiny creature can't really make it out alive.
10:26The filling between Kit Kat wafers is made from other Kit Kats.
10:30When something goes wrong during the production, for example, a Kit Kat bar has too many bubbles or other imperfections,
10:37nothing goes to waste.
10:39Such sweets get melted into a paste.
10:42And then, these substandard Kit Kats are used to fill in other Kit Kat bars.
10:49Oreology is a field of science that studies Oreos.
10:53Yes, the cookies.
10:54The flow and fracture of Oreos are the subject of several scientific experiments.
11:00Researchers are doing everything in their power to answer this question.
11:04Why does all the cream remain only on one side of the Oreo?
11:08Grab an Oreo and break it apart the way you normally do it.
11:12See what I mean?
11:15Reologists are physicists who study complex fluids.
11:18After analyzing the Oreo filling, they classified it as a flowable soft solid.
11:24These are fluids that are soft when you don't disturb them and flow when they're under a large amount of
11:30stress.
11:32No, that doesn't mean Oreos are literally stressed.
11:35This means that the cream on the inside will behave according to the pressure you apply while opening a cookie.
11:41The trick that will help you distribute the cream is a simple twist.
11:45If you twist an Oreo slowly and steadily, this will reduce the stress and most likely let the cream stay
11:53on both sides of the cookie.
11:55Try it out for yourself and let me know if it works for you.
12:00Meanwhile, Oreologists have developed a special machine to do the testing.
12:04Ever heard of an Oreometer?
12:06It was designed specifically to twist Oreos at an optimum speed and angle.
12:12Way to go, cookie science!
12:14It's a beautiful afternoon and you're looking at the sky.
12:17Wait, what are those tiny dots traveling in squiggly lines?
12:21They're only visible for a short moment.
12:23You might even mistake them for mosquitoes.
12:27Those are your white blood cells.
12:29They're moving inside your capillaries running through the front part of the retina in your eyes.
12:33The funny thing is, most people don't notice the dots until someone asks them to pay attention.
12:41The Ring of Fire is not only the name of a popular song, it's also a horseshoe-shaped area in
12:47the Pacific Ocean.
12:48It's about 25,000 miles long and contains around 450 volcanoes.
12:55It's the most seismically active place on Earth.
12:59Over 75% of all active and sleeping volcanoes in the world are located in the Ring of Fire.
13:06No wonder around 90% of all earthquakes happen in this area.
13:12Oh, and by the way, the deepest trench on the planet is also located there.
13:16The Mariana Trench is one of the most famous features of the Ring of Fire.
13:20It's deepest point, the Challenger Deep, lies 36,070 feet below sea level.
13:29Funny fact, before color television appeared in the 1950s, 75% of people claimed they saw black and white dreams.
13:38But these days, the same study has found out that only 12% of people still dream in black and
13:44white.
13:46Scientists think they've found an explanation for this.
13:49It turns out that those who grew up watching black and white television more often have monochrome dreams.
13:56Why so serious?
13:58In the 1800s, having a photograph of yourself was a big luxury.
14:03Smiling in pictures was considered childish and even impolite.
14:08That and, well, a lack of proper dental hygiene.
14:12Photographers told these people posing for their pictures to say prunes instead of cheese.
14:17This word kept people's mouths shut.
14:19That's why all our ancestors look as if they've eaten something sour before posing for a photo.
14:27When going somewhere by city bus, you don't have to wear a seatbelt.
14:31You might have thought that this goes against every traffic rule you can imagine, but that's not exactly the case.
14:38There are several reasons why buses have no seatbelts.
14:41In case of an emergency, passengers need to be able to get off as fast as possible.
14:46If they have their seatbelts on, they'll waste precious time unbuckling them.
14:52Secondly, a bus is a heavy vehicle.
14:54In case of a crash, it stops more slowly than a car.
14:58So, even though the passengers will feel the impact, they won't get seriously hurt.
15:03That's also the reason why people are allowed to remain standing on a moving bus.
15:10Imagine you're on a date and have accidentally, or not, ordered a garlic pizza.
15:14You check your pockets and, oh no, you haven't brought your breath mints with you.
15:20No worries!
15:21This little trick can help you get out of trouble.
15:23All you need to do is order a cucumber salad or anything with celery.
15:28These fibrous vegetables can wash away odor-causing bacteria and help you get rid of bad breath.
15:34Try holding a slice of cucumber between your tongue and the roof of your mouth.
15:38It'll be the same or even better than a breath mint.
15:42Here's a riddle for you.
15:44A pointy mustache, melting clocks, and the Chupa Chups logo.
15:47What do these things have in common?
15:50It turns out, Salvador Dali was the very person who designed the logo of Chupa Chups.
15:56The surrealist artist also suggested that the logo should be placed on top of the lollipop
16:01so people could see it at all times.
16:05Lady Liberty, when it first arrived in New York, wasn't green.
16:09It was the same color as a penny.
16:11Copper, that is.
16:12It turned green over time due to the process known as oxidation.
16:16But it still looks amazing, right?
16:19The difference between the American and European chocolate does exist.
16:24But why don't they taste the same, you might ask?
16:26The answer is simple.
16:28Different regulations.
16:30European chocolate has to contain at least 14% of dry milk solids,
16:35while the minimum amount in the U.S. is 12%.
16:38This means European chocolate is kind of creamier.
16:42It's also more chocolatey since it contains more cocoa.
16:47Experts had been experimenting with the potato chip shape
16:50until they finally got the ideal formula.
16:53That curvy shape we associate with chips has a scientific name.
16:57This shape helps prevent big problems.
17:00If chips were shaped in a different way,
17:02they would immediately break into pieces once put into a bag.
17:05But the curvy shape helps them remain in one piece.
17:09You might have noticed a similar approach in architecture
17:12when domes and arches strengthen the structure of a building.
17:16Next time you follow a recipe
17:17where you need to separate egg yolks from whites, try this.
17:21Peel a clove of garlic and rub your fingers with it.
17:24Carefully break an egg into a bowl.
17:27With your garlicky fingers, pick up the yolk.
17:30And voila, you can now marvel
17:32at how perfectly it separates from the egg white.
17:36If it's egg peeling time, there are two easy ways to do it.
17:40When cooking eggs, add a teaspoon of baking soda to the boiling water.
17:43This will make peeling eggs much easier.
17:46You can also place them under cold running water as soon as they're ready.
17:50The eggshells will come off much easier
17:53and you won't burn your hands while peeling the eggs.
17:57The sides of roads have sleeper lines for a very important reason.
18:01Their main function is to alert those drivers who doze off behind the wheel.
18:05When a car starts steering off the road,
18:07the tires go over the lines and the sound wakes the driver up.
18:13Those price tags and labels that come glued to your Tupperware
18:16are easier to remove than you might think.
18:18No need to waste hot water and soap trying to remove them.
18:22Take a hairdryer instead.
18:24Blow some hot air directly onto the tag for a minute or so.
18:28There you go.
18:29The label comes off at once.
18:32White household appliances might get yellow with time.
18:35To make them white again, use this simple trick.
18:38Apply bleaching cream to the surface of an item.
18:41Wrap it in plastic and let it stay this way overnight.
18:44The next morning, check it out.
18:46It'll be as white as when you first bought it.
18:49When you buy a pack of cans, opening it might turn into a problem.
18:54You probably tear a hole in the plastic and try to squeeze a can out of there.
18:58But the bottom of cans was actually designed to make this part much easier.
19:03Grab a can and rub it over the top of another can from the pack.
19:07A circle the exact same size of the can will be cut out.
19:10This way, you can easily remove the new can from the pack without destroying the entire thing.
19:17Now to the art of lime squeezing.
19:20When you pick limes at the grocery store, you never know how juicy they are.
19:24And often, when you bring them home and squeeze them, almost no juice comes out.
19:29Try heating these citruses in a microwave for 30 seconds before cutting them open.
19:33You'll see that the juice will come out much easier.
19:37But be careful, they're going to be hot and you don't want to burn your hands.
19:42If you're hanging out with your friends and feel like listening to some music but don't have a loudspeaker, there's
19:48no need to worry.
19:49Place your phone in a cup or bowl.
19:51The sound will get louder instantly.
19:55If you don't have a hanger at hand but still need to hang your shirt, this trick is for you.
20:00Most dress shirts have a tiny loop on the back between the shoulders and you can use it to hang
20:05your shirt.
20:06How about the worst case scenario?
20:08Your phone is running out of battery and you're running late.
20:11Try this simple trick.
20:13Switch on airplane mode.
20:15Your phone will charge to 100% in no time.
20:24You can run the sticky part of a post-it note along your laptop's keyboard.
20:28This will help remove tiny bits of food and dust that get stuck in between the keys.
20:34Avoid putting really hot food into plastic containers.
20:37Hot plastic releases all kinds of toxic chemicals and we don't want our food to absorb that nasty stuff, right?
20:45What can be better than a bubble bath in the evening?
20:48But the bubbles are not only pretty and smell nice.
20:51They also keep the water temperature hot for longer.
20:54This way, you can enjoy a long hot bath without getting cold too quickly.
20:59You got home craving a peanut butter and jelly sandwich, but your peanut butter now has two layers and the
21:04oil is at the top.
21:06To avoid getting disappointed, next time, store a peanut butter jar turned upside down.
21:15Your screwdriver and wrench can work together to remove that stubborn screw.
21:20Grab your screwdriver's handle with the wrench and use it to apply more force.
21:24This method will also help you reach more difficult areas.
21:29There is a reason why your coffee stirrer looks like a straw.
21:32It has holes in it because it reduces the amount of plastic manufacturers have to use.
21:37Plus, they prevent the stirrer from floating.
21:40The holes in the stirrer get filled with coffee, which in turn makes it heavier.
21:47And speaking of coffee, you should never buy the product that is more than 18 months old.
21:51Make sure to look at the best before date when buying it.
21:56If you've ever had trouble with those classic salt and pepper shakers, the ones you may see in diners, I've
22:02got a trick for you.
22:03Instead of shaking your entire arm to try and get some salt out of the container, try rubbing the bottom
22:08of one container with the bottom of the other.
22:11Grab the salt and hold it so that the bottom of the container faces downward.
22:15Now, while holding the pepper shaker upright, rub the two bottom parts together, creating circular friction between them.
22:22After this, the salt will spill effortlessly.
22:26After a long day of hiking, your shoes might smell funny.
22:29Well, I've got good news for you.
22:31Put dry teabags inside your shoes and keep them in a dry place for a while.
22:35The teabags will absorb bad smells and make your shoes dry.
22:40If you've torn your flip-flop while taking a walk, there's a way to save the day.
22:44But only if you have a bread clip with you.
22:47First, push the strap back into its hole.
22:49Then attach the bread clip to the bottom of the flip-flop strap.
22:53Here you go!
22:55Your body needs a daily amount of vitamin C to boost your immune system.
22:59But oranges are a tricky fruit to peel.
23:02To avoid getting sprayed all over your face, start by cutting off both the top and the bottom parts of
23:07the orange.
23:08Then, cut the peel vertically.
23:10Hook your fingers under the opposite sides of the cut and open your orange.
23:16If it's difficult for you to figure out how much detergent you need to wash your clothes, here's a tip
23:21for you.
23:22Usually, detergent caps have markings that indicate the exact amount of liquid you should use per wash.
23:28It helps your detergent last longer.
23:32Permanent markers are not as permanent as you might believe they are.
23:36I can prove it.
23:37Let's say you used a permanent marker, thinking it was a regular one, to draw something on a whiteboard.
23:42Good news for you!
23:43You don't need to throw the board away yet.
23:45There's a way to save it.
23:47Get a regular marker and use it to draw over the lines left by the permanent one.
23:52Let it sit for a while so that both markers blend in together.
23:55The thing is, the ink of the regular marker contains a solvent that dissolves the pigment the permanent marker contains.
