00:00:00Road and construction workers are usually dressed in orange because the bright orange hue is visible even in bad weather.

00:00:07It's the most effective color to attract attention and alert people.

00:00:10No wonder lots of safety jackets and traffic cones are orange as well.

00:00:14The stop sign has an eight-sided shape to help drivers recognize it easily, even if they see it from

00:00:20the back.

00:00:20And when the signs weren't reflective yet, the octagon shape prevented drivers from confusing the stop sign with any other

00:00:27at night.

00:00:28The rumble strips on the side of the road are placed there to alert drivers who doze off behind the

00:00:33wheel.

00:00:34When their tires move over these strips, the noise and vibration work like an alarm clock.

00:00:39There are magnetic locks on fuel hoses at gas stations.

00:00:43They come in handy if someone drives away with the gas nozzle still attached to their car.

00:00:48In this case, the lock detaches the hose automatically.

00:00:51Oh, that's embarrassing.

00:00:53Gasoline looks like a rainbow in a puddle because it can't mix with water.

00:00:56It forms a thin membrane over it.

00:00:59When light reflects from it and the water at the same time, you've got a rainbow.

00:01:05A triple handle on a jerry can is there to make it easier for two people to carry it and

00:01:10distribute fuel evenly.

00:01:12Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.

00:01:17The air passage will prevent it from pouring out, so no more fuel waste.

00:01:22Most gas cans have two holes with caps, a bigger and a smaller one.

00:01:27You're supposed to uncap the smaller hole before pouring gas inside the bigger one.

00:01:31It'll prevent the liquid from glugging and spilling all over your clothes and the ground.

00:01:37Another little thingy we often neglect is a point on an ointment cap.

00:01:40Most tubes are usually sealed with a plastic film or a foil, and opening it with your fingernails isn't the

00:01:46best idea.

00:01:47A point easily opens even the most safely sealed tube.

00:01:52You can use most screwdrivers together with a wrench to create more torque.

00:01:57Just place the wrench over the handle of the screwdriver.

00:02:00This way, you'll need to apply a lot less force than before.

00:02:04You'll also be able to get to hard-to-reach areas more easily.

00:02:08They install cameras in shops, banks, and hospitals to monitor everything.

00:02:13If something happens, you can call the police or rescuers.

00:02:17The camera really helps to solve a lot of problems.

00:02:19Why are there no cameras on planes?

00:02:23The crew keep order on the plane, but they won't be able to do anything if something serious happens.

00:02:28Besides, there's nowhere to run on the plane.

00:02:31During the flight, the cameras are useless, and after the flight, the words of the passengers work ideally instead of

00:02:38cameras.

00:02:38So, if cameras do no good, then why spend money on them?

00:02:43Water is great at cleaning stuff because it has triangular molecules.

00:02:47They're made of one oxygen and two hydrogen atoms.

00:02:50Um, H2O?

00:02:51Such molecules have slightly different charges on their opposite sides, pretty much like magnets.

00:02:57That's why water easily sticks to other molecules, including those that make up dirt.

00:03:02Lots of private houses have triangular-shaped roofs because this allows rain, snow, and fallen leaves to slide off the

00:03:08slope.

00:03:09If all this stuff piled up on top of your house, one day, your roof would collapse.

00:03:15When a storm is coming, clouds seem to turn dark, but it's just an illusion.

00:03:20Thin clouds on a sunny day let the light through easily.

00:03:23They also scatter all the colors of the light spectrum.

00:03:26This makes us perceive the clouds as white, but the thicker the clouds are and the more water droplets they

00:03:32contain,

00:03:32the less light they let through and the darker they look.

00:03:36A good doorknob is the one made of brass, bronze, or some copper alloys.

00:03:42Diamonds have an anti-germ effect.

00:03:45Bacteria spread way slower on them.

00:03:47They also get rid of germs pretty fast, within a couple of hours.

00:03:51Nope, it doesn't mean you don't have to wash your hands.

00:03:55Diamonds have such symmetrical shape to show you their brilliance.

00:03:58Initially, the gems aren't so beautiful.

00:04:01They go through several stages of cutting and then become pieces of elegance.

00:04:06Most of these stones have a round shape with slightly pointed corners.

00:04:10Diamonds shine the brightest in this shape.

00:04:14Why are there two holes in the socket?

00:04:16The left hole is neutral, the right hole is not, and the gap underneath is ground.

00:04:22Electricity needs to flow through the chain.

00:04:25The current flows from the hot slot, passes through your phone charger, for example, and then goes through the neutral

00:04:31hole.

00:04:32Ever wondered what that small pocket on your jeans is for?

00:04:35People used to wear watches on chains.

00:04:37That small pocket was meant for it.

00:04:40Now, almost no one wears such a watch, but the pocket remains.

00:04:44You can still keep something small in there, like a ring.

00:04:47In London, there are some poles that look like street lamps, but there are no bulbs.

00:04:52Well, their official name is stink pipes, and they're a thing of the past now, but they used to come

00:04:58in handy back in the 19th century.

00:05:00These hollow poles would vent away the air and explosive gases with bad smells to prevent, shall we say, unwanted

00:05:07consequences.

00:05:09Most kitchen shears have metal, plier-like teeth in the middle.

00:05:13Between the handle grips, they can help you crack nuts, crab shells, and other tough products.

00:05:18You can also open jars and bottles or remove herb stems with their help.

00:05:23Leather often looks dull to the eye because it's covered with itsy-bitsy scratches and scrapes.

00:05:29They scatter the light that hits the material.

00:05:31When you coat your shoes in a layer of wax, you fill these tiny crevices.

00:05:35The surface becomes smoother, and the rays of light bounce off it more evenly.

00:05:40That's why the leather looks shiny.

00:05:43Highlighters are filled with a special semi-transparent fluorescent ink that can glow in dim light.

00:05:50Yellow and light green hues are the most popular because they don't prevent you from seeing the text after black

00:05:56-and-white photocopying.

00:05:58Photocopiers perceive yellow and light green marks as very pale and don't print them.

00:06:02They make magnets shaped as a horseshoe because this increases the magnetic force.

00:06:08Colors matter too.

00:06:09The blue part indicates the south pole.

00:06:12The red part, the north pole.

00:06:14The two poles work simultaneously and increase the attraction force.

00:06:18The dime-sized holes in elevator doors is actually a keyhole.

00:06:23If the doors get stuck, an operator can open them manually thanks to this hole.

00:06:28They'll just insert a special key.

00:06:30The tiny hole in the airplane window is there to balance air pressure.

00:06:35The window has three layers.

00:06:37The outer pane is extremely sturdy.

00:06:40It can withstand air pressure differences during takeoff and landing.

00:06:44The inner pane, which is the closest to you, is made of cheaper materials.

00:06:48It prevents potential damage to the window.

00:06:50The hole itself is in the middle pane.

00:06:53It not only balances the pressure, but also prevents the window from fogging.

00:06:59Escalator brushes are there for your safety.

00:07:01They don't allow you to come too close to the edge of the escalator.

00:07:04This way, your clothes won't end up between the steps.

00:07:08You see the sun as yellow or orange.

00:07:11Because the atmosphere of our planet scatters such colors as blue, green, and violet.

00:07:16This is also why the sun looks warmer at sunrise and sunset.

00:07:21Go shopping for some oranges and I'm sure you'll get them in a red mesh bag.

00:07:25You'll rarely see them lying around without one of those.

00:07:28It's pure marketing, and that color isn't a random choice.

00:07:31When packed in a red mesh bag, oranges appear more orange, fresher, and more appealing to you.

00:07:38So, you're more likely to buy them, right?

00:07:41Lemons are usually sold in green mesh bags for a similar reason.

00:07:45If you pack them in red, they'll appear more orange.

00:07:47Green goes better with yellow, and makes those lemons stand out.

00:07:52Mattress manufacturers make a limited number of different mattresses.

00:07:56And the only way to make them look different is to come up with a fancy stitching pattern.

00:08:01Two mattresses of two different companies might be the exact same quality, but cost differently.

00:08:06Most people will never know it, and will decide that different patterns mean something in terms of quality.

00:08:12So, when shopping, don't mind the pattern at all.

00:08:16Almost all hotels have white bedsheets.

00:08:18They choose this color specifically to show how high their standards of cleanliness are.

00:08:23The whiter and brighter the sheets are, the more luxurious the hotel seems.

00:08:27It's much easier to see dirt and stains on white linen.

00:08:31It's like proof that you've checked into a clean room.

00:08:34There are some inventions that make us say,

00:08:37Dude, why didn't I come up with this?

00:08:39And then you have the next question.

00:08:41Why don't we have it in my hometown yet?

00:08:44I'm talking about things like splash-proof toilets, liquid trees, and skyscrapers with slides.

00:08:52Yep, they're all pretty real, and you're about to fall in love with them.

00:08:57Have you ever used a public bathroom in the summer in your shorts and sandals and got splashed?

00:09:04It happens to the best of us, so no worries.

00:09:06If only there was some solution to this problem.

00:09:09Perhaps a urinal with a small hole so no liquid goes where it shouldn't.

00:09:14Looks pretty yucky and painful to me.

00:09:17An assistant professor at the University of Waterloo,

00:09:21Zhao Penn and his colleagues came up with a way better solution for this sensitive issue.

00:09:27Their designs were inspired by physics and dogs.

00:09:30When a stream of liquid moves on a solid surface at a shallow angle,

00:09:35the splash is reduced, and the smaller the angle, the fewer splashes you'll see.

00:09:39You can even minimize them to a zero.

00:09:42And when dogs do their business, they lift their hind legs and do it on the vertical surface of a

00:09:47tree or a wall.

00:09:48I don't know if they actually care about it, but this does reduce the splash.

00:09:53Good job, Pluto!

00:09:55The team invented several models and presented them at the American Physical Society conference,

00:10:00and it was a hit.

00:10:02The inventors say that all of the models are no splash,

00:10:05but their favorites are the slice of apple and the one that looks like a tall and slender jay with

00:10:11a narrow and long opening.

00:10:13The new urinals aren't just super cool, but also more sustainable.

00:10:18You won't have to wash the floor with water, chemicals, and human energy after every use, which is a win

00:10:24-win.

00:10:26Here's another innovative public toilet idea for you, this time from Japan.

00:10:31They have completely transparent walls, which means, yes, you can see everything that's going on inside,

00:10:38from the toilet itself to the hand wash sink.

00:10:41It sounds pretty creepy, but the idea was actually to create a safe restroom in the park.

00:10:47Visitors can see if there's someone hiding inside before entering,

00:10:50and also check if the toilet is clean before entering.

00:10:54When you go inside and lock the door, the walls change color to opaque, and no one will be able

00:11:00to see you.

00:11:01They used glass covered with PD-LC film to make the walls,

00:11:05which allowed them to go from being transparent to safely in tents using electricity.

00:11:11Alright, now you've nearly convinced me to try one of those magical toilets.

00:11:15Oh, and they also double as excellent lanterns in the dark, shining bright in different colors.

00:11:21Bring a couple to my local park, I don't mind.

00:11:24Take a deep breath.

00:11:26If you don't like what you're breathing in, do something about it.

00:11:29That must have been exactly what the smart guys at the University of Belgrade, Serbia thought,

00:11:34and invented the liquid tree.

00:11:37The liquid tree, not the pun and laugh a bit,

00:11:40consists of a glass tank filled with over 150 gallons of water,

00:11:45some microalgae, and a solar panel, which provides electricity to a small pump.

00:11:51The microalgae need heating, so just in case there's no sun and the temperatures drop,

00:11:55the photobioreactor is also connected to the city grid.

00:12:00Microalgae work hard to do some photosynthesis magic and convert water and CO2 into oxygen,

00:12:06and then it goes into the atmosphere.

00:12:09The liquid tree also comes with a bench to sit on and enjoy its work.

00:12:13The liquid tree needs more work than a regular tree in the park.

00:12:17They need to replace the water and microalgae almost completely every month and a half.

00:12:23And they also need to take out the biomass that is the byproduct of the process,

00:12:28and let's admit, nothing can replace those blooming babes in spring.

00:12:32If you ever find yourself casually wandering in the forests of Estonia,

00:12:36don't freak out if you see some giant megaphones.

00:12:39These wooden, acoustic giants were set three hours away from the country's capital by interior architecture students.

00:12:47That's way cooler than the hamster roller coaster I once built for a science fair, I have to admit.

00:12:53More than half of Estonia is covered by woods, and they're pretty proud of this natural wealth.

00:12:58So it's not the first art project of this kind,

00:13:01and there was a winding, elevated pathway and a faceted woodland cabin.

00:13:06The idea of the megaphones is to crank up the natural sounds of a forest and also to serve as

00:13:13a rest spot for hikers.

00:13:15These wooden beauties are large enough to host several people.

00:13:19And hey, if you walk this far into the woodland, you'll be thankful for this.

00:13:24The students were given a task to invent some concepts of a forest library.

00:13:29They built the megaphones off-site and brought them to their permanent spots.

00:13:33They're set in such a way that sounds from three directions meet in the center

00:13:38and create a cool, natural surround sound effect.

00:13:41Have you ever helped your friends move into a new apartment in a building without an elevator?

00:13:47Then you're gonna love this one.

00:13:49Houses in Amsterdam have hooks on top.

00:13:52This is a medieval invention for pulling stuff up the houses.

00:13:55The simple tech consisting of a wheel and a rope still functions now, centuries later.

00:14:00Why not just use the stairs?

00:14:02Well, if you get inside one of those narrow Amsterdam buildings,

00:14:07you'll see there's hardly enough room to comfortably ascend,

00:14:10and you can forget about even trying to pull a table on top.

00:14:14Back in the medieval ages, pretty much like now,

00:14:18only rich people could afford housing around the canals in the best parts of the city.

00:14:22Those people were mostly traders and used the canals for their business.

00:14:27They stored goods in the same houses they lived in,

00:14:30and with regular floods, they had to find a way to keep the goods dry.

00:14:34And that's why they needed to invent something to lift furniture,

00:14:38goods, boxes, instruments, and food on the upper floors,

00:14:43and pull it in through fully open, wide windows.

00:14:46The lifting tech is one of the reasons the houses in Amsterdam are leaning forward.

00:14:51This position helped keep both the lifted stuff and the walls and windows safe during transportation.

00:14:58They didn't have to touch each other.

00:15:01The gables also assisted in the process and had to be made firm to withstand all the heavy weight.

00:15:07And in case you're wondering what gables are,

00:15:10they're sections of wall between the edges of a dual-pitched roof, typical for Amsterdam.

00:15:17Folks who live or work in skyscrapers have the opposite problem.

00:15:21Getting out of the building can take a while as you wait in line for the elevator.

00:15:25A slide going from the top of a skyscraper could be a solution.

00:15:29In 2016, they added one outside of the U.S. Bank Tower in Los Angeles at the height of 1

00:15:36,000 feet.

00:15:37The see-through slide, made of glass just one inch thick,

00:15:40was built to withstand hurricane-force winds and earthquakes.

00:15:43It was built to bring tourists to the building, though not for the convenience of office workers.

00:15:49And then they decided it wasn't such a great idea,

00:15:53so the slide was removed as part of the reconstruction of the building.

00:15:57A Hong Kong photographer and editor who became famous online went even wilder with his imagination

00:16:04and designed a double-decker bus with a slide.

00:16:07It's not his only futuristic photography masterpiece,

00:16:11as he likes to play with perspective and proportions.

00:16:14I can totally see myself sliding away when someone asks me to pay for the ride.

00:16:20If you look at it on the street, you'll think a fire hydrant is about 3 feet in height.

00:16:25But the actual size of the device used to provide water supply to firefighters all over the world is twice

00:16:31as large.

00:16:31That is, if you count the rest of the hydrant, which is hiding underground.

00:16:35They're mostly red, and it's not just a matter of urban design.

00:16:38First of all, they need to be of bright, easily noticeable colors,

00:16:42so firefighters can spot them fast when they need to.

00:16:45The choice of color depends on how much water the hydrant can hold.

00:16:49It can sometimes vary depending on the location, but here's the breakdown.

00:16:52A red fire hydrant can splash 500 gallons of water per minute,

00:16:57while an orange one at least 1,000 gallons.

00:17:02Green ones mostly process 1,500 gallons of water per minute,

00:17:05and the most plentiful ones colored blue can generally contain over 1,500 gallons.

00:17:11Hey bowling fans, isn't it super annoying when your bowling ball gets cracked?

00:17:15Turns out that most of them get damaged because of incorrect storage or spikes in temperature.

00:17:22Now come on and face it, since it's already cracked a bit,

00:17:25aren't you curious what's actually inside the bowling ball?

00:17:27Because I sure am.

00:17:28Let's have a look.

00:17:30They mostly make the inner core of the ball of powdered metal oxides,

00:17:34like calcium or iron oxide.

00:17:36They mix them with some resin and catalyst to harden the whole mixture.

00:17:40So that light bulb shape you now see inside of the ball is actually its heaviest part.

00:17:45It also influences how your bowling ball rotates when going down the lane.

00:17:49The same goes with spray paint cans.

00:17:52When you shake it, it makes a weird noise.

00:17:54But what is that thing in there?

00:17:56It's called a pee, and it's meant to hold the paint mixture in place and maintain its shape.

00:18:01They generally make it out of plastic, metal, or ceramic.

00:18:04It basically acts as a whisk to make sure your paint is well mixed together

00:18:08before you apply it to your surface of choice.

00:18:11Ever wondered how soda bottles keep that refreshing fizz for that long?

00:18:16Well, they have a little plastic ring fastened to the lid.

00:18:19They place it there to keep the gas from escaping and making the soda go flat,

00:18:23even if you shake it around in your bag the whole day.

00:18:28Speaking of things we use on a hot summer's day,

00:18:30wait, wait, don't put your baseball cap on just yet.

00:18:33Take a look at it for a minute, and you'll notice there's a small button on the very top.

00:18:37Is it functional, or is it just there for the sake of design?

00:18:40Way back when people started using fabrics to cover their heads,

00:18:44some say the button was actually functional.

00:18:46Since it's on top of the cap where the fabric panels come together,

00:18:50the top button helps keep the cap crown in one single piece.

00:18:54Now, with recent advances in fabric and pattern design,

00:18:57the button is more of an aesthetic feature.

00:18:59It's used to cover up the joint point of the fabric panels.

00:19:02Your cap might not have a button at all,

00:19:04but don't you think a cap actually looks better with one?

00:19:08Cotton pads have two sides,

00:19:10and if you take the time to look at them carefully,

00:19:12they're actually different in texture.

00:19:14Just in case you've ever wondered why,

00:19:16the textured side is for applying makeup,

00:19:19and the even side is for removing it.

00:19:23Bookworms, this one is for you.

00:19:24Dust jackets that come with a lot of hardcover books

00:19:27are not just meant to make your book look pretty,

00:19:29they also double as a bookmark.

00:19:31Just fold the pages you've already read underneath the inside of the jacket,

00:19:35and voila!

00:19:37Next time you reach out for your favorite shirt,

00:19:39take a look at the top buttonhole.

00:19:41It should be stitched horizontally,

00:19:43and all the other ones are vertical.

00:19:45Turns out that the dress shirt was designed this way,

00:19:48since the first and the last buttons

00:19:50were the first ones to unbutton throughout the day.

00:19:52They then changed the direction of the buttonhole

00:19:55to ensure the shirt would stay nice and fitted

00:19:57before you're ready to take it off.

00:20:00These days we have so many variations of this awesome dessert,

00:20:04that it's hard to imagine we've ever lived without it.

00:20:06You can find different types of cookie dough ice cream

00:20:08or even chocolate chip cookie cake basically everywhere,

00:20:11but the famous cookie wasn't actually invented until 1930.

00:20:16The story goes that a woman named Ruth Graves Wakefield

00:20:19was preparing some chocolate cookies

00:20:21as she was waiting for some guests to arrive.

00:20:23She soon figured out she was out of Baker's chocolate,

00:20:26a crucial ingredient for the classic cookies.

00:20:28To fix things up,

00:20:30she chopped up a block of semi-sweet chocolate,

00:20:32thinking it would eventually spread out evenly

00:20:34throughout the batter, given the heat of the oven.

00:20:36Things didn't necessarily go as planned.

00:20:39But hey, it's great they didn't

00:20:40because this is how she invented this modern dessert

00:20:42we now can't get enough of.

00:20:46And speaking of popular snacks,

00:20:48the potato chip is even younger than the chocolate chip cookie.

00:20:51Well, at least historically.

00:20:53There are many stories trying to explain how it was invented.

00:20:57One of them goes like this.

00:20:58A chef named George Crumb, based in New York,

00:21:01put the chips together in 1953.

00:21:04He decided to try a different cooking solution

00:21:06when one of his customers didn't have nice things to say

00:21:09about his French fries.

00:21:11He said they were too thick and kind of mushy.

00:21:14Then, Crumb came up with potatoes that were thinly sliced

00:21:17and fried until brown.

00:21:19People absolutely loved the dish,

00:21:21and they welcomed the first ever batch of chips

00:21:24with open arms.

00:21:26Ice cream, anyone?

00:21:27If the story is true,

00:21:29back in 1904 at the St. Louis World's Fair,

00:21:32one ice cream shop owner ran out of cups to serve his dish.

00:21:35So, he fashioned a waffle into the shape of a cone,

00:21:38and the rest was history.

00:21:41Okay, I'll admit it,

00:21:42chewing gum-like treats have been around since the ancient Greeks.

00:21:45So this one isn't particularly a revolutionary discovery,

00:21:49but the actual gum we buy today

00:21:51wasn't there until the late 1800s.

00:21:53An American inventor named Thomas Adams

00:21:56wanted to mix together different chemicals to create rubber.

00:21:59He tried and failed for that matter

00:22:02to play with Chickle for his experiment,

00:22:04but ended up fashioning this neat treat.

00:22:06They still use Chickle to this day

00:22:08to produce most chewing gums.

00:22:10Back in the 1800s,

00:22:12there lived a man named Jean-Baptiste Jolie,

00:22:14who worked in the fabric industry as a textile maker.

00:22:17How he came up with this next invention

00:22:19that we use a lot these days

00:22:21has less to do with him

00:22:22and more to do with his maid.

00:22:24The story goes

00:22:25that the woman accidentally knocked a kerosene lamp over

00:22:29onto a tablecloth.

00:22:30Instead of getting upset over the damaged fabric,

00:22:33Jolie noticed that the substance

00:22:35actually made the material cleaner.

00:22:37Figured it out yet?

00:22:38Yep, that's how the idea

00:22:40for the very first dry cleaner popped up.

00:22:42A very neat accident,

00:22:43if I do say so myself.

00:22:46Now this one I loved.

00:22:48Did you know matchsticks

00:22:49were initially called friction lights?

00:22:51Or at least that's how their inventor,

00:22:53a chemist named John Walker,

00:22:55called them back in 1826.

00:22:58He scraped a stick coated in chemicals

00:23:00across his hearth,

00:23:01totally by accident one day,

00:23:03and realized that they ignited

00:23:04and created a spark.

00:23:06Initially made out of cardboard,

00:23:08they were then made

00:23:09using wooden splints and sandpaper.

00:23:13Back in the 1940s,

00:23:15a man named Harry Coover

00:23:16stumbled upon a chemical formulation

00:23:18that seemed to stick

00:23:19to everything it touched.

00:23:21The scientific community at the time

00:23:23didn't look much into it

00:23:24as the formula didn't seem

00:23:25to have many applications back then.

00:23:28It wasn't until 1951

00:23:30that he looked a bit more into the formula

00:23:32and decided to repurpose it,

00:23:34along with a fellow

00:23:35Eastman Kodak researcher

00:23:36named Fred Joyner.

00:23:37They gave it a proper full name.

00:23:40But you must know it

00:23:41by the shorter version,

00:23:43super glue.

00:23:45It also has many uses

00:23:47in security these days

00:23:48that it's hard to believe

00:23:49that we didn't come up

00:23:50with this one on purpose.

00:23:51Back in 1903,

00:23:53a scientist named Edward Benedictus

00:23:55knocked over a flask by accident.

00:23:58He looked down

00:23:59and was amazed to see

00:24:00that the glassware

00:24:01had just slightly cracked

00:24:02but maintained its shape.

00:24:04He was expecting it to break

00:24:05into a million tiny pieces.

00:24:07Curious about this hidden feature,

00:24:09he looked into it

00:24:10and figured out

00:24:11what was keeping the glass together

00:24:12was a substance coating

00:24:14the inside of the glass.

00:24:15Ta-da!

00:24:16That's how humanity

00:24:17came up with safety glass.

00:24:22So get this,

00:24:23an extra hole

00:24:24at the upper part of the sink

00:24:25has multiple hidden functions.

00:24:27First,

00:24:28in case someone forgets

00:24:29to close the tap,

00:24:30the water won't overflow

00:24:31and the bathroom won't get flooded.

00:24:33Second,

00:24:34thanks to that hole,

00:24:35the water drains faster

00:24:36and it gives an escape

00:24:37for the air,

00:24:37helping the water flow down.

00:24:41Those two holes

00:24:42on a side of any Converse shoe

00:24:43are not only

00:24:44to let the stinky air out.

00:24:46Sure,

00:24:46breathability is important

00:24:47for any athlete.

00:24:48The second reason

00:24:49is that athletes

00:24:50lace through those holes

00:24:51to get a better grip.

00:24:55Donuts have a hole

00:24:56in the middle

00:24:57and it doesn't stand

00:24:57for O in donut.

00:24:59It's not designed

00:25:00for an easier grip either,

00:25:02though it can be

00:25:02quite convenient.

00:25:03It's actually made this way

00:25:04for mass baking

00:25:05so that they can cook

00:25:06all the way through evenly.

00:25:10Baby carrots are tiny

00:25:11and,

00:25:12unlike regular carrots,

00:25:13wet.

00:25:14Baby carrots

00:25:15aren't some special

00:25:16sort of carrots.

00:25:16They're actually made

00:25:17of regular carrots

00:25:18by cutting off the skin

00:25:19and outer layers

00:25:20and then polishing them

00:25:22to look that pretty.

00:25:23The problem

00:25:24is that they can't

00:25:25retain moisture.

00:25:26A regular carrot

00:25:27retains some water inside

00:25:28because of the layers

00:25:29that locks it in.

00:25:30Once they're chopped out,

00:25:32baby carrots

00:25:32can dry out easily,

00:25:33so they usually sell them

00:25:35in bags

00:25:35with some water inside.

00:25:38Toy stores are filled

00:25:39with Beanie Baby

00:25:40plush toys

00:25:41and a detail

00:25:41that is even more iconic

00:25:43than their huge eyes

00:25:44is their tags

00:25:45saying T.Y.

00:25:47That's a small

00:25:47manufacturing company

00:25:48not so many people

00:25:49have heard of.

00:25:50Beanie Babies

00:25:51appeared in 1993

00:25:52and they went

00:25:53insanely popular.

00:25:55T.Y.

00:25:56is the name

00:25:56of the company

00:25:56but it's not

00:25:57an abbreviation.

00:25:58It's the actual name

00:25:59of the company's founder,

00:26:01H. Ty Warner.

00:26:04Most metallic zippers

00:26:05have a hidden lock

00:26:06inside them

00:26:07to save you

00:26:07from awkward situations

00:26:08such as an undone fly.

00:26:11Oh boy.

00:26:12Don't leave the zipper handle

00:26:13in an upward position.

00:26:15When you pull it downwards,

00:26:16it automatically locks.

00:26:17It's all thanks

00:26:18to those tiny grooves

00:26:19hidden underneath the handle.

00:26:23Almost any public toilet

00:26:25has a large gap

00:26:26between the floor

00:26:27and the door.

00:26:27The reason for such

00:26:29a zero privacy thing

00:26:30is to actually minimize

00:26:31the level of privacy

00:26:32and comfort

00:26:33so that people

00:26:34wouldn't stay there long

00:26:35and there'd be no lines.

00:26:36It's also easier to clean

00:26:38and safer

00:26:39if some emergency occurs.

00:26:43Headrests in a car

00:26:44are about comfort

00:26:45and detachable headrests

00:26:47are about safety.

00:26:48If you pull the headrest

00:26:49out of a seat,

00:26:50you'll see two bars

00:26:51which are quite sturdy.

00:26:53If you ever get locked

00:26:54or trapped in a car,

00:26:55you can get out of there

00:26:57smashing the window

00:26:57with these bars.

00:27:02Many cups and mugs

00:27:03have little grooves

00:27:04on the bottom on purpose.

00:27:05They're designed

00:27:06for dishwashing machines.

00:27:07The grooves

00:27:08let the water flow

00:27:09and not spill over your feet

00:27:11when you take the cup out.

00:27:12Also,

00:27:13those grooves

00:27:14let the air flow

00:27:15so the cup doesn't crack

00:27:16even if the tea is scalding.

00:27:20Almost all measuring tapes

00:27:21have a metal tip

00:27:22with a small slot

00:27:23on the end.

00:27:24You can use this slot

00:27:26to hang the tape on a nail

00:27:27or a screw

00:27:27to make measurements

00:27:28without anyone's help.

00:27:31Sometimes,

00:27:32this tip has a row

00:27:33of sharp points

00:27:33along the edge

00:27:34on one side.

00:27:35That comes in handy

00:27:36when you want to leave a mark

00:27:37without using a pencil.

00:27:40Doorknobs are usually

00:27:41made of brass,

00:27:42bronze,

00:27:43and some other copper alloys

00:27:44for a reason.

00:27:45They have an antibacterial effect,

00:27:47so they stop microbes

00:27:49from spreading.

00:27:50They get rid of a range

00:27:52of harmful germs

00:27:53pretty fast

00:27:53within a couple of hours.

00:27:55But don't forget

00:27:55to wash your hands anyway.

00:27:59Grocery carts

00:28:00have loops

00:28:00for a reason.

00:28:01You don't want to put

00:28:02your jacket in a cart

00:28:03next to potatoes and onions.

00:28:05Hang it on a loop.

00:28:07This little hook-like thing

00:28:08is there to help you

00:28:09better organize

00:28:10the space in your cart.

00:28:11The carts also have

00:28:13a super handy grid.

00:28:14Whenever the cart's full,

00:28:16you just need to lift the grid

00:28:17and attach the shopping basket

00:28:18for extra purchases.

00:28:20Placing it in between

00:28:21the horizontal bar

00:28:22above the wheels

00:28:23and the hooks the grid has.

00:28:27A point in an ointment cap

00:28:29is there for a reason too.

00:28:30Most tubes are usually

00:28:31sealed with foil,

00:28:32and it's better to avoid

00:28:33opening it with fingers

00:28:34unless you're ready

00:28:35to say goodbye to your nails.

00:28:37A point easily opens

00:28:39even the most safely sealed tube.

00:28:43Silica gel can often be found

00:28:45in different things you buy

00:28:46like bags,

00:28:47shoes,

00:28:47and many others.

00:28:48Don't throw it away.

00:28:49It's meant to absorb

00:28:50excess moisture,

00:28:52so anytime your shoes

00:28:53are a bit wet,

00:28:54just throw in a packet

00:28:55with silica gel.

00:28:58People used to co-live

00:28:59with rats,

00:29:00and these guys like

00:29:01gnawing on everything

00:29:02they see in their way,

00:29:04including paper.

00:29:06Still,

00:29:06rats weren't able to chew

00:29:07more than the space

00:29:08left on the margins.

00:29:12That black grate on a microwave

00:29:13isn't just some fancy decoration.

00:29:15It's called a Faraday shield,

00:29:17and it prevents the rays

00:29:19from escaping the microwave.

00:29:20It also speeds up the heating,

00:29:22so you can enjoy

00:29:22yesterday's leftovers

00:29:23faster.

00:29:25It may also block

00:29:26phone signals,

00:29:27so if you're tired

00:29:28of numerous calls,

00:29:29just put the phone

00:29:30into a microwave,

00:29:31but don't turn it on.

00:29:35All Tic Tac containers

00:29:37are designed to dispense

00:29:38one Tic Tac

00:29:39every time you open it.

00:29:40The lid has the same shape

00:29:42as the candy.

00:29:43Turn the container

00:29:43upside down,

00:29:44gently shake it,

00:29:45and open it slowly.

00:29:46You'll notice only one candy

00:29:48stuck between those lid grooves.

00:29:50So if you just open

00:29:51the container

00:29:51and shake it

00:29:52until five or even more candies

00:29:54fall into your mouth,

00:29:55it means you've been eating

00:29:56Tic Tacs wrong

00:29:57all this time.

00:30:02Those little holes

00:30:03in the airplane windows

00:30:04are designed to control

00:30:05the cabin pressure.

00:30:06They also protect

00:30:07the windows

00:30:08from fogging up

00:30:08as the temperatures

00:30:09drop and rise.

00:30:10By the way,

00:30:11the airplane window

00:30:12is round for a reason.

00:30:13This way,

00:30:14pressure is evenly distributed

00:30:15so it doesn't get deformed.

00:30:20Blue bristles

00:30:20on a toothbrush

00:30:21are actually an indicator

00:30:22that it's just about time

00:30:24to change the brush.

00:30:25As the bristles

00:30:26get in contact with water,

00:30:27the blue,

00:30:28or whatever other,

00:30:29pigment fades away.

00:30:30So the more you use it,

00:30:32the duller

00:30:32the color becomes.

00:30:35A triple handle

00:30:36on a jerry can

00:30:37is there to make it easier

00:30:38for two people to carry it

00:30:39and distribute the fuel evenly.

00:30:41Gas cans often have

00:30:42a second hole

00:30:43that actually needs

00:30:44to be uncapped too

00:30:45before you pour the gas.

00:30:46The air passage

00:30:47will prevent it

00:30:48from pouring out,

00:30:49so no more fuel waste.

00:30:52Jeans first appeared

00:30:54in 1873.

00:30:55They were invented

00:30:56by Jacob Davis

00:30:57and Levi Strauss.

00:30:59Davis was a tailor

00:31:00who was producing covers

00:31:01and tents

00:31:02and Strauss

00:31:03was a businessman

00:31:04who,

00:31:05among other things,

00:31:06was selling cloth.

00:31:08The first jeans

00:31:08were made by Davis

00:31:10from denim,

00:31:10the fabric he bought

00:31:12from Levi Strauss and co.

00:31:14Together,

00:31:14they patented the design.

00:31:16Blue was a standard

00:31:17color for denim

00:31:18that was dyed

00:31:19using an indigo dye.

00:31:21The blue color

00:31:22is a tradition

00:31:22that is still often

00:31:23followed today

00:31:24to replicate

00:31:25the original look

00:31:25of a pair of jeans.

00:31:27Jeans also have

00:31:28metal rivets

00:31:29and they've been there

00:31:30from the very beginning.

00:31:31Jacob Davis,

00:31:32the man who made

00:31:33the first pair of jeans,

00:31:34added copper rivets

00:31:35to spots where pants

00:31:36were more likely to rip,

00:31:38flies and pockets

00:31:39to make them stronger.

00:31:40Today,

00:31:41they have more

00:31:42of a decorative purpose

00:31:43since they're distinctive

00:31:44and traditional for jeans.

00:31:47Another special thing

00:31:48about jeans

00:31:49is those tiny pockets

00:31:50they have

00:31:50that seemingly serve

00:31:52no purpose.

00:31:53Well,

00:31:53maybe it's true now,

00:31:54but years ago

00:31:55when many cowboys

00:31:56were wearing jeans,

00:31:57the pocket was made

00:31:58specifically

00:31:58to keep a pocket watch

00:32:00there.

00:32:01Also,

00:32:02back then,

00:32:02a pair of jeans

00:32:03had just four pockets,

00:32:04that tiny pocket,

00:32:06the watch pocket,

00:32:07two big pockets in front

00:32:08and just one pocket

00:32:09on the back.

00:32:12Many zippers

00:32:13have the letters

00:32:14YKK engraved on them.

00:32:16It's an abbreviation

00:32:17that stands for

00:32:18the name of the company

00:32:19that can be translated

00:32:20as

00:32:21Yoshida Manufacturing

00:32:22Shareholding Company.

00:32:24This Japanese company

00:32:25is the largest zipper

00:32:26manufacturer

00:32:27in the world,

00:32:28so they put their initials

00:32:29on all the zippers

00:32:30they produce.

00:32:30That's around half

00:32:31of the zippers

00:32:32in the world.

00:32:33And that's why

00:32:34you see their zippers

00:32:35more often

00:32:36than any other zippers.

00:32:39Those little white golf balls

00:32:40have dimples

00:32:41all over them.

00:32:42It turns out

00:32:42they aren't there

00:32:43just randomly.

00:32:44At first,

00:32:45golfers were playing

00:32:45with a smooth ball.

00:32:47With time,

00:32:48the ball would get

00:32:48all punched

00:32:49and damaged,

00:32:50but also,

00:32:51it would start

00:32:51to travel way further.

00:32:52The reason here

00:32:53is aerodynamics.

00:32:55Dimples allow the air

00:32:56to flow more smoothly

00:32:58around the ball,

00:32:59taking it further.

00:33:00So the idea was adopted

00:33:01and the balls

00:33:02got their dimples

00:33:02all around,

00:33:03allowing them to travel

00:33:04longer distances.

00:33:07For all those days

00:33:09when you barely have time

00:33:10for breakfast,

00:33:11there's an easy way

00:33:12to enjoy a nice

00:33:13and fast meal.

00:33:14And it will also save you

00:33:15the hassle of doing

00:33:16the dishes afterwards.

00:33:18I'm talking about

00:33:19instant oatmeal packets.

00:33:20Some manufacturers

00:33:22have added this neat design

00:33:24to the oatmeal.

00:33:25The packet is lined

00:33:26with plastic,

00:33:26so you can directly

00:33:28pour water or milk

00:33:29straight into it.

00:33:30This way,

00:33:31you won't have to

00:33:32use a bowl anymore.

00:33:34You place the liquid

00:33:35in and shake.

00:33:36Some packaging

00:33:37also has a demarcation line

00:33:39to show how much liquid

00:33:40should go inside the pack

00:33:41for that quantity.

00:33:44Next time you have

00:33:45to switch apartments,

00:33:46you won't have to worry

00:33:47about carrying

00:33:48that heavy box of books.

00:33:49These days,

00:33:51most moving boxes

00:33:52are specially designed

00:33:53for easy transportation

00:33:54with built-in handles.

00:33:56Well, they're not

00:33:57actually handled.

00:33:58I'll admit,

00:33:59they're basically just holes

00:34:00inside the cardboard box

00:34:02on the sides.

00:34:03But if you slip your hands in,

00:34:05you'll surely notice

00:34:06the boxes become

00:34:07way easier to carry

00:34:08than picking them up

00:34:09altogether.

00:34:11With the onset

00:34:12of so many online

00:34:14reading options

00:34:14like e-books

00:34:15or even apps

00:34:16on your phone

00:34:17that allow you

00:34:18to download novels,

00:34:19you've most likely

00:34:20forgotten

00:34:21about your local library.

00:34:22And hey,

00:34:23I'm not blaming you.

00:34:25But libraries these days

00:34:26offer a lot more services

00:34:28than you're used to,

00:34:29apart from free books

00:34:30and audiobook rental.

00:34:32Some of them

00:34:33have a variety

00:34:33of evening classes

00:34:35or can provide access

00:34:36to online courses.

00:34:38You may even be able

00:34:39to join a book club,

00:34:41which is a great way

00:34:41to meet new people,

00:34:42and you're guaranteed

00:34:43to get out of that

00:34:44reading slump

00:34:44you've been stuck in.

00:34:47I enjoy picking up

00:34:49dinner on my way home

00:34:50from my favorite

00:34:50takeout place

00:34:51just as you do.

00:34:52But if the food containers

00:34:53are not completely

00:34:54sealed shut,

00:34:55the ride back

00:34:56can prove itself

00:34:57quite the culinary experience,

00:34:58if you know what I mean.

00:35:00Especially

00:35:01for the carpets

00:35:02in your car.

00:35:04Some cars

00:35:05have a curry hook

00:35:06near the center console

00:35:07next to the driver's seat.

00:35:08It has been popular

00:35:09for 20 years

00:35:10and started as a handbag holder

00:35:12or a hook

00:35:12for a small shopping bag.

00:35:15But it quickly became

00:35:16the perfect way

00:35:17to store takeaway food

00:35:18and avoid spilling.

00:35:21I'm almost sure

00:35:22there's an umbrella

00:35:23somewhere in your car,

00:35:24but if I were to ask you

00:35:25where you're storing it,

00:35:26you'd most likely say

00:35:27the truck, of course.

00:35:29But is that really

00:35:29the best place to keep it?

00:35:32Wouldn't you want

00:35:32to have an umbrella

00:35:33at hand

00:35:34right when you get

00:35:35out of the car?

00:35:36Some car companies

00:35:37have thought about that

00:35:38and don't worry,

00:35:39they don't come

00:35:40with a built-in butler

00:35:41to help you get out

00:35:41of the car all dry.

00:35:44Some specific models

00:35:45have a designated place

00:35:46in the driver's door panel

00:35:48that perfectly fits

00:35:49an umbrella.

00:35:50You have to admit,

00:35:51it's an important thing

00:35:51to consider when researching

00:35:52your next car,

00:35:53more so if you live

00:35:55in a rainy location.

00:35:57Whenever I plan

00:35:58to travel to a new location,

00:36:00I like to have access

00:36:01to the local maps

00:36:02on my phone

00:36:02at any given time.

00:36:04Since you can't always

00:36:05foresee the quality

00:36:06or price of the internet

00:36:07in foreign countries,

00:36:08be sure to download

00:36:09the maps on your phone

00:36:10when connected to Wi-Fi.

00:36:13This way,

00:36:14you'll have easy access

00:36:15to all the must-see locations

00:36:17on your next city break,

00:36:18even if you run out

00:36:19of mobile data.

00:36:21The same goes

00:36:22for Google Translate.

00:36:23The mobile app

00:36:24comes with the option

00:36:25of downloading a language

00:36:26so you'll be able

00:36:27to use it offline.

00:36:29Another nice tip

00:36:30if you're more

00:36:31of the traveler type.

00:36:32If you own an iPhone,

00:36:34text an airline code

00:36:35and flight number

00:36:36to yourself.

00:36:37You'll then notice

00:36:38it will show up

00:36:39with an underline.

00:36:40When clicking on it,

00:36:41you'll be able

00:36:41to pull up flight data,

00:36:42like the gate

00:36:43the flight leaves from

00:36:44or if the flight

00:36:45is on schedule.

00:36:48Flashlights are those objects

00:36:50that we tend to reach out

00:36:51for in an emergency,

00:36:52like whenever there's

00:36:53a power break

00:36:54or when you need

00:36:55to take a quick trip

00:36:55in the attic

00:36:56for an old photo album

00:36:57or something.

00:36:58If you're ever

00:36:59in a sticky situation

00:37:00and the flashlight

00:37:01runs out of battery,

00:37:02have a look at its base

00:37:03under the battery spring.

00:37:05Some models come

00:37:06with a spare bulb

00:37:07hidden in there.

00:37:10If you're the type

00:37:11of person that likes

00:37:12to wake up early

00:37:12in the morning

00:37:13but the rest of the people

00:37:14in your house

00:37:15enjoy sleeping in,

00:37:16there's a way

00:37:16you can still use

00:37:17your microwave

00:37:18to prepare breakfast

00:37:19without waking everyone up.

00:37:21It turns out

00:37:22some of them come

00:37:23with a built-in mute function

00:37:24that gets rid of

00:37:25all the annoying rings

00:37:27and beeps.

00:37:29In the many times

00:37:30I've found myself

00:37:31driving on local roadways,

00:37:32I've noticed

00:37:33some apparently

00:37:34random blue reflectors

00:37:35here and there.

00:37:36Since I had no idea

00:37:38what they were,

00:37:38I did some research

00:37:39and found out

00:37:40they actually pinpoint

00:37:41the locations

00:37:42of fire hydrants.

00:37:43They're generally offset

00:37:44from the center line

00:37:45on either side

00:37:46and the offset side

00:37:48tells if the hydrant

00:37:49is on the left

00:37:50or right side of the road

00:37:51to assist firefighters

00:37:52on their missions better.

00:37:55Next time you get out

00:37:56of the car

00:37:57and forget to close

00:37:58all the windows,

00:37:58you won't have

00:37:59to get back in there.

00:38:01Just try this.

00:38:02Hold the keys

00:38:03on the door

00:38:03of your car pressed

00:38:04and it should lock

00:38:05all the doors

00:38:06and shut all the windows.

00:38:08The same goes

00:38:09with opening all the doors.

00:38:11Just double click

00:38:11the button.

00:38:13Most car models

00:38:14should come

00:38:14with this added option

00:38:15but most people

00:38:16just forget

00:38:17or have no idea

00:38:18that they can do that.

00:38:20Whenever you're

00:38:21in that awkward position

00:38:22of messing up

00:38:23a voicemail,

00:38:24do you know

00:38:25there's a way

00:38:25you can delete

00:38:26or re-record the message

00:38:27saving you

00:38:28the unnecessary embarrassment?

00:38:30Stay online

00:38:31after recording

00:38:32the message

00:38:32and dial either pound,

00:38:34number sign,

00:38:35or star,

00:38:35asterix

00:38:36to access

00:38:37the voicemail menu.

00:38:38Further instructions

00:38:39should be provided

00:38:40so you can decide

00:38:41what to do

00:38:41with the recording.

00:38:44Bagels are becoming

00:38:45more and more famous

00:38:47these days

00:38:47on options

00:38:48for breakfast

00:38:48or snacks

00:38:49because they're

00:38:50so tasty

00:38:51and so versatile.

00:38:52The problem is

00:38:53I only want

00:38:54my bagel toasted

00:38:55on one side.

00:38:56Thankfully,

00:38:57some toasters

00:38:58come with a bagel setting

00:38:59which ensures

00:39:00the pastry

00:39:01is toasted

00:39:01on either one

00:39:02of the two sides.

00:39:06Ever wondered

00:39:06why manhole covers

00:39:07only come

00:39:08in that round shape?

00:39:09It turns out

00:39:10that this is

00:39:11the only shape

00:39:11that cannot fall

00:39:12through the hole

00:39:13altogether.

00:39:14Any other shape,

00:39:15especially shapes

00:39:16with corners,

00:39:17could be rotated

00:39:17so that the lid

00:39:18could fall through.

00:39:21Here's a neat one

00:39:22if you enjoy

00:39:22a little massage

00:39:23whenever you're

00:39:24taking a shower.

00:39:25On most of the

00:39:26shower heads

00:39:26available these days,

00:39:27there should be

00:39:28a small metal filter

00:39:29in the back

00:39:30beneath the shower head

00:39:31once you unscrew it.

00:39:33If you give this piece

00:39:34a rough cleaning

00:39:35once in a while,

00:39:36you'll find the water pressure

00:39:37to be greatly improved.

00:39:41You may be able

00:39:42to save that wool sweater

00:39:43you've accidentally

00:39:44thrown in the washer

00:39:44and has shrunken

00:39:45down three sizes.

00:39:47Just go in the shower

00:39:48and grab a bottle

00:39:49of hair conditioner.

00:39:50Add it to some cold water

00:39:52in a tub

00:39:52and make a solution

00:39:53and let the garment

00:39:55sit there for at least

00:39:55a couple of hours.

00:39:57The conditioner

00:39:58should help relax

00:39:59the wool fibers

00:40:00and loosen them back up,

00:40:02not to mention

00:40:02how nice it should smell

00:40:04afterwards.

00:40:06You might need

00:40:07to do a bit of research

00:40:09before you can safely

00:40:10use this trick.

00:40:11But just so that you know,

00:40:12there are some modern laptops

00:40:14with drainage channels.

00:40:15Mm-hmm,

00:40:16you heard that right.

00:40:17Precisely when you accidentally

00:40:18spilled coffee on it,

00:40:20they're designed to ensure

00:40:21any liquid that gets

00:40:22on the keyboard

00:40:22safely drains out

00:40:24at the bottom

00:40:24without damaging

00:40:25the electrical parts.

00:40:27Just make sure

00:40:28to not shake the laptop

00:40:29after you've spilled the liquid

00:40:30so that the system

00:40:31can do its job correctly.

00:40:38You got used to browsing the web,

00:40:41playing games,

00:40:41and connecting with your friends

00:40:43on social media,

00:40:44all at the convenience

00:40:45of the iPhone in your pocket.

00:40:47But what if I were to tell you

00:40:48that there were many more

00:40:50hidden uses inside it?

00:40:52Back tap

00:40:54Have you ever noticed

00:40:55that fancy Apple logo

00:40:57on the back of your iPhone?

00:40:58If you've got a cover on,

00:41:00go ahead and pull it off

00:41:02so you can check it out.

00:41:04Okay,

00:41:04you're now probably thinking,

00:41:06there's nothing secret about this,

00:41:08the obvious brand logo

00:41:09on my iPhone.

00:41:11Sure,

00:41:11it might not seem so special,

00:41:13but did you know

00:41:14that it's more than just

00:41:15a handsome decoration?

00:41:17It's also,

00:41:18as a matter of fact,

00:41:19a button.

00:41:20Don't believe me?

00:41:22Give it a try.

00:41:24But,

00:41:25before you go tapping at it

00:41:27like you're using

00:41:27your phone backward,

00:41:28you'll need to adjust

00:41:29your settings.

00:41:30There's a reason

00:41:31this handy feature

00:41:32is considered a secret.

00:41:34First,

00:41:35pull up your settings,

00:41:36tap on accessibility,

00:41:38and then,

00:41:39the touch menu,

00:41:40and navigate your way

00:41:41to the very bottom

00:41:42of the list,

00:41:43where you'll find

00:41:44the back tap button.

00:41:46Found it?

00:41:47Great!

00:41:47You can choose

00:41:49the double tap

00:41:50or triple tap option,

00:41:51whichever you prefer,

00:41:53and best of all,

00:41:54you'll have a multitude

00:41:55of options to choose from.

00:41:58You can have

00:41:58your back tap feature

00:41:59take a photo

00:42:00with your camera app,

00:42:01alert Siri,

00:42:03switch apps,

00:42:04and even take a screenshot.

00:42:06It'll make things

00:42:07a lot easier

00:42:08than performing

00:42:09finger gymnastics

00:42:10when you need

00:42:11to take a screenshot.

00:42:12Adjust Siri's

00:42:13pronunciations.

00:42:16Have you ever asked

00:42:17Siri to call a friend?

00:42:19Maybe you've said,

00:42:20Siri,

00:42:20call Hermione,

00:42:22only for Siri

00:42:23to comply with

00:42:24calling Hermione.

00:42:27Okay,

00:42:28you may not have

00:42:28Harry Potter's best friend

00:42:30in your contacts list,

00:42:31but we can all agree

00:42:32it's not the easiest

00:42:34name to pronounce.

00:42:35Siri might be one

00:42:37of the most intelligent

00:42:38digital assistants

00:42:39in the smartphone game,

00:42:40and sometimes

00:42:41a bit of a smarty pants,

00:42:43but iPhone's companion

00:42:45can often struggle

00:42:46to pronounce

00:42:47even the most common names.

00:42:48If this bothers you,

00:42:50then you'd be delighted

00:42:51to hear you can

00:42:52actually correct

00:42:54Siri's pronunciations.

00:42:55The simplest way

00:42:56is to catch Siri

00:42:58in the act

00:42:58and say,

00:42:59that's not how

00:43:00you pronounce.

00:43:01It will prompt

00:43:02Siri to ask for

00:43:03the correct pronunciation

00:43:04for each name,

00:43:06first, middle,

00:43:07and last,

00:43:08or the name of a place

00:43:10if it's not for a person.

00:43:12Once you've given it,

00:43:13Siri will generate

00:43:14some options

00:43:15and all you have to do

00:43:16is pick the correct one.

00:43:18If your digital best friend

00:43:20is still struggling,

00:43:21it might help

00:43:22to spell it out.

00:43:23Open your contacts,

00:43:25select the person

00:43:26Siri is struggling

00:43:27to pronounce

00:43:27and choose Edit.

00:43:30You can add

00:43:31the correct pronunciation

00:43:32in the Notes section

00:43:33using phonetic spelling

00:43:35and click

00:43:35Pronunciation Spelling

00:43:37to train Siri

00:43:38to get it right.

00:43:39Even a super smart

00:43:41digital assistant

00:43:42needs some help sometimes.

00:43:44Hey Siri,

00:43:45it's Leviosa,

00:43:46not Leviosar.

00:43:49Measure app

00:43:51Is a toolkit

00:43:52too clunky

00:43:52to carry around?

00:43:53Or maybe you've forgotten

00:43:55which drawer

00:43:56you place the measuring tape in?

00:43:57That's okay.

00:43:59iPhone has got

00:44:00some more secrets

00:44:00that will help you out.

00:44:02Did you know

00:44:02that iPhone

00:44:03has a few tools

00:44:04in its arsenal

00:44:05that will serve

00:44:06your carpentry needs?

00:44:07Take the measure app,

00:44:09for instance.

00:44:09You no longer need

00:44:10that long,

00:44:11awkward-to-use floppy tape

00:44:13to get a measurement

00:44:14on your coffee table,

00:44:15bookshelf,

00:44:16or couch.

00:44:18The app uses

00:44:20augmented reality

00:44:21to measure objects

00:44:22around you

00:44:23using your phone's camera.

00:44:25The first thing

00:44:26you'll need to do

00:44:26is move your phone around

00:44:28so the app

00:44:29can analyze the area

00:44:30you intend to measure.

00:44:32You'll eventually find

00:44:33a white circle

00:44:34with a dot

00:44:35in the middle

00:44:36of your screen.

00:44:37From there,

00:44:38it's not so different

00:44:39from an actual

00:44:40measuring tape.

00:44:40Just line up the dot

00:44:42with the corner

00:44:43of the object

00:44:43you want to measure

00:44:44and trace it

00:44:46to where you want

00:44:46the measurement to end.

00:44:48If you're a builder,

00:44:49you might want to stick

00:44:50to the physical tape

00:44:51for more accurate measurement.

00:44:53This option

00:44:54isn't necessarily

00:44:55for the professionals.

00:44:57But the app

00:44:58is excellent

00:44:59for getting a rough estimate.

00:45:01The measure app

00:45:02can also be used

00:45:03as a level.

00:45:04Simply switch over

00:45:06to the level tab

00:45:07in your app

00:45:07and place your phone

00:45:09on the surface

00:45:09where you want

00:45:10to get a reading.

00:45:11When you get

00:45:12a green screen

00:45:13and a zero reading,

00:45:15your surface

00:45:15is nice and level.

00:45:17It's not so different

00:45:19from the compass app's

00:45:20level feature,

00:45:21so you might have

00:45:22had some bad experiences

00:45:24with this feature before.

00:45:25With your new

00:45:26digital toolbox,

00:45:27your iPhone

00:45:28will make you

00:45:29the handiest person

00:45:30in the house.

00:45:32Create Custom Vibration

00:45:35We all live

00:45:36pretty fast-paced

00:45:37and busy lives

00:45:38these days.

00:45:39And whether we're

00:45:40at work,

00:45:40in a movie,

00:45:41or at school,

00:45:42more often than not,

00:45:44we have our iPhone

00:45:45set to vibrate.

00:45:47Sure,

00:45:48there are some

00:45:49cool ringtones

00:45:50to choose from.

00:45:50But there aren't

00:45:52many occasions

00:45:52where a sudden tune

00:45:53coming from our pocket

00:45:55wouldn't distract

00:45:56those around us.

00:45:57Or worse yet,

00:45:58it leads to our phone

00:45:59being confiscated

00:46:00by a disgruntled

00:46:01employer or teacher.

00:46:03Luckily,

00:46:04there are plenty

00:46:05of vibration options

00:46:06to choose from.

00:46:07You probably have

00:46:08various ones

00:46:09for different occasions

00:46:10and different contacts.

00:46:12None of those settings

00:46:13quite your jam?

00:46:14Apple has a solution

00:46:15to this too.

00:46:16Another hidden feature

00:46:17in the iPhone

00:46:18is creating

00:46:19a custom vibration

00:46:20for your alerts.

00:46:22If you want

00:46:23to feel the beat

00:46:24to your favorite song

00:46:25when your best friend

00:46:26calls or texts,

00:46:27or when it's time

00:46:28to wake up in the morning,

00:46:29you create that pattern

00:46:31on your iPhone.

00:46:32Once again,

00:46:33you'll need to go

00:46:34into those handy settings.

00:46:36Then,

00:46:36in Sound and Haptics,

00:46:38choose the tone

00:46:39you'd like to customize.

00:46:40Tap Vibration.

00:46:42Then,

00:46:43create new vibration.

00:46:45The next step

00:46:46is to create

00:46:47those sweet vibrations

00:46:48like a soundless DJ

00:46:50by tapping your finger

00:46:51on the screen

00:46:52until you have

00:46:53the silent rhythm

00:46:54you're happy with.

00:46:55Now you've got

00:46:56a vibrate option

00:46:57to your liking.

00:46:59It might even make

00:47:01the early morning

00:47:01wake-up calls

00:47:02just a little more pleasant.

00:47:04Just like the Beach Boys,

00:47:05you'll be

00:47:06picking up good vibrations.

00:47:09Trackpad.

00:47:11With smartphones,

00:47:13we no longer need

00:47:14two hands

00:47:14to use a keyboard.

00:47:16All you need

00:47:16is one good thumb.

00:47:18Yet,

00:47:19it can still prove

00:47:20a little tedious sometimes

00:47:21as typos

00:47:22are easy to make

00:47:23and all your characters

00:47:25can't fit all at once

00:47:26on that crammed keyboard

00:47:27at the bottom

00:47:28of your phone screen.

00:47:29You might be typing out

00:47:31a long body of text

00:47:32only to realize

00:47:33you left out the R

00:47:35out of the word drive

00:47:36a few sentences back

00:47:37which might give your friends

00:47:39the wrong idea

00:47:40about what you're doing.

00:47:41It can be a fiddly task

00:47:43to fix it

00:47:43and it's often easiest

00:47:45to delete the entire word

00:47:46and write it all over again

00:47:48or so it may seem.

00:47:50If you're a stickler

00:47:51for good grammar

00:47:52in your text messages,

00:47:53you might want

00:47:54to shift your keyboard

00:47:55into trackpad mode

00:47:56for easier editing.

00:47:58That's right,

00:47:59another hidden gem

00:48:00on your iPhone.

00:48:01It's easy to access too.

00:48:03All you have to do

00:48:04is hold your finger

00:48:05on the space bar.

00:48:07All the other keys

00:48:08will gray out

00:48:09and you'll be able

00:48:10to move the cursor

00:48:11to wherever it needs to go.

00:48:13Then,

00:48:14lift your finger

00:48:15off the space bar

00:48:16to continue typing.

00:48:17Another tedium

00:48:18to writing

00:48:19on that tiny iPhone keyboard

00:48:20is shifting tabs

00:48:22to use numbers

00:48:23and symbols.

00:48:24It may not seem like much

00:48:26but it's sure

00:48:26to be a little frustrating

00:48:28when you have to jump

00:48:29back and forth

00:48:29multiple times

00:48:30in the same message.

00:48:32However,

00:48:33there is another hidden feature

00:48:34in your iPhone's keyboard

00:48:36that will alleviate this.

00:48:38Hold it down

00:48:39instead of tapping

00:48:40on the numeric

00:48:41123 tab

00:48:42and it will bring up

00:48:43the numbers

00:48:44and symbols tab.

00:48:45As long as you're holding it,

00:48:46the tab will remain open

00:48:48to pick your character

00:48:49and releasing

00:48:50will return you to letters.

00:48:52Soon,

00:48:53you'll be fast enough

00:48:54to write a novel

00:48:55on your smartphone.

00:48:56Did you ever tie a string

00:48:57between two plastic cups

00:48:59so you could talk

00:49:00to your friend

00:49:00from opposite ends

00:49:01of your home?

00:49:02It may have seemed

00:49:03pretty cool at the time

00:49:04but that plastic cup

00:49:06couldn't tell you

00:49:07the weather

00:49:07or let you send

00:49:08an email, right?

00:49:09Indeed,

00:49:10we've come a long way

00:49:11since the string telephone.

00:49:13In fact,

00:49:13can you even imagine

00:49:15life before smartphones?

00:49:16They have become

00:49:17almost like our clothes

00:49:19or the shoes we walk in.

00:49:20It's almost

00:49:21our consistent accessory.

00:49:23Now you know

00:49:24some of these handy secrets

00:49:25and you'll be

00:49:26an iPhone pro.

00:49:27However,

00:49:28if these secrets

00:49:29aren't for you,

00:49:30there's always

00:49:31the string telephone.

00:49:32At least it won't

00:49:33run out of charge.

00:49:36Have you ever

00:49:37stopped to think

00:49:38about the thrilling secrets

00:49:40of day-to-day

00:49:41modern life

00:49:42on planet Earth?

00:49:43I'm talking about

00:49:44tiny windows

00:49:45and washing machines

00:49:46and little holes

00:49:47in airplane windows.

00:49:49If you haven't

00:49:50got a clue

00:49:51of what I'm talking about,

00:49:52tag along

00:49:53and allow yourself

00:49:54to be as surprised

00:49:55as I was

00:49:56when I found out.

00:49:59Remember the drawer

00:50:00at the bottom

00:50:01of your oven?

00:50:02Maybe you've been

00:50:02ignoring it all along

00:50:04or using it

00:50:05to store pots and pans.

00:50:06Well,

00:50:07even though

00:50:07it can serve

00:50:08this function,

00:50:09that's not the only

00:50:10thing it's there for.

00:50:11The best way

00:50:12to use the bottom drawer

00:50:14is to keep your meal

00:50:15heated while you're

00:50:16waiting to serve it.

00:50:17Genius, right?

00:50:19Talking about

00:50:20secret doors,

00:50:21have you noticed

00:50:22that most washing machines

00:50:24have little flap doors

00:50:25at the bottom too?

00:50:26These doors actually

00:50:28serve as drain traps.

00:50:30It's where all the items

00:50:31that we put to wash

00:50:32together with our jeans

00:50:33and jackets go to.

00:50:35It's a type of collector,

00:50:37let's say,

00:50:37of small items.

00:50:39It stops them

00:50:40from getting into

00:50:41the main drain pipes

00:50:42and clogging them.

00:50:43It saves us

00:50:44hundreds of dollars

00:50:45in repairs each month.

00:50:48Now,

00:50:49who hasn't gone

00:50:50through the confusing task

00:50:51of having to measure

00:50:52how much pasta

00:50:53to cook

00:50:54for one serving?

00:50:55Well,

00:50:56here's the solution.

00:50:57The holes

00:50:58in the center

00:50:59of pasta spoons.

00:51:00They were actually

00:51:01made for measuring

00:51:02the exact amount

00:51:03of dry pasta

00:51:04you need

00:51:05for one serving.

00:51:06If you try stuffing

00:51:07wet cooked pasta

00:51:09through it,

00:51:10well,

00:51:10good luck with that.

00:51:12On a similar topic,

00:51:14have you ever wondered

00:51:15why pen caps

00:51:16have holes in them?

00:51:17Maybe you thought

00:51:18it was a design feature

00:51:20to regulate air pressure.

00:51:21But in reality,

00:51:23these holes have

00:51:23a much simpler

00:51:24and more important function

00:51:26to reduce the risk

00:51:27of choking.

00:51:29Now,

00:51:29lots of people

00:51:30love to bite

00:51:31on their caps,

00:51:32and this tiny hole

00:51:33prevents them

00:51:34from choking

00:51:34in case they accidentally

00:51:36swallow a cap

00:51:37and it gets stuck

00:51:38in their throat.

00:51:39For kitchen lovers,

00:51:41there's a hidden secret

00:51:42right in front of your eyes

00:51:43that can change your life.

00:51:45Think pans.

00:51:47Now,

00:51:47think handles.

00:51:48Right!

00:51:49They have holes in them.

00:51:50As it turns out,

00:51:52these holes were designed

00:51:53to hold the spoon

00:51:54you're using for cooking.

00:51:56And instead of dripping sauce

00:51:57all over the stove

00:51:59or your kitchen floor,

00:52:00you can place the spoon

00:52:02in the hole

00:52:03and let it drip the sauce

00:52:04directly back into the pan.

00:52:06Woo-hoo!

00:52:08Speaking of everyday items,

00:52:10and I was,

00:52:12most doorknobs

00:52:13are made of brass

00:52:14because this material

00:52:15makes them naturally

00:52:16germ-free.

00:52:17Unlike plastic ones,

00:52:20brass doorknobs

00:52:20are kind of magical.

00:52:22They can disinfect themselves

00:52:24without you having

00:52:25to clean them.

00:52:26Neat, right?

00:52:28Have you ever noticed

00:52:29that at the bottom

00:52:30of a measuring tape

00:52:31there is a little dip?

00:52:33You can find it

00:52:34in that metallic part

00:52:35you need to pull on

00:52:36to measure something.

00:52:38Well,

00:52:38that dip

00:52:39is actually

00:52:40the exact size

00:52:41of a regular nail.

00:52:43It was designed

00:52:44for people

00:52:44to place the tape

00:52:45on top of a nail

00:52:46and use it as a support

00:52:48while they stretch the tape.

00:52:50Well,

00:52:50I can't wait

00:52:51to try it out for myself.

00:52:53As for the margins

00:52:55in your notebook,

00:52:56they were invented

00:52:57to protect people's notes

00:52:58from mice.

00:53:00No,

00:53:01the mice weren't

00:53:01copying your answers

00:53:03for the math quiz.

00:53:04Actually,

00:53:05there were times

00:53:06when people

00:53:07had to cohabitate

00:53:08with rats and mice

00:53:09that often chewed

00:53:10on paper.

00:53:11So,

00:53:12to prevent information

00:53:13from getting

00:53:14completely lost,

00:53:15people created margins.

00:53:17This way,

00:53:18texts were moved

00:53:19closer to the middle

00:53:20of pages

00:53:21and remained

00:53:22unharmed

00:53:23by rodents.

00:53:25perhaps this is

00:53:26where

00:53:26to digest

00:53:27information

00:53:28came from.

00:53:30And what about

00:53:31those tiny holes

00:53:32at the bottom

00:53:32of airplane windows?

00:53:34They have

00:53:35an extremely

00:53:36important function

00:53:37of regulating

00:53:38the air pressure

00:53:39inside the cabin.

00:53:40In other words,

00:53:42they help planes

00:53:42fly high up

00:53:44in the sky.

00:53:44Big responsibility,

00:53:46right?

00:53:47By the way,

00:53:48tray tables

00:53:49on an airplane

00:53:50are the germiest

00:53:51places

00:53:52inside the entire cabin.

00:53:54Studies showed

00:53:55that the trays

00:53:56had eight times

00:53:57the amount of germs

00:53:58on the toilet flush button.

00:54:01Now,

00:54:02how about we cut

00:54:03a commercial airplane

00:54:04in half

00:54:05and see what's inside?

00:54:07Well,

00:54:07it would look

00:54:08more or less

00:54:09like this.

00:54:10Rows of seats

00:54:11on top

00:54:11and everything else

00:54:12that needs to be stored

00:54:13at the bottom.

00:54:15I'm talking about

00:54:16passengers' luggage,

00:54:17emergency supplies,

00:54:19parts of the wing system,

00:54:20and so on.

00:54:22Moving on

00:54:23to bowling balls.

00:54:24Yes,

00:54:25I know

00:54:25it's a clumsy transition.

00:54:28Anyway,

00:54:29have you ever wondered

00:54:30what the insides

00:54:31of a bowling ball

00:54:32look like?

00:54:33If you have cut

00:54:34a professional ball

00:54:35in two,

00:54:36you'll see

00:54:37a familiar shape.

00:54:38Look closely.

00:54:39Do you see it?

00:54:40Doesn't that look

00:54:41like the logo

00:54:42of Brightside?

00:54:43Anyway,

00:54:44professional bowling balls

00:54:45are different

00:54:46from the ones

00:54:47in your local

00:54:47bowling alley.

00:54:48That's because

00:54:49they're designed

00:54:50to make fancy moves.

00:54:52They actually have

00:54:53some really complex

00:54:54engineering inside.

00:54:55They're shaped

00:54:56to help skilled

00:54:57professionals

00:54:57get more strikes.

00:54:59The weight

00:54:59of professional

00:55:00bowling balls

00:55:01is designed

00:55:02to be projected

00:55:02inward

00:55:03as they travel

00:55:04down the bowling lane.

00:55:06This makes it

00:55:06harder for them

00:55:07to get into the gutters

00:55:08on the sides

00:55:09of the lane.

00:55:11Speaking of balls,

00:55:13let's take a look

00:55:14inside a baseball.

00:55:15To make it light

00:55:16and aerodynamic,

00:55:18producers use

00:55:19several different layers.

00:55:20Starting from the core,

00:55:22we have a cork center

00:55:23enveloped by black rubber.

00:55:25Then,

00:55:26there's a layer

00:55:27of red rubber

00:55:28followed by two

00:55:29or three alternating

00:55:30layers of wool yarn.

00:55:32After that,

00:55:33there's a visible

00:55:34white leather cover

00:55:35and that beautiful

00:55:36red seam on the side,

00:55:38stitching it all together.

00:55:40And,

00:55:41what if you had

00:55:42x-ray vision

00:55:43and managed to look

00:55:44inside a human bone,

00:55:46ooh,

00:55:47spooky?

00:55:48I'd say

00:55:49what calls

00:55:49most attention

00:55:50is this spiderweb-like

00:55:52situation

00:55:52at the center

00:55:53of the bone.

00:55:54In reality,

00:55:55it's a highly condensed

00:55:56and complex

00:55:57structure of nerves

00:55:58that you have

00:55:59inside your bones.

00:56:01Aren't you lucky?

00:56:03Now,

00:56:04I've got a riddle

00:56:05for you.

00:56:05What is round

00:56:06can be found

00:56:07near the ocean

00:56:08and looks like

00:56:09an aerial view

00:56:10of the Guggenheim Museum

00:56:11in New York City,

00:56:12the one that's made

00:56:14almost entirely

00:56:15of ramps.

00:56:15If you said

00:56:17a nautilus shell,

00:56:18hey,

00:56:19then you guessed right.

00:56:20A nautilus

00:56:21is a shellfish

00:56:22whose house

00:56:23you can find

00:56:24in countless

00:56:24souvenir stores

00:56:25near the beach.

00:56:26It's made up

00:56:27of two layers,

00:56:28a matte white

00:56:29outer layer

00:56:30and an iridescent

00:56:32white inner layer.

00:56:33And,

00:56:34if you were to cut

00:56:34it in half,

00:56:35it would look

00:56:36very similar

00:56:37to the insides

00:56:38of the Guggenheim Museum.

00:56:40Aloe leaves

00:56:41are good

00:56:41for healing purposes

00:56:42and also

00:56:43for hydration.

00:56:45But,

00:56:45if you managed

00:56:46to look inside

00:56:47of an aloe leaf,

00:56:49the image you'd see

00:56:50would be satisfying

00:56:51and very relaxing.

00:56:53Who hasn't dreamed

00:56:54of a pool

00:56:55filled with jelly?

00:56:57Now,

00:56:58there seems to be

00:56:58nothing more mundane

00:57:00and regular

00:57:01than a tube

00:57:01of toothpaste.

00:57:02But,

00:57:03you wouldn't think so

00:57:04if you cut open

00:57:05a tube

00:57:05that contains

00:57:06several colors.

00:57:07Now,

00:57:08there have been

00:57:09speculations

00:57:10that the insides

00:57:11of such a toothpaste tube

00:57:12might be divided

00:57:13by barriers

00:57:14so that the stripes

00:57:16don't mix.

00:57:17But,

00:57:17if you cut it in half,

00:57:19you'll see that

00:57:20it has only

00:57:20one interior chamber.

00:57:23As it happens,

00:57:24there's a lot of science

00:57:25behind the making

00:57:26of striped toothpaste.

00:57:28According to a specialist,

00:57:30they have to ensure

00:57:31that the paste

00:57:31in all the stripes

00:57:32has the same

00:57:33physical properties.

00:57:35This way,

00:57:36the colors

00:57:36are naturally

00:57:37prevented

00:57:37from mixing

00:57:38with one another.

00:57:39That's why,

00:57:40if you tear

00:57:40a tube open,

00:57:41you'll see something

00:57:42that looks like

00:57:43several slices

00:57:44of pizza

00:57:44in different colors.

00:57:47If you open

00:57:48your closet,

00:57:49you're bound

00:57:49to find

00:57:49at least a few

00:57:50wooden hangers.

00:57:52Usually,

00:57:52they're made

00:57:53of cedar wood,

00:57:54which is a natural

00:57:55moth repellent.

00:57:57So,

00:57:57cedar hangers

00:57:58actually protect

00:57:59your clothes

00:58:00from moth infestation.

00:58:02For some people,

00:58:03more than others,

00:58:04eyeliner

00:58:05is an everyday must.

00:58:06Boy,

00:58:07isn't it?

00:58:08But,

00:58:08did you know

00:58:09that back in

00:58:10ancient Egyptian times,

00:58:12both men and women

00:58:13used cool eyeliners

00:58:15to protect their eyes

00:58:16from the sun's glare?

00:58:17Way to go

00:58:18for the Egyptians

00:58:19for figuring that out!

00:58:21Now,

00:58:21if I could just learn

00:58:22to walk like one!

00:58:25Normally,

00:58:25we use headrests

00:58:27for the purpose of,

00:58:28well,

00:58:29resting our heads,

00:58:30right?

00:58:31Well,

00:58:31not only!

00:58:32As it turns out,

00:58:34headrests can be

00:58:35easily removed

00:58:36from the seats

00:58:37and used to break

00:58:38car windows

00:58:39in case of emergencies.

00:58:41Now,

00:58:42this one is a trick

00:58:43very few people know about.

00:58:45You probably place

00:58:46your doormat horizontally,

00:58:48like most of us do.

00:58:49But doormats

00:58:50serve the purpose

00:58:51of absorbing dirt

00:58:53from the soles

00:58:53of your shoes

00:58:54before you enter

00:58:55your home.

00:58:56So,

00:58:57for this function

00:58:57to work as it's meant to,

00:58:59the best way

00:59:00to place a doormat

00:59:01is vertically.

00:59:03This way,

00:59:03you take more steps

00:59:05on the top

00:59:05of the doormat

00:59:06before entering

00:59:07your house.

00:59:09And,

00:59:09last but not least,

00:59:11now,

00:59:12I don't want to be

00:59:12accusatory here,

00:59:13but you have probably

00:59:15been vacuuming

00:59:16your house

00:59:16the wrong way,

00:59:17and I can prove it.

00:59:19Most people

00:59:20just vacuum floors

00:59:21and carpets

00:59:22in one direction

00:59:23or move the brush

00:59:24back and forth

00:59:25several times,

00:59:26thinking they've got

00:59:27all the dust out.

00:59:29But,

00:59:29according to

00:59:30cleaning professionals,

00:59:31the best way

00:59:32to vacuum

00:59:32is in rows.

00:59:34First,

00:59:34you go forward

00:59:35with the brush

00:59:36until you arrive

00:59:36at the end of the row.

00:59:38Then,

00:59:39you fluff the carpet up

00:59:40and move back down

00:59:41along the same row,

00:59:43gathering the dust

00:59:44that wasn't collected

00:59:45in the first sweep.

00:59:46Talk about

00:59:47efficient cleaning.

00:59:48On the other hand,

00:59:50my idea of house cleaning

00:59:51is to sweep the room

00:59:53with a glance.

00:59:54Hey,

00:59:55I don't want to disturb

00:59:56that protective layer

00:59:57of dust.

01:00:00You just spent

01:00:01the entire morning

01:00:02running errands

01:00:03up and down the street,

01:00:04and you finally stop

01:00:05to treat yourself

01:00:06to a cup of coffee.

01:00:07You enter the nearest

01:00:08coffee shop,

01:00:09place your order,

01:00:10and notice that,

01:00:11actually,

01:00:12you really need

01:00:13to use the bathroom.

01:00:14It's a regular-looking

01:00:15public one

01:00:16with multiple stalls.

01:00:18As you pick yours,

01:00:19the one in the middle,

01:00:20you get inside,

01:00:21and your mind

01:00:22starts to wander.

01:00:23Why on earth

01:00:24do bathroom doors

01:00:25have a half-inch gap

01:00:26between the door

01:00:27and the lock?

01:00:28And why on earth

01:00:29do they have a huge gap

01:00:30between the door

01:00:31and the floor?

01:00:32Can we have a drumroll

01:00:33for this moment,

01:00:34please?

01:00:35Well, my friend,

01:00:36there is not only

01:00:37one specific reason

01:00:38why public bathroom doors

01:00:40have so many gaps in them,

01:00:42but rather several.

01:00:43Public toilets

01:00:44are designed

01:00:45to make people spend

01:00:46as little time

01:00:47there as possible.

01:00:48You aren't supposed

01:00:49to feel comfortable

01:00:49or at home.

01:00:51So, the design

01:00:52would have to reflect

01:00:53this notion.

01:00:53Here come the gaps.

01:00:55In some bathrooms,

01:00:57gaps are so big

01:00:58that users may even

01:00:59feel self-conscious

01:01:00about doing their business

01:01:02out of preoccupation

01:01:03that the rest of the people

01:01:04standing in line

01:01:05will see them.

01:01:07Then, there's the matter

01:01:08of pricing.

01:01:09Making custom doors

01:01:10can be a heavy burden

01:01:11for the people

01:01:12building public toilets.

01:01:13This would mean

01:01:14understanding

01:01:15exact measurements

01:01:16so that doors

01:01:17would always fit

01:01:18the mold of the stalls

01:01:19it's supposed

01:01:19to be installed into.

01:01:21Now, not all the gaps

01:01:23in public bathrooms

01:01:24are necessarily

01:01:25the same size.

01:01:26They may vary,

01:01:27even if this variation

01:01:29is small

01:01:29and often unnoticeable.

01:01:31So, these gaps

01:01:32actually help

01:01:33to reduce the margins

01:01:34of errors

01:01:34and to turn production

01:01:36more cost-effective

01:01:37for the people

01:01:38financing them.

01:01:39In case a door

01:01:40comes wider

01:01:41or more narrow

01:01:42than it should,

01:01:43the gap regulates

01:01:44the differences

01:01:44and allows for

01:01:45their installation anyway.

01:01:47There is also

01:01:48the case of air circulation.

01:01:50The last thing

01:01:51you want to do

01:01:52in a public bathroom

01:01:53is to trap odors.

01:01:54So, you need

01:01:55a little space

01:01:56under and between

01:01:57the doors

01:01:57to allow the air

01:01:58to flow.

01:02:00Finally,

01:02:00the gaps are

01:02:01a big safety measure.

01:02:02It can always allow

01:02:03for people

01:02:04on the outside

01:02:04to see if someone

01:02:06inside a stall

01:02:07isn't feeling too okay

01:02:08and maybe

01:02:09needs some help.

01:02:10And, what about

01:02:11that extra hole

01:02:12in the upper part

01:02:13of the sink?

01:02:14It has a name

01:02:15in everything

01:02:15the overflow hole

01:02:17and it's designed

01:02:18to keep the sink

01:02:19from flooding.

01:02:20So, in case

01:02:21someone forgets

01:02:22and keeps the faucet

01:02:22going for too long

01:02:23or the sink

01:02:24gets clogged

01:02:25and water

01:02:26can't drain down

01:02:27from the main drain hole,

01:02:28the overflow hole

01:02:29comes in

01:02:30to save the day.

01:02:31Let's say

01:02:32it buys you

01:02:32a little time

01:02:33before you have

01:02:34the entire bathroom

01:02:35floor flooded.

01:02:36Have you ever noticed

01:02:37how satisfying

01:02:38closing the door

01:02:39of a car can be?

01:02:41Car manufacturers

01:02:42devote a great deal

01:02:43of time

01:02:43to designing

01:02:44these sounds.

01:02:45Studies have shown

01:02:46that they create

01:02:47a perceived sense

01:02:47of quality

01:02:48in the buyer.

01:02:49It all begins

01:02:50with the primary material.

01:02:52While older cars

01:02:53used to be made

01:02:54with heavier materials,

01:02:55car doors nowadays

01:02:56are produced

01:02:57with lighter tin

01:02:58which can make

01:02:59a rather unpleasant

01:03:00metallic sound

01:03:01once you shut

01:03:02them closed.

01:03:03So, car companies

01:03:04employ sound engineers

01:03:05to ensure

01:03:06that there is

01:03:07the exact amount

01:03:08of foam, mats,

01:03:09and tin

01:03:09in a car's composition

01:03:11to make the most

01:03:12comforting sound

01:03:13possible.

01:03:13And what about

01:03:15those tiny dots

01:03:16on the top

01:03:16of your car's

01:03:17front window?

01:03:18The pattern

01:03:19of these little

01:03:19black dots

01:03:20minimizes distractions

01:03:21for your eyes.

01:03:22This black part,

01:03:23also known as frit,

01:03:25normally gets warmer

01:03:26than the clear parts,

01:03:27which prevents

01:03:28the windshield

01:03:29from deforming.

01:03:30And no,

01:03:31the tab under

01:03:32your rearview mirror

01:03:33is not made only

01:03:34for the purpose

01:03:34of hanging

01:03:35fluffy dice

01:03:36or aromatic-pleasing

01:03:37air fresheners.

01:03:38It's actually a switch

01:03:39that allows you

01:03:40to adjust the position

01:03:41of the mirror

01:03:42depending on

01:03:43the time of day.

01:03:44Flip it one way

01:03:45and it's the

01:03:45daytime driving mode.

01:03:47Flip the other

01:03:48and you're ready

01:03:49to drive safely

01:03:49during nighttime

01:03:50as it tones down

01:03:51the glare coming

01:03:52from headlights

01:03:53of the cars

01:03:54behind you.

01:03:55Next time you head

01:03:56out to the supermarket,

01:03:57make sure to keep

01:03:58this in mind.

01:03:59In case you don't

01:04:00have a coin

01:04:00to unlock

01:04:01these shopping carts,

01:04:02there is a well-kept

01:04:03secret that can

01:04:04help you out.

01:04:05If you have

01:04:06your house keys

01:04:06on you,

01:04:07check for a

01:04:08rounded key head.

01:04:09If you happen

01:04:10to find one,

01:04:11try using it

01:04:11to unlock the cart.

01:04:13It should fit

01:04:13perfectly in there,

01:04:15replacing the need

01:04:15to carry coins around.

01:04:17Because,

01:04:17if we're being honest,

01:04:18who still has them?

01:04:21Elevators.

01:04:21If you want to ride

01:04:22them on your terms

01:04:23and your terms only,

01:04:24make sure to try

01:04:25something out.

01:04:26Most elevators

01:04:27have a secret

01:04:28button combination

01:04:29you can use

01:04:30to skip all

01:04:30the other selected floors

01:04:32and go directly

01:04:33to the one

01:04:33of your choosing.

01:04:34This might work out,

01:04:36especially on those

01:04:37days when you've

01:04:37pressed 13.

01:04:38But you wanted

01:04:39to press 33.

01:04:41On most elevators,

01:04:42this works once

01:04:43you simultaneously

01:04:44press the

01:04:45closed door button

01:04:45together with

01:04:46your floor number.

01:04:47This should help

01:04:48you get to your

01:04:49floor without stopping.

01:04:50Some elevators

01:04:52require you to

01:04:52double-press the

01:04:53selected floor numbers,

01:04:54as double-pressing

01:04:55will often cancel

01:04:57the previously

01:04:57made request.

01:04:58While other elevators

01:05:00require you to

01:05:01hold the open door

01:05:02button and then

01:05:03double-press the

01:05:04buttons of the

01:05:04floors you'd like

01:05:05to cancel.

01:05:06Now, to stay

01:05:07out of trouble,

01:05:08it's best not to

01:05:09cancel the floors

01:05:09of the other

01:05:10people in the

01:05:11elevator.

01:05:11They won't

01:05:12take it kindly.

01:05:13Also, keep in

01:05:14mind that there

01:05:14are elevators

01:05:15that might not

01:05:16have this function.

01:05:17Now, for honey

01:05:18lovers out there,

01:05:19go ahead and

01:05:20raise your hand.

01:05:20If your pot of

01:05:22golden honey is

01:05:23crystallized,

01:05:23know that it is

01:05:24actually a good

01:05:26sign.

01:05:27Crystallized honey

01:05:27means that it

01:05:28hasn't been

01:05:29pasteurized,

01:05:30which means

01:05:30better product

01:05:31quality.

01:05:32With a decrease

01:05:33in temperature,

01:05:34the natural

01:05:34ingredient of

01:05:35honey, also

01:05:36known as

01:05:36glucose, will

01:05:37make it

01:05:38crystallize.

01:05:39Now, try

01:05:40making the

01:05:40best of it.

01:05:41To add some

01:05:41texture to your

01:05:42oatmeal or toast,

01:05:43add a layer of

01:05:44crystallized honey

01:05:45and enjoy nature's

01:05:47sugar.

01:05:47And if you don't

01:05:48like crystallized

01:05:49honey, plop it in

01:05:50the microwave for a

01:05:51minute or two.

01:05:52Ah, winter and

01:05:53fall.

01:05:54You know what

01:05:54this means, right?

01:05:56Sweater weather.

01:05:57But there's

01:05:57nothing more

01:05:58annoying than

01:05:59wearing your

01:05:59beautiful wool

01:06:00sweater and

01:06:01itching yourself

01:06:02all the way

01:06:03through it.

01:06:04Actually, I can

01:06:05be more annoying

01:06:05than that, but

01:06:06let's talk about

01:06:07itchy sweaters.

01:06:08To keep this from

01:06:09happening again,

01:06:10here's the secret.

01:06:11Turn your

01:06:11sweater inside out

01:06:13and soak it in

01:06:13cold water.

01:06:14Add two or three

01:06:15tablespoons of

01:06:16vinegar and let it

01:06:17sit for a while.

01:06:18Then, drain the

01:06:19water.

01:06:20Now, while the

01:06:21sweater is still

01:06:22wet, massage a

01:06:23generous amount of

01:06:24hair conditioner into

01:06:25the fibers of the

01:06:26wool.

01:06:27After letting it

01:06:28soak in the hair

01:06:28conditioner for about

01:06:2930 minutes, gently

01:06:31press the excess water

01:06:32out of the wool and

01:06:34leave it to dry flat on

01:06:35a towel.

01:06:36There you go!

01:06:37No more itchy

01:06:38sweater.

01:06:39Any fast food

01:06:40restaurant you go to

01:06:41will hand out small

01:06:42paper cups for

01:06:43customers to fill with

01:06:44their ketchup, mustard,

01:06:45or barbecue sauce.

01:06:47But if you're eating

01:06:48some chicken nuggets or

01:06:49trying to dip your

01:06:50burger into the cup,

01:06:51there's always that

01:06:52bit of sauce that

01:06:53seems impossible to

01:06:54reach.

01:06:55Next time, try

01:06:56unfolding the cup.

01:06:58It'll turn into a

01:06:59small paper plate, and

01:07:00this way, you'll get

01:07:01all the ketchup you

01:07:03poured in the first

01:07:03place.

01:07:05Padlocks used in

01:07:06outdoor environments

01:07:07should be clean and

01:07:08lubricated every

01:07:09three months.

01:07:10Regular lubrication

01:07:12will help prevent

01:07:12padlocks from

01:07:13freezing in cold

01:07:14weather conditions.

01:07:15Look for the tiny

01:07:16hole on the bottom

01:07:17of the lock.

01:07:18Then, pour oil into

01:07:20it, and there you

01:07:21go!

01:07:21It opens again!

01:07:23One thing we often

01:07:24neglect is a point in

01:07:26an ointment cap.

01:07:27These pointy surfaces

01:07:28were designed to help

01:07:29us break the tinfoil

01:07:30protection of the

01:07:31ointment tube.

01:07:32You just turn the cap

01:07:34over and break the

01:07:35ointment seal with its

01:07:36own cap, and there

01:07:38you go!

01:07:39After a long day of

01:07:40work, all you really

01:07:41need to do is a bubble

01:07:42bath.

01:07:43You turn on the hot

01:07:44water and let it run

01:07:45for a few minutes.

01:07:46You might even light a

01:07:47candle and pour some

01:07:48essential oils into

01:07:50the water.

01:07:50Then, in comes the

01:07:52liquid soap.

01:07:53You stir the water

01:07:54until the entire

01:07:55surface of the tub

01:07:56water is crammed with

01:07:57bubbles and make your

01:07:59way in.

01:08:00The bubbles in a

01:08:01bubble bath have a

01:08:01fundamental primary

01:08:03function.

01:08:03Their job is to

01:08:04preserve the water's

01:08:05temperature, just so

01:08:07you can have warm

01:08:08water for longer.

01:08:09Do you have sweaty

01:08:10feet?

01:08:11Weird question, I know.

01:08:12But if you're one of

01:08:13these people, here's

01:08:14some good news.

01:08:16All is not lost.

01:08:17Try putting a dry

01:08:18tea bag inside your

01:08:20shoes and storing it

01:08:21in a dry place for a

01:08:22while.

01:08:23The tea bags will

01:08:24absorb the humidity

01:08:25and the smell off the

01:08:27soles of your shoes.

01:08:28So, here I am

01:08:29thinking, shouldn't we

01:08:30have learned these

01:08:31things in school?

01:08:32Well, either way, if

01:08:34you learned something

01:08:34new today, make sure

01:08:35to tell us about it in

01:08:36the comments below.
