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.
00:01:36Another little thingy we often neglect is a point on an ointment cap.
00:01:41Most 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.
00:02:34And after the flight, the words of the passengers work ideally instead of cameras.
00:02:39So, if cameras do no good, then why spend money on them?
00:02:43Water is great at cleaning stuff because it has triangular molecules.
00:02:46They'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, the 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.
00:03:42These metals 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.
00:04:43You 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.
00:05:36The 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.
00:06:03They 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.
00:07:05This 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.
00:07:48Green 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.
00:08:00Two 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 bed sheets.
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.
00:08:30It's like proof that you've checked into a clean room.
00:08:34If you look at it on the street, you'll think a fire hydrant is about 3 feet in height.
00:08:39But the actual size of the device used to provide water supply to firefighters all over the world is twice
00:08:44as large.
00:08:45That is, if you count the rest of the hydrant, which is hiding underground.
00:08:49They're mostly red and it's not just a matter of urban design.
00:08:52First of all, they need to be of bright, easily noticeable colors so firefighters can spot them fast when they
00:08:58need to.
00:08:58The choice of color depends on how much water the hydrant can hold.
00:09:02It can sometimes vary depending on the location, but here's the breakdown.
00:09:06A red fire hydrant can splash 500 gallons of water per minute, while an orange one at least 1,000
00:09:14gallons.
00:09:15Green ones mostly process 1,500 gallons of water per minute, and the most plentiful ones colored blue can generally
00:09:22contain over 1,500 gallons.
00:09:25Hey bowling fans, isn't it super annoying when your bowling ball gets cracked?
00:09:29Turns out that most of them get damaged because of incorrect storage or spikes in temperature.
00:09:35Now come on and face it, since it's already cracked a bit, aren't you curious what's actually inside the bowling
00:09:40ball?
00:09:41Because I sure am.
00:09:42Let's have a look.
00:09:43They mostly make the inner core of the ball of powdered metal oxides, like calcium or iron oxide.
00:09:49They mix them with some resin and catalyst to harden the whole mixture.
00:09:53So, that light bulb shape you now see inside of the ball is actually its heaviest part.
00:09:58It also influences how your bowling ball rotates when going down the lane.
00:10:03The same goes with spray paint cans.
00:10:05When you shake it, it makes a weird noise, but what is that thing in there?
00:10:09It's called a pea, and it's meant to hold the paint mixture in place and maintain its shape.
00:10:14They generally make it out of plastic, metal, or ceramic.
00:10:17It basically acts as a whisk to make sure your paint is well mixed together before you apply it to
00:10:23your surface of choice.
00:10:25Ever wondered how soda bottles keep that refreshing fizz for that long?
00:10:29Well, they have a little plastic ring fastened to the lid.
00:10:32They place it there to keep the gas from escaping and making the soda go flat, even if you shake
00:10:38it around in your bag the whole day.
00:10:41Speaking of things we use on a hot summer's day, wait, wait, don't put your baseball cap on just yet.
00:10:46Take a look at it for a minute, and you'll notice there's a small button on the very top.
00:10:51Is it functional, or is it just there for the sake of design?
00:10:54Way back when people started using fabrics to cover their heads, some say the button was actually functional.
00:10:59Since it's on top of the cap where the fabric panels come together, the top button helps keep the cap
00:11:05crown in one single piece.
00:11:07Now, with recent advances in fabric and pattern design, the button is more of an aesthetic feature.
00:11:13It's used to cover up the joint point of the fabric panels.
00:11:16Your cap might not have a button at all, but don't you think a cap actually looks better with one?
00:11:22Cotton pads have two sides, and if you take the time to look at them carefully, they're actually different in
00:11:27texture.
00:11:27Just in case you've ever wondered why, the textured side is for applying makeup, and the even side is for
00:11:34removing it.
00:11:36Bookworms, this one is for you.
00:11:38Dust jackets that come with a lot of hardcover books are not just meant to make your book look pretty,
00:11:43they also double as a bookmark.
00:11:45Just fold the pages you've already read underneath the inside of the jacket, and voila!
00:11:50Next time you reach out for your favorite shirt, take a look at the top buttonhole.
00:11:54It should be stitched horizontally, and all the other ones are vertical.
00:11:59Turns out that the dress shirt was designed this way, since the first and the last buttons were the first
00:12:04ones to unbutton throughout the day.
00:12:06They then changed the direction of the buttonhole to ensure the shirt would stay nice and fitted before you're ready
00:12:11to take it off.
00:12:14These days we have so many variations of this awesome dessert, that it's hard to imagine we've ever lived without
00:12:19it.
00:12:19You can find different types of cookie dough ice cream or even chocolate chip cookie cake basically everywhere, but the
00:12:26famous cookie wasn't actually invented until 1930.
00:12:29The story goes that a woman named Ruth Graves Wakefield was preparing some chocolate cookies as she was waiting for
00:12:35some guests to arrive.
00:12:36She soon figured out she was out of baker's chocolate, a crucial ingredient for the classic cookies.
00:12:42To fix things up, she chopped up a block of semi-sweet chocolate, thinking it would eventually spread out evenly
00:12:47throughout the batter, given the heat of the oven.
00:12:50Things didn't necessarily go as planned.
00:12:52But hey, it's great they didn't, because this is how she invented this modern dessert we now can't get enough
00:12:58of.
00:12:59And speaking of popular snacks, the potato chip is even younger than the chocolate chip cookie.
00:13:05Well, at least historically.
00:13:07There are many stories trying to explain how it was invented.
00:13:10One of them goes like this.
00:13:12A chef named George Crumb, based in New York, put the chips together in 1953.
00:13:18He decided to try a different cooking solution when one of his customers didn't have nice things to say about
00:13:23his french fries.
00:13:24He said they were too thick and kind of mushy.
00:13:27Then, Crumb came up with potatoes that were thinly sliced and fried until brown.
00:13:32People absolutely loved the dish.
00:13:35And they welcomed the first ever batch of chips with open arms.
00:13:40Ice cream, anyone?
00:13:41If the story is true, back in 1904 at the St. Louis World's Fair, one ice cream shop owner ran
00:13:47out of cups to serve his dish.
00:13:49So, he fashioned a waffle into the shape of a cone.
00:13:52And the rest was history.
00:13:54Okay, I'll admit it, chewing gum-like treats have been around since the ancient Greeks.
00:13:59So, this one isn't particularly a revolutionary discovery.
00:14:02But the actual gum we buy today wasn't there until the late 1800s.
00:14:07An American inventor named Thomas Adams wanted to mix together different chemicals to create rubber.
00:14:13He tried and failed, for that matter, to play with Chickle for his experiment, but ended up fashioning this neat
00:14:19treat.
00:14:19They still use Chickle to this day to produce most chewing gums.
00:14:24Back in the 1800s, there lived a man named Jean-Baptiste Jolly, who worked in the fabric industry as a
00:14:29textile maker.
00:14:31How he came up with this next invention that we use a lot these days has less to do with
00:14:35him and more to do with his maid.
00:14:38The story goes that the woman accidentally knocked a kerosene lamp over onto a tablecloth.
00:14:43Instead of getting upset over the damaged fabric, Jolly noticed that the substance actually made the material cleaner.
00:14:50Figured it out yet?
00:14:52Yep, that's how the idea for the very first dry cleaner popped up.
00:14:55A very neat accident, if I do say so myself.
00:15:00Now this one I loved.
00:15:01Did you know matchsticks were initially called friction lights?
00:15:05Or at least that's how their inventor, a chemist, named John Walker, called them back in 1826.
00:15:11He scraped a stick coated in chemicals across his hearth, totally by accident one day, and realized that they ignited
00:15:18and created a spark.
00:15:20Initially made out of cardboard, they were then made using wooden splints and sandpaper.
00:15:27Back in the 1940s, a man named Harry Coover stumbled upon a chemical formulation that seemed to stick to everything
00:15:33it touched.
00:15:34The scientific community at the time didn't look much into it, as the formula didn't seem to have many applications
00:15:40back then.
00:15:41It wasn't until 1951 that he looked a bit more into the formula and decided to repurpose it,
00:15:47along with a fellow Eastman Kodak researcher named Fred Joyner.
00:15:51They gave it a proper full name.
00:15:53But you must know it by the shorter version.
00:15:56Superglue.
00:15:58It also has many uses in security these days that it's hard to believe that we didn't come up with
00:16:03this one on purpose.
00:16:05Back in 1903, a scientist named Edward Benedictus knocked over a flask by accident.
00:16:11He looked down and was amazed to see that the glassware had just slightly cracked but maintained its shape.
00:16:17He was expecting it to break into a million tiny pieces.
00:16:21Curious about this hidden feature, he looked into it and figured out what was keeping the glass together was a
00:16:26substance coating the inside of the glass.
00:16:29Ta-da!
00:16:29That's how humanity came up with safety glass.
00:16:35So get this.
00:16:36An extra hole at the upper part of the sink has multiple hidden functions.
00:16:40First, in case someone forgets to close the tap, the water won't overflow and the bathroom won't get flooded.
00:16:46Second, thanks to that hole, the water drains faster and it gives an escape for the air, helping the water
00:16:52flow down.
00:16:54Those two holes on a side of any Converse shoe are not only to let the stinky air out.
00:16:59Sure, breathability is important for any athlete.
00:17:02The second reason is that athletes lace through those holes to get a better grip.
00:17:08Donuts have a hole in the middle and it doesn't stand for O in donut.
00:17:12It's not designed for an easier grip either, though it can be quite convenient.
00:17:17It's actually made this way for mass baking, so that they can cook all the way through evenly.
00:17:23Baby carrots are tiny and, unlike regular carrots, wet.
00:17:27Baby carrots aren't some special sort of carrots.
00:17:30They're actually made of regular carrots by cutting off the skin and outer layers and then polishing them to look
00:17:36that pretty.
00:17:37The problem is that they can't retain moisture.
00:17:39A regular carrot retains some water inside because of the layers that locks it in.
00:17:44Once they're chopped out, baby carrots can dry out easily, so they usually sell them in bags with some water
00:17:49inside.
00:17:51Toy stores are filled with Beanie Baby plush toys.
00:17:54And a detail that is even more iconic than their huge eyes is their tags, saying TY.
00:18:00That's a small manufacturing company not so many people have heard of.
00:18:04Beanie Babies appeared in 1993 and they went insanely popular.
00:18:08TY is the name of the company, but it's not an abbreviation.
00:18:12It's the actual name of the company's founder, H. Ty Warner.
00:18:17Most metallic zippers have a hidden lock inside them to save you from awkward situations, such as an undone fly.
00:18:24Oh boy.
00:18:26Don't leave the zipper handle in an upward position.
00:18:28When you pull it downwards, it automatically locks.
00:18:31It's all thanks to those tiny grooves hidden underneath the handle.
00:18:37Almost any public toilet has a large gap between the floor and the door.
00:18:41The reason for such a zero-privacy thing is to actually minimize the level of privacy and comfort,
00:18:47so that people wouldn't stay there long and there'd be no lines.
00:18:49It's also easier to clean, and safer if some emergency occurs.
00:18:57Headrests in a car are about comfort, and detachable headrests are about safety.
00:19:01If you pull the headrest out of a seat, you'll see two bars, which are quite sturdy.
00:19:07If you ever get locked or trapped in a car, you can get out of there smashing the window with
00:19:11these bars.
00:19:15Many cups and mugs have little grooves on the bottom on purpose.
00:19:19They're designed for dishwashing machines.
00:19:21The grooves let the water flow and not spill over your feet when you take the cup out.
00:19:25Also, those grooves let the air flow, so the cup doesn't crack even if the tea is scalding.
00:19:33Almost all measuring tapes have a metal tip with a small slot on the end.
00:19:37You can use this slot to hang the tape on a nail or a screw to make measurements without anyone's
00:19:43help.
00:19:44Sometimes, this tip has a row of sharp points along the edge on one side.
00:19:48That comes in handy when you want to leave a mark without using a pencil.
00:19:54Doorknobs are usually made of brass, bronze, and some other copper alloys for a reason.
00:19:59They have an antibacterial effect, so they stop microbes from spreading.
00:20:04They get rid of a range of harmful germs pretty fast, within a couple of hours.
00:20:08But don't forget to wash your hands anyway.
00:20:12Grocery carts have loops for a reason.
00:20:15You don't want to put your jacket in a cart next to potatoes and onions.
00:20:18Hang it on a loop.
00:20:20This little hook-like thing is there to help you better organize the space in your cart.
00:20:25The carts also have a super handy grid.
00:20:28Whenever the cart's full, you just need to lift the grid and attach the shopping basket for extra purchases.
00:20:33Placing it in between the horizontal bar above the wheels and the hooks the grid has.
00:20:40A point in an ointment cap is there for a reason too.
00:20:44Most tubes are usually sealed with foil, and it's better to avoid opening it with fingers unless you're ready to
00:20:49say goodbye to your nails.
00:20:51A point easily opens even the most safely sealed tube.
00:20:56Silica gel can often be found in different things you buy, like bags, shoes, and many others.
00:21:02Don't throw it away.
00:21:03It's meant to absorb excess moisture.
00:21:05So anytime your shoes are a bit wet, just throw in a packet with silica gel.
00:21:11People used to co-live with rats, and these guys like gnawing on everything they see in their way, including
00:21:17paper.
00:21:19Still, rats weren't able to chew more than the space left on the margins.
00:21:25That black grate on a microwave isn't just some fancy decoration.
00:21:29It's called a Faraday shield, and it prevents the rays from escaping the microwave.
00:21:33It also speeds up the heating, so you can enjoy yesterday's leftovers faster.
00:21:38It may also block phone signals.
00:21:40So if you're tired of numerous calls, just put the phone into a microwave.
00:21:44But don't turn it on.
00:21:49All Tic Tac containers are designed to dispense one Tic Tac every time you open it.
00:21:54The lid has the same shape as the candy.
00:21:56Turn the container upside down, gently shake it, and open it slowly.
00:22:00You'll notice only one candy stuck between those lid grooves.
00:22:03So if you just open the container and shake it until five or even more candies fall into your mouth,
00:22:08it means you've been eating Tic Tacs wrong all this time.
00:22:16Those little holes in the airplane windows are designed to control the cabin pressure.
00:22:20They also protect the windows from fogging up as the temperatures drop and rise.
00:22:24By the way, the airplane window is round for a reason.
00:22:27This way, pressure is evenly distributed so it doesn't get deformed.
00:22:33Blue bristles on a toothbrush are actually an indicator that it's just about time to change the brush.
00:22:38As the bristles get in contact with water, the blue, or whatever other, pigment fades away.
00:22:44So the more you use it, the duller the color becomes.
00:22:49A triple handle on a jerry can is there to make it easier for two people to carry it and
00:22:53distribute the fuel evenly.
00:22:54Gas cans often have a second hole that actually needs to be uncapped too before you pour the gas.
00:22:59The air passage will prevent it from pouring out, so no more fuel waste.
00:23:06Jeans first appeared in 1873.
00:23:09They were invented by Jacob Davis and Levi Strauss.
00:23:13Davis was a tailor who was producing covers and tents,
00:23:16and Strauss was a businessman who, among other things, was selling cloth.
00:23:21The first jeans were made by Davis from denim, the fabric he bought from Levi Strauss and co.
00:23:27Together, they patented the design.
00:23:29Blue was a standard color for denim that was dyed using an indigo dye.
00:23:34The blue color is a tradition that is still often followed today to replicate the original look of a pair
00:23:39of jeans.
00:23:40Jeans also have metal rivets, and they've been there from the very beginning.
00:23:44Jacob Davis, the man who made the first pair of jeans,
00:23:47added copper rivets to spots where pants were more likely to rip,
00:23:51flies and pockets to make them stronger.
00:23:53Today, they have more of a decorative purpose since they're distinctive and traditional for jeans.
00:24:01Another special thing about jeans is those tiny pockets they have that seemingly serve no purpose.
00:24:06Well, maybe it's true now, but years ago, when many cowboys were wearing jeans,
00:24:10the pocket was made specifically to keep a pocket watch there.
00:24:14Also, back then, a pair of jeans had just four pockets.
00:24:18That tiny pocket, the watch pocket, two big pockets in front, and just one pocket on the back.
00:24:25Many zippers have the letters YKK engraved on them.
00:24:29It's an abbreviation that stands for the name of the company that can be translated as
00:24:34Yoshida Manufacturing Shareholding Company.
00:24:37This Japanese company is the largest zipper manufacturer in the world,
00:24:41so they put their initials on all the zippers they produce.
00:24:44That's around half of the zippers in the world.
00:24:47And that's why you see their zippers more often than any other zippers.
00:24:52Those little white golf balls have dimples all over them.
00:24:55It turns out they aren't there just randomly.
00:24:57At first, golfers were playing with a smooth ball.
00:25:00With time, the ball would get all punched and damaged,
00:25:03but also, it would start to travel way further.
00:25:06The reason here is aerodynamics.
00:25:09Dimples allow the air to flow more smoothly around the ball, taking it further.
00:25:13So the idea was adopted, and the balls got their dimples all around,
00:25:17allowing them to travel longer distances.
00:25:21For all those days when you barely have time for breakfast,
00:25:24there's an easy way to enjoy a nice and fast meal.
00:25:27And it will also save you the hassle of doing the dishes afterwards.
00:25:31I'm talking about instant oatmeal packets.
00:25:34Some manufacturers have added this neat design to the oatmeal.
00:25:38The packet is lined with plastic,
00:25:40so you can directly pour water or milk straight into it.
00:25:44This way, you won't have to use a bowl anymore.
00:25:47You place the liquid in and shake.
00:25:50Some packaging also has a demarcation line
00:25:52to show how much liquid should go inside the pack for that quantity.
00:25:57Next time you have to switch apartments,
00:26:00you won't have to worry about carrying that heavy box of books.
00:26:03These days, most moving boxes are specially designed for easy transportation,
00:26:07with built-in handles.
00:26:09Well, they're not actually handled.
00:26:11I'll admit, they're basically just holes inside the cardboard box, on the sides.
00:26:17But if you slip your hands in,
00:26:19you'll surely notice the boxes become way easier to carry
00:26:21than picking them up altogether.
00:26:25With the onset of so many online reading options,
00:26:28like e-books or even apps on your phone
00:26:30that allow you to download novels,
00:26:32you've most likely forgotten about your local library.
00:26:36And hey, I'm not blaming you!
00:26:38But libraries these days offer a lot more services than you're used to,
00:26:42apart from free books and audiobook rental.
00:26:45Some of them have a variety of evening classes
00:26:48or can provide access to online courses.
00:26:52You may even be able to join a book club,
00:26:54which is a great way to meet new people,
00:26:56and you're guaranteed to get out of that reading slump you've been stuck in.
00:27:01I enjoy picking up dinner on my way home
00:27:03from my favorite takeout place, just as you do.
00:27:05But if the food containers are not completely sealed shut,
00:27:09the ride back can prove itself quite the culinary experience,
00:27:12if you know what I mean.
00:27:14Especially for the carpets in your car.
00:27:17Some cars have a curry hook near the center console,
00:27:20next to the driver's seat.
00:27:22It has been popular for 20 years
00:27:24and started as a handbag holder or a hook for a small shopping bag.
00:27:28But it quickly became the perfect way to store takeaway food and avoid spilling.
00:27:34I'm almost sure there's an umbrella somewhere in your car,
00:27:37but if I were to ask you where you're storing it,
00:27:39you'd most likely say,
00:27:40the truck, of course.
00:27:42But is that really the best place to keep it?
00:27:45Wouldn't you want to have an umbrella at hand,
00:27:47right when you get out of the car?
00:27:50Some car companies have thought about that,
00:27:52and don't worry,
00:27:53they don't come with a built-in butler
00:27:54to help you get out of the car all dry.
00:27:57Some specific models have a designated place
00:28:00in the driver's door panel
00:28:01that perfectly fits an umbrella.
00:28:03You have to admit,
00:28:04it's an important thing to consider
00:28:05when researching your next car,
00:28:07more so if you live in a rainy location.
00:28:11Whenever I plan to travel to a new location,
00:28:13I like to have access to the local maps on my phone
00:28:16at any given time.
00:28:17Since you can't always foresee the quality
00:28:20or price of the internet in foreign countries,
00:28:22be sure to download the maps on your phone
00:28:24when connected to Wi-Fi.
00:28:26This way, you'll have easy access
00:28:28to all the must-see locations on your next city break,
00:28:32even if you run out of mobile data.
00:28:34The same goes for Google Translate.
00:28:37The mobile app comes with the option
00:28:39of downloading a language
00:28:40so you'll be able to use it offline.
00:28:43Another nice tip
00:28:44if you're more of the traveler type.
00:28:46If you own an iPhone,
00:28:47text an airline code
00:28:49and flight number to yourself.
00:28:50You'll then notice
00:28:51it will show up with an underline.
00:28:53When clicking on it,
00:28:54you'll be able to pull up flight data,
00:28:56like the gate the flight leaves from
00:28:57or if the flight is on schedule.
00:29:02Flashlights are those objects
00:29:03that we tend to reach out for in an emergency,
00:29:05like whenever there's a power break
00:29:07or when you need to take a quick trip in the attic
00:29:09for an old photo album or something.
00:29:12If you're ever in a sticky situation
00:29:14and the flashlight runs out of battery,
00:29:15have a look at its base under the battery spring.
00:29:18Some models come with a spare bulb hidden in there.
00:29:23If you're the type of person
00:29:25that likes to wake up early in the morning
00:29:26but the rest of the people in your house
00:29:28enjoy sleeping in,
00:29:29there's a way you can still use your microwave
00:29:31to prepare breakfast
00:29:32without waking everyone up.
00:29:34It turns out,
00:29:35some of them come with a built-in mute function
00:29:38that gets rid of all the annoying rings and beeps.
00:29:42In the many times I've found myself driving
00:29:45on local roadways,
00:29:46I've noticed some apparently random blue reflectors
00:29:48here and there.
00:29:50Since I had no idea what they were,
00:29:52I did some research
00:29:53and found out they actually pinpoint
00:29:54the locations of fire hydrants.
00:29:57They're generally offset from the center line
00:29:59on either side
00:30:00and the offset side
00:30:01tells if the hydrant is on the left
00:30:03or right side of the road
00:30:05to assist firefighters on their missions better.
00:30:09Next time you get out of the car
00:30:10and forget to close all the windows,
00:30:12you won't have to get back in there.
00:30:14Just try this.
00:30:15Hold the keys on the door of your car pressed
00:30:18and it should lock all the doors
00:30:19and shut all the windows.
00:30:21The same goes with opening all the doors.
00:30:24Just double-click the button.
00:30:26Most car models should come with this added option,
00:30:29but most people just forget
00:30:30or have no idea that they can do that.
00:30:34Whenever you're in that awkward position
00:30:36of messing up a voicemail,
00:30:37do you know there's a way you can delete
00:30:39or re-record the message,
00:30:41saving you the unnecessary embarrassment?
00:30:44Stay online after recording the message
00:30:46and dial either pound, number sign,
00:30:48or star, asterisk,
00:30:50to access the voicemail menu.
00:30:52Further instructions should be provided
00:30:54so you can decide what to do with the recording.
00:30:58Bagels are becoming more and more famous these days
00:31:01on options for breakfast or snacks
00:31:03because they're so tasty and so versatile.
00:31:05The problem is,
00:31:07I only want my bagel toasted on one side.
00:31:10Thankfully, some toasters come with a bagel setting,
00:31:13which ensures the pastry is toasted
00:31:15on either one of the two sides.
00:31:19Ever wondered why manhole covers
00:31:21only come in that round shape?
00:31:23It turns out that this is the only shape
00:31:25that cannot fall through the hole altogether.
00:31:27Any other shape,
00:31:28especially shapes with corners,
00:31:30could be rotated so that the lid could fall through.
00:31:34Here's a neat one if you enjoy a little massage
00:31:37whenever you're taking a shower.
00:31:38On most of the shower heads available these days,
00:31:41there should be a small metal filter in the back
00:31:44beneath the shower head once you unscrew it.
00:31:47If you give this piece a rough cleaning once in a while,
00:31:50you'll find the water pressure to be greatly improved.
00:31:54You may be able to save that wool sweater
00:31:56you've accidentally thrown in the washer
00:31:58and has shrunken down three sizes.
00:32:00Just go in the shower and grab a bottle of hair conditioner.
00:32:04Add it to some cold water in a tub
00:32:06and make a solution
00:32:07and let the garment sit there
00:32:08for at least a couple of hours.
00:32:11The conditioner should help relax the wool fibers
00:32:13and loosen them back up,
00:32:15not to mention how nice it should smell afterwards.
00:32:20You might need to do a bit of research
00:32:22before you can safely use this trick.
00:32:24But just so that you know,
00:32:26there are some modern laptops with drainage channels.
00:32:29Mm-hmm, you heard that right.
00:32:31Precisely when you accidentally spilled coffee on it,
00:32:33they're designed to ensure any liquid that gets on the keyboard
00:32:36safely drains out at the bottom
00:32:38without damaging the electrical parts.
00:32:40Just make sure to not shake the laptop
00:32:42after you've spilled the liquid
00:32:44so that the system can do its job correctly.
00:32:52You got used to browsing the web,
00:32:54playing games,
00:32:55and connecting with your friends on social media,
00:32:57all at the convenience of the iPhone in your pocket.
00:33:00But what if I were to tell you
00:33:02that there were many more hidden uses inside it?
00:33:06Back Tap
00:33:08Have you ever noticed that fancy Apple logo
00:33:10on the back of your iPhone?
00:33:12If you've got a cover on,
00:33:14go ahead and pull it off
00:33:15so you can check it out.
00:33:17Okay, you're now probably thinking,
00:33:19there's nothing secret about this,
00:33:21the obvious brand logo on my iPhone.
00:33:24Sure, it might not seem so special,
00:33:27but did you know
00:33:28that it's more than just a handsome decoration?
00:33:30It's also, as a matter of fact,
00:33:33a button.
00:33:34Don't believe me?
00:33:35Give it a try.
00:33:38But, before you go tapping at it
00:33:40like you're using your phone backward,
00:33:42you'll need to adjust your settings.
00:33:44There's a reason this handy feature
00:33:46is considered a secret.
00:33:47First, pull up your settings.
00:33:49Tap on Accessibility,
00:33:51and then the Touch menu,
00:33:53and navigate your way
00:33:54to the very bottom of the list,
00:33:56where you'll find the Back Tap button.
00:33:59Found it?
00:34:00Great!
00:34:01You can choose the Double Tap
00:34:03or Triple Tap option,
00:34:05whichever you prefer,
00:34:06and best of all,
00:34:08you'll have a multitude of options
00:34:10to choose from.
00:34:11You can have your Back Tap feature
00:34:13take a photo with your camera app,
00:34:15alert Siri,
00:34:16switch apps,
00:34:17and even take a screenshot.
00:34:19It'll make things a lot easier
00:34:21than performing finger gymnastics
00:34:23when you need to take a screenshot.
00:34:26Adjust Siri's pronunciations.
00:34:29Have you ever asked Siri to call a friend?
00:34:32Maybe you've said,
00:34:33Siri,
00:34:34call Hermione,
00:34:36only for Siri to comply with
00:34:38calling Hermione.
00:34:40Okay, you may not have
00:34:42Harry Potter's best friend
00:34:43in your contacts list,
00:34:44but we can all agree
00:34:46it's not the easiest name to pronounce.
00:34:49Siri might be one of the most
00:34:51intelligent digital assistants
00:34:52in the smartphone game,
00:34:54and sometimes a bit of a smarty pants.
00:34:57But iPhone's companion
00:34:59can often struggle to pronounce
00:35:00even the most common names.
00:35:03If this bothers you,
00:35:04then you'd be delighted to hear
00:35:05you can actually correct
00:35:07Siri's pronunciations.
00:35:09The simplest way
00:35:10is to catch Siri in the act
00:35:12and say,
00:35:13that's not how you pronounce.
00:35:15It will prompt Siri to ask
00:35:17for the correct pronunciation
00:35:18for each name,
00:35:20first, middle, and last,
00:35:22or the name of a place
00:35:23if it's not for a person.
00:35:25Once you've given it,
00:35:27Siri will generate some options,
00:35:28and all you have to do
00:35:30is pick the correct one.
00:35:32If your digital best friend
00:35:33is still struggling,
00:35:35it might help to spell it out.
00:35:37Open your contacts,
00:35:38select the person
00:35:39Siri is struggling to pronounce,
00:35:41and choose Edit.
00:35:43You can add the correct pronunciation
00:35:45in the Notes section
00:35:47using phonetic spelling
00:35:48and click Pronunciation Spelling
00:35:50to train Siri to get it right.
00:35:53Even a super smart digital assistant
00:35:55needs some help sometimes.
00:35:58Hey Siri,
00:35:58it's Leviosa,
00:36:00not Leviosar.
00:36:02Measure App
00:36:04Is a toolkit too clunky
00:36:06to carry around?
00:36:07Or maybe you've forgotten
00:36:08which drawer you placed
00:36:10the measuring tape in?
00:36:11That's okay.
00:36:12iPhone has got some more secrets
00:36:14that will help you out.
00:36:15Did you know that iPhone
00:36:17has a few tools in its arsenal
00:36:18that will serve your carpentry needs?
00:36:21Take the Measure App
00:36:22for instance.
00:36:23You no longer need that long,
00:36:25awkward-to-use floppy tape
00:36:26to get a measurement
00:36:27on your coffee table,
00:36:29bookshelf,
00:36:29or couch.
00:36:32The app uses augmented reality
00:36:34to measure objects around you
00:36:36using your phone's camera.
00:36:38The first thing you'll need to do
00:36:40is move your phone around
00:36:42so the app can analyze
00:36:43the area you intend to measure.
00:36:45You'll eventually find
00:36:47a white circle with a dot
00:36:48in the middle of your screen.
00:36:50From there,
00:36:51it's not so different
00:36:52from an actual measuring tape.
00:36:54Just line up the dot
00:36:55with the corner of the object
00:36:57you want to measure
00:36:58and trace it
00:36:59to where you want
00:37:00the measurement to end.
00:37:01If you're a builder,
00:37:03you might want to stick
00:37:04to the physical tape
00:37:05for more accurate measurement.
00:37:07This option isn't necessarily
00:37:08for the professionals.
00:37:10But the app is excellent
00:37:12for getting a rough estimate.
00:37:14The Measure app
00:37:15can also be used as a level.
00:37:18Simply switch over
00:37:19to the Level tab in your app
00:37:21and place your phone
00:37:22on the surface
00:37:23where you want to get a reading.
00:37:25When you get a green screen
00:37:27and a zero reading,
00:37:28your surface is nice and level.
00:37:31It's not so different
00:37:32from the Compass app's
00:37:33Level feature,
00:37:35so you might have had
00:37:36some bad experiences
00:37:37with this feature before.
00:37:38With your new digital toolbox,
00:37:41your iPhone will make you
00:37:42the handiest person
00:37:43in the house.
00:37:45Create custom vibration.
00:37:48We all live pretty fast-paced
00:37:50and busy lives these days.
00:37:52And whether we're at work,
00:37:54in a movie,
00:37:54or at school,
00:37:56more often than not,
00:37:57we have our iPhone
00:37:58set to vibrate.
00:38:01Sure, there are some
00:38:02cool ringtones to choose from.
00:38:04But there aren't many occasions
00:38:06where a sudden tune
00:38:07coming from our pocket
00:38:08wouldn't distract those around us.
00:38:10Or worse yet,
00:38:12it leads to our phone
00:38:13being confiscated
00:38:14by a disgruntled employer
00:38:15or teacher.
00:38:17Luckily,
00:38:18there are plenty of vibration options
00:38:20to choose from.
00:38:20You probably have various ones
00:38:22for different occasions
00:38:23and different contacts.
00:38:25None of those settings
00:38:26quite your jam?
00:38:27Apple has a solution to this too.
00:38:30Another hidden feature
00:38:31in the iPhone
00:38:32is creating a custom vibration
00:38:34for your alerts.
00:38:36If you want to feel the beat
00:38:37to your favorite song
00:38:38when your best friend calls
00:38:40or texts,
00:38:41or when it's time
00:38:42to wake up in the morning,
00:38:43you create that pattern
00:38:44on your iPhone.
00:38:46Once again,
00:38:47you'll need to go
00:38:48into those handy settings,
00:38:49then,
00:38:50in sound and haptics,
00:38:52choose the tone
00:38:52you'd like to customize.
00:38:54Tap vibration.
00:38:56Then,
00:38:57create new vibration.
00:38:58The next step
00:39:00is to create
00:39:00those sweet vibrations
00:39:02like a soundless DJ
00:39:03by tapping your finger
00:39:04on the screen
00:39:05until you have
00:39:06the silent rhythm
00:39:07you're happy with.
00:39:08Now you've got
00:39:09a vibrate option
00:39:10to your liking.
00:39:13It might even make
00:39:14the early morning
00:39:15wake-up calls
00:39:16just a little more pleasant.
00:39:17Just like the Beach Boys,
00:39:19you'll be picking up
00:39:20good vibrations.
00:39:23Trackpad.
00:39:25With smartphones,
00:39:26we no longer need
00:39:27two hands to use a keyboard.
00:39:29All you need
00:39:30is one good thumb.
00:39:32Yet,
00:39:33it can still prove
00:39:33a little tedious sometimes
00:39:35as typos are easy to make
00:39:37and all your characters
00:39:38can't fit all at once
00:39:39on that crammed keyboard
00:39:41at the bottom
00:39:41of your phone screen.
00:39:43You might be typing out
00:39:44a long body of text
00:39:45only to realize
00:39:47you left out the R
00:39:48out of the word drive
00:39:49a few sentences back,
00:39:51which might give your friends
00:39:52the wrong idea
00:39:53about what you're doing.
00:39:55It can be a fiddly task
00:39:56to fix it
00:39:57and it's often easiest
00:39:58to delete the entire word
00:40:00and write it all over again.
00:40:01Or,
00:40:02so it may seem.
00:40:03If you're a stickler
00:40:04for good grammar
00:40:05in your text messages,
00:40:07you might want to shift
00:40:08your keyboard
00:40:09into trackpad mode
00:40:10for easier editing.
00:40:11That's right,
00:40:12another hidden gem
00:40:13on your iPhone.
00:40:15It's easy to access too.
00:40:17All you have to do
00:40:18is hold your finger
00:40:19on the space bar.
00:40:20All the other keys
00:40:22will gray out
00:40:23and you'll be able
00:40:24to move the cursor
00:40:25to wherever it needs to go.
00:40:27Then,
00:40:27lift your finger
00:40:28off the space bar
00:40:29to continue typing.
00:40:31Another tedium
00:40:32to writing
00:40:32on that tiny iPhone keyboard
00:40:34is shifting tabs
00:40:35to use numbers
00:40:36and symbols.
00:40:37It may not seem like much,
00:40:39but it's sure
00:40:40to be a little frustrating
00:40:41when you have to jump
00:40:42back and forth
00:40:43multiple times
00:40:44in the same message.
00:40:45However,
00:40:46there is another hidden feature
00:40:48in your iPhone's keyboard
00:40:49that will alleviate this.
00:40:51Hold it down
00:40:52instead of tapping
00:40:53on the numeric 123 tab
00:40:55and it will bring up
00:40:57the numbers and symbols tab.
00:40:58As long as you're holding it,
00:41:00the tab will remain open
00:41:01to pick your character
00:41:03and releasing
00:41:03will return you to letters.
00:41:06Soon,
00:41:06you'll be fast enough
00:41:07to write a novel
00:41:08on your smartphone.
00:41:09Did you ever tie a string
00:41:11between two plastic cups
00:41:12so you could talk
00:41:13to your friend
00:41:14from opposite ends
00:41:15of your home?
00:41:15It may have seemed
00:41:16pretty cool at the time.
00:41:18But that plastic cup
00:41:19couldn't tell you
00:41:20the weather
00:41:20or let you send
00:41:21an email, right?
00:41:23Indeed,
00:41:24we've come a long way
00:41:24since the string telephone.
00:41:26In fact,
00:41:27can you even imagine
00:41:28life before smartphones?
00:41:30They have become
00:41:31almost like our clothes
00:41:32or the shoes we walk in.
00:41:34It's almost
00:41:35our consistent accessory.
00:41:36Now you know
00:41:37some of these handy secrets
00:41:39and you'll be an iPhone pro.
00:41:41However,
00:41:42if these secrets
00:41:42aren't for you,
00:41:43there's always
00:41:44the string telephone.
00:41:45At least it won't
00:41:46run out of charge.
00:41:50Have you ever
00:41:51stopped to think
00:41:52about the thrilling
00:41:53secrets of day-to-day
00:41:54modern life
00:41:55on planet Earth?
00:41:56I'm talking about
00:41:58tiny windows
00:41:58and washing machines
00:42:00and little holes
00:42:01in airplane windows.
00:42:02If you haven't got
00:42:04a clue of what
00:42:05I'm talking about,
00:42:06tag along
00:42:06and allow yourself
00:42:08to be as surprised
00:42:09as I was
00:42:10when I found out.
00:42:12Remember the drawer
00:42:13at the bottom
00:42:14of your oven?
00:42:15Maybe you've been
00:42:16ignoring it all along
00:42:17or using it to store
00:42:19pots and pans.
00:42:20Well,
00:42:20even though it can
00:42:21serve this function,
00:42:23that's not the only
00:42:24thing it's there for.
00:42:25The best way
00:42:26to use the bottom drawer
00:42:27is to keep your meal
00:42:28heated while you're
00:42:29waiting to serve it.
00:42:30Genius, right?
00:42:33Talking about secret doors,
00:42:35have you noticed
00:42:35that most washing machines
00:42:37have little flap doors
00:42:39at the bottom too?
00:42:40These doors actually
00:42:41serve as drain traps.
00:42:43It's where all the items
00:42:44that we put to wash together
00:42:46with our jeans
00:42:47and jackets go to.
00:42:49It's a type of collector,
00:42:50let's say,
00:42:51of small items.
00:42:52It stops them
00:42:54from getting into
00:42:54the main drain pipes
00:42:56and clogging them.
00:42:57It saves us
00:42:58hundreds of dollars
00:42:59in repairs each month.
00:43:01Now,
00:43:02who hasn't gone through
00:43:03the confusing task
00:43:05of having to measure
00:43:06how much pasta
00:43:07to cook
00:43:07for one serving?
00:43:09Well,
00:43:09here's the solution.
00:43:11The holes in the center
00:43:12of pasta spoons.
00:43:14They were actually made
00:43:15for measuring
00:43:16the exact amount
00:43:17of dry pasta
00:43:18you need for one serving.
00:43:20If you try stuffing
00:43:21wet cooked pasta through it,
00:43:23well,
00:43:24good luck with that.
00:43:26On a similar topic,
00:43:27have you ever wondered
00:43:28why pen caps
00:43:29have holes in them?
00:43:31Maybe you thought
00:43:32it was a design feature
00:43:33to regulate air pressure.
00:43:35But in reality,
00:43:36these holes have
00:43:37a much simpler
00:43:38and more important function
00:43:39to reduce the risk
00:43:41of choking.
00:43:42Now,
00:43:43lots of people
00:43:43love to bite
00:43:44on their caps.
00:43:45And this tiny hole
00:43:46prevents them
00:43:47from choking
00:43:48in case they
00:43:49accidentally swallow
00:43:50a cap
00:43:50and it gets stuck
00:43:51in their throat.
00:43:53For kitchen lovers,
00:43:54there's a hidden secret
00:43:55right in front of your eyes
00:43:57that can change
00:43:58your life.
00:43:59Think pans.
00:44:00Now,
00:44:01think handles.
00:44:02Right!
00:44:02They have holes in them.
00:44:04As it turns out,
00:44:05these holes were designed
00:44:07to hold the spoon
00:44:08you're using for cooking.
00:44:09And instead of dripping sauce
00:44:11all over the stove
00:44:12or your kitchen floor,
00:44:14you can place the spoon
00:44:15in the hole
00:44:16and let it drip the sauce
00:44:18directly back into the pan.
00:44:20Woo-hoo!
00:44:21Speaking of everyday items,
00:44:23and I was,
00:44:25most doorknobs
00:44:26are made of brass
00:44:27because this material
00:44:28makes them naturally germ-free.
00:44:31Unlike plastic ones,
00:44:33brass doorknobs
00:44:34are kind of magical.
00:44:35They can disinfect themselves
00:44:37without you having
00:44:38to clean them.
00:44:39Neat, right?
00:44:41Have you ever noticed
00:44:42that at the bottom
00:44:44of a measuring tape,
00:44:45there is a little dip?
00:44:46You can find it
00:44:48in that metallic part
00:44:49you need to pull on
00:44:50to measure something.
00:44:51Well,
00:44:52that dip
00:44:53is actually
00:44:53the exact size
00:44:55of a regular nail.
00:44:56It was designed
00:44:57for people
00:44:58to place the tape
00:44:59on top of a nail
00:45:00and use it as a support
00:45:01while they stretch the tape.
00:45:03Well,
00:45:03I can't wait
00:45:04to try it out
00:45:05for myself.
00:45:06As for the margins
00:45:08in your notebook,
00:45:09they were invented
00:45:10to protect people's notes
00:45:12from mice.
00:45:13No,
00:45:14the mice weren't
00:45:15copying your answers
00:45:16for the math quiz.
00:45:17Actually,
00:45:18there were times
00:45:19when people
00:45:20had to cohabitate
00:45:21with rats and mice
00:45:22that often chewed
00:45:24on paper.
00:45:25So,
00:45:25to prevent information
00:45:26from getting
00:45:27completely lost,
00:45:29people created margins.
00:45:30This way,
00:45:32texts were moved
00:45:32closer to the middle
00:45:34of pages
00:45:34and remained
00:45:35unharmed by rodents.
00:45:38Hmm,
00:45:38perhaps this is where
00:45:40to digest information
00:45:41came from.
00:45:43And what about
00:45:44those tiny holes
00:45:45at the bottom
00:45:46of airplane windows?
00:45:48They have an extremely
00:45:49important function
00:45:50of regulating
00:45:51the air pressure
00:45:52inside the cabin.
00:45:54In other words,
00:45:55they help planes
00:45:56fly high up
00:45:57in the sky.
00:45:58Big responsibility,
00:45:59right?
00:46:00By the way,
00:46:02tray tables
00:46:03on an airplane
00:46:03are the germiest
00:46:05places inside
00:46:06the entire cabin.
00:46:07Studies showed
00:46:08that the trays
00:46:09had eight times
00:46:11the amount of germs
00:46:12on the toilet flush button.
00:46:14Now,
00:46:15how about we cut
00:46:17a commercial airplane
00:46:18in half
00:46:18and see what's inside?
00:46:20Well,
00:46:21it would look
00:46:21more or less
00:46:22like this.
00:46:23Rows of seats
00:46:24on top
00:46:25and everything else
00:46:26that needs to be stored
00:46:27at the bottom.
00:46:28I'm talking about
00:46:29passengers' luggage,
00:46:31emergency supplies,
00:46:32parts of the wing system,
00:46:33and so on.
00:46:36Moving on
00:46:37to bowling balls.
00:46:38Yes,
00:46:38I know it's
00:46:39a clumsy transition.
00:46:41Anyway,
00:46:42have you ever wondered
00:46:43what the insides
00:46:45of a bowling ball
00:46:46look like?
00:46:46If you have cut
00:46:47a professional ball
00:46:49in two,
00:46:49you'll see
00:46:50a familiar shape.
00:46:51Look closely.
00:46:52Do you see it?
00:46:53Doesn't that look like
00:46:54the logo of Brightside?
00:46:56Anyway,
00:46:57professional bowling balls
00:46:59are different
00:46:59from the ones
00:47:00in your local bowling alley.
00:47:02That's because
00:47:03they're designed
00:47:03to make fancy moves.
00:47:05They actually have
00:47:06some really complex
00:47:07engineering inside.
00:47:09They're shaped
00:47:09to help skilled
00:47:10professionals
00:47:11get more strikes.
00:47:12The weight
00:47:13of professional
00:47:14bowling balls
00:47:14is designed
00:47:15to be projected
00:47:16inward
00:47:16as they travel
00:47:18down the bowling lane.
00:47:19This makes it
00:47:20harder for them
00:47:20to get into the gutters
00:47:22on the sides
00:47:22of the lane.
00:47:24Speaking of balls,
00:47:26let's take a look
00:47:27inside a baseball.
00:47:29To make it light
00:47:30and aerodynamic,
00:47:31producers use
00:47:32several different layers.
00:47:34Starting from the core,
00:47:35we have a cork center
00:47:37enveloped by black rubber.
00:47:39Then,
00:47:39there's a layer
00:47:40of red rubber
00:47:41followed by two
00:47:42or three alternating
00:47:43layers of wool yarn.
00:47:45After that,
00:47:46there's a visible
00:47:47white leather cover
00:47:48and that beautiful
00:47:50red seam on the side,
00:47:51stitching it all together.
00:47:54And,
00:47:55what if you had
00:47:56x-ray vision
00:47:57and managed to look
00:47:58inside a human bone?
00:47:59Ooh, spooky!
00:48:01I'd say
00:48:02what caused
00:48:03most attention
00:48:03is this spiderweb-like
00:48:05situation
00:48:06at the center
00:48:06of the bone.
00:48:07In reality,
00:48:08it's a highly condensed
00:48:10and complex
00:48:11structure of nerves
00:48:12that you have
00:48:13inside your bones.
00:48:14Aren't you lucky?
00:48:16Now,
00:48:17I've got a riddle
00:48:18for you.
00:48:19What is round
00:48:20can be found
00:48:21near the ocean
00:48:21and looks like
00:48:22an aerial view
00:48:23of the Guggenheim Museum
00:48:25in New York City,
00:48:26the one that's made
00:48:27almost entirely
00:48:28of ramps?
00:48:29If you said
00:48:30a nautilus shell,
00:48:31hey,
00:48:32then you guessed right.
00:48:33A nautilus
00:48:34is a shellfish
00:48:36whose house
00:48:36you can find
00:48:37in countless
00:48:38souvenir stores
00:48:39near the beach.
00:48:40It's made up
00:48:41of two layers,
00:48:42a matte white
00:48:43outer layer
00:48:44and an iridescent
00:48:45white inner layer.
00:48:46And,
00:48:47if you were to cut it
00:48:48in half,
00:48:49it would look
00:48:49very similar
00:48:50to the insides
00:48:51of the Guggenheim Museum.
00:48:53Aloe leaves
00:48:55are good
00:48:55for healing purposes
00:48:56and also
00:48:56for hydration.
00:48:58But,
00:48:59if you managed
00:49:00to look inside
00:49:01of an aloe leaf,
00:49:02the image you'd see
00:49:03would be satisfying
00:49:04and very relaxing.
00:49:06Who hasn't dreamed
00:49:08of a pool
00:49:08filled with jelly?
00:49:10Now,
00:49:11there seems to be
00:49:12nothing more mundane
00:49:13and regular
00:49:14than a tube
00:49:15of toothpaste.
00:49:16But you wouldn't
00:49:17think so
00:49:18if you cut open
00:49:19a tube
00:49:19that contains
00:49:20several colors.
00:49:21Now,
00:49:22there have been
00:49:22speculations
00:49:23that the insides
00:49:24of such a toothpaste
00:49:25tube
00:49:26might be divided
00:49:27by barriers
00:49:28so that the stripes
00:49:29don't mix.
00:49:30But,
00:49:31if you cut it
00:49:31in half,
00:49:32you'll see that
00:49:33it has only
00:49:34one interior chamber.
00:49:36As it happens,
00:49:37there's a lot
00:49:38of science
00:49:39behind the making
00:49:40of striped toothpaste.
00:49:41According to
00:49:42a specialist,
00:49:43they have to ensure
00:49:44that the paste
00:49:45in all the
00:49:46stripes
00:49:46has the same
00:49:47physical properties.
00:49:48This way,
00:49:49the colors
00:49:49are naturally
00:49:50prevented
00:49:51from mixing
00:49:51with one another.
00:49:52That's why,
00:49:53if you tear
00:49:54a tube open,
00:49:55you'll see
00:49:55something that
00:49:56looks like
00:49:56several slices
00:49:57of pizza
00:49:58in different colors.
00:50:00If you open
00:50:01your closet,
00:50:02you're bound
00:50:03to find
00:50:03at least
00:50:03a few
00:50:04wooden hangers.
00:50:05Usually,
00:50:06they're made
00:50:06of cedar wood,
00:50:08which is a
00:50:08natural moth
00:50:09repellent.
00:50:10So,
00:50:11cedar hangers
00:50:12actually protect
00:50:12your clothes
00:50:13from moth
00:50:14infestation.
00:50:15For some
00:50:16people,
00:50:16more than
00:50:17others,
00:50:18eyeliner is
00:50:19an everyday
00:50:19must.
00:50:20Boy,
00:50:21isn't it?
00:50:21But,
00:50:22did you know
00:50:22that back
00:50:23in ancient
00:50:24Egyptian times,
00:50:25both men
00:50:26and women
00:50:27used cool
00:50:27eyeliners to
00:50:28protect their
00:50:29eyes from
00:50:29the sun's
00:50:30glare?
00:50:31Way to go
00:50:31for the Egyptians
00:50:32for figuring
00:50:33that out!
00:50:34Now,
00:50:35if I could just
00:50:35learn to walk
00:50:36like one…
00:50:38normally,
00:50:39we use
00:50:39headrests for
00:50:40the purpose
00:50:41of,
00:50:41well,
00:50:42resting our
00:50:43heads,
00:50:43right?
00:50:44Well,
00:50:45not only!
00:50:46As it turns out,
00:50:47headrests can be
00:50:48easily removed
00:50:50from the seats
00:50:50and used to
00:50:51break car windows
00:50:52in case of
00:50:53emergencies.
00:50:55Now,
00:50:56this one is a
00:50:56trick very few
00:50:57people know
00:50:58about.
00:50:58You probably
00:50:59place your
00:51:00doormat
00:51:01horizontally,
00:51:01like most of
00:51:02us do.
00:51:03But doormats
00:51:04serve the purpose
00:51:05of absorbing
00:51:06dirt from the
00:51:06soles of your
00:51:07shoes before
00:51:08you enter your
00:51:09home.
00:51:09So,
00:51:10for this function
00:51:11to work as
00:51:12it's meant to,
00:51:13the best way
00:51:13to place a
00:51:14doormat is
00:51:15vertically.
00:51:16This way,
00:51:17you take more
00:51:18steps on the
00:51:19top of the
00:51:19doormat before
00:51:20entering your
00:51:21house.
00:51:22And,
00:51:23last but not
00:51:24least,
00:51:24now,
00:51:25I don't want
00:51:25to be accusatory
00:51:26here,
00:51:27but you have
00:51:28probably been
00:51:28vacuuming your
00:51:29house the
00:51:30wrong way,
00:51:31and I can
00:51:32prove it.
00:51:33Most people
00:51:34just vacuum
00:51:34floors and
00:51:35carpets in
00:51:35one direction,
00:51:36or move the
00:51:37brush back and
00:51:38forth several
00:51:39times,
00:51:39thinking they've
00:51:40got all the
00:51:41dust out.
00:51:42But,
00:51:43according to
00:51:43cleaning
00:51:43professionals,
00:51:44the best way
00:51:45to vacuum
00:51:46is in rows.
00:51:47First,
00:51:48you go forward
00:51:48with the brush
00:51:49until you arrive
00:51:50at the end of
00:51:51the row.
00:51:51Then,
00:51:52you fluff the
00:51:53carpet up and
00:51:54move back down
00:51:55along the same
00:51:56row,
00:51:56gathering the
00:51:57dust that
00:51:58wasn't collected
00:51:58in the first
00:51:59sweep.
00:52:00Talk about
00:52:00efficient cleaning.
00:52:01On the other
00:52:02hand,
00:52:03my idea of
00:52:04housecleaning is
00:52:05to sweep the
00:52:06room with a
00:52:07glance.
00:52:08Hey,
00:52:08I don't want to
00:52:09disturb that
00:52:09protective layer
00:52:10of dust.
00:52:13You just spent
00:52:14the entire
00:52:15morning running
00:52:16errands up and
00:52:17down the street,
00:52:17and you finally
00:52:18stop to treat
00:52:19yourself to a
00:52:20cup of coffee.
00:52:21You enter the
00:52:22nearest coffee shop,
00:52:23place your order,
00:52:24and notice that
00:52:25actually, you
00:52:26really need to
00:52:26use the bathroom.
00:52:28It's a regular
00:52:28looking public one
00:52:29with multiple
00:52:30stalls.
00:52:31As you pick
00:52:32yours, the one
00:52:33in the middle,
00:52:33you get inside
00:52:34and your mind
00:52:35starts to wander.
00:52:37Why on earth
00:52:38do bathroom doors
00:52:39have a half-inch
00:52:39gap between the
00:52:40door and the
00:52:41lock, and why
00:52:42on earth do
00:52:42they have a
00:52:43huge gap between
00:52:44the door and
00:52:45the floor?
00:52:46Can we have a
00:52:46drumroll for this
00:52:47moment, please?
00:52:49Well, my friend,
00:52:50there is not only
00:52:51one specific reason
00:52:52why public
00:52:53bathroom doors have
00:52:54so many gaps in
00:52:55them, but rather
00:52:56several.
00:52:57Public toilets are
00:52:58designed to make
00:52:58people spend as
00:52:59little time there
00:53:00as possible.
00:53:01You aren't
00:53:02supposed to feel
00:53:02comfortable or at
00:53:04home.
00:53:04So the design would
00:53:05have to reflect this
00:53:06notion.
00:53:07Here come the
00:53:08gaps.
00:53:09In some
00:53:09bathrooms, gaps
00:53:11are so big that
00:53:12users may even
00:53:13feel self-conscious
00:53:14about doing their
00:53:15business out of
00:53:16preoccupation that
00:53:17the rest of the
00:53:17people standing in
00:53:18line will see
00:53:19them.
00:53:20Then there's the
00:53:21matter of pricing.
00:53:22Making custom
00:53:23doors can be a
00:53:24heavy burden for
00:53:25the people building
00:53:26public toilets.
00:53:27This would mean
00:53:28understanding exact
00:53:29measurements so that
00:53:30doors would always
00:53:31fit the mold of the
00:53:32stalls it's supposed
00:53:33to be installed
00:53:34into.
00:53:35Now, not all the
00:53:36gaps in public
00:53:37bathrooms are
00:53:37necessarily the
00:53:39same size.
00:53:39They may vary, even
00:53:41if this variation is
00:53:42small and often
00:53:43unnoticeable.
00:53:44So these gaps
00:53:45actually help to
00:53:47reduce the margins
00:53:47of errors and to
00:53:49turn production more
00:53:50cost-effective for the
00:53:51people financing
00:53:52them.
00:53:52In case a door comes
00:53:54wider or more narrow
00:53:55than it should, the
00:53:56gap regulates the
00:53:57differences and allows
00:53:59for their installation
00:54:00anyway.
00:54:01There is also the
00:54:02case of air
00:54:03circulation.
00:54:03The last thing you
00:54:05want to do in a
00:54:05public bathroom is to
00:54:07trap odors, so you
00:54:08need a little space
00:54:09under and between
00:54:10the doors to allow
00:54:11the air to flow.
00:54:13Finally, the gaps are
00:54:14a big safety measure.
00:54:15It can always allow
00:54:17for people on the
00:54:17outside to see if
00:54:19someone inside a
00:54:20stall isn't feeling
00:54:21too okay and maybe
00:54:22need some help.
00:54:23And what about that
00:54:25extra hole in the
00:54:26upper part of the
00:54:27sink?
00:54:27It has a name in
00:54:28everything, the
00:54:29overflow hole, and
00:54:31it's designed to keep
00:54:32the sink from
00:54:32flooding.
00:54:33So in case someone
00:54:34forgets and keeps the
00:54:36faucet going for too
00:54:36long, or the sink
00:54:38gets clogged and
00:54:39water can't drain down
00:54:40from the main drain
00:54:41hole, the overflow
00:54:43hole comes in to
00:54:44save the day.
00:54:45Let's say it buys
00:54:46you a little time
00:54:47before you have the
00:54:47entire bathroom floor
00:54:48flooded.
00:54:49Have you ever
00:54:50noticed how
00:54:51satisfying closing
00:54:52the door of a car
00:54:53can be?
00:54:54Car manufacturers
00:54:55devote a great deal
00:54:56of time to
00:54:57designing these
00:54:58sounds.
00:54:58Studies have shown
00:54:59that they create a
00:55:00perceived sense of
00:55:01quality in the buyer.
00:55:02It all begins with
00:55:04the primary material.
00:55:05While older cars used
00:55:07to be made with
00:55:07heavier materials,
00:55:09car doors nowadays
00:55:10are produced with
00:55:11lighter tin, which
00:55:12can make a rather
00:55:13unpleasant metallic
00:55:14sound once you
00:55:15shut them closed.
00:55:16So car companies
00:55:17employ sound engineers
00:55:19to ensure that there
00:55:20is the exact amount
00:55:21of foam, mats, and
00:55:23tin in a car's
00:55:23composition to make
00:55:25the most comforting
00:55:26sound possible.
00:55:27And what about
00:55:28those tiny dots on
00:55:29the top of your
00:55:30car's front window?
00:55:31The pattern of
00:55:32these little black
00:55:33dots minimizes
00:55:34distractions for
00:55:35your eyes.
00:55:36This black part,
00:55:37also known as
00:55:38frit, normally
00:55:39gets warmer than
00:55:40the clear parts,
00:55:41which prevents the
00:55:42windshield from
00:55:42deforming.
00:55:43And no, the tab
00:55:45under your rearview
00:55:46mirror is not made
00:55:47only for the purpose
00:55:48of hanging fluffy
00:55:49dice or aromatic
00:55:50pleasing air
00:55:51fresheners.
00:55:52It's actually a
00:55:53switch that allows
00:55:54you to adjust the
00:55:54position of the
00:55:55mirror, depending
00:55:56on the time of day.
00:55:57Flip it one way,
00:55:58and it's the
00:55:59daytime driving
00:56:00mode.
00:56:00Flip the other,
00:56:01and you're ready
00:56:02to drive safely
00:56:03during nighttime
00:56:04as it tones down
00:56:05the glare coming
00:56:06from headlights of
00:56:07the cars behind
00:56:08you.
00:56:08Next time you head
00:56:09out to the
00:56:10supermarket, make
00:56:11sure to keep this
00:56:11in mind.
00:56:12In case you don't
00:56:13have a coin to
00:56:14unlock these
00:56:14shopping carts,
00:56:15there is a well-kept
00:56:17secret that can
00:56:17help you out.
00:56:18If you have your
00:56:19house keys on you,
00:56:21check for a
00:56:21rounded key head.
00:56:22If you happen to
00:56:23find one, try using
00:56:25it to unlock the
00:56:26cart.
00:56:26It should fit
00:56:27perfectly in there,
00:56:28replacing the
00:56:29need to carry
00:56:29coins around.
00:56:30Because, if we're
00:56:31being honest, who
00:56:32still has them?
00:56:34Elevators.
00:56:35If you want to
00:56:35ride them on your
00:56:36terms, and your
00:56:37terms only, make
00:56:38sure to try
00:56:39something out.
00:56:40Most elevators have
00:56:41a secret button
00:56:42combination you can
00:56:43use to skip all the
00:56:44other selected floors
00:56:45and go directly to
00:56:46the one of your
00:56:47choosing.
00:56:48This might work
00:56:49out, especially on
00:56:50those days when
00:56:51you've pressed 13.
00:56:52But you wanted to
00:56:53press 33.
00:56:54On most elevators,
00:56:56this works once you
00:56:56simultaneously press the
00:56:58closed door button
00:56:59together with your
00:57:00floor number.
00:57:01This should help you
00:57:02get to your floor
00:57:03without stopping.
00:57:04Some elevators require
00:57:05you to double-press the
00:57:07selected floor numbers,
00:57:08as double-pressing will
00:57:09often cancel the
00:57:10previously made request.
00:57:12While other elevators
00:57:13require you to hold
00:57:14the open door button
00:57:16and then double-press the
00:57:17buttons of the floors
00:57:18you'd like to cancel.
00:57:19Now, to stay out of
00:57:20trouble, it's best not to
00:57:22cancel the floors of the
00:57:23other people in the
00:57:24elevator.
00:57:25They won't take it
00:57:26kindly.
00:57:27Also, keep in mind that
00:57:28there are elevators that
00:57:29might not have this
00:57:30function.
00:57:31Now, for honey lovers
00:57:32out there, go ahead and
00:57:33raise your hand.
00:57:34If your pot of golden
00:57:35honey is crystallized,
00:57:37know that it is actually
00:57:38a good sign.
00:57:40Crystallized honey means
00:57:41that it hasn't been
00:57:42pasteurized, which means
00:57:44better product quality.
00:57:45With a decrease in
00:57:46temperature, the natural
00:57:48ingredient of honey,
00:57:49also known as glucose,
00:57:51will make it
00:57:51crystallize.
00:57:52Now, try making the
00:57:54best of it.
00:57:54To add some texture to
00:57:55your oatmeal or toast,
00:57:57add a layer of
00:57:58crystallized honey and
00:57:59enjoy nature's sugar.
00:58:01And if you don't like
00:58:02crystallized honey,
00:58:03plop it in the microwave
00:58:04for a minute or two.
00:58:05Ah, winter and fall.
00:58:07You know what this means,
00:58:08right?
00:58:09Sweater weather.
00:58:10But there's nothing more
00:58:11annoying than wearing
00:58:12your beautiful wool sweater
00:58:14and itching yourself all
00:58:16the way through it.
00:58:17Actually, I can be more
00:58:18annoying than that, but
00:58:19let's talk about itchy
00:58:20sweaters.
00:58:21To keep this from
00:58:22happening again, here's
00:58:23the secret.
00:58:24Turn your sweater inside
00:58:26out and soak it in cold
00:58:27water.
00:58:28Add two or three tablespoons
00:58:29of vinegar and let it sit
00:58:31for a while.
00:58:32Then, drain the water.
00:58:34Now, while the sweater is
00:58:35still wet, massage a
00:58:37generous amount of hair
00:58:38conditioner into the
00:58:39fibers of the wool.
00:58:40After letting it soak in
00:58:42the hair conditioner for
00:58:43about 30 minutes,
00:58:44gently press the excess
00:58:45water out of the wool
00:58:47and leave it to dry flat on
00:58:48Natal.
00:58:49There you go!
00:58:50No more itchy sweater.
00:58:52Any fast food restaurant you
00:58:54go to will hand out small
00:58:55paper cups for customers to
00:58:57fill with their ketchup,
00:58:58mustard, or barbecue sauce.
00:59:00But if you're eating some
00:59:02chicken nuggets or trying to
00:59:03dip your burger into the cup,
00:59:05there's always that bit of
00:59:06sauce that seems impossible to
00:59:08reach.
00:59:09Next time, try unfolding the
00:59:11cup.
00:59:11It'll turn into a small
00:59:13paper plate, and this way,
00:59:14you'll get all the ketchup
00:59:16you poured in the first
00:59:17place.
00:59:18Padlocks, used in outdoor
00:59:20environments, should be
00:59:21clean and lubricated every
00:59:23three months.
00:59:24Regular lubrication will help
00:59:26prevent padlocks from
00:59:27freezing in cold weather
00:59:28conditions.
00:59:29Look for the tiny hole on
00:59:30the bottom of the lock.
00:59:32Then, pour oil into it,
00:59:33and there you go!
00:59:34It opens again!
00:59:36One thing we often neglect is
00:59:38a point in an ointment cap.
00:59:40These pointy surfaces were
00:59:42designed to help us break the
00:59:43tinfoil protection of the
00:59:45ointment tube.
00:59:46You just turn the cap over
00:59:47and break the ointment seal
00:59:49with its own cap, and there
00:59:51you go!
00:59:52After a long day of work,
00:59:54all you really need to do is
00:59:56a bubble bath.
00:59:56You turn on the hot water and
00:59:58let it run for a few minutes.
00:59:59You might even light a candle
01:00:01and pour some essential oils
01:00:03into the water.
01:00:04Then, in comes the liquid
01:00:06soap.
01:00:06You stir the water until the
01:00:08entire surface of the tub
01:00:09water is crammed with bubbles
01:00:11and make your way in.
01:00:13The bubbles in a bubble bath
01:00:15have a fundamental primary
01:00:16function.
01:00:17Their job is to preserve the
01:00:18water's temperature, just so
01:00:20you can have warm water for
01:00:22longer.
01:00:23Do you have sweaty feet?
01:00:24Weird question, I know.
01:00:26But if you're one of these
01:00:27people, here's some good news.
01:00:29All is not lost.
01:00:31Try putting a dry teabag inside
01:00:33your shoes and storing it in a
01:00:35dry place for a while.
01:00:36The teabags will absorb the
01:00:38humidity and the smell off the
01:00:40soles of your shoes.
01:00:41So, here I am thinking,
01:00:43shouldn't we have learned these
01:00:44things in school?
01:00:45Well, either way, if you learned
01:00:47something new today, make sure to
01:00:49tell us about it in the comments
01:00:50below.
01:00:51Be well.
01:00:54Be well.
