00:00Many shirts have two buttons on the cuffs, but only one buttonhole.
00:05So what is the second button for?
00:08Turns out you can use it whenever you're wearing a watch, so the cuff is looser.
00:14Most clothing items you buy come with a small bag of fabric or a button, or both.
00:20Buttons obviously can be used as a replacement if you lose the original ones.
00:24Pieces of fabric can be used to patch up a hole, but most importantly, it's a tester.
00:30You can use it to test different washing products on it and see what happens to the fabric.
00:36Some umbrellas have a tip at the top, and it turns out it's not just a pretty design.
00:42When going inside on a rainy day, you should just close your umbrella and tap the tip against the floor
00:48to drain the water faster and more effectively.
00:52Many backpacks have this diamond with two parallel cutout slits on its front, and it's there for your comfort.
01:00You can attach something to it, like a water bottle or shoes.
01:04It comes especially handy if you travel somewhere or go hiking, so you don't have to hold your stuff.
01:11Okay, the next thing is gear loops, and probably from the name of it, you already have an idea what
01:17they're there for.
01:18You can strap in some useful gear you need to have with you, like trekking poles or shovels.
01:23Some gear will need to be secured to do it.
01:27Drop the handle through the loop and rotate it upward.
01:30Then, secure it with the elastic hook at the top, and you're golden.
01:35On the back of many makeup and hygiene products, you can find this symbol with a marking, like 6M, 12M,
01:43and 24M.
01:45This is the number of months this product can serve after you open it and before you should throw it
01:51out.
01:53The two sides of a cotton pad are different because each of them has a particular purpose.
01:58A cotton pad has several layers to ensure that it's soft, strong, and can absorb liquids.
02:05The edge is stitched to hold it all together.
02:08The smooth side of a pad is for applying products, like tonics and lotions.
02:13And the embossed side is best for cleansing and makeup removal.
02:19Also, any pack of cotton pads has those strings on the sides.
02:23They're there so you can hang the package somewhere.
02:26Then, you can open the package at the bottom, where the perforated line is, and take them out.
02:32Did you know that there is an efficient way to pull a thread from yarn?
02:37When you pull from the outside, the yarn rolls away, so you need to hold it.
02:41However, if you pull it from the center, it will stay together.
02:46We're all familiar with staplers, but I bet you don't know all its secrets.
02:51Most staplers have a compartment to store spare staples, which can be located either on top or at the bottom.
02:59Also, surprise! This metal plate you press staples against can be turned around.
03:04This way, the device will be able to staple your documents by turning the metal ends outwards.
03:11No need to wonder whether you need to get a smaller or bigger container.
03:16Turns out, plastic food containers have volume measurements on their bottoms, indicating how much food they can fit.
03:24Ceiling fans come with a small switch on the inside of the blade.
03:27You might not have noticed it because it's not in plain sight, so check yours out.
03:32This switch allows you to change the direction of rotation.
03:36Now, why would you want to do that?
03:38The blades of a fan push the air in different directions, depending on the way they rotate.
03:44In the summer, you need the air to be pushed down to create the effect of a breeze.
03:50In the winter, the direction should be changed so that the air is pushed towards the ceiling.
03:55It then heats up before going down the walls.
04:00Have you noticed that the gas tank sign on cars' dashboards has a little arrow next to it?
04:07Well, this arrow has a purpose.
04:09It points at the side of the car where the gas tank is located.
04:13It's very useful for forgetful people who constantly wonder where the gas tank is,
04:18and also for those who drive rentals once in a while.
04:21The answer is right in front of your eyes.
04:23If you can't find the arrow on your panel, then the fuel hose on the icon indicates the side instead.
04:32All car tires have 12-digit numbers printed on them,
04:36and they're actually important codes for car owners if they want to get the right tire.
04:41The first letter identifies the type of tire.
04:44P stands for a tire for light passenger cars, and LT is for heavy vehicles.
04:50Then, the following numbers stand for the width of the tire, its radial, and its diameter.
04:58Measuring tapes have that metal stud on the end,
05:01which you can use to attach the tape to the surface you measure.
05:04This way, you don't need to hold it yourself.
05:07But there's also a small slot, which can be used to hang the tape on a nail,
05:12again to free your hands and keep measuring.
05:16The bottom of the end of the tape has a ridged edge.
05:20It will help you make a mark if you don't have a marking tool with you.
05:25On the tape, there are black diamonds that are placed every 19.2 inches.
05:30They're useful for construction workers when spacing engineering joists.
05:34They can also be useful for you if you want to hang something heavy, for example.
05:40The diamond will mark the exact center of a wooden joist.
05:44Those are placed 16 inches apart from one another.
05:47There, you can drill something to that center
05:50to make sure whatever you hang is safely attached to the joist
05:53instead of the unreliable thin wall.
05:56Pictures will survive, but it's particularly important if you're hanging something heavy.
06:02Did you know that batteries have an expiration date?
06:06Yes, it's printed right on their label, but I've never noticed it before.
06:11The expiration date doesn't mean you can't use it after that.
06:15It's more like a recommended usage period,
06:18after which the manufacturer can't guarantee full battery life
06:23due to deteriorated components.
06:27These little feet keyboards have are actually a standard.
06:32The height of a keyboard should be adjustable,
06:35allowing the angle between 0 degrees and 15 degrees.
06:40The reason to fold the feet out is for you to see the keys better,
06:45in case you don't type blindly.
06:47A little problem that comes with it is that, in this case,
06:51your wrists are bent,
06:53and it's not good to keep them in this position for a long time.
06:59Pans have those holes on the ends of their handles.
07:02They're not just there for you to hang them.
07:04You can also place your cooking spoon in there.
07:08It'll hang right above the pan,
07:10and the sauce will not spill around.
07:13Make sure to tap off the sauce or food beforehand, though,
07:17so that it doesn't go down the spoon's handle.
07:22Stickers with numbers you can find on fruits
07:24can tell you some information on how the food was grown.
07:29A four-digit code that starts with a four
07:32means that the fruit was grown conventionally,
07:36meaning it contains chemicals and pesticides.
07:40So your best choice should be a fruit with a five-digit number.
07:44And if you see the number nine,
07:46it indicates that the fruit is certified organic.
07:51On the bottom of plastic bottles,
07:54you can often notice a mark of a triangle
07:57with a number engraved in the middle.
08:00This number specifies the type of plastic
08:03that was used to produce the bottle.
08:05These codes help people and local recycling centers
08:10to sort returns.
08:12Products that were made of plastic of types 1 and 2
08:16are the easiest ones to recycle.
08:19Plastics of types 3 through 7 are tougher to recycle.
08:27What's hiding inside Coca-Cola cans
08:29and regular household batteries?
08:31Why do magnets affect breakfast cereals?
08:34Do crosswalk buttons actually work
08:37or are they just useless decorations?
08:40What does that USB symbol really mean?
08:43I'm not sure I know the answers to these
08:46and similar questions,
08:47but I'm eager to learn the truth together with you.
08:50Let's find it out.
08:52Coca-Cola cans have a secret few people know about.
08:56Here's a Coke can.
08:58Let's submerge it in a highly corrosive alkaline solution.
09:01The aluminum dissolves due to a process known as hydrolysis
09:05and we can see a plastic liner inside the can.
09:08It's made from a polymer or epoxy resin
09:11and serves as some kind of a protective barrier
09:14between the aluminum walls of the can
09:16and the rather acidic soda.
09:19Despite a popular myth,
09:21household batteries don't actually contain liquid
09:24and if you accidentally cut them open,
09:26no toxic liquid will spill.
09:28Most of them are dry cell batteries
09:30which are made of electrochemical cells.
09:32Those convert chemical energy into electrical energy.
09:36Larger batteries often house numerous small cells within them too.
09:40Even Tesla vehicle batteries consist of multiple small cells.
09:44When combined, they easily provide the necessary voltage.
09:50Most toothbrushes have differently colored bristles,
09:53but they aren't just pleasing to the eye.
09:55Those bristles, often blue, have a functional purpose.
09:58They're called toothbrush indicators
10:00and their colors fade as you use the brush.
10:03The American Dental Association recommends changing your toothbrush
10:07at least four times a year.
10:09And by getting paler,
10:10these bristles help you figure out
10:12when it's time to replace your toothbrush.
10:15You'll probably agree that there's no better snack than a pack of chips.
10:19Some are flat, others have ridges.
10:21Is it just aesthetics?
10:23Not really.
10:25The main purpose of those lines on some kinds of chips
10:27is to help with the distribution of spices and seasonings.
10:30In other words,
10:31all those substances that make your chips taste like cheese
10:34are mostly stored inside the lines.
10:37Plus, the lines make chips crunchier.
10:41Now, this one might be a surprise,
10:43but some breakfast cereals are magnetic.
10:45That's because they're often fortified with iron
10:48in the form of a fine powder.
10:50Due to the added iron,
10:52cereal flakes get attracted to magnets.
10:54All this may sound kind of alarming,
10:56but in reality,
10:57the iron content in the flakes is minimal
10:59and doesn't pose any threat to your health.
11:03That clear fluid in gel pens
11:05is called the ink follower or stopper fluid.
11:08The gel in such pens contains pigment particles
11:10dissolved in a polymer solution.
11:13The main task of the stopper fluid
11:15is to be a barrier
11:16to prevent the gel from evaporating or leaking out.
11:19Without this transparent fluid,
11:21your gel pen wouldn't function.
11:24The fluid always stays in one position
11:26and doesn't get dissolved with the gel.
11:28Neither does it move backwards
11:30or flow out of the pen.
11:33Many pedestrian crosswalk buttons,
11:36namely in New York,
11:37are placebo buttons.
11:38They do literally nothing when you press them.
11:41Originally, they were functional
11:43after being introduced in 1964,
11:45but today,
11:46most of them don't affect traffic lights,
11:48which are programmed
11:49based on the real needs of the traffic flow.
11:52Why do such buttons even exist then?
11:54It's a simple psychological trick,
11:57providing you with an illusion of control.
12:00You might have noticed
12:01that movie theater seats
12:02are almost always red.
12:05This choice isn't random.
12:07It has strategic importance,
12:08which is rooted in visual science.
12:11The thing is,
12:12red light has a longer wavelength.
12:14It means that it's the first color
12:15to disappear in low light.
12:17It allows the audience
12:18to concentrate better on the screen
12:20once the movie begins.
12:21Such a design choice
12:22enhances the viewing experience
12:24by minimizing distractions.
12:27Speed bumps are crucial
12:29for pedestrian safety,
12:30but at the same time,
12:31they can seriously increase car emissions
12:34due to the non-stop acceleration
12:36and deceleration they cause.
12:39To address this issue,
12:40some cities like London
12:41are testing fake speed bumps.
12:43Those are optical illusions
12:45painted on the road.
12:46They look raised
12:48from a driver's perspective,
12:49but in reality,
12:50they're flat.
12:51Authorities hope that this approach
12:53will slow down drivers
12:54without having a negative impact
12:56on the environment.
12:59Soda bottles are always filled
13:01in such a way
13:02that there's some space
13:03between the liquid and the cap.
13:05That's because soda
13:06contains carbon dioxide.
13:07It's a gas that can expand
13:09once the bottle's heated.
13:10If there's no gap in the bottle,
13:12it can break
13:13because of the pressure
13:14building inside.
13:16Also, when you open your drink,
13:18the gases go out
13:19in the form of bubbles,
13:20making the drink overflow.
13:21The gap helps
13:23with this problem, too.
13:26The USB symbol,
13:28looking like a trident,
13:29has always sparked
13:30multiple speculations
13:31about its origin.
13:33One popular idea
13:35is that it represents
13:36Neptune's trident
13:37and symbolizes power
13:38and adaptability.
13:39But there's also
13:41a little bit less
13:42exciting theory.
13:43A man who claimed
13:44to have designed the symbol
13:45in the 1980s
13:46stated that it was supposed
13:47to represent connectivity.
13:49The large circle
13:50symbolizes a computer,
13:52while the attached shapes,
13:53the circle,
13:54the triangle,
13:55and square,
13:56stand for different outputs.
13:59The design of a tennis racket
14:01has a specific feature
14:03known as the throat.
14:04It's an open space
14:05below the head of the racket.
14:07This space isn't just
14:09for storing balls,
14:10it also improves
14:11the racket's aerodynamics
14:12by letting air pass through.
14:14It seriously reduces drag
14:16during swings.
14:19Speaking of tennis,
14:20tennis courts are usually
14:21built with a north-south
14:22orientation.
14:24It helps minimize
14:25the impact of the sun's
14:26position during the game,
14:28ensuring that neither player
14:29has the sun directly
14:30in their eyes.
14:32Look closely
14:33at a tram's overhead lines
14:35and you'll see
14:36that its contact wires
14:37zigzag back and forth
14:39instead of going
14:40in a straight line.
14:41That's because all trams
14:43have pantographs
14:44attached to their roofs.
14:45The upper part
14:46of the pantograph
14:47is gradually worn down
14:48by the overhead wire
14:50and eventually
14:50needs to be replaced.
14:52To wear it down evenly,
14:54the wire is not installed
14:56strictly along the tram's path,
14:58but in zigzag patterns.
15:00As the tram moves,
15:02the pantograph slides
15:03along the wire
15:04and it wears down evenly.
15:07Those cone-shaped
15:08water cooler cups?
15:10Their shape
15:11is intentionally designed
15:12to prevent users
15:13from setting the cups down.
15:14This allows employees
15:16to minimize the risk
15:17of spilling water
15:18on their desks
15:19around various
15:20electronic devices.
15:21Plus,
15:22less material
15:22is used to produce
15:23cone-shaped cups,
15:24which makes the process
15:26less wasteful
15:27and more cost-effective.
15:28It also kind of
15:30supports sustainability
15:31by encouraging people
15:32to drink their water quickly
15:33and dispose of their cups
15:35immediately after.
15:38Most suitcases
15:39have two zipper pulls
15:41and it serves
15:41several purposes.
15:43First of all,
15:44if one zipper fails,
15:46the other can keep
15:47the suitcase closed.
15:48Even better,
15:50having two zippers
15:50allows you to have
15:51easier access
15:52to small sections
15:53of your suitcase
15:54without having to
15:55open it entirely.
15:57And finally,
15:58when you have two zippers,
16:00you can connect them
16:01with a padlock
16:01for increased security.
16:05Some plastic milk containers
16:07have dents
16:07on their sides.
16:08These dents
16:09serve several purposes.
16:11When milk spoils,
16:12it usually causes swelling
16:14and high-pressure buildup
16:15inside the container.
16:16That's when the dent
16:17pops out
16:18and doesn't let
16:19the jug blow up.
16:20Plus,
16:21if you decide
16:21to freeze the milk,
16:23it will expand
16:23like any other fluid.
16:25And then again,
16:27the indentation
16:27will pop out
16:28and prevent the container
16:29from breaking
16:30inside your freezer.
16:33If you ever had
16:34a problem figuring out
16:36why fake pockets exist,
16:38you need to hear this.
16:39The main reason
16:40is that if a clothing item
16:42has a specific cut
16:43or shape,
16:44pockets may spoil it.
16:45They can alter
16:46the item's shape
16:47either in the warehouse
16:48or already on
16:49the retail rack.
16:51The solution?
16:52Getting rid of the pockets
16:53in key areas.
16:54Plus,
16:55fake pockets
16:56are obviously cheaper
16:57and they don't
16:58get stretched out.
17:01The thermos
17:01wasn't actually invented
17:03to keep your coffee warm.
17:05It was made
17:06by a Scottish scientist
17:07who wanted a safe place
17:08to keep his chemicals
17:09at a stable temperature.
17:11So,
17:12he took two bottles,
17:13put the smaller one
17:14inside the bigger bottle
17:15and vacuumed out
17:16the air between them.
17:21Here's how you can
17:22protect your bank card
17:23from potential fraudsters.
17:25Use a marker
17:26and cover the last
17:27four digits.
17:28You can also use
17:29a sticker that's easy
17:30to remove
17:30and place it
17:31over the security code.
17:33Have you had a houseguest
17:34that didn't use a coaster?
17:36Get a hair dryer
17:37and hold it a couple
17:38of inches away
17:38from the stain.
17:39Blow it on medium heat
17:41for a couple of minutes
17:41to evaporate the watermark.
17:43If a faded ring remains,
17:45mix equal amounts
17:46of vinegar and olive oil
17:47in a bowl.
17:48Wipe it onto the marked area
17:49and rub it in
17:50until the stain disappears.
17:52Then wipe it off.
17:53Don't waste time
17:54scrubbing the burnt stains
17:55off the bottom of a pan.
17:57Instead,
17:58fill it with water
17:59and add three tablespoons
18:00of salt.
18:01Let it sit overnight
18:02as the salt dissolves
18:03the burnt marks.
18:04And in the morning,
18:05pour the water
18:06out of the pan.
18:07This way,
18:08it will be much easier
18:09to scrub all that grease off.
18:11Picture this.
18:12You're on vacation
18:13and your shirt
18:13has become all crinkled
18:14inside the luggage.
18:15You need it tonight,
18:17but the hotel
18:17doesn't have an iron.
18:19Don't panic.
18:19Hang the shirt up
18:20in the bathroom
18:21and while you relax
18:22in a hot shower,
18:23the heat and moisture
18:24will unwrinkle your shirt.
18:26It won't be perfect,
18:27but it will get much better
18:28without any effort.
18:29The football is on
18:31and it turns out
18:32you've run out
18:32of standard batteries.
18:34You can use
18:34a smaller battery instead
18:36that easily fits inside.
18:38Now take some aluminum foil
18:39and crunch it up.
18:40Fit it into the gap
18:42on the negative
18:42or flat end
18:43of the battery.
18:44All done.
18:45You can turn on
18:46the TV now.
18:47Once your flip-flops crack
18:49and the plug
18:49easily slips out
18:50of the hole,
18:51it's normally a sign
18:52that you need
18:53a new pair,
18:53but there's a way
18:54to extend their mileage.
18:56Push the plug
18:57back through the hole,
18:58then take a bread clip
18:59and attach it
19:00to the end.
19:01The clip will provide
19:02enough support
19:02for the plug
19:03to remain in place.
19:05You've received a package
19:06and the receipt
19:07is taped on.
19:08You've managed
19:08to detach it
19:09from the box,
19:10but how to separate
19:11the tape
19:11without ripping the paper?
19:13Hold both ends
19:14of the tape apart
19:15and by pulling it slowly,
19:17the tape stretches
19:18and separates itself
19:19from the paper
19:20without tearing it apart.
19:22Ziploc bags are perfect
19:24to keep things dry,
19:25but it would be great
19:26if they were larger.
19:27Take two
19:28and turn one of them
19:29inside out.
19:30They can now connect
19:31and work as one large bag,
19:33big enough
19:34to protect a keyboard.
19:36There's no need
19:37to carry your keys
19:38in your hand
19:38when you go for a job.
19:39Instead,
19:41put them inside
19:41your pocket,
19:42take a rubber band,
19:43then tie it around
19:44the pocket
19:44from the inside.
19:45This stops the keys
19:46from falling out.
19:48You've broken
19:49your key in the door.
19:50It's stuck.
19:51Great!
19:52Arranging for a locksmith
19:54could cost up to $100,
19:55but for a cheaper
19:57and quicker option,
19:58try using a hot glue stick.
19:59Heat the end
20:00with a lighter
20:01and once it's warm
20:02enough to melt,
20:02push the glue
20:03into the keyhole.
20:04The melted glue
20:05will enter the available
20:07space covering
20:08part of the key.
20:09Once it cools,
20:10it compresses
20:11and gains a strong hold
20:12of the key's end.
20:13Now,
20:14just pull it out.
20:16If you need to siphon liquid
20:18through a hose
20:19and want to avoid
20:20using your mouth,
20:20put one end in the liquid
20:22and hold the other upwards
20:23with your thumb
20:24closing the top.
20:25Now shake up and down.
20:27This jiggle motion
20:27pushes liquid upwards
20:29a little each time.
20:31And once it reaches the top,
20:32lower the exit point
20:34and let gravity do the rest.
20:36You've left your keys
20:37locked inside the car.
20:38It's an older model
20:39with a roll-down window.
20:41You could get the coat hanger
20:42and begin the long process
20:43of finding the lock
20:44or use duct tape.
20:46Make about 20
20:47two-foot-long strands.
20:49Stick them onto the window,
20:51allowing enough room
20:51for the tape
20:52to grab onto
20:53at the bottom.
20:54Then with a friend,
20:55take the ends of the tape,
20:56holding them together
20:57and pull downwards.
20:58The force will allow
21:00the window to lower enough
21:01that you can unlock the door.
21:03While drilling long screws
21:05into hardwood,
21:06your old drill
21:06might not have enough power,
21:08leaving them only halfway in.
21:10Before the drill gives up,
21:12get a block of wax
21:13and scrape the edges
21:14of the screws with it.
21:15The wax works like a lubricant,
21:17melting as it gets warm
21:18and providing easy entry
21:20for the screw.
21:21You're out camping,
21:22but you didn't bring anything
21:24to light the barbecue.
21:25Take a small plastic bag
21:26that won't leak,
21:27fill it up with water
21:28and close it tight,
21:30making a round bubble.
21:31Hold it over where you want
21:33to catch the light
21:33from the sun.
21:34The bag of water
21:35will work like a magnifying glass,
21:37starting up the barbecue,
21:39just as long as it's a sunny day.
21:41Missing a corkscrew
21:42or a cork breaking halfway?
21:44By using a stove lighter,
21:46heat the top of the bottle.
21:47The heat slightly expands the glass
21:49and this forces the cork
21:51out the top.
21:52You've superglued
21:53your fingers again.
21:55Take some salt
21:56and pour it on top
21:56of your stuck fingers.
21:57Put your fingers
21:59into the water
21:59and slowly rub.
22:01The mixture will dissolve the glue
22:02and release you in no time.
22:04While hanging up a painting,
22:06it can be impossible
22:07to find that stubborn nail.
22:09Place a fork upside down
22:10and insert it
22:11so the nail is in between
22:13the middle fork teeth.
22:14The fork has provided
22:15a long arm
22:16that's separated from the wall,
22:18making it easier
22:19to slip the string
22:20of the painting over the nail.
22:22Once it's perfectly balanced,
22:24simply remove the fork.
22:27You need to put a cake
22:28into a container,
22:30but taking it out again later
22:31by lifting it up
22:32from the inside
22:33might ruin the cake.
22:34Put the lid upside down
22:36and place the cake on the lid.
22:37The base of the container
22:39is now the lid,
22:40making it much easier
22:41to access slice by slice.
22:45Pour out water more efficiently
22:47from large jugs
22:48and bottles by swirling.
22:49This will make the liquid inside spin,
22:51creating a vortex.
22:53The vortex allows for the air
22:55to flow back into the bottle
22:56as the water pours out,
22:58much faster
22:59than the glugging alternative.
23:02There's an easier
23:03and less messy way
23:04to remove eggshells
23:05from a boiled egg.
23:07Once fully boiled,
23:08crack the shell on both ends
23:09by tapping them.
23:10On one end,
23:11pinch off the shell.
23:13Use the opened end
23:14to blow with your mouth.
23:15The force of air
23:16will push the flesh
23:17and expand the eggshell,
23:18forcing out the egg undamaged.
23:22When the hinges
23:23of your laptop break,
23:25repairing them
23:25can cost up to $300.
23:28A far cheaper fix
23:29is to buy a picture frame
23:30and tape it
23:31to the back of the screen.
23:33You've dropped
23:34a small piece of jewelry
23:35on the floor,
23:36seemingly impossible to find.
23:38Take a stocking
23:39and place it
23:40over the end
23:40of the vacuum hose.
23:41Give the area
23:42a good vacuum
23:43and check the end periodically.
23:45You will eventually
23:45find it sitting
23:46at the end.
23:48You've drilled
23:49a hole in the wall,
23:50but the drill hole
23:50is now too wide.
23:52Remove the screw
23:53and find an object
23:54that is slightly shorter
23:55and thinner.
23:56Pieces of plastic,
23:57small wires,
23:58paper clips,
23:59or even toothpicks
24:00are perfect.
24:01Place whichever item
24:02you find inside the hole.
24:03It's filled the gap enough
24:05so the screw
24:06will now re-enter securely.
24:08Taking the trash out
24:09can put you
24:10in a gross scenario
24:10of getting bin juice
24:12on you.
24:12A great way
24:13to avoid this
24:14is by placing old papers
24:15at the bottom of the bag.
24:17Now,
24:17not only does it absorb
24:19all the liquids
24:20from the food
24:20and other sources,
24:21but also helps prevent
24:23bad smells
24:23from forming
24:24within a bin.
24:25Nobody likes mosquitoes,
24:27and pesticides
24:28are pricey.
24:29A cheap alternative
24:30is to take
24:31a plastic bottle
24:32and cut the top part off
24:33from the bottom
24:34of the funnel.
24:35After removing it,
24:36turn it upside down
24:37and put it
24:38inside the bottle.
24:39Mix two cups
24:40of warm water
24:40with two tablespoons
24:42of sugar.
24:43The mosquitoes
24:43will be attracted
24:44to the formula
24:45inside
24:45and become trapped.
24:47Now just sit back
24:48and relax
24:49without getting bitten.
24:52Okay,
24:53I know it's kind of
24:54cold to the touch,
24:54especially on a freezing
24:55winter's day,
24:56but did you know
24:57that brass doorknobs
24:58actually serve a purpose
24:59apart from looking
25:00classy and shiny?
25:01Since it's a copper alloy,
25:03brass has antimicrobial properties.
25:05That means
25:06it can help get rid
25:07of harmful germs
25:07and bacteria,
25:08sometimes in up to two hours.
25:11In high traffic areas,
25:12that's all the more useful,
25:14but since brass
25:15is much costlier
25:16than other metals
25:16like nickel and steel,
25:17you barely see
25:19these types of doorknobs
25:20anymore nowadays.
25:21Speaking of lovely
25:22multi-purpose items,
25:24most screwdrivers
25:25have a tiny little secret
25:26of their own.
25:27They can sometimes
25:28be slid through a wrench
25:29so that they can be used
25:30to create more torque
25:31when twisting,
25:32not to mention the uses
25:33when it comes to bolts
25:35in hard-to-reach places.
25:37There's a reason
25:38why buttons
25:38on women's shirts
25:39are for the left-handed
25:40and it has nothing
25:42to do with fashion.
25:43This practice
25:44dates back to the times
25:45when chambermaids
25:46were helping ladies
25:47dress themselves
25:47and it was easier
25:49for them to perform
25:50their job
25:50with this orientation.
25:52Having the buttons
25:53placed as such
25:54indicated a sign of wealth,
25:56so it's easy to imagine
25:57why the practice
25:58carried on,
25:59even though most people
26:00dress themselves nowadays.
26:02Next time you receive
26:03a package in your mail,
26:04take a look
26:05at your box cutter.
26:06If it features
26:07some diagonal lines
26:08on the blade,
26:09you're in for a little
26:10design perk.
26:11Turns out that
26:12these are blades
26:12that snap off.
26:14Continuously cutting
26:15cardboard can dull
26:16the sharp edge
26:17of the blade.
26:17To help prevent
26:18the need to buy
26:19a brand new box cutter,
26:20the top segment
26:21along the next line
26:22can be broken off
26:23to reach a new
26:24sharp edge.
26:25To do this,
26:26check out the small hole
26:27at the base of the tool,
26:29sometimes called
26:30the blade snapper.
26:31The people that first
26:32came up with this
26:33brilliant invention
26:34were engineers
26:35inspired by the way
26:36chocolate bars
26:37are segmented.
26:38Hold on a minute,
26:39don't throw away
26:40the cardboard package
26:41just yet.
26:41Most likely,
26:42you'll have some
26:43silica gel packets
26:44somewhere at the bottom
26:45of the box.
26:46Since this gel
26:47is basically a drying tool,
26:48it gathers up the moisture
26:49out of its environment,
26:50so you can store
26:51these packets
26:52for further occasions.
26:53Whether you'll need
26:54to dry out your phone
26:55or some other
26:56electrical object,
26:57you can place them
26:58in a container
26:59next to the silica gel
27:00to reduce the damage.
27:02You don't have to be
27:03a mechanic to know
27:04when a standard car tire
27:05needs replacing,
27:06since they come equipped
27:07with a neat indicator.
27:09Take a closer look,
27:10and you'll see that
27:11treads within the tire
27:12are a bunch of rubber notches.
27:14When the treads
27:15are evened out
27:16with the perpendicular bars,
27:18it's a sign you need
27:19to book an appointment
27:20with your local car service.
27:21Since most likely,
27:23the tires have lost
27:23most of their traction
27:24and may not be safe
27:26for driving any longer.
27:27The upper corners
27:29of a car windshield
27:30feature textured black dots
27:31melted into the glass edges.
27:33This neat add-on
27:34isn't there
27:35for design purposes.
27:37It's called
27:37frit glazing,
27:39which means
27:40that a special type
27:41of ceramic paint
27:42is added to the window
27:43for protecting its sealant
27:45from UV rays.
27:46It also conceals
27:47and creates
27:48a coarser surface
27:49for the adhesive used
27:50to set the window in place.
27:53Whenever you're up
27:54for a drive,
27:55check out
27:56if there's a small tab
27:57under your car's
27:58rearview mirror.
27:59Bet you didn't know
28:00it's there
28:01to help switch the mirror
28:02from daytime
28:02to nighttime views.
28:04It uses
28:05a prismatic glass technology
28:07to blur the reflection
28:08and reduce the glare
28:10of headlights behind you
28:11in traffic.
28:12People came up
28:13with these manually
28:14tilted mirrors
28:15in the 1930s,
28:16but they became
28:17standard somewhere
28:18in the 1970s.
28:20While you're in the car,
28:21check out the headrests,
28:22as you most likely
28:23don't know
28:24that they carry
28:24a little disguised purpose.
28:26Of course,
28:27they're adjustable
28:28to accommodate passengers
28:29of any height
28:30so that they get
28:31the proper support
28:31for their heads and necks.
28:33The hidden feature
28:34is that they are detachable
28:35and come with two
28:36very solid metal bars.
28:39Should you ever
28:40find yourself
28:40stuck in a car
28:41and need to make
28:42a fast getaway?
28:43These bars come in handy
28:45to crack out
28:45the car windows.
28:47So you're out
28:48for a drive
28:48and you're suddenly
28:49out of gas.
28:50What I'm about
28:51to describe
28:52sounds more like
28:52a meme
28:53than an actual
28:53situation bound
28:54to happen.
28:55But what if
28:56you're in such a hurry
28:57that you accidentally
28:58drive off
28:59with the gas nozzle
29:00still in the tank?
29:01Well,
29:02the nozzles
29:03have been designed
29:03to prevent any hazards
29:05from happening,
29:06rest assured.
29:06They feature
29:07a breakaway device
29:08that will allow
29:09the hose to separate
29:10when taken out
29:11with enough force.
29:13Initially designed
29:14in the early 20th century
29:15to be worn exclusively
29:17by basketball players,
29:18sneakers soon became
29:19one of those
29:20fashion fundamentals
29:21similar to jeans
29:22and leather jackets.
29:24If you take
29:24a closer look at them,
29:25you'll see they have
29:26two extra holes
29:27on the side,
29:28similar to the
29:29shoelace holes.
29:30They're manufactured
29:31as such not only
29:32to provide
29:32extra ventilation
29:33but to allow people
29:34to get extra creative
29:36with their laces
29:36when wearing the shoes.
29:38Admit it,
29:39you've always thought
29:40that chopsticks
29:40are merged at the end
29:41for the sole purpose
29:42of keeping them together
29:43until you're ready
29:44to dig into your meal.
29:46That may or may not
29:47be the whole truth.
29:48Under a more detailed
29:50inspection,
29:51the wooden tools
29:51feature a square-shaped end.
29:53Chopsticks manufactured
29:55like this
29:55date back to an
29:56old Japanese
29:57traditional design
29:58which can help
29:59with breaking
29:59the ends easily.
30:00The separated end
30:02can then be used
30:03as a resting block
30:04for the chopsticks
30:05to keep it more sanitized
30:06in hopes it can be used again
30:08since they won't be
30:09touching the table
30:10or any other surface.
30:12Women's bikes
30:13have a special design
30:14which, surprisingly,
30:16has a historical
30:17and fashionable purpose.
30:18The lower frame
30:19is for the most part
30:20meant to make up
30:21for the generally
30:22shorter height of ladies
30:23compared to that
30:24of the average gentleman.
30:26While that is the case
30:27for handlebars
30:28and saddles,
30:29the overall frame
30:30is lower for an
30:31additional purpose.
30:32Way back when women
30:33wore long skirts
30:34and dresses all day,
30:35every day they needed
30:36to make sure their outfits
30:37wouldn't get caught
30:38in the frame.
30:40That's how we came up
30:41with a lower-framed bicycle,
30:42perfectly made for women
30:44and their needs
30:44at the time.
30:46The fact that
30:47toothpastes
30:48are multicolored
30:49is not just a nice perk
30:51to make dental hygiene
30:52more fun.
30:52There's a secret meaning
30:54related to each of the colors,
30:55which dates back
30:56to the 1970s.
30:58In those days,
30:59people grew more
31:00and more interested
31:01in their oral health care
31:02and as such,
31:04they were looking
31:04for products
31:05which could do more
31:06than merely clean
31:07their teeth.
31:08One company
31:09was the pioneer
31:10in that regard,
31:11adding mouthwash
31:12to its toothpaste,
31:13meaning the blue strip.
31:14They later added on
31:15the red strip,
31:16meant to feature ingredients
31:18which helped
31:19with gum care.
31:20Speaking of toothpaste,
31:21check the cap
31:22next time you open
31:23a new tube.
31:24You may be in
31:25for a little surprise.
31:26There's a pointed cone shape
31:28inside the cap
31:28so you can puncture
31:30the seal of the toothpaste
31:31without cutting yourself
31:32or ruining your manicure.
31:34Not to mention,
31:35it's more hygienic
31:35since you won't be able
31:36to transfer germs
31:37or other bacteria
31:39into the product itself.
31:41On the subject
31:42of bathroom countertop items,
31:44toothbrushes come
31:45with a neat add-on
31:46hidden in the bristle patterns.
31:48Apart from making
31:49the toothbrush look cooler,
31:50they also do come
31:51with a practical purpose.
31:53Most toothbrushes
31:54come with a pattern
31:55of blue bristles
31:56intertwined with white ones.
31:58The blue dye
31:59is meant to fade out,
32:00signaling the time
32:01when you need
32:01to replace your toothbrush.
32:04Dentists say
32:04that toothbrushes
32:05should be replaced
32:06every three to four months,
32:08but it does serve
32:08as a great reminder
32:09in case you forget.
32:11Still love playing
32:12with Lego?
32:13Don't judge.
32:14Hey, it's a great hobby
32:15for all ages.
32:16Notice there's a hole
32:17on top of the Lego heads?
32:19Behold, you're looking
32:20at a safety feature
32:21that the people at Lego
32:22designed to prevent
32:24choking hazards.
32:25The most dangerous issue
32:27should a person
32:27swallow any of these pieces
32:29is the blocking
32:29of the airways.
32:31Designing a hole
32:32inside the Lego head
32:33helps the air
32:34to flow freely
32:35through the piece
32:36until it can be
32:37removed safely.
32:38We're now used
32:39to all sorts
32:40of modern light bulbs,
32:41some tubular,
32:42some shaped like diamonds,
32:44and some even twisted
32:45all together.
32:47Historically,
32:47light bulbs were round
32:49and the initial shape
32:50served a purpose
32:51in itself.
32:52It was mainly connected
32:53to the fact
32:54that glass bulbs
32:55were hand-blown,
32:56which gave them
32:56the round shape
32:57to begin with.
32:58The hidden practical reason
33:00was that the light bulb filament
33:01needed to be
33:02at the same distance
33:03from every surface
33:04of the glass sphere.
33:05The easiest way
33:06to achieve this
33:07was to make the glass
33:08in the shape of a globe.
