00:01What's hiding inside Coca-Cola cans and regular household batteries?
00:05Why do magnets affect breakfast cereals?
00:08Do crosswalk buttons actually work or are they just useless decorations?
00:14What does that USB symbol really mean?
00:17I'm not sure I know the answers to these and similar questions,
00:21but I'm eager to learn the truth together with you.
00:24Let's find it out.
00:26Coca-Cola cans have a secret few people know about.
00:30Here's a Coke can.
00:31Let's submerge it in a highly corrosive alkaline solution.
00:35The aluminum dissolves due to a process known as hydrolysis,
00:39and we can see a plastic liner inside the can.
00:42It's made from a polymer or epoxy resin
00:45and serves as some kind of a protective barrier
00:48between the aluminum walls of the can and the rather acidic soda.
00:53Despite a popular myth, household batteries don't actually contain liquid,
00:58and if you accidentally cut them open, no toxic liquid will spill.
01:02Most of them are dry cell batteries which are made of electrochemical cells.
01:06Those convert chemical energy into electrical energy.
01:10Larger batteries often house numerous small cells within them too.
01:14Even Tesla vehicle batteries consist of multiple small cells.
01:18When combined, they easily provide the necessary voltage.
01:24Most toothbrushes have differently colored bristles,
01:27but they aren't just pleasing to the eye.
01:29Those bristles, often blue, have a functional purpose.
01:32They're called toothbrush indicators,
01:34and their colors fade as you use the brush.
01:37The American Dental Association recommends changing your toothbrush
01:40at least four times a year.
01:43And by getting paler,
01:44these bristles help you figure out when it's time to replace your toothbrush.
01:49You'll probably agree that there's no better snack than a pack of chips.
01:53Some are flat, others have ridges.
01:55Is it just aesthetics?
01:57Not really.
01:58The main purpose of those lines on some kinds of chips
02:01is to help with the distribution of spices and seasonings.
02:04In other words,
02:05all those substances that make your chips taste like cheese
02:08are mostly stored inside the lines.
02:11Plus, the lines make chips crunchier.
02:15Now, this one might be a surprise,
02:17but some breakfast cereals are magnetic.
02:19That's because they're often fortified with iron
02:22in the form of a fine powder.
02:24Due to the added iron,
02:26cereal flakes get attracted to magnets.
02:28All this may sound kind of alarming,
02:30but in reality,
02:31the iron content in the flakes is minimal
02:33and doesn't pose any threat to your health.
02:37That clear fluid in gel pens
02:38is called the ink follower or stopper fluid.
02:41The gel in such pens contains pigment particles
02:44dissolved in a polymer solution.
02:47The main task of the stopper fluid
02:49is to be a barrier
02:50to prevent the gel from evaporating or leaking out.
02:53Without this transparent fluid,
02:55your gel pen wouldn't function.
02:58The fluid always stays in one position
03:00and doesn't get dissolved with the gel.
03:02Neither does it move backwards
03:04or flow out of the pen.
03:07Many pedestrian crosswalk buttons,
03:09namely in New York,
03:11are placebo buttons.
03:12They do literally nothing when you press them.
03:15Originally, they were functional
03:17after being introduced in 1964,
03:19but today,
03:20most of them don't affect traffic lights,
03:22which are programmed
03:22based on the real needs of the traffic flow.
03:26Why do such buttons even exist then?
03:28It's a simple psychological trick,
03:30providing you with an illusion of control.
03:34You might have noticed
03:35that movie theater seats
03:36are almost always red.
03:39This choice isn't random.
03:40It has strategic importance,
03:42which is rooted in visual science.
03:44The thing is,
03:46red light has a longer wavelength.
03:47It means that it's the first color
03:49to disappear in low light.
03:51It allows the audience
03:52to concentrate better on the screen
03:53once the movie begins.
03:55Such a design choice
03:56enhances the viewing experience
03:58by minimizing distractions.
04:01Speed bumps are crucial
04:02for pedestrian safety,
04:04but at the same time,
04:05they can seriously increase car emissions
04:07due to the non-stop acceleration
04:09and deceleration they cause.
04:13To address this issue,
04:14some cities like London
04:15are testing fake speed bumps.
04:17Those are optical illusions
04:19painted on the road.
04:20They look raised
04:22from a driver's perspective,
04:23but in reality,
04:24they're flat.
04:25Authorities hope that this approach
04:27will slow down drivers
04:28without having a negative impact
04:30on the environment.
04:33Soda bottles are always filled
04:35in such a way
04:36that there's some space
04:37between the liquid and the cap.
04:39That's because soda contains
04:40carbon dioxide.
04:41It's a gas that can expand
04:43once the bottle's heated.
04:44If there's no gap in the bottle,
04:46it can break
04:47because of the pressure
04:48building inside.
04:50Also, when you open your drink,
04:52the gases go out
04:52in the form of bubbles,
04:54making the drink overflow.
04:55The gap helps
04:57with this problem, too.
05:00The USB symbol,
05:01looking like a trident,
05:03has always sparked
05:04multiple speculations
05:05about its origin.
05:07One popular idea
05:08is that it represents
05:09Neptune's trident
05:11and symbolizes power
05:12and adaptability.
05:13But there's also
05:14a little bit less exciting theory.
05:17A man who claimed
05:18to have designed the symbol
05:19in the 1980s
05:20stated that it was supposed
05:21to represent connectivity.
05:23The large circle
05:24symbolizes a computer,
05:26while the attached shapes
05:27– the circle,
05:28the triangle,
05:29and square –
05:29stand for different outputs.
05:33The design of a tennis racket
05:35has a specific feature
05:36known as the throat.
05:38It's an open space
05:39below the head of the racket.
05:41This space isn't just
05:43for storing balls,
05:44it also improves
05:45the racket's aerodynamics
05:46by letting air pass through.
05:48It seriously reduces drag
05:50during swings.
05:52Speaking of tennis,
05:54tennis courts are usually built
05:55with a north-south orientation.
05:58It helps minimize the impact
05:59of the sun's position
06:00during the game,
06:01ensuring that neither player
06:03has the sun directly
06:04in their eyes.
06:06Look closely
06:07at a tram's overhead lines,
06:09and you'll see
06:10that its contact wires
06:11zigzag back and forth
06:13instead of going
06:13in a straight line.
06:15That's because all trams
06:16have pantographs
06:17attached to their roofs.
06:19The upper part
06:20of the pantograph
06:21is gradually worn down
06:22by the overhead wire
06:23and eventually
06:24needs to be replaced.
06:26To wear it down evenly,
06:28the wire is not installed
06:29strictly along the tram's path,
06:32but in zigzag patterns.
06:34As the tram moves,
06:35the pantograph slides
06:37along the wire,
06:38and it wears down evenly.
06:41Those cone-shaped water cooler cups?
06:44Their shape is intentionally designed
06:46to prevent users
06:47from setting the cups down.
06:48This allows employees
06:50to minimize the risk
06:51of spilling water
06:52on their desks
06:53around various electronic devices.
06:55Plus,
06:56less material is used
06:57to produce cone-shaped cups,
06:58which makes the process
06:59less wasteful
07:00and more cost-effective.
07:02It also kind of supports
07:04sustainability
07:05by encouraging people
07:06to drink their water quickly
07:07and dispose of their cups
07:08immediately after.
07:12Most suitcases
07:13have two zipper pulls,
07:14and it serves
07:15several purposes.
07:17First of all,
07:18if one zipper fails,
07:20the other can keep
07:21the suitcase closed.
07:22Even better,
07:23having two zippers
07:24allows you to have
07:25easier access
07:26to small sections
07:27of your suitcase
07:28without having to
07:29open it entirely.
07:31And finally,
07:32when you have two zippers,
07:34you can connect them
07:35with a padlock
07:35for increased security.
07:39Some plastic milk containers
07:41have dents on their sides.
07:42These dents
07:43serve several purposes.
07:45When milk spoils,
07:46it usually causes swelling
07:48and high-pressure buildup
07:49inside the container.
07:50That's when the dent
07:51pops out
07:52and doesn't let
07:52the jug blow up.
07:54Plus,
07:55if you decide
07:55to freeze the milk,
07:56it will expand
07:57like any other fluid.
07:59And then again,
08:00the indentation
08:01will pop out
08:02and prevent the container
08:03from breaking
08:04inside your freezer.
08:07If you ever had
08:08a problem figuring out
08:09why fake pockets exist,
08:11you need to hear this.
08:13The main reason
08:14is that if a clothing item
08:16has a specific cut
08:17or shape,
08:18pockets may spoil it.
08:19They can alter
08:20the item's shape
08:21either in the warehouse
08:22or already on
08:23the retail rack.
08:24The solution?
08:26Getting rid of the pockets
08:27in key areas.
08:28Plus,
08:29fake pockets
08:30are obviously cheaper
08:31and they don't get
08:32stretched out.
08:34The thermos
08:35wasn't actually invented
08:37to keep your coffee warm.
08:39It was made
08:40by a Scottish scientist
08:41who wanted
08:41a safe place
08:42to keep his chemicals
08:43at a stable temperature.
08:45So,
08:46he took two bottles,
08:47put the smaller one
08:48inside the bigger bottle,
08:49and vacuumed out
08:50the air between them.
08:55You must have noticed
08:57those lines
08:57on some kinds of chips.
08:59For one thing,
09:00they help with the distribution
09:01of spices and seasonings.
09:03In other words,
09:04all those substances
09:05that make your chips
09:06taste like cheese
09:07are mostly stored
09:09inside the lines.
09:11Plus,
09:12the lines make chips
09:13crunchier.
09:15Some cars have a tiny
09:17coffee cup sign
09:18on their dashboard.
09:19It's the vehicle's
09:20anti-drowsiness mechanism.
09:23There are manufacturers
09:24that equip their cars
09:26with a drowsiness
09:27detection system.
09:28It analyzes the speed,
09:30wheel angle,
09:31and lane deviations
09:32to figure out
09:33if it's time for the driver
09:34to take a break.
09:36If it is,
09:37the vehicle makes
09:38several audio signals,
09:39and the coffee cup sign
09:41starts to flash.
09:44Some plastic milk containers
09:46have dents
09:47on their sides.
09:48These dents
09:48serve several purposes.
09:51For one thing,
09:52when milk spoils,
09:54this process
09:54usually causes swelling
09:56and high-pressure buildup
09:57inside the container.
09:59That's when the dent
10:00comes in handy.
10:01It pops out
10:02and doesn't let the jug
10:03blow up.
10:05Plus,
10:06if you decide
10:06to freeze the milk,
10:08it will expand
10:09like any other liquid.
10:10And then again,
10:11the indentation
10:12will pop out
10:13and prevent the container
10:14from breaking
10:15inside your freezer.
10:18You might have wondered
10:19why jerry cans
10:20have three handles.
10:21It's a clever designer move.
10:24This way,
10:25if you carry
10:26the container alone,
10:27you can use
10:28only the central handle
10:30to distribute
10:30the weight evenly.
10:32But,
10:33if your friend
10:33wants to help you out,
10:35each of you
10:35can grab the side handle.
10:38The first jeans
10:39had a problem.
10:41Workers and miners,
10:42who were the original
10:43jeans wearers,
10:44put too much pressure
10:45on the poor piece
10:46of clothing.
10:47As a result,
10:48the seams
10:49couldn't withstand
10:50the stress
10:51and tore.
10:52Tiny metal studs
10:54were invented
10:54to prevent this
10:55from happening.
10:58Sticky notes
10:59come off
10:59relatively easily
11:00because their adhesive
11:01is spread out
11:02across the paper
11:03unevenly
11:04in small blobs.
11:06And only some
11:07of these blobs
11:08touch the surface
11:08of whatever
11:09you've stuck
11:09the note on.
11:11That's why
11:11when you unstick
11:12a post-it
11:13and attach it
11:14to something else,
11:15it still works
11:16until all the glue
11:17gets used
11:18or covered with dirt.
11:21Soda bottles
11:22are always filled
11:23in such a way
11:23that there's some space
11:25between the liquid
11:25and the cap.
11:27That's because
11:28soda contains
11:29carbon dioxide.
11:31It's a gas
11:32that can expand
11:33once a bottle
11:34is heated.
11:34If there's no gap
11:35in the bottle,
11:36it can break
11:37because of the pressure
11:38building inside.
11:40Also,
11:41when you open
11:42your drink,
11:43the gases go out
11:44in the form of bubbles
11:45and the drink
11:46is likely to overflow.
11:48The gap helps
11:49with this problem too.
11:52Dental floss
11:53is super useful
11:54for your teeth,
11:55but it might be
11:56rather hard to operate.
11:57It regularly slips
11:59out of your fingers
11:59and tangles.
12:01To avoid these problems,
12:03tear off a piece
12:04of dental floss
12:05and tie its two ends
12:07together.
12:07It'll be much easier
12:09to use
12:09and won't hurt
12:10your fingers.
12:12Now,
12:13about those horizontal lines
12:15on plastic bottles.
12:17They help hold
12:18bottles up.
12:19Some bottles
12:20are produced
12:21from soft plastic.
12:23Without the lines,
12:23they wouldn't keep
12:24their shape.
12:26Instead,
12:27they would twist
12:27easily
12:28or even break.
12:31The soft,
12:32round part
12:32under a soda bottle cap
12:34keeps the carbonation
12:35from escaping.
12:37Without it,
12:38your pop
12:38would go flat
12:40in no time,
12:41probably even
12:42before you buy it.
12:44If you don't have
12:45anywhere to put
12:46a toothpick
12:46after using it,
12:48break off its flat end
12:49at the first groove
12:50and place it
12:51on the table.
12:52Now,
12:53you can balance
12:54the used portion
12:55of your toothpick
12:55on the grooved part
12:56so that it doesn't
12:57have to touch
12:58the table.
13:00You can also
13:01make a makeshift stand
13:03for disposable chopsticks.
13:05They have a sort
13:05of lump
13:06on one side.
13:07Break that lump off
13:08before you split
13:09the pair.
13:11Now,
13:12when you want
13:13to take a sushi break,
13:14just place the stick
13:15on this stand.
13:18Donuts are shaped
13:19like rings
13:20because,
13:21otherwise,
13:21they might get
13:22overdone at the edges
13:23but uncooked
13:25and gooey inside.
13:27With a hole
13:28in the center,
13:29both the outside
13:30and the inside
13:30get ready
13:31at the same time.
13:34Ever notice
13:35that layer
13:36of clear fluid
13:37in gel pens?
13:38It's called
13:39the ink follower
13:40or stopper fluid.
13:42The gel
13:43in such pens
13:44contains pigment
13:45particles
13:45dissolved
13:46in a polymer solution.
13:48The gel
13:49should be thick enough
13:50to keep the pigment
13:51particles suspended
13:51but also thin enough
13:53to flow first
13:54onto the ball
13:55and then the paper.
13:57The main task
13:59of the stopper fluid
14:00is to be a barrier
14:01to prevent the gel
14:02from evaporating
14:03or leaking out.
14:05Without this
14:05transparent fluid,
14:06your gel pen
14:07wouldn't function.
14:09The fluid always
14:10stays in one position
14:12and doesn't get dissolved
14:13with the gel.
14:14Neither does it
14:15move backward
14:16or flow out
14:17of the pen.
14:19Some button-down shirts
14:20have a button
14:21hidden on the back
14:22of the collar.
14:24Its main purpose
14:25is to prevent the tie
14:26from sticking out
14:27from under the collar.
14:29As for that
14:30locker loop
14:31on the back,
14:33you can use it
14:34to hang the shirt
14:35on a hook
14:35to avoid wrinkling it.
14:38Outer rings
14:39and zipper sliders,
14:41especially when
14:42two sliders
14:42are used together,
14:43are added
14:44so that you can
14:45connect them
14:45with a lock
14:46and keep sticky
14:47fingers away.
14:50Most ambulance cars
14:51have this word
14:52printed on the front
14:53of the vehicle.
14:54That's the word
14:55ambulance backward.
14:58It's written in reverse
14:59so that the driver
15:00in front of the ambulance
15:02can see the word
15:02properly in their
15:03rearview mirror.
15:05Then they can move
15:06out of the way
15:07and let the ambulance
15:08pass.
15:10Escalator brushes
15:11serve an important
15:12safety purpose.
15:14You might have heard
15:15that most accidents
15:16happen after people
15:17get their bags
15:18or clothes stuck
15:19in escalators
15:20because they stand
15:21too close to the sides.
15:23But when there are
15:24nylon brushes
15:25on both sides,
15:26you can't but keep
15:27your feet away
15:28from the escalator's
15:29skirt panels.
15:30The result?
15:31No accidents.
15:34The side holes
15:35in sneakers
15:35are for laces.
15:38Since sneakers
15:39were originally
15:39invented for basketball
15:41players,
15:41this interesting design
15:43allowed them
15:43to accommodate
15:44any player's foot.
15:46They just needed
15:47to lace their sneakers
15:48in the most comfortable
15:49way for them.
15:51The holes in the
15:52bottoms of your earphones
15:54allow air to circulate
15:55up and through
15:56the speakers.
15:58It helps to increase
15:59low frequencies,
16:00making the bass
16:01sound deeper.
16:02The quality of the sound
16:04also becomes much better.
16:07Ever been stranded
16:08with a cup of applesauce
16:09but no spoon at hand?
16:12But each snack pack
16:13already has a built-in spoon.
16:16Several twists of the foil lid
16:18and here you go!
16:22Diamond slits on backpacks
16:24were originally placed
16:25only on traveler bags.
16:27Their purpose was
16:28to carry ropes.
16:30These days,
16:31you can find such slits
16:32on almost every backpack.
16:34Why not use them
16:35to carry a bottle of water,
16:37an umbrella,
16:37or a pair of sneakers?
16:41Highlighters are filled
16:42with a special
16:43semi-transparent fluorescent
16:44ink that can glow
16:46in dim light.
16:48Yellow and light green hues
16:50are the most popular
16:51because they don't prevent
16:52you from seeing the text
16:54after black and white
16:55photocopying.
16:57Photocopiers perceive
16:58yellow and light green marks
17:00as almost non-existent
17:02and don't print them.
17:04A stop sign
17:05has an octagonal shape
17:07to help drivers
17:08recognize it easily,
17:09even if they see it
17:10from the back.
17:11When the signs
17:12weren't reflective yet,
17:14this shape
17:14prevented drivers
17:15from confusing
17:16the stop sign
17:17with any other night.
17:20The number 57
17:21on a Heinz ketchup bottle
17:23has nothing to do
17:24with the product label.
17:26The truth is
17:27that the place
17:28with the numbers
17:28is the very sweet spot
17:30you should tap
17:31to get the ketchup flowing.
17:33So, stop hitting
17:34the bottom of your sauce bottle
17:36and hit 57.
17:39Lots of private houses
17:41have triangular-shaped roofs
17:42because this allows rain,
17:44snow, and fallen leaves
17:46to slide off the slope.
17:48If all this stuff
17:49piled up on top of your house,
17:52one day,
17:52your roof would collapse.
17:56Airplane windows
17:57have rounded edges
17:58and that's a crucial
17:59safety measure.
18:00It prevents
18:01aircraft accidents.
18:03Weak spots
18:04are usually situated
18:05in the corners.
18:07If airplane windows
18:08were square
18:08or rectangular,
18:10each of them
18:10would have
18:11four potential weak spots.
18:13Under pressure,
18:14they would collapse.
18:18Here's how you can
18:19protect your bank card
18:20from potential fraudsters.
18:21Use a marker
18:22and cover the last four digits.
18:24You can also use
18:25a sticker that's easy
18:26to remove
18:27and place it
18:27over the security code.
18:29Have you had a houseguest
18:31that didn't use a coaster?
18:32Get a hairdryer
18:33and hold it a couple of inches
18:34away from the stain.
18:36Blow it on medium heat
18:37for a couple of minutes
18:38to evaporate the watermark.
18:40If a faded ring remains,
18:41mix equal amounts
18:42of vinegar and olive oil
18:44in a bowl.
18:44Wipe it onto the marked area
18:46and rub it in
18:47until the stain disappears.
18:48Then wipe it off.
18:50Don't waste time
18:51scrubbing the burnt stains
18:52off the bottom of a pan.
18:53Instead,
18:54fill it with water
18:55and add three tablespoons
18:56of salt.
18:57Let it sit overnight
18:58as the salt dissolves
19:00the burnt marks.
19:00And in the morning,
19:01pour the water
19:02out of the pan.
19:03This way,
19:04it will be much easier
19:05to scrub all that grease off.
19:07Picture this.
19:08You're on vacation
19:09and your shirt
19:10has become all crinkled
19:11inside the luggage.
19:12You need it tonight,
19:13but the hotel
19:14doesn't have an iron.
19:15Don't panic.
19:16Hang the shirt up
19:17in the bathroom
19:17and while you relax
19:18in a hot shower,
19:20the heat and moisture
19:20will unwrinkle your shirt.
19:22It won't be perfect,
19:23but it will get much better
19:24without any effort.
19:26The football is on
19:27and it turns out
19:28you've run out
19:29of standard batteries.
19:30You can use
19:31a smaller battery instead
19:32that easily fits inside.
19:34Now take some aluminum foil
19:35and crunch it up.
19:37Fit it into the gap
19:38on the negative
19:38or flat end
19:39of the battery.
19:40All done.
19:41You can turn on
19:42the TV now.
19:43Once your flip-flops crack
19:45and the plug easily
19:46slips out of the hole,
19:47it's normally a sign
19:48that you need a new pair,
19:50but there's a way
19:50to extend their mileage.
19:52Push the plug
19:53back through the hole,
19:54then take a bread clip
19:55and attach it to the end.
19:57The clip will provide
19:58enough support
19:59for the plug
19:59to remain in place.
20:01You've received a package
20:02and the receipt
20:03is taped on.
20:04You've managed
20:05to detach it from the box,
20:06but how to separate the tape
20:08without ripping the paper.
20:09Hold both ends
20:10of the tape apart
20:11and by pulling it slowly,
20:13the tape stretches
20:14and separates itself
20:15from the paper
20:16without tearing it apart.
20:19Ziploc bags are perfect
20:20to keep things dry,
20:21but it would be great
20:22if they were larger.
20:24Take two
20:24and turn one of them
20:26inside out.
20:26They can now connect
20:27and work as one large bag,
20:30big enough
20:30to protect a keyboard.
20:32There's no need
20:33to carry your keys
20:34in your hand
20:35when you go for a jog.
20:36Instead,
20:36put them inside your pocket,
20:38take a rubber band,
20:39then tie it around the pocket
20:40from the inside.
20:42This stops the keys
20:43from falling out.
20:45You've broken your key
20:46in the door.
20:47It's stuck.
20:48Great!
20:49Arranging for a locksmith
20:50could cost up to $100,
20:52but for a cheaper
20:53and quicker option,
20:54try using a hot glue stick.
20:56Heat the end
20:56with a lighter
20:57and once it's warm enough
20:58to melt,
20:59push the glue
20:59into the keyhole.
21:01The melted glue
21:02will enter the available space
21:04covering part of the key.
21:05Once it cools,
21:07it compresses
21:07and gains a strong hold
21:09of the key's end.
21:10Now,
21:10just pull it out.
21:13If you need to siphon liquid
21:14through a hose
21:15and want to avoid
21:16using your mouth,
21:17put one end in the liquid
21:18and hold the other upwards
21:19with your thumb
21:20closing the top.
21:21Now shake up and down.
21:23This jiggle motion
21:24pushes liquid upwards
21:25a little each time.
21:27And once it reaches the top,
21:29lower the exit point
21:30and let gravity do the rest.
21:32You've left your keys
21:33locked inside the car.
21:35It's an older model
21:36with a roll-down window.
21:37You could get the coat hanger
21:38and begin the long process
21:40of finding the lock
21:41or use duct tape.
21:42Make about 20
21:43two-foot-long strands.
21:45Stick them onto the window,
21:47allowing enough room
21:48for the tape
21:48to grab onto
21:49at the bottom.
21:50Then with a friend,
21:51take the ends of the tape,
21:52holding them together,
21:53and pull downwards.
21:55The force will allow
21:56the window to lower enough
21:57that you can unlock the door.
21:59While drilling long screws
22:01into hardwood,
22:02your old drill
22:03might not have enough power,
22:04leaving them only halfway in.
22:07Before the drill gives up,
22:08get a block of wax
22:09and scrape the edges
22:10of the screws with it.
22:11The wax works like a lubricant,
22:13melting as it gets warm
22:14and providing easy entry
22:16for the screw.
22:18You're out camping,
22:19but you didn't bring anything
22:20to light the barbecue.
22:21Take a small plastic bag
22:23that won't leak,
22:24fill it up with water
22:25and close it tight,
22:26making a round bubble.
22:27Hold it over where you want
22:29to catch the light
22:30from the sun.
22:31The bag of water will work
22:32like a magnifying glass,
22:34starting up the barbecue,
22:35just as long as it's a sunny day.
22:38Missing a corkscrew
22:39or a cork breaking halfway?
22:41By using a stove lighter,
22:42heat the top of the bottle.
22:44The heat slightly expands the glass,
22:46and this forces the cork
22:47out the top.
22:49You've superglued
22:50your fingers again.
22:51Take some salt
22:52and pour it on top
22:53of your stuck fingers.
22:54Put your fingers into the water
22:56and slowly rub.
22:57The mixture will dissolve the glue
22:59and release you in no time.
23:01While hanging up a painting,
23:02it can be impossible
23:03to find that stubborn nail.
23:05Place a fork upside down
23:07and insert it
23:08so the nail is in between
23:09the middle fork teeth.
23:10The fork has provided
23:12a long arm
23:13that's separated from the wall,
23:14making it easier
23:15to slip the string
23:16of the painting over the nail.
23:18Once it's perfectly balanced,
23:20simply remove the fork.
23:23You need to put a cake
23:25into a container,
23:26but taking it out again later
23:27by lifting it up
23:28from the inside
23:29might ruin the cake.
23:31Put the lid upside down
23:32and place the cake
23:33on the lid.
23:34The base of the container
23:35is now the lid,
23:37making it much easier
23:38to access
23:39slice by slice.
23:41Pour out water
23:42more efficiently
23:43from large jugs
23:44and bottles
23:44by swirling.
23:45This will make
23:46the liquid inside spin,
23:48creating a vortex.
23:49The vortex allows
23:50for the air
23:51to flow back
23:52into the bottle
23:52as the water pours out,
23:54much faster
23:55than the glugging alternative.
23:58There's an easier
23:59and less messy way
24:01to remove eggshells
24:02from a boiled egg.
24:03Once fully boiled,
24:04crack the shell
24:05on both ends
24:06by tapping them.
24:07On one end,
24:08pinch off the shell.
24:09Use the opened end
24:10to blow with your mouth.
24:11The force of air
24:12will push the flesh
24:13and expand the eggshell,
24:15forcing out the egg
24:16undamaged.
24:19When the hinges
24:20of your laptop break,
24:21repairing them
24:22can cost up to $300.
24:24A far cheaper fix
24:25is to buy a picture frame
24:27and tape it
24:27to the back of the screen.
24:29You've dropped
24:30a small piece of jewelry
24:31on the floor,
24:32seemingly impossible to find.
24:35Take a stocking
24:35and place it
24:36over the end
24:36of the vacuum hose.
24:38Give the area
24:38a good vacuum
24:39and check the end
24:40periodically.
24:41You will eventually
24:42find it sitting
24:43at the end.
24:44You've drilled
24:45a hole in the wall,
24:46but the drill hole
24:47is now too wide.
24:48Remove the screw
24:49and find an object
24:50that is slightly shorter
24:51and thinner.
24:52Pieces of plastic,
24:54small wires,
24:55paper clips,
24:55or even toothpicks
24:56are perfect.
24:57Place whichever item
24:58you find inside the hole.
25:00It's filled the gap enough
25:01so the screw
25:02will now re-enter securely.
25:04Taking the trash out
25:05can put you
25:06in a gross scenario
25:07of getting bin juice
25:08on you.
25:09A great way
25:09to avoid this
25:10is by placing old papers
25:11at the bottom of the bag.
25:13Now,
25:14not only does it absorb
25:15all the liquids
25:16from the food
25:17and other sources,
25:18but also helps prevent
25:19bad smells
25:20from forming
25:20within a bin.
25:22Nobody likes mosquitoes
25:23and pesticides
25:24are pricey.
25:25A cheap alternative
25:26is to take
25:27a plastic bottle
25:28and cut the top part off
25:29from the bottom
25:30of the funnel.
25:31After removing it,
25:32turn it upside down
25:33and put it
25:34inside the bottle.
25:35Mix two cups
25:36of warm water
25:37with two tablespoons
25:38of sugar.
25:39The mosquitoes
25:39will be attracted
25:40to the formula
25:41inside
25:42and become trapped.
25:43Now just sit back
25:45and relax
25:45without getting bitten.
25:48Have you ever wondered
25:50what these extra holes
25:51at the top
25:51of your running shoes
25:52are for?
25:53They're designed
25:54so that you can tie
25:55the shoes
25:55in multiple different ways.
25:57That's useful
25:58when you want
25:58to compensate
25:59for things
25:59such as a bad stride
26:01or even a damaged toe.
26:04Plus,
26:05you can change
26:05the look of your shoes
26:06the way you prefer.
26:10Many people use
26:11a dust jacket
26:12of their book
26:13as a bookmarker.
26:14No problem with that.
26:15It will save your book
26:16from bent page corners.
26:17But the primary purpose
26:19of a dust cover
26:20is to keep the book safe
26:21from distortions.
26:23For instance,
26:24if you spill juice
26:25or drop some of the food
26:26on your book
26:26while reading it.
26:29The Tic Tac dispenser
26:30has this little groove
26:31on its top
26:32so you can dispense
26:33only one Tic Tac
26:34at a time.
26:35Even though,
26:36let's be honest here,
26:37nobody does that.
26:39Most of us
26:39just spill a whole bunch
26:40at once
26:41and then we wiggle
26:42all those extra
26:43Tic Tacs back in.
26:46Those rubber bumps
26:47you see between
26:48the tire treads
26:48are there for your safety.
26:50The raised edges
26:51tell you what
26:52the minimum height
26:52of your tread is.
26:54If the bump
26:55and the edges
26:55are even,
26:56it's time for you
26:57to visit the tire shop
26:59as soon as possible.
27:00But if the bumps
27:01are well beneath
27:02the level of the edges,
27:03you're good to go.
27:06What about that black grating
27:07on the microwave window?
27:09It's something called
27:10a Faraday shield
27:11and it's there
27:13to prevent microwaves
27:14from getting away
27:14and turning the entire room
27:16into a Faraday cage.
27:18If the microwaves escape,
27:19your meal won't cook
27:20properly either.
27:22So yep,
27:22the cage is not there
27:24to make it difficult
27:25for you to see your meal
27:25while it's cooking.
27:26It's keeping
27:27the electromagnetic energy
27:28inside.
27:31How about a wrench
27:32compatible screwdriver?
27:34Cover your screwdriver
27:35with the end of your wrench
27:36and you can increase
27:37its torque.
27:38That's why the head
27:39of your screwdriver
27:40is designed
27:41the way it is.
27:42When you have
27:43odd angles,
27:44you can use this strategy.
27:47You've probably
27:47heard those myths
27:48the blue side
27:49of the eraser
27:50can erase the pen.
27:52False.
27:52Its purpose
27:53is to erase a pencil
27:54but in case you're
27:55writing something
27:56on heavier paper.
27:58The blue side
27:59can remove smudges
28:00you see after using
28:01the pink eraser too.
28:04Have you ever wondered
28:05why oranges in supermarkets
28:07mostly come in the red mesh bag?
28:09It's a trick
28:10to make this food
28:11look more orange
28:12and encourage you
28:13to make a purchase.
28:15An extra tip,
28:16don't throw away
28:16the mesh bag.
28:17Tie it up
28:18so you can have
28:18a small pot scrubber
28:20to clean your sink,
28:21kitchen,
28:21appliances,
28:22and dishes.
28:25You can see
28:26golf balls
28:27don't have
28:27a perfectly round shape.
28:29Their surface
28:30is covered
28:30with many little dimples,
28:32something golf balls
28:33didn't always have.
28:34At one point,
28:35experienced golfers
28:36started noticing
28:37how through time,
28:39older balls
28:40with imperfections
28:41such as nicks
28:42and bumps
28:43could travel further.
28:45Such things
28:46create turbulence
28:47in the air
28:47around the golf ball,
28:49which eventually
28:50reduces drag.
28:51So,
28:52manufacturers
28:53started producing
28:54balls with dimples
28:55so they could go
28:55farther and faster.
28:59You might have noticed
29:00that sometimes
29:00there are ridges
29:01in toothpick tops.
29:02It's more hygienic
29:04because when you
29:04break that off,
29:05you can prop
29:06the toothpick up on it
29:07and it won't
29:08touch anything.
29:11Another safety feature
29:12you'll find,
29:13this time in your car,
29:15is a tab
29:15on your rearview mirror.
29:17With it,
29:18you can change
29:18the position
29:19of the mirror
29:20so you don't get
29:21blinded if there's
29:21a car behind you
29:22with its high beams on.
29:24So,
29:25this little tab
29:25helps you control
29:26the glare of lights
29:27coming from behind.
29:28This feature showed up
29:30in the 1930s,
29:31but in the early 1970s,
29:33it became a part
29:34of standard equipment
29:35in most trucks
29:36and cars.
29:38Do you see that
29:39tiny hole
29:40on your iPhone
29:41right next to
29:42the rear-facing camera?
29:43It's a microphone
29:44and it's there
29:45so your phone
29:46can record sound
29:46as you turn
29:47your camera around.
29:51Some cables
29:52have a thick cylinder
29:53towards the end
29:54of the cord.
29:54It's called
29:55a ferrite core
29:56or a choke.
29:58It's a magnetic
29:59iron oxide
29:59that stops
30:00high-frequency
30:01electromagnetic interference.
30:03For example,
30:05you know that
30:05annoying static noise
30:06you get
30:07if you bring your phone
30:08too close to a speaker?
30:09This interrupts
30:10your call,
30:11which is why
30:12cable cords
30:12with big cylinders
30:13are pretty useful
30:14because they
30:15prevent these things.
30:18Do you know
30:19why nearly all
30:20luggage bags
30:20and backpacks
30:21have two zippers?
30:22It's way more
30:23convenient
30:24and easier to open
30:25in that way.
30:26But not just that,
30:27you can also lock
30:28these two zippers
30:29together
30:29to keep the stuff
30:31inside your bags
30:31safer.
30:34You know how
30:35toilets at public
30:36spots like malls
30:37have those big
30:38gaps at the bottom?
30:39It's primarily
30:40for better
30:41circulation of air.
30:42This type of door
30:43also makes it easier
30:44to clean the toilet
30:45or check if it's
30:47occupied
30:47if you're standing
30:48in line.
30:49Other than that,
30:50if you get stuck
30:51there and the lock
30:52gets broken,
30:53you still have a way
30:54to escape.
30:55You can just
30:56crawl out.
30:58Ever notice
30:59those plastic end
31:00caps on utility knives?
31:02And they also
31:03have scales on them,
31:04which indicates
31:06you may use them
31:07multiple times
31:07but with sharp edges.
31:10You can separate
31:11the blades
31:11through these
31:12plastic end caps,
31:13then you can
31:14move the slider
31:15and bring the
31:15sharp blade
31:16to the front.
31:17If you've ever
31:19taken a moment
31:19to examine
31:20a regular grocery
31:21cart,
31:22especially their
31:23fold-out section,
31:24you probably
31:24noticed those
31:25metal loops
31:26jutting out.
31:27They're designed
31:28to protect the
31:29items you carry
31:30in your cart.
31:31You can use them
31:32to hang bags
31:33with soft items.
31:34You don't want
31:36to accidentally
31:36squish with
31:37heavier products
31:37like bread
31:38or easily
31:39breakable things
31:40like eggs.
31:43Many coffee mugs
31:44come with curved
31:45notches on their
31:46bottom.
31:46When you're
31:47washing your mugs,
31:48put them against
31:49the rack at an angle
31:50in your dishwasher.
31:51This way,
31:52the water won't
31:52pool in there,
31:53so your favorite
31:54cup will be
31:55completely dry by
31:55the time you take
31:56it out of the
31:57dishwasher.
31:59If you're a
32:00McFlurry fan,
32:01you've probably
32:02noticed there's a
32:03square hole in the
32:04handle of the spoon.
32:05It's there so you
32:06can attach it to the
32:07special machine that
32:08mixes the ice cream
32:09and your favorite
32:10toppings together.
32:12The machine has a
32:13bar that slips into
32:14this square-shaped
32:15spoon and then
32:16thoroughly stirs it.
32:17And you get the
32:18spoon so they can
32:19minimize the mess
32:20during the process.
32:22Quite neat,
32:23wouldn't you say?
32:25A regular milk jug
32:26has a dent on one
32:28side.
32:29Some might see it
32:30as a random
32:30design decision,
32:31but a dent has
32:32several purposes.
32:34One of them is to
32:35get bigger if there's
32:36a gas buildup.
32:37This happens when
32:38your milk is spoiled.
32:40So you don't even
32:41have to try to
32:42check this out.
32:43Also, the dent is
32:44there so the jug
32:45doesn't burst if you
32:46accidentally drop it.
32:48The dent allows the
32:49expansion space that
32:50deals with the sudden
32:51pressure that happens
32:52when you drop the
32:53jug.
32:55Dental floss.
32:57Sure, it's important
32:58for your dental health
32:59and it's easy to assume
33:00what you do with it.
33:01But dental floss is
33:02great in the kitchen as
33:03well because it's a
33:05very precise cake
33:06slicer, way better
33:08than a regular
33:08night.
33:12Most kitchen shears
33:13have a serrated
33:14opening right there
33:15at the center where
33:16the blades and
33:17handles meet.
33:18It's something you
33:19can use to trim
33:19difficult herbs such
33:21as rosemary, thyme,
33:22or chives.
33:24Because of this
33:24opening, you don't
33:25need to pick the
33:26leaves off by hand,
33:27but de-stem them
33:28in one motion.
33:31The majority of
33:32gelatin containers or
33:33single-serving
33:34yogurts come with a
33:35tinfoil lid, and in
33:37most cases, you can
33:38use this covering as
33:39a disposable spoon.
33:41Just peel away the
33:42covering and after a
33:43couple of simple
33:44folds, you'll have a
33:45perfect little spoon
33:46for your midday snack.
33:47back.
