- [Narrator] The internet
is chalk full of pictures and if current trends continue,
there will be 657 billion more of them 12 months from now. Most of them, however, are
not worth the buffering time. But some of them are definitely
worth taking a look at. Join me as we take a look
at 20 images that will make you say, "I had no idea!" (playful music)
- Amazing! - [Narrator] Number
20: Apple's headphones. Must earbuds have two or three holes. The big ones for the noise, and a teeny-tiny one for the microphone. Apple earbuds, on the other hand, look like the work of a
Swiss cheese manufacturer. Don't be too quick to judge. Apple did not do this to save a few bucks. These extra holes actually
reduce the pressure that builds up in
run-of-the-mill headphones. By letting fresh air in
and pressurized air out, these holes improve acoustics. So, next time you get Rick Rolled, make the most of it with a
pair of Apple's headphones. Number 19 - The iPhone Clock App. Now let's talk about the iPhone Clock App. We wager it's one of the first things you shove in a dusty folder
and leave there to rot. What do you need it for when there's a clock
right on your home screen? But, in your haste to declutter, you missed something pretty cool. Unlike other app icons
that are stationary images, that little icon is actually
a working timepiece. If you sit and stare long enough, you'll start to see its hands move. Don't stare too long, though! It's supposed to tell
the time, not waste it. Number 18: The USB logo. Easy to corrupt and one sharp
tug away from snapping in two, most people would not
associate the USB with a god of unimaginable power. Or, since water ruins them, the sea. But, that's exactly
where the icon came from! It is actually based
on Poseidon's trident. The trident has triangles
on all three prongs, but the icon has a circle
and square on two of 'em. You ask, "Why the trident and
not some other pointy object?" The alteration was made to
give a sense of universality and to signify all the
different peripherals that could be attached using the standard. Number 17: The Dairy Queen lid. Why do cold things hate us so much? Poles get stuck to our tongues. Ice rinks like to watch
us crack our skulls open. Even Dairy Queen sundaes turn
our fingers into icicles. That's just the price you pay
for ice cream though, right? Well, It doesn't have to be. You see that lid? It also doubles as an ice cream holder. Just pop off that DQ lid and slide it over the
bottom of your sundae. Number 16: Ketchup containers. What were the manufacturers thinking? These cups are barely big
enough to dip your fingers in, much less a hamburger. That's only because you've
been using them wrong. These little cups are actually a piece of industrial origami. Just grab the outer edge
and tug to fan pygmy cups into the miniature plates
they were meant to be! You are now a condiment master! Number 15: The power button's shape. Take a look at the power button on a nearby electronic device. Go ahead, I'll wait. You ever wonder why it looks like that? As long it wasn't some alien
device, the symbol you saw is a combination of the
universal symbol for on, which is a line, and the
universal symbol for off, which is a circle. Using these icons, in
place of on or off allowed electronic manufacturers to
bypass language barriers. The Bluetooth logo, on the other hand, did not come from some boring handbook. Nope! It's actually the name of
a Viking peacemaker king Harald Bluetooth, written
in Scandinavian runes. Hope that fact didn't rune your day. Number 14: The direction
of your fuel arrows. Have you ever pulled up at a gas station and realized that your gas
cap is on the other side? Do you remember taking the walk of shame back to the driver's side
to turn the car around? As you flipped it into gear, you just knew your ancestors
were shaking their head at you. But, what if I told you there
was a way to tell which side the gas tank is on without
getting out of the car? Take a look at your gas gauge. Do you see that little icon on the dash? The one with the miniature gas pump? Bet you didn't notice that
little arrow next to it. Next time you go to pull up at the pump, make sure its pointing
towards the gas pump. Number 13: Pen cap holes. Kids will stick anything in
their mouth if given a chance. That's why toy companies
like to print those choking-hazard labels on
pretty much everything. So it may come as no surprise
that before the hole was added to pen caps, pens caused over
100 choking deaths a year. That hole in the pen cap is so much more than a
quirky design feature. It's a way to keep kids
from choking on it, leaving just enough space
for them to breathe through should the cap get stuck in their throat. Number 12: Airplane window holes. Is that hole proof of a gremlin at work? A potentially fatal oversight in the design of your jumbo jet? It's actually a pressure regulator. Known as breather holes,
these tiny holes regulate the pressure passing between the
window's outer and inner panes. By ensuring that the outer
pane bears the most stress, these holes ensure you'll
still be able to breathe in case of a window failure. They also keep the window from fogging up to ensure you get a magnificent
view of the ground below. Number 11: Pygmy jean pockets. They aren't big enough for
credit cards, lip balms, or Lilliputians. So, why the heck do jeans have them? People have wondered what
these little holes were for since the invention of jeans. While many have speculated as to what that little pocket is for, the real reason has to do with 19th century cowboys. Back then, cowboys would
string their watches on chains to keep them from falling into a cow pie or braining a grumpy rattlesnake. Tailors added this pocket
to give those cowpokes a place to store their pocket watch. Number 10: Converse holes. A lot of people have
fallen victim to wet feet thanks to these holes. Who the heck thought it was a
good idea to put them there? Converse, of course. Those holes actually improve ventilation. And stop your feet from smelling like an artisanal mix of
bleu cheese and toe jam. They also make it easy
to bar lace your shoes. This special type of
lacing ensures that those Chuck Taylor Converses
don't end up flopping around like cheap rubber clown shoes. Just remember, that next time
you go singing in the rain, these holes are not waterproof. Number Nine: Measuring tape edge. This one takes a keen eye to
notice, but the serrated edge of measuring tape is there for a reason. No pencil handy? No problem! Just scratch the surface you're measuring with the jagged edge to mark your spot. That's just one secret of
this multiple faceted tool. That little hole at the end
can also be hooked over a nail or to hold it in place
when you're measuring. Number eight: Pot handle holes. While every Italian grandma can tell you what the holes in pot handles are for, you might not know. That hole is the perfect
shape and size to hold the end of a spoon when
you're not stirring with it. This helps keep pasta sauce
and chili off your counter and makes cleaning-up a lot easier. Or, if you want to be boring, you can just use them to hang it up. Number seven: Tic Tac lids. Tic Tac has thought of everything! Not only are these
little candies addicting, the container is also handy! Before seeing that picture,
you likely played a game of candy roulette every time
you opened a box of Tic Tacs. You shook the box and hoped
to end up with one mint, instead of twenty. Number six: The 57 on a bottle of Heinz. Heinz today makes more than
5700 distinct products. So, why does the bottle say 57? It all started in 1896
when founder H.J. Heinz stumbled upon an advertisement
for "21 styles of shoes." After some debate, he came up
with the slogan "57 Varieties" despite the fact that the
company offered more than 60 products at the time. The lucky number has
been there ever since. It's put in that specific
location on the bottle for a reason as well. The 57 is placed on the bottle
neck as the best spot to tap in order to get sauce out
quicker, and more efficiently. Number five: Take out containers. Surprise, surprise! It turns out that condiment cups are not the only origami
containers out there. Like its cousin the condiment cup, the typical Chinese takeout
box also unfolds into a plate. Save yourself a few dishes, avoid the grease stains, and chow down! Number four: Airport runway numbers. Every runway in the world
has two numbers on it. But, what the heck do they mean? They don't seem to follow any pattern. Well, it turns out that these
numbers are what keeps pilots from mixing up takeoff
and landing runways. Each number matches a
direction on the compass and sits somewhere between 1 and 36. And each number corresponds
to a point on the compass between 1 and 360 degrees. Every runway number differs from the other by exactly 18, or 180 degrees. This makes it easy for pilots to decide which runway is made for landing. Number three: Reversed military flags. Americans are real sticklers
when it comes to our flag. They have dozens, if
not hundreds of rules, about how to use it,
fly it, and retire it. For example, it's the only
flag that does not tip towards the head of state of the
host country at the Olympics. It must always face forward. Which means the stars sit on the left when its flown on a flagpole. But, on military uniforms, it's flipped. The stars are on the right. The reason why is simple:
the flag cannot be in retreat when the soldier marches forward. Just another sign that
America takes that flag very seriously. Number two: Fire casts no shadow. Take a look at this picture. Do you notice something missing? That's right, there's no shadow. And, no, that's not Peter Pan's candle. You also won't be able
to sew one on with thread or rub it on with a bar of soap. To understand why, you
need to know two things: One: Shadows are the result of light being blocked by an object. And two: A flame is nothing more than a gaseous chemical reaction. Since light can pass
through a flame unaltered, and the flame itself
projecting light onto the wall, there's usually no way
for it to cast a shadow. Number one: Maple syrup handles. Have you ever held a bottle
of 100-percent real maple syrup, or helped smuggle one
across the Canadian border? If you have, you've likely noticed those tiny little teacup handles. It might be large enough
to fit your pinky through but it's not exactly made for pouring. Where did it come from though? And, why is it there? This tiny handle hails from
the days when maple syrup was packaged in a five-gallon jug. As the bottles shrank, so did the handles. But, in order to keep some
of that old-world charm, the handles never disappeared entirely. Which one surprised you the most? Do you have any photos
to share that left you shaking your head in disbelief? Let me know in the comments below! Thanks for watching! (playful music)
