- La la la la la.
Oh, hey, welcome back.
So in life, there are many things that we use
on a daily basis that we just get used to using
and don't really ever think twice about.
Like this pen, for example.
There couldn't be anything secret with
such a simple item, right?
Wrong.
What if I told you that many of the objects
that you use every single day actually hold secrets
that are hiding in plain sight?
Things that you always knew were there,
but you never stopped to question why they exist.
Well today I'm going to reveal the things you never knew
about the most common objects that you use every day.
So sit back and relax.
I'm about to flip your whole world upside down,
because here are 10 things you didn't know
about everyday objects.
Number one is soda can tabs.
Have you ever noticed the hole that exists
on the back end of a soda can tab?
Have you ever wondered what it's there for?
Some people think that it's there to give you
a better grip when you're opening the can,
but it's not.
As it turns out, it's actually there to hold a straw.
After opening your next can of Coke,
spin the tab around to cover the mouth of the can
and put a straw through the hole.
It actually holds the straw in place
and prevents it from moving around on you.
Believe me, this is extremely useful on a date situation.
Oh hey girl, what's up?
Number two is the blue part of erasers.
By now, you've seen those erasers that have pink on one side
and blue on the other.
The pink side obviously is for erasing pencil marks.
But what's the blue side for?
Some people think it's there to give you a better grip
or to erase pen marks.
But neither of those are the case.
The grittier, harder side is actually there for,
well, to erase pencil marks,
but it's not for the way you think.
It's intended to erase pencil marks on coarser paper.
See, the pink side will shred much quicker
on rougher surfaces, so the tougher side was added
to make the eraser last longer and to get darker marks out
on thicker paper.
Number three are pen caps.
Very few of us have ever given much thought
to the design of a pen, I mean,
it seems pretty straightforward, right?
Well one part of it that hides a secret feature
is the pen cap.
Many people think that pen caps are for keeping the pen
from drying out, but if that's true,
why is there a little hole at the top of it?
Well the reason for the hole in the top of the pen cap
is to actually save your life.
See, many people chew on pens while they work,
and it was quickly discovered that the cap
is a major choking hazard.
Thus, to reduce the risk of you choking to death,
a little hole was added to allow air to pass through
in the event of accidental swallowing.
It's literally there so you don't asphyxiate
if you accidentally down that plastic cap
that you chew on.
Man, this assignment.
(gasps)
It's okay, there's a hole in the cap.
Number four is Chinese food containers.
Okay, here's one that's really going to shock you.
How many times have you ordered Chinese food
and just thrown away the box?
Well guess what, you're doing it wrong.
Those oyster box takeout containers actually double
as a plate.
That's right, you've been doing dishes for nothing.
Next time you order Chinese food, don't dirty any plates.
Instead, try this.
Pull the box tabs apart and slowly flatten it.
Once it's flattened, you'll notice that you have
more than enough room to fit the food
that was contained within it on it.
And the best part is, when you're done,
you just throw it away.
Easy.
Number five is the loop on the back of dress shirts.
Here's another little something that you've seen
100 times but never thought twice about.
For decades, men's shirts have been made with
a little something extra that has
never really been explained.
I'm talking about the little loop of material
on the top back of every dress shirt.
It seemingly holds no purpose, or does it?
Well it's actually there as an optional way
to hang your shirt without wrinkling it.
See the loop was originally added in the 1960s
to dress shirts for east coast sailors who used the loop
to hand their shirts while changing.
What was called locker hoops caught on in fashion
when they reached ivy league schools
and it remains to this day.
Number six is the hole in an airplane window.
If you have ever been on a plane and had a window seat,
you might have noticed a tiny, perfectly circular hole
in the glass.
Now if it's your first time flying,
that might have caused you a little bit of panic.
There's a hole in the window!
We all gonna die!
Well, that is until you notice that they're in every window
and yes, they're there for a good reason.
The windows of a plane in fact aren't
actually made of glass, they're made of resin,
and despite how they look, are actually three panes thick.
That little hole actually helps regulate pressure
between the outside pane and the inside pane.
It specifically helps to maintain the stronger
outer window pane, which takes most of the force.
Without it, the pressure over time may actually
weaken the resin, which could become very dangerous.
And ain't nobody got time to be sucked out
of a plane window, you know what I'm saying?
People's busy.
Number seven is the little pocket inside your jeans.
Ever wondered why you've got an extra pocket
inside the bigger pocket of your jeans
that seems like it's just too small to really be of any use?
Well what it's used for today is not what it was
originally used for.
See back in the 1800s, when jeans were invented for cowboys,
they were called watch pockets to hold, well,
you probably guessed it, pocket watches.
Over time, the pockets simply stayed there
for fashion purposes, but it can still be used today
for many things.
Since being a watch pocket, it's been called
the frontier pocket, the condom pocket, coin pocket,
match pocket, ticket pocket, among many other things.
Basically it's there to hold fragile things
to avoid getting them damaged by running them
against something hard in your pocket
like your key or anything else.
Number eight is toothpaste colour codes.
It's likely by now that you've seen a
small colored rectangle on the bottom
of your tube of toothpaste.
Now there is a very popular myth out there
that many people still believe that says that
it's used to identify what the toothpaste inside
is made out of.
The myth is this, is that if the rectangle is green,
it's all natural.
If it's red, it means that some chemicals were used,
and if it's black it means it's 100% a chemical compound.
However, that's not true.
Well the truth is, is that those little rectangles,
which are actually called eye marks, are used to help
electronic equipment determine where the tube ends
so that they know where to cut.
It's actually there to be seen by the eye
of the manufacturing machine as it cuts plastic
into the size needed to form the tube.
Number nine is the dimple in the bottom of the wine bottle.
If you've ever held a wine bottle, you'll notice that
many of them aren't flat but instead have
a pushed in bottom.
Originally, wine bottles were glass-blown containers
that required the dimple, also known as a punt,
on the bottom of it in order to stand up.
Without it, the glass would often form a point
which obviously cannot stand up right.
But today, it actually serves two purposes:
one is that it gives you a place to hold the wine
while you're pouring it, and secondly, in the case of
sparkling wine, it actually helps to spread out
the pressure in the bottle.
And number 10 is the raised bars on the side of tires.
This one could literally save your life,
or at least stop you from breaking the law.
You may have noticed raised bars on the side of your tires,
but likely never gave much thought to it.
Well, you guessed it, they're there for a very good reason.
When tire treads wear down, the odds of hydroplaning,
skidding out or even something puncturing the tire
dramatically increases.
Those tiny raised bars along the tire's grooves
show the minimum thickness or depth that your treads require
and if those little bars become worn,
you know that you've worn out your tires
beyond what's legal.
Many places require you to actually replace your tires
at that point, at like I said, it's illegal in many places
to drive on such a worn out rubber
because replacing them will obviously decrease your chances
of an accident.
So, those were 10 things you didn't know about
every day objects.
