Once in a blue moon we all must have wondered why there are so many holes here in a single headphone. Let’s take an example of Apple earphone, you must have noticed that it has three holes, one hole is for the speaker and why the others too? Well Apple has explained that they allow passing a small amount of air through which the diaphragm of speaker moves back and forth. It enables the frequent transmission which results in better sound quality.

3. Tabs on Tin Foil

Half of my life I was in the state of oblivion how come I was so blind then for every moment when tin foil used to fall or the cling wrap used to fall. If you will read the instructions carefully it will tell you on the packaging at each end there will be a triangular mark which you need to press, they actually hold your Foil in place.

4. The blue side of eraser

Since childhood, I have been fooling myself. Only god Knows how many pages I have ruined thinking this would work. Never knew that the blue part of eraser has always been for which we used to write on the wall or on any hard surface, and the red one was for which we used to write on paper. Now I know this important piece of information I will defiantly pass on this to the coming generation.

5. Black hole between flash and camera

That probably hardly dragged anyone’s attention about the tiny hole between the camera and the flash. Actually, the tiny hole is a microphone which record the ambient noise, not your voice, because when we take a picture our positioning is pretty far from the mouth during that time. It digitally reduces the ambient noise from the main microphone, which gives pretty clear voice on the other side.

6. Little pockets on your jeans

Still I wonder why I mean why oh! But I like the style! Well to know the reason let’s sneak into the 19th century where the gold miners or the cowboys from the west used to keep their small things like the watch. That was when the jeans were first invented.

7. Hole in pen caps

Well honestly I never bothered about the hole in the cap, but my friends used to make their own assumptions that hole is there for air passage to keep the pencil drying out but the real reason behind this is different. If a child accidentally swallows the cap, this hole helps in lowering the danger of suffocation as it helps to pass the air.

You must have noticed the cylinder wrapped around the charging cord of your laptop. And do you why is it for? The little cylinder part is actually called ferrite bead, and plays an important role in keeping your laptop running. Every small parts inside a laptop run because of radio frequencies. The charging cable acts as antennae, broadcasting your laptop’s vibrations as radio frequencies and picking up signals which creates interference. The cylinder has chunks of magnetic iron oxide which stops the radio frequencies from interfering with each other.

If you notice a keyboard closely you will notice bumps on the ‘F’ and ‘J’ keys. Do you why is it so? The bumps help you to type effortlessly without having the need to see the keys. When you place your index finger of your left hand of the ‘F’ key, you can cover ‘A’, ‘S’ and ‘D’ keys with the other three fingers. Similarly for the right hand. While thumbs of both hands rest on the space bar. This placement helps a typist to know which key is in which direction from the ‘F’ and ‘J’ keys. This enables them to type without looking at the keyboard and also increase the typing speed.

10. Loop on the back of a shirt

We have all seen the loop at the back of shirt, but probably not given it too much thought. Back in the days when there were no wardrobes, these loops were used to hang a shirt without getting wrinkles on it. But nowadays after arrival of wardrobes and lockers these loops serve like a decorative design.

The holes in your Converse actually have two very specific purpose. The first is to provide a little ventilation to your feet (when you are not wearing socks) as the holes allow air to circulate around. And the second purpose is for bar lacing, this allows your shoes to be tighter around your feet.

The tiny holes are for two reasons. One is to compensate air pressure as when the airplane climbs to high altitude there is huge pressure difference between the inside and the outside of the plane. The hole regulates that difference. The second reason is that it prevents the windows from fogging up.
