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.

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.

9. Bumps on the “F” and “J” keys of keyboard

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.
