Black Grating In The Microwave
We are pretty sure you have never inspected your microwave closely, but the black grating found on its door is quite easy to notice. Called the Faraday shield, it keeps the electromagnetic fields inside the microwave and prevents them from warming people. Without it, heating food would be dangerous.

Dimples On Golf Balls
If you take a closer look at golf balls, you will notice that they are not really round and have dimples all over their surface. Apparently, golfers in the past noticed balls which have nicks and bumps usually travel a longer distance. Since the imperfections create turbulence, there is a reduction in drag. This is why they started making golf balls with dimples in order to create more lift. However, it won’t be of much help if you are just playing putt-putt.
