Black Grating In The Microwave
Most people have not inspected their microwave too closely, but the feature we are about to highlight is easy to notice. The door of a microwave has a black grating called the Faraday shield, which is actually very important. It stops electromagnetic fields from getting out of the microwave and warming things and people. Such a useful safety feature!

Dimples On Golf Balls
A golf ball is not really round, and it has dimples all over its surface. Apparently, golfers observed that balls with nicks can travel a longer distance. Since the imperfections create turbulence, drag is reduced. They wanted to have more lift so they began making golf balls with dimples. However, if you play putt-putt, it will not help much.
