Black Grating In The Microwave
It is doubtful that you have ever taken a very close look at your microwave. However, you do not need to get all up-close and personal with it to notice the black grating of the door. This is called the Faraday shield. It prevents the escape of electromagnetic fields in the microwave so that you can be safe! Just know that you would not only be in danger without it but your food wouldn’t get cooked either.

Dimples On Golf Balls
The truth is that golf balls are not round. A closer look will be all you need to know to get acquainted with all those dimples on their surfaces. Golfers have noticed that old balls, those with bumps and nicks, happen to travel longer distances. These imperfections create turbulence and reduce drag. You now know why they began to add dimples to ball designs! It’s not going to be helpful with putt-putt, though.
