Your microwave heats food by shaking water - Video

Your microwave heats food by shaking water.

Inside is a magnetron, making microwaves at two point four five gigahertz. The waves bounce around the metal box. Water molecules have a positive end and a negative end. The electric field flips billions of times a second, and the molecules twist to follow it. All that jostling turns into heat. The turntable spins your food through the hot and cold spots.
