How a Microwave works ?

We use Microwaves to heat up the food. 

Microwaves are in visible waves that excites the water molecules which heats up the food !


Excites means when water molecules jiggles or shake they rub with each other and get hot. 

Microwaves are not harmful waves like X-rays and gamma rays.

The scientist from America who accidentally discovered the waves during the world war 2  when chocolate in his pocket melted during the experiment  (YUCK!!!!)

When he put corns next to the microwaves the corns POPPED !!!!

When he put the egg next to the microwaves it blasted !!!

This is how he got the idea of microwaves.
