How the Microwave Was Invented

The microwave oven was discovered by accident.
In 1945, engineer Percy Spencer was working with radar equipment called magnetrons.
He noticed a chocolate bar in his pocket had melted.
Microwaves caused water molecules in the food to vibrate, generating heat.
He tested this further with popcorn and eggs.
Then built a metal enclosure to contain the waves safely.
This became the first microwave oven.
It shows how unexpected observations can lead to major inventions.
