The Microwave Oven History

How the microwave oven was discovered?

Mr. Spencer conducted researches with a high frequency generator (about 60,000 MHz) to be used as a radar.

After a while he was a little hungry and decided to eat the chocolate bar that it had been in the pocket of his jacket. When he tried to took out the chocolate bar, he found a melted chocolate.

What happened?

Mr. Spencer decided to verify his experience by placing an egg and some popcorn near the frequency generator and he left the place. When he returned to his lab, he founded that there was popcorn and scrambled eggs all over the place.

The first microwave ovens were commercialized in 1947. These ovens were very large and they were bought by some restaurants only. Since the 70’s, some smaller and cheaper microwave ovens appeared in the market, becoming really popular.

In 1947 a bar of melted chocolate, turned a radar into the first microwave oven.
