THE MICROWAVE

In 1946 Percy Spencer, working on the company's radar "Raytheon", saw that the chocolate bar that he had in his pocket was melting while he was in front of a magnetron, a device that converts electrical energy into electric microwaves.

It seems fascinating and he wanted to do a few more tests to understand what had happened. Then he put a pan with an egg and a bowl of popcorn near the generator. After that, Spencer found that the egg was cooked and that the popcorn had popped.

Finally he had discovered that exposure to low intensity microwave heated food. At the last he created the first microwave in the United States and began selling in 1947.
