How the microwave was invented The microwave oven is of the all-time great accidental discoveries of science. In the 1940s, American engineer Percy Spencer was working at Raytheon Technologies testing an active radar while he had a chocolate bar in his pocket. At some point, he noticed that the chocolate had melted into his pocket. Rather than merely changing his trousers, he realised the potential to heat food using a high-density electromagnetic field (and presumably also changed his trousers). He first experimented by getting a bag of popcorn, and attempting to heat that. It worked. He pushed his luck and tried to heat an egg, which exploded spectacularly, thus also inventing the don t put an egg in the microwave rule. Spencer next worked on putting magnetrons (which create microwave radiation) inside a Faraday cage (which blocks electromagne
