Microwave Ovens

In 1946 Raytheon engineer Percy Spencer was testing a magnetron a device that emits microwave radiation when he realized that the candy bar in his pocket had melted. He figured the magnetron caused this to happen and tested his theory by placing popcorn kernels near the device. When those popped, he tried to cook an egg, which exploded. Sure, it made a mess, but he also realized that exposure to low-density microwave energy could quickly cook food. Spencer and other engineers started to work on a practical way to trap the waves and use them for this purpose. By 1947 the first commercial units became available through Raytheon. They weighed as much as 750 pounds and cost thousands of dollars, but by 1975 technological advances had made the device as popular (and affordable) as an oven range.
