5. The Microwave
If you’ve ever used a microwave then you have Percy Spencer, a Navy radar specialist, to thank. The first microwave was sold in 1946 under the name “Radarange”. During the accidental developmental process of creating the microwave oven, Spencer spent many days in the lab messing around with microwave emitters trying to improve the power levels in radar sets. One day, when he was adjusting the microwaves he decided to have a snack, and when he reached in his pocket, he was struck with surprise. The peanut cluster bar that he had in his pocket had melted from the microwaves in the lab and it was then he realized what was happening. He continued to test his new creation with various foods and the rest is history.
