6. Microwave Oven
In 1945, while working on radar technology at Raytheon, engineer Percy Spencer noticed that a chocolate bar in his pocket had melted. Curious, he experimented by placing popcorn kernels near the radar equipment, observing them popping. Further testing with an egg resulted in it exploding, confirming that microwaves could cook food rapidly. Spencer and his team developed the first microwave oven, the “Radarange,” which was introduced commercially in 1947. This innovation revolutionized cooking by providing a quick and convenient method to heat food (popularmechanics.com).
