In 1945, Percy Spencer, an engineer working for Raytheon, was testing a magnetron, the power tube in radar systems. While standing in front of the active magnetron, he noticed that a chocolate bar in his pocket had melted. This observation led him to experiment with popcorn kernels and an egg, which exploded. Following this discovery, he developed the first microwave oven.
Wow, talk about a sweet accident! Percy Spencer's melted chocolate bar was a total game-changer. It's crazy to think that one little mishap led to the invention of the microwave oven we all use today.
