Did you know that the microwave was discovered by accident? Percy Spencer, an American engineer was working with magnetrons to create an efficient microwave radio signal when he noticed that the chocolate bar he was saving in his pocket had melted. He connected the melting of the bar to the machine, so he decided to test his theory by putting popcorn in front of the device. When he turned it on, the popcorn popped and he came up with (to create) the idea for a microwave.
Thanks to Spencer, we can warm up our food quickly!
