That reminds me of a story about microwaves. The invention of microwave in itself is pretty interesting. It was in 1947 when an engineer was working with military radars and he found out that the electromagnetic radiation from the magnetron was capable of melting a chocolate bar in his pocket and could be used to heat stuff up. They called it "diathermic heating". It wasn't until later though that these things were commercially introduced as what we use in our kitchen today, largely due to magnetron technology developing a bit and becoming more compact. That was in the 1960s.
But before finding their place in the kitchen of an average household, these little boxes were used in something a bit crazier than warming food. In the 1950s, a team of scientists were doing some experiments in the lab of a medical institute where they would freeze hamsters and then try to wake them up by applying heat in different methods. The whole thing wasn't very successful as you would expect but then one of them had this idea of using the same diathermic heating from a magnetron. They actually put frozen hamsters in microwaves and the little guys would start walking after some time. Now of course it doesn't work with larger animals for a few reasons, it's still fascinating.
In conclusion, before their current purpose of heating up your coffee for the third time after you forget to drink it, microwaves were being used to reanimate hamsters. Just a little thing to remember next time you go to the kitchen
