Dr. Percy Spencer, invented the first microwave, sort of by accident. He was testing a new vacuum tube (magnetron), and noticed his candy bar melted. He put some popcorn around later, and soon, popcorn popped all over his lab.
After that, he got a raw egg, then placed it near the magnetron. The rapid increase of temperature caused the egg to be cooked inside out. The egg exploded.
He invented the first microwave oven.
