The History of the Microwave:

by wikipedia

“The heating effect of microwaves was discovered in 1945 by…Percy Spencer, an American self-taught engineer from Howland, Maine…He was working on an active radar set when he noticed that a peanut chocolate bar he had in his pocket started to melt. The radar had melted his chocolate bar with microwaves.

…The first food to be deliberately cooked with Spencer’s microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters.

Since then, the Microwave Oven has become an important part of pop culture. In television shows like “The Office” and “Arrested Development,” starting a fire in a microwave has become a symbol of a character’s idiocy.

My cousin Evan is the lamest superhero in the world. He stood in front of the open door of an old microwave. Now, he gets a splitting headache just before the phone rings. Siiick superpower.

Words of Wisdom.


“i think you should include lifting the stigma of putting metal in the microwave. it’s basically safe. as long as it doesn’t touch the sides.”

    I guess I should modify this by saying: the reason metal sparks in the microwave is because it creates shocks between different parts of the metal. For example, a fork might react by sparks flying between the prongs, but a spoon is one, solid piece, so it won’t do anything. You can put a metal bowl in the microwave, but the metal blocks the microwaves from heating the food. It’s kind of like a magic trick if you think about it.

    Burning a CD in the microwave creates a spiral of sparks. You must shut it off immediately afterwards or you will break the microwave.
