When nuking food was novel

1946: Raytheon demonstrates its Radarange, the world's first commercial microwave "stove." This prototype (labeled "Raydarange") was intended for sandwich shops, where it would feed radiation from a water-cooled magnetron tube into a small external container to cook a presumably lousy hamburger in 35 seconds flat. The first consumer microwave wouldn't go on sale until 1955. Users' initial disappointment with rubbery chicken turned to delight once they discovered the joys of nuking popcorn, Hot Pockets, and marshmallow Peeps.
