How? -Spencer was working on building magnetrons for radar sets, he was standing in front of an active radar set when he noticed the candy bar he had melted.
It wasn’t until 1967 that the first microwave oven that was both relatively affordable ($495) and reasonably sized (counter-top model) became available.
Percy Lebaron Spencer was an American physicist and inventor.
He became known as the inventor of the microwave oven.
How? -Spencer was working on building magnetrons for radar sets, he was standing in front of an active radar set when he noticed the candy bar he had melted.
He investigated the radar, tried heating items and similar heating effect could be observed.
The first one he heated intentionally was popcorn kernels, which became the world’s first microwaved popcorn.
Spencer then decided to try to heat an egg, The result was that the egg exploding in the face of one of his co-workers who was looking in the kettle.
Spencer then created the first true microwave oven by attaching a high density electromagnetic field generator to an enclosed metal box.
This first commercially produced microwave oven was about 6 feet tall and weighed around 750 pounds.
The price tag on these units was about $5000 a piece.
It wasn’t until 1967 that the first microwave oven that was both relatively affordable ($495) and reasonably sized (counter-top model) became available.
