Why microwaves were first used
The first microwave used was during World War 2. Scientists invented the magnetron, a tube to produce a microwave.
Magnetron's were installed in Britain's radar system and the microwaves were able to spot Nazi warplanes on their way to bomb the British Isles.
Several years later, Percy LeBaron Spencer found microwaves were also used to cook food.
The first microwave was almost 6 ft. tall
and weighed 750 pounds. and cost
about $5,000, each, called the Radar Range.
The microwave was only used in restaurants
because of it being sd heavy. It helped the
restaurants have fresher food, less waste, and
money saved.

Improved Microwaves
A few years later, the first counter top home microwave was introduced, which cost just under $500 and was smaller, safer, and more reliable than
microwaves before.
America's cooking habits then
drastically changed
by 1976 and became a necessity for
everyone's household.
