The Invention of the Microwave
Did you know that the first microwave oven weighed about 772 pounds and was 6 feet tall?
It cost about $5,000.
Now, that is a big piece of equipment.
Microwaves were used the key component for a device called a magnetron, for airborne radar and was helpful during war.
Percy LeBaron Spencer was walking near the magnetron one day and the chocolate bar in his pocket melted.
This gave him the idea to try to use microwaves to cook food.
On October 8 1945, Spencer filed a patent for a "method of treating foodstuffs".
His wish for this patent was successful.
The first prototype microwave oven was installed in a restaurant in Boston the following year.
This was successful and the first commercial microwave oven was produced in 1947, known as the Raytheon.
