The First Microwave Oven Was Huge
In 1945 engineer Percy Spencer noticed a chocolate bar melted in his pocket while he worked near radar equipment. This observation led to the creation of the first commercial microwave oven, which stood nearly six feet tall and weighed over 700 pounds. Early models were used mainly in restaurants and on ships.
💡 Fun detail:
The original microwave could cook a potato in 60 seconds but cost as much as a small car.
