The Accidental Discovery

The microwave oven is a common appliance in kitchens today, but it was invented by accident. In 1945, an American engineer named Percy Spencer was working on a radar set. He had a chocolate bar in his pocket. Suddenly, he realized that the chocolate had melted.

Spencer was surprised and wanted to know why this happened. He tried placing other foods, like popcorn kernels, near the radar equipment. The popcorn popped quickly. He realized that the invisible waves from the radar, called microwaves, were heating the food. He soon built a metal box to hold the waves and created the first microwave oven.

The first microwaves were very large and expensive. They were mostly used in restaurants and on ships. It took many years for the technology to become smaller and cheaper. By the 1970s, microwave ovens began to appear in homes, changing the way people cooked forever.
