1. What you didn’t know about Microwave Ovens…

2. History of the Microwave:
Dr. Percy L. Spencer of Massachusetts first experimented with radar in After noticing that a chocolate bar in his pocket melted, he wondered if microwave energy could be used for cooking. He experimented by popping corn with microwave molecules and soon realized the cooking possibilities were endless. He then filed a patent for a microwave oven that very same year. At first, microwave ovens were large and very expensive, but by 1947 they were modified, becoming practical for consumers. Today, microwave ovens are major appliances found in almost every kitchen around the world.
