In the 1940s, Mr.Percy Percy, an expert in radar tube designing was standing in front of an active radar set. After some time he noticed that the chocolate in his pocket got melted up. So he wanted to know how it happened. He created a high-density electromagnetic field in a metal box and observed that the items are getting heated up. Basing on this observation he designed the microwave oven. Now it has become a common item in almost all kitchens mainly in cities and where both wife and husband are employed.
