#4 Microwave Oven

Accident causer: Percy Lebaron Spencer

In today’s fast-paced life when it comes to food, many people go for instant dishes that can be readied in two minutes. The term “instant food” would not have come into existence without those little box containers perched on the kitchen counter that goes by the name microwave ovens. In 1945, Percy Lebaron Spencer, an engineer at Raytheon was working with magnetrons and these devices radiated microwave signals used in earlier radar system. One fine day, in the middle of a lab experiment, Spencer noticed a melted candy bar inside his pockets. He realized that it was the microwaves emitted by magnetron that caused candy bar to melt. Soon he built a box container inside which microwaves were emitted and various eatables were tested for the effect. He doesn’t know he had invented a savoring machine that took off burden from many house wives and bachelors alike.
