Microwave Oven

Do you think mistakes are good? Some mistakes are. One man made a mistake that is good for all of us.

One day a man was working in a lab. His name was Percy Spencer. He had a candy bar in his pocket. He was studying tubes. The tubes were vacuum tubes. He was studying microwaves in the tubes.

The chocolate bar melted, and it got all over in his pocket. The microwaves in the tubes had made the candy melt.

Percy started to think and think. He worked with the waves. He tried many things. They all worked. These microwaves cooked food faster than an oven.

I am glad his candy bar melted in his pocket that day. Now, we can all use the microwave oven. It can cook our food fast!
