Potato chips were invented in 1853 by George Crum. Crum experimented with wafer thin slices of potato when a customer repeatedly refused to eat his fries, because they were too thick and soggy.
Dr. Harry Coover accidently created a substance known as 'cyanoacrylate'. According to him it was a miserable failure. As at that time he was working to make a precision gun sight.

Microwave radiations were discovered by Percy L. Spencer in 1945. He was walking past a radiation tube and noticed that the chocolate bar in his pocket melted.
