Top 10 Best Accidental Scientific Discoveries and Inventions

The Microwave

In 1945 Percy Spencer, an American engineer, noticed one day that the candy bar in his pocket melted while standing in front of an active radar set where he was building magnetrons. He then experimented with popcorn kernels and more. He patented the first microwave cooking oven, named Radarange.


Swedish chemist and engineer Alfred Nobel, who created the Nobel Peace Prize, accidentally discovered dynamite in 1867 while working with nitroglycerin, a highly unstable explosive. He realized that if it were combined with a substance like kieselguhr, it stabilized the explosive and made it safer to work with.
