The microwave was invented after a researcher was working near a radar tube and a chocolate bar melted in his pocket
.
It was during a radar-related research project around 1946 that Dr. Percy Spencer, a self-taught engineer, noticed something very unusual. He was testing a new vacuum tube called a magnetron when he discovered that the candy bar in his pocket had melted. This intrigued him, so he tried another experiment. This time he placed some popcorn kernels near the tube and, perhaps standing a little farther away, he watched with an inventive sparkle in his eye as the popcorn sputtered, cracked and popped all over his lab.
Next, he put the magnetron tube near an egg. Spencer was joined by a curious colleague, and they both watched as the egg began to tremor and quake. The rapid temperature rise within the egg was causing tremendous internal pressure. The curious colleague moved in for a closer look just as the egg exploded and splattered hot yoke all over his amazed face.
