###The Melted Chocolate and the Microwave
Massachusetts, USA, 1945 — While testing military radar equipment, an engineer noticed his pocket snack melting and accidentally invented a revolutionary way to cook.
In 1945, engineer Percy Spencer was working in a Massachusetts laboratory, testing a powerful vacuum tube called a magnetron. The device was meant for World War II radar systems. But as Spencer stood near the active machine, he noticed his pants were getting awfully gooey.
Reaching into his pocket, he discovered his peanut-cluster chocolate bar had completely melted. Because there was no flame or traditional heating coil nearby, Spencer realized the invisible electromagnetic waves from the radar equipment were creating heat. Intrigued, he grabbed more snacks.
He held un-popped popcorn kernels near the magnetron, watching them pop and scatter across the floor. Next, he placed a raw egg inside a kettle and blasted it with microwaves. The egg violently exploded from internal pressure, and microwave cooking was born.
