Interesting facts about the microwave.

In 1946, engineer Percy Spencer, who worked at Raytheon Corporation, experimented with a magnetron tube. And suddenly he saw that the candy in his pocket had melted! This surprised him, and he continued experimenting with products by placing a magnetron in a metal box. Electromagnetic waves of small length (12 cm) cannot pass through metal and are absorbed by products, causing the latter to heat up.
