Shell made from stainless steel and other metal materials for microwave ovens, can stop the microwave from the furnace out, so as not to affect people's health. Food containers made with insulating material. Heart is the magnetron for microwave ovens.

This invisible microwave can penetrate food 5cm deep and the water molecules in food also sports, vigorous exercise produces a lot of heat, so the food "cooking" by heart.
