The folklore of some Native American tribes told of spirits who lived inside each kernel of popcorn. Once the pressure gets high enough and the temperature reaches about 180 degrees Celsius (355 degrees Fahrenheit), the kernel hull bursts and the popcorn is turned inside out. Endothermic and exothermic heat transfer methods are used to transfer energy. Sorghum, quinoa, millet, and amaranth grain all puff up when heated as the pressure from expanding steam breaks open the seed coat. Microwave ovens are extremely quick and efficient, and they use heat energy directly to molecules (tiny particles) within the food they heat. dextrose is responsible for the sweet flavor and pop that popcorn provides.
