Oil and water are mixed with starch in the kernels of popcorn, which are hard coated with starch. The best way to obtain air popcorn is to purchase an air popcorn popper. When heated, the water inside the kernel turns to steam and builds up pressure. The cracked kernels produce much smaller flakes because when you damage the kernels outer hull, the water vapor that is created during heating can easily escape through the crack. Radiation popcorn is a popular snack food in many parts of the world and is often sold in vending machines and convenience stores. During this process, the kernels emit micro-waving vibrations that cause the molecules in the water to vibrate. "By looking at the footage and using a microphone to capture the pops, the team found that the pop sounds didn't happen when the hull first split.
