Corn kernels contain a small drop of water that is stored inside a circle of soft starch. The soft starch is surrounded by the kernel’s hard outer surface. As the kernel heats up, the water begins to expand, and pressure builds against the hard starch. When this hard surface gives way, the popcorn explodes. As it explodes, the soft starch inside the popcorn inflates and bursts, turning the kernel inside out.
