When the sealed kernal of popcorn is heated, the tiny drop of water inside boils and changes from a liquid to a gas, which takes up a lot more space and the kernal actually explodes .Popcorn is a specific variety of corn grown for the reason that it will explode because the water drop is sealed in.

When the water in the kernel flashes into steam explosively, the kernel is, near enough, turned inside out.

...a "phase change" of water to steam and the kernal explodes from the sudden pressure increase.
