A kernel of popcorn contains a small amount of water and when heated the popcorn pops. How can you explain this to someone

When you put a popcorn kernel in a microwave, the microwave heats up the water. The water then evaporates, and the air wants to escape. There will be so much pressure that the skin/shell of the kernel will break, exposing the corn.
