Popcorn (also known as popped corn, popcorns, or pop-corn) is a type of corn kernel that expands and puffs up when heated; the same names apply to the meal that results from the expansion.

The sturdy hull of a popcorn kernel holds the seed’s hard, starchy shell endosperm, which contains 14–20 percent moisture and turns to steam when cooked. The hull ruptures when the pressure from the steam builds, enabling the kernel to violently expand to 20 to 50 times its original volume and then cool.
