How popcorn POPS

Popcorn is a special type of corn, and it is the only variety that pops. Inside each seed is a tiny droplet of water and oil. When popcorn is heated between 350-400 degrees F, the water and oil inside the seed turns to steam, causing it to expand and eventually break the seed coat—the outer hull— open.  When it breaks, or “pops,” the seed is flipped inside out, exposing the soft white fluffy starch.
