Popcorn and the Ideal Gas Law, PV = nRT — The Science of Popcorn!

Did you know popcorn pops at roughly nine times atmospheric pressure? The inside of a popcorn kernel is about ~13% water. When that water heats up—trapped inside the confined space of the kernel’s pericarp—the pressure goes up until the pericarp ruptures and the insides, now melted, spew out.
