Popcorn is cooked with convection. When popping corn, it is best to use a method that evenly heats up the kernels rather than rapidly or slowly. Microwaves work by causing water molecules to vibrate, which in turn produces heat. When popcorn is heated, the water inside the kernel tries to expand into steam, but it cannot escape through the seed coat (the popcorn hull or pericarp).
