Best Answer

Steam pressure builds in the interior of the kernel until a breaking point occurs in the kernel's shell. Because so much pressure has built up, the interior explodes through the shell and is instantly filled with air, thus its puffiness. The trick is to find the right thickness of the shell, humidity, heat, etc to allow for the largest popped corn.

How do you get the dry kernels off the cob for popcorn?

Shelling corn is when you harvest the corn seeds, that is, the kernals. This is the same idea as shelling peas. (Shucking corn is what you do when you take the husk off the corn ears. ) First, you have to have corn that is specifically grown for pop corn. Not just any corn will do. Get you corn ears and arrange: a pile of corn ears with leaves removed (shucked), a bowl for the kernels, a dust bin for the empty cobs. Start at one end of the ear, but feel around find and easy place where the kernels are so dried up they WANT to come off. With both hands gripping the ear, twist your hands in opposite directions. Twist mightily until you get a start. Once you have some kernels off it's easier to keep going. Keep twisting the cob in your hands until you have all the good kernels off. Some are probably too small and will make for an unsatisfactory pop. One cob five inches long could provide 1/2 cup or so of kernels.
