Grasp a whole ear of corn in your hand, and pull back all the green husks and silk.
Tie a 12-inch piece of twine around the end of the corn, and hang the corn up so it can air-dry. Allow the corn to dry completely until it is hard.
Take down the corn, and hold it over a bowl.
Twist the corn back and forth in your hands, which will cause the corn kernels to pull out from the cob and fall into the bowl. Pick off any remaining corn seeds with your fingers, and drop them into the bowl.
