Ordinary corn kernels can not do popcorn, do it yourself at home, it fried paste can not be popped, can only be used on the street shaking the handle, there is pressure of the kind of popcorn popping machine. Like the sound of a cannon.

Now supermarkets have bulk popping corn for sale, particles smaller than our common more, a little conical, as if five or six dollars a pound. I often make my own popcorn at home to eat, it's easy, and crackling, it's fun. (*^__^*) hee hee ......

Sending you a picture of the corn to look at.
