Yep, regular yellow popcorn from Walmart. There are 2 main types of corn, Dent corn has a small indention in the ends of the kernels and that is the type that is sweet corn, the kind you roast or buy in a can. Flint corn is the other kind, that kind is left on the stalk until the entire plant dies and dries up, the seeds of flint corn are rounded on the ends and that is the type used for feed, cornmeal and popcorn.
Different varieties have different properties, but generally a dent corn is meant to be harvested at the "milk stage" and eaten wet (rather than dried), flint can generally be popped but some varieties will pop better than others.
