You can do this at home! Buy a 50 pound bag of popcorn from a Club (Sam's, BJ's, etc) for $12.50. Buy a package of heavy duty 9 inch paper plates. You already have oil, and you have an OXO salad spinner.

Put 3 tablespoons of oil ojn the plate and slosh around. Add just under one cup (either 3/4 or 2/3 if you insist on a measurement). Then put the basket (white, with holes, not the clear plastic bowl) inverted over the plate, unsert in mocrowave and figure out how long you need. Some microwaves take longer-- mine takes 2 min and 35 seconds. Makes a lot of popcorn fast, tastes good, and it's what, almost free compared to the prebagged, pre-additived microwave stuff.

Note: the edges of the paper plate will not be hot when done, but the *bottom* of the plate will be *very* hot, so use due caution.

This is, however, safe enough that I let even my youngest kid do it.
