If you look at some of the older posts here, this topic comes up every month or so. Well, maybe not popping it in a dry pan, but the question about popping with no oil.
Many (like myself) use a brown paper lunch bag in the microwave oven. I have an air popper, but it's loud and at the end the popcorn flies around the room. My cats like that part, but I don't.
Others prefer their air poppers.
