Hey, @beeyou and @coruscate,
I've read about how the chemicals in the pre-prepared popcorn bags are really bad for you, so I haven't had that in a while. However, there's a really easy way to make your own if you've got that craving.
Just get un-popped kernels from the store. Put approximately 1/4 cup in a paper lunch bag. Fold the top over and tape it with scotch tape (just so the popped kernels don't get out). Microwave approximately 2 minutes.
Then you just pour in a bowl and add butter and/or other seasoning!
