Popcorn!
I learned how to microwave popcorn! No... not throwing one of those packages into the microwave. I mean real popcorn! I put 1/3 cup of kernels into a brown paper lunch bag and folded down the top a few times. I closed the bag with a piece of tape and stood it up in the microwave. In about 2:30 (ymmv), I had real popcorn without that chemical tingle on my lips. Considering there's no oil involved, I may even be able to recycle the bag when it's done.
Healthier... cheaper... I might not bother to replace my busted popcorn popper.
