Last year was my first year doing this and it was super exciting. Or not "super", but I was amazed that it actually worked!
First you take popping corn, the yellow ears in the photo above, not the multi-colored Indian corn, which is apparently only for show. Sidenote- Then why is it corn? Why can't we eat it? Who invented this idea?
Ok, I'm back.
Next you let your corn dry out, maybe a few weeks to a month.
Then you put it in a paper bag, fold over the end, and put it in the microwave.
Let it pop until the popping slows (about 2 minutes) or until you smell burning. In which case, toss the bag and corn and start again.
Think of this as a neat party trick, or something to entertain your kids on a cool/wet/drizzly/sick autumn afternoon:)
