Place 15-25 kernels of microwavable popcorn in the ornament. (Wipe off some of the oily gunk first).
Place the ornament in a paper bag and put in the microwave for 1-2 minutes.
Listen carefully, you may not need to leave them in for a full two minutes. When the popcorn is done popping, remove the ornament carefully, it will be hot.
Sprinkle some glitter in if you like.
Tie a pretty ribbon on the top and hand from your tree.
