Gather your supplies and measure out 1 tablespoon of popcorn.
Remove metal caps from the glass ornament balls. Place funnel into opening and pour in the popcorn kernels.
Carefully slide the clear ornament into a brown paper lunch bag, make sure the opening is on top.
Fold the ends of the bag together and place in microwave. Microwave on high for about 1 minute. Listen to when you hear the popcorn popping slow down and turn off the microwave.
Leave the bag with the popcorn ornament in the microwave until it cools down. CAREFUL, it will be very HOT. Then remove and open the bag.
When the glass popcorn ornament is completely cool, turn the glass ball upside down and shake out any unpopped kernels.
Replace the metal cap and your popcorn Christmas ornament is ready to be decorated with a ribbon and hung on your tree.
