Using
a food processor, crush chocolate cookies until it looks like dirt.
If you do not have a food processor, place cookies in a zip lock bag
and seal, making sure there is no air left in the bag. Crush with
a rolling pin. Fill each cup about ¼ of the way with the crushed
cookies. Place one or two gummy worms in the glass. Continue adding
small amounts of crushed cookie, then gummy worms until the glass
is full. To cover, use colored saran wrap and tie off with a rubber
band, yarn, string, etc.
