Line 2 12-muffin muffin pans by placing a sheet of plastic wrap over the pan and pushing down into the cups slightly.
Over barely simmering water melt the chopped chocolate, stirring occasionally. Remove from the heat and carefully stir in the popcorn carefully to coat it evenly with melted chocolate. Working quickly, take off large spoonfuls of coated popcorn and form into a loose ball the size of a golf ball. Place it in the cup of the lined muffin pans to rest and sprinkle with the colored sprinkles. Insert a lollipop stick in the bottom and let it set up. To hasten the set-up, place them in the refrigerator. These can be wrapped in colored cellophane with twisted ends. Store at room temperature.
