Directions for making Homemade Rootbeer:
Stir one and a quarter tablespoons of rootbeer flavor/extract and one cup of sugar into a half gallon of water in a large mixing bowl or pot.
Add one pound of dry ice. The dry ice will bubble and produce fog, giving a "witches' cauldron" effect. After the dry ice is completely gone your rootbeer will be well carbonated.
Kids have alot of fun with this one!
