Here is one recipe for Homemade Root Beer
5 gallons water
5 pounds sugar
5 pounds dry ice
1 bottle of root beer extract (McCormick's is 2oz and seems to be pretty popular)
EDIT: I started using 4 # sugar and 4 gal water (Sugar now cones in 4# bags)
Using a 5 gallon plastic container or some other safe container, pour in about 3 or 4 gallons of water, 5 pounds of sugar, and the bottle of extract. Stir this around to make sure the sugar is distributed. Add the dry ice and let bubble like mad while you enjoy the fog. I tipped my 5 gallon water container with the spout side up to it wouldn't freeze in the spout. After the bubbles slow down, add the rest of the water. That's it! Enjoy.
