Ingredients
Instructions
Sugar,
according to bottle directions
Recommended amount of water, chilled with ice
1 bottle root beer concentrate
3 lb. dry ice
1 clean bucket with tight fitting cover
Dry ice is EXTREMELY cold and can damage skin
Mix
sugar and water in bucket; add concentrate.
Add dry ice, and sit on the bucket--you may want to release the
pressure every now and then.
In about 15 minutes, you have really fizzy root beer.
If you don't release the pressure every now and
then, it may try to blow the top off! (We use it in high school
physics or chemistry, often with the change-of-state lab involving ice
cream.)
