Witches Brew Root Beer (Dry Ice)

-Water 10 cups
-Sugar 2 1/2 cups
-Root Beer Extract 2 tablespoons(1 oz.,1/4 of a 4 oz bottle)
up to 4 T(2oz., 1/4 cup, 1/2 a 4 oz. bottle)
-Dry Ice 1 to 3 pounds
Stir water, sugar, and extract.  Carefully add dry ice, either a little at a time or all at once.  Do not close lid, it will explode; but if you cover container 1/2 to 3/4 it will make better bubbles in the soda.  But it is great either way.  Takes dry ice maybe an hour, but you can drink it before if you are careful to not ladel dry ice with the root beer.

Dry Ice:
Do not touch with bare hands, (but do touch it with a thin blade, table knife, it makes a cool screech sound).  You can touch it briefly but any longer skin will freeze, it is almosst 100* below zero.  Wrap closely in a brown paper bag and store in freezer.
Costs just over $1 a pound.  Does not last in freezer (loses 10% a day), so don't buy too much extra. Does not hurt to breath the smoke, just co2, but if you start getting a headache, you are getting too much.  Break apart with hammer if needed.

For 30 Cups (about): 
-Water 32 cups,2 gallons
-Sugar 8 cups 
-Extract 1/4 to 1/2 cup, 1/2 to 1 full 4 oz bottle
