Root Beer (idea)

This is a pretty simple recipe I use for parties.
You will need the following items:

• A 5-gallon beverage drum w/ spigot
• A 5 lb bag of white sugar
• A largish bottle of Root Beer Extract
• 4.5 gallons of water
• 5-10 lbs of dry ice
• A Really Big Spoon

Mix the water and sugar together in the drum, and then stir in the flavoring with the Really Big Spoon. Once everything is well mixed, drop in the dry ice and quickly screw on the drum lid. Have someone sit or stand on the lid for about 45 minutes, and then tap the root beer and enjoy.
