Homemade Root Beer

5 lbs. Sugar
5 gallons water
5 lbs dry ice
1 bottle root beer extract

Dissolve sugar in hot water. Add the rest of the water and the other ingredients. Use a large container (more than 5 gallons). Use the lid to keep fizz in. You need to let the dry ice carbonate the root beer (let sit for at least ½ hour-1 hour).
