Homemade Root Beer Float
- 1 gallon carbonated water
- 2 1/2 cups sugar
- 2 teaspoons root beer concentrate
- 1 pound broken dry ice
- Vanilla ice cream, for serving
Combine the carbonated water, sugar and root beer concentrate in an extra-large bowl or punch bowl - something that is food-safe and won't break when the dry ice is added. Don't cover with a lid. Gently stir until the sugar is dissolved. Add the dry ice to the mixture in a well-ventilated area. The mixture will start to bubble. Let the mixture sit for 15 minutes to fully carbonate.
