1 gallon cold water ▢2 – 2½ cups sugar ▢3 tablespoons root beer extract, zatarain brand ▢1½ – 2 pounds dry ice, broken into pieces
Add water and sugar to a large punch bowl, stirring to dissolve sugar completely.
Add root beer extract and stir to combine. Taste and add any more sugar or extract needed.
Make sure you are mixing the root beer in a well-ventilated area.
Carefully split up the dry ice into little pieces. Using gloves or tongs, add the dry ice pieces to the water, sugar, and extract mixture, stirring to prevent the ice from sticking to the bowl and melting the dry ice. The mixture will begin to bubble, and fog will pour out and over the bowl.
Make sure ice is completely melted before ladling into cups or mugs. To be extra safe, you can pour the mixture through a mesh strainer before stirring to filter out any small pieces of dry ice.
