"Pink and blue ice cream with cotton candy flavors. Very simple to make and fun for the kids on really hot summers. Enjoy! Also there is no extra sugar needed for this recipe; that's what the cotton candy is for!"
Fill one 1/2-gallon-size resealable plastic bag with 1 package cotton candy, 1 cup milk, and 2 teaspoons vanilla extract; seal bag.
Fill one 1-gallon-size resealable plastic bag with 3 cups ice and 3 tablespoons rock salt. Place the sealed bag with cotton candy mixture into the filled 1-gallon bag. Seal the 1-gallon bag; shake until a firm ice cream forms, about 20 minutes. Repeat with remaining ingredients and bags.
