Fill champagne flutes with champagne. Right before you are about to serve the cocktails, add a small ball of cotton candy on top of each glass. Make sure the cotton candy does not touch the champagne, otherwise it will melt. The cotton candy will lose it's fluffiness with time, so make sure not to add it too early.
