This magical disappearing drink / cocktail is so cool and perfect for any party gatherings. It can be fun and entertaining for all of your guests. What you will need are just cotton candies and Perrier. You can use non-alcoholic Perrier for under-ages, or alcoholic champagne for adults.
Here is how it works. Fill the glass with cotton candies, pour the drink on top, and watch the magic happens as the cotton candies melt and spread through the bubbles.
