An ingenious piece of equipment, the CocktailMaster allows anyone to start making their own layered cocktails. Using a clever float that sits on your drink as you make it, you can easily pour one drink on top of another without the layers mixing! It's easy to use the CocktailMaster. Simply pour your first liquid into a glass, then place the CocktailMaster on top of the glass with the ball floating on the first liquid. Add the different liquids, one at a time, to the CocktailMaster. If you follow the rules of density stated in the supplied leaflet, you'll be creating layered cocktail concoctions in no time! Please Note: The float must be clean and free of traces of fat or oil.
