The magician enters the stage holding two silks, one in each hand.  He shows the silks, one at a time, displaying them to show that they conceal nothing.  Suddenly, a bottle of wine (or champagne!...) appears between the silks. He immediately hands everything to be examined. His hands are empty!

You receive a new and very clever gimmick that will do the production and will leave you clean after the effect.  Instructions and all silks are included.  Everything can be handed out for examination if you would like.
