The sudden appearance of a filled champagne glass is a completely baffling effect. There's a downside though; it can be a pain to carry the hidden glass without spilling the liquid, or somehow covering up the top of the glass.
Wolfgang Moser has come up with an exceptional gimmick that allows for a secure and astonishing production of a glass of liquid. It's an incredibly well made gimmick that allows you to produce any glass with a stem from under a silk, or perhaps from an examined envelope (ala Eugene Burger). Toastmaster is an astonishing effect that will get gasps!
