Invisible Cocktail (Gimmick and Online Instructions) by Wayne Dobson and Alan Wong

INVISIBLE COCKTAILS is the sort of item that you can carry with you at all times, so you are always ready to perform a natural- looking, powerful routine after hours with attractive, natural props.

It uses an ingenious principle that, for whatever reason, has seemingly been overlooked by magicians.

Wayne took the principle and added the all-important commercial angle of linking it with the sort of cocktail menu you'd find standing in a contemporary bar, hotel or restaurant. It lists many different cocktails, from which the spectator freely chooses one; there is no mathematical force involved, it really is a free selection.

With no funny business, mnemonics, arithmetic, fishing or questioning, the performer is immediately able to name the cocktail they are merely thinking of!

The joy of this routine is that it is super-simple to perform thanks to Wayne's superior routining - it almost justifies being called self-working.
