This is the WINE version.
A “magical taste test.” The performer shows identical glasses of cola on one side of two large plaques. The opposite sides show a can of Coke and a can of Pepsi. The plaques are slowly mixed. Spectators should be able to keep track of which is which, but every time they guess, they are wrong. Finally, the Pepsi plaque is set aside. The remaining one is Coke, right? No, it is turned over to show a picture of a big bottle of wine! And, when it is turned around again, the brown cola in the glass has changed to wine red! Also in orange juice for children’s shows. Specially gimmicked plaques make it easy to do.
