SHAMROCK CUP Half | Chazpro Magic Jamy Ian; York A bold method for aEffect : With the Shamrock Cup, coins disappear and appear. There is no end to the possibilities. Coins disappear one at a time or 2, 3 or 4. Coins travel from one location to another. This item is a creative and novel variation on the coin cup. The cup allows the performer to dump out 1, 2, 3 or four coins, depending on how the cup is turned over. Coins magically fly out of and back into the cup, disappear, or appear.
