This is an ok effect on it's one, but it is obvious to most people that the red-tipped wand is
involved and people want to see your hands immediately.
I use this with the PK ring;
1. Show the chinese coin, turn it over and place it in the spectator's hand ((first effect-
chinese coin changes to quarter).
1. Slap their hand with the PK hand which takes off the
quarter shell (second effect- quarter disappears and chinese coin is back).
3. Then hand
out the chinese coin for examination, and stick the quarter shell in your back pocket.
