FOOL-HER is another version of the classic 21 card trick.
This is a version of the 21-card effect that you can share with your fellow magicians.
This is certainly a routine indicated to fool magicians because at each step it eliminates every possible explanation one by one.
Unlike the classic effect, there is no need to ask the spectator which row the card is in.
