Oddball by Royal Magic
The magician shows his audience a solid wooden ball, a clear plastic case and two cords. The cords are threaded through a hole in the ball, which is placed inside of the case. The cords are then threaded through holes in the sides of the case. The magician then ties the participant's finger to the case with the cords.
The audience then watches as the cords visibly penetrate the ball, case and the finger!
The props supplied do all the work for you. No sleight of hand required. No complicated gimmicks to break, no complicated moves to remember.
