Aldo Colombini brings you an incredible card routine in three phases.
Heavy Traffic – You place a prediction face down between two face-down Jacks. The prediction disappears. You try again placing the prediction face up between the two face-down Jacks and the prediction card vanishes once again. You place an :invisible” prediction between the two Jacks. A spectator chooses a card, say the 7D. The Jacks are fanned and the invisible prediction has become visible. It is indeed the 7D!
