The Justice Pad by Charlie Justice

A 6" x 4", spiral-bound note pad is given to your spectator. While you look away, the spectator writes any number and then tears the page out. The paper is folded several times and the pad is closed. This is all done while you are still looking away. Under these circumstances, with ZERO questions of ANY kind, you can instantly reveal the number, with no re-opening of the pad. The method is just brilliant, - straight out of Charlie's strolling repertoire.
