You get a Timex Travel Alarm Clock that folds like a cell phone. You show the spectator that when you push the hour and minute buttons, the time changes. You then show him that the cover of the clock closes and that the buttons can be pressed through a hole in the cover. You then ask the spectator to press the buttons with the cover closed so that you or the spectator will not know where the time will stop. When the spectator is satisfied, she is to open the cover and concentrate on the time that she stopped at. You then proceed to read her mind and tell her exactly what time she is thinking of. It then can be repeated with a different outcome every time.
