From Dave Powell:
A small chalkboard, divided into six sections is shown sitting on an elegant stand which also rests a piece of chalk. The magician lifts it off the stand and writes a predication onto the first section and covers it with a small flap. He then asks an audience member to shout out any number. He then writes this number in the section below. Next, the magician writes another prediction in the top center section and again covers it. He now asks someone to name any color and writes it in bottom section.
Last, magician writes a playing card in final top section and covers it. He then riffles through a deck of cards and asks the spectator to remember one. The name of that card is written in the final square. The magician reiterates what just happened, 3 separate predictions and 3 separate thoughts. He then hands the chalkboard to the spectator who removes the flaps himself revealing that all three predictions match perfectly.
