The magician shows a square plastic tube, explaining that it contains six dice; five white and one red. Another set of five white dice are placed on the table in a row and another red die is handed to a spectator, who is asked to place it anywhere between the white dice. The dice inside the tube are now slipped out onto the table alongside the other dice. To everyone's surprise the position of the red (prediction) die matches exactly with the position of the of the red die placed by the spectator!

Easy to do! Can be repeated.

Great close-up commercial mentalism!
