A great one by Thomas Pohle. There were versions by others, notably Willi Wessel, Alan Warner and Magic Wagon. The Thomas Pohle version can be looked at all around, it is super easy to do!
Four cubes are shown each with four different digits from 0-9 on the sides. A simple hollow stand is also shown to support the cubes and a prediction, that is yet to be revealed. The magician asks the spectator to hand any cube to him and choose where he would like it placed and what digit should be facing front. This is done for each cube one by one. When the spectator has finished choosing the final cube, the magician slowly reveals the prediction – every number is matches correctly.
