Shuffle a puzzle cube and announce that it will be a magical prediction. Next, you show a book with dozens of images of various mixed cubes, leaf through it and ask the audience to say "Stop" at any point in the book. Then ask them to choose the illustration on the right or left. When you compare the mixed cube with the illustration, the face of the cube and the chosen illustration match! The artist then solves the cube instantly and, when you look at the book, all the cubes in the illustrations have also been solved!
