You show four cards with red dots and four cards with yellow dots. When you touch the pack of red dots with the pack of yellow dots one of the red dot cards changes to a yellow dot card. You do this several times until all four cards you are holding have turned yellow. Suddenly they turn back to showing red dots. When you show the pack of yellow cards on the table they now all have blue dots.
