Performer places a silver coloured disk in a frame with a cut-out which they can see right through. The disk is placed in the frame, and the silver colour of the disk can be seen both front and back. With a snap of his fingers the magician instantly and visibly causes the disk to change colour. The disk is removed from the frame, now in an entirely different colour. This is repeated with two other silver disks which are visibly changed to two other colours. You can refer to the disks as Compact Disks or CDs which are very popular today. This effect is similar to the Colour Changing Records, but works on a different principle. The more compact size enables you to handle the change in a snappy and effective manner.
