The magician shows three silver compact discs (CDs) and an empty CD sleeve or cover with a hole in the middle.
The audience can see right through, and examine the cover and there is nothing concealed in his. Displaying the first silver CD on both sides, the magician places it in the empty cover. A red ribbon is passed through the hole in the cover and CD, and when the CD is puled out it is seen to have changed to red.
This is repeated with the other two silver CDs, changing them to yellow and green respectively.
This is a modern version of the classic Color Changing Records, made with real CDs (not imitations). Comes to you complete with all required CDs, CD sleeve, ribbons, and full instructions.
