Color Changing CDs by Vincenzo Di Fatta

Show a compact disc and put it inside a case with a hole in its center. Take a red ribbon and pass it through the hole and... incredibly the CD turns red! The effect is repeated two more times with other CDs and other colored ribbons and each time the CDs change color!
• The discs used are real CDs.

• At the beginning and at the end of the routine, the case can be shown to be empty.
