The performer displays a black (approx. 18″ silk), printed with a design in white, (like a photograph negative). The silk is displayed clearly and completely on both sides, stretched flat between the hands.
He now asks a volunteer spectator, (the Birthday child, for the Happy Birthday Silk design) to toss up some colored confetti into the air, to help color the silk. The performer shakes the silk in the cascading confetti, and the silks is found to be completely colored in many bright attractive colors. It is again displayed clearly, stretched flat between the hands on both sides.
The effect can also be performed in reverse, though it would be a rare routine that requires all the pretty colors to vanish – this works just like our Chameleon Rainbow & Flag Streamers, with a picture silk. Complete and ready to use, with instructions.
