Black to Rainbow Scarf

The magician takes a long black scarf gracefully from his shoulders and shows it to the audience. Gently he shakes it or waves it in the air, and the scarf visibly changes from black to rainbow-colored.  The effect may also be performed in reverse, that is from rainbow-colored to black. Or, after turning the black silk to rainbow, you can make it go black again.

Approximately 43" long x 5.5" wide.
