How does this work?? Really well!
A visual mystery! Two blue silks and a red silk are hanging from a pole. At your command, the red silk jumps between the blue silks! Then each silk is freely removed from the pole- no threads, wires or gimmicks!
The silks will be blue and red. Since all the silks are removable, you can replace them with 18" silks of your choice to create a specific theme, such as using blue and yellow silks for a Cub Scouts Blue and Gold theme.
