This is an excellent comedy prop that has been a favorite with Kid's magicians and clowns since the beginning of time.
You show a bright colored 24" silk and tie a knot on it. Since you tied the knot at the wrong spot you try to slide it and lo behold! It slides up and down and finally comes out. Unlike most other versions of this trick the center of the silk is NOT cut and hence can be used with routines that need a silk. This silk can also be used in a "Do as I Do" routine wherein you try to do the exact same steps as the spectator, but you end up with a comically different result than his.
We carry this trick in Red, Blue & Yellow. Please specify the color while ordering.
