Show a clear plastic tube, 10 inches long. Three silks, red, yellow and blue, are placed one at a time into the tube. Blow the silks out of the tube, and they fly out–knotted together!

Sometimes I like to open my kid shows with this effect, and other times I will put it in the middle of the show as a solo piece, after I have done some audience participation. tricks.
