Three silk handkerchiefs, each of a different color, are freely displayed to the audience. A clear, plastic tube is displayed and then the three silks are placed into the tube, one at a time. The end of the tube is then placed to the mouth and the silks are blown skyward. Incredibly the three silks fly out of the other side magically tied together. The Crystal Silk Tube is easy to learn and perform. 10″ long Crystal Tube. Three silks included. Colors may vary.
