A crystal clear plastic tube is shown to the audience. Three different colored silk hanks are tucked into the tube. The audience can clearly see the hanks through the clear plastic. The magician blows the hanks out of the tube and the hanks have “tied” themselves end-to-end! This is easy to do magic that will make you a star! Comes complete with three silk hanks, tube, and easy-to-follow instructions. Please note that silk hank colors sometimes vary.  007RUMCRYSTALTUBE
