Two silk hanks tied end-to-end are displayed. They are pulled through the hand and the hanks change color! This trick is mechanical version of the double color changing silk hanks. The mechanism for the color change is self-contained. It looks good and is very easy to do. Note that these hanks are made from actual silk, and not from nylon or polyester, which do not do the this great trick justice. This is a wonderful trick for the beginning magician and a great trick for kids to perform. 018RUMCCSILK4SILK_12
