Chameleon Knots by Jay Scott Berry

You display 2 2439 diamond silks, one red and one white. They are tied together and a knot is tied in the center of each silk. Your hand is passed over the silks and the knots visually change places. That39s right, the red knot is now in the center of the white silk and the white knot in the center of the red! Another pass of the hand returns them to their original positions. Then, each knot is untied and the silks are shown!
