Tenyo Four Nightmare DX is great visual rope magic! A long piece of rope and a short piece of rope are displayed to the audience. When stretched out together, they somehow become equal in length.The magician ties the two ropes together. Then the knot is miraculously slid off of the rope and the magician is left with one long piece of rope which is used to tie a knot in its center. The magician grasps and squeezes the knot. The knot melts completely away! Now the magician ties one final knot in the middle of the rope. This time the knot is very large. With no false moves the loop is slid cleanly off the rope as well, leaving the magician with a piece of rope in one hand and an endless loop of rope in the other hand. Finally the loop of rope and the long rope are tied together, but suddenly, the knot dissolves, and magician is left with one single long rope! The gimmick is special because the props are very-well made. Even up close, the audience cannot see the secret. The professional nature of this rope is evident in its clean beauty and thickness, which allows it to work well for close up, parlor, and stage.
