In the center about five-foot length of rope tied the two loose node, one above the other, as shown in the figure. Without untying this dual node, divide it into two separate.
At first glance, the solution seems impossible, Ask the audience to hold the ends of the rope. Then dilute the nodes in different directions.
How to do it? Bottom, the first node must be thrown over the rope (in the direction of the second node) and pass it through this, the top node. The result is on the rope will be two separate sites. Method of breeding sites is clearly seen in the figure.
