This video demonstrates how to make a rock sling similar to one that would have been used in the Bible story about David and Goliath. The sling is made out of one piece of rope. An intricate knot is made in the rope to serve as the pouch that holds the rock. The video shows slow, step-by-step instructions for how to weave and tie the knot in the center of the rope so that it looks like a small basket about 2" wide. Make a finger tether at one end of the rope. This video can be used to make your own sling shot weapon.
