This video demonstrates how to make a rock-throwing catapult using a variety of primitive tools and techniques. The first step is to recycle timber from the demolished thatched workshop. Next, the timber is cut into 2-meter lengths and cane is split so it's easier to lash with. Three poles are then lashed together at one end and spread out to form a tripod. A cross is then set up next to the tripod and logs are cut into rough joints to form the throwing arm. The throwing arm is attached to the cross and the cane basket is tied to the arm. The catapult is then tested and found to be functional.
