This is a catapult ala torsion style I built inspired from the video a contributor named schoondogs posted. His catapult looked simple enough so I thought I'd make a step-by-step with some improvements that's the American way right? The design is not pretty but it is very functional and that's really all a 5 year old cares about anyway. It took about three hours to build not counting the trips to Home Depot and does not include any difficult cuts all straight cuts or elaborate tools. Did you use this instructable in your classroom?

Show less The strength of a catapult could refer either to the sturdiness of the catapult frame and its ability to withstand use, or it could refer to the force with which the catapult launches projectiles. However, knowing how to build the frame of your catapult can actually help you understand how to build a sturdier machine and launch a projectile farther with even greater force.
