A mini-powerhouse, this precision engineered trebuchet uses guillotine action and a plunging beam to maximize potential energy and a floating arm to convert that energy into projectile motion. The result is an ancient machine powered by modern science that can send a golf ball flying through the air for nearly the length of a full football field. Detailed instructions and high quality hardwood pieces that have been pre-cut and pre-drilled are all provided, so you can construct a finished model in just one day. Test your machine’s strength and efficiency with the included equations and tips as you watch classical mechanics in action. Note: This is a functional model intended for educational demonstrations of physics. It contains a fast moving arm and projectile that can cause injury if you make contact when firing. Size: 34″H x 18″L x 12″W.
