Trebuchet Model

With a simple counterweight, beam arm, and sling, the trebuchet launches heavier projectiles much further than is possible with other siege engines by transforming gravitational potential energy into kinetic energy. A ping pong ball is included, but feel free to experiment with marshmallows, jelly beans, bouncy balls and other safe objects. Two release pin angles allow exploration of how the release angle changes the trajectory. The main material is high quality precision-cut Birch vernier pure bond plywood. All necessary parts are included and shown in picture, holes are pre-drilled. The included guide provides clear assembly instructions with pictures. It also contains pedagogy for exploring concepts of energy transfer using the scientific method.
