Build six sleek, functional models of catapults, trebuchets, and launchers. Use these classic siege weapons to conduct simple experiments that demonstrate important physics and engineering topics like force, energy, motion, and trajectory. The included lightweight foam balls and soft darts are safe and effective projectiles to fling at your cardboard “castle” and other targets! The 36-page, full-color manual has illustrated step-by-step instructions for building the models and conducting the experiments.
