Details:

Investigate physics using technology from medieval times! 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 32-page, full-color manual has illustrated step-by-step instructions for building the models and conducting the experiments.

Warning! Not suitable for children under 3 years. Small parts and small balls — Choking hazard. Long string and long rubber bands — Strangulation hazard. Keep the packaging and instructions as they contain important information. Warning! Do not discharge an object other than the projectile provided with this toy.
