THA Catapult Engineering: 6-in-1 Maker Kit

Investigate physics using technology from medieval times. Build six updated models of catapults, trebuchets and other launchers that fling foam balls and soft darts, and learn mechanical physics concepts such as force, energy, motion and projectiles. Durable plastic pieces can be reconfigured to build models from the illustrated 32-page full-color manual or create your own designs. The kit includes experiments, folded cardboard blocks to build a pretend castle wall for knock-down play, and activities that teach projectile mechanics.
