At last, a catapult kit that uses the same power source as the ancient and medieval catapults – torsion! By twisting the strings holding the launch arm, students can launch small projectiles with this fun siege machine. Plus, it’s great for helping students understand how to apply torque, potential and kinetic energy, projectile motion, and more.
Requires a small screwdriver, white glue, and scissors, sold separately. Available as a single kit or a pack of 10 kits.
