Ballista Catapult Kit - Build Your Own Working Catapult With Ping Pong Balls

About This Product

Future engineers and physics enthusiasts, this ballista catapult kit is absolutely awesome for hands-on learning! Everything you need comes in the box - wood components, leather pouch, ping pong balls, dowels, pre-measured string, and clear instructions. No tools required for assembly, which is part of the fun and learning process. Once built, your ballista can launch ping pong balls over 30 feet using four different launch angles, letting you experiment with parabolic trajectories and projectile motion. The torsion spring mechanism (made from twisted mason twine) demonstrates real physics concepts like force, energy transformation, mechanical advantage, and torsion springs in action. It's part of the Eisco Garage Physics line, designed specifically for STEM education through hands-on building and experimentation. The repeatable launches make it perfect for classroom demonstrations or at-home learning, safely exploring physics concepts through play. The wooden components are precision-cut from birch veneer plywood, so the quality is much better than typical toy kits. Whether you're a teacher looking for engaging science demonstrations, a parent wanting educational fun, or just someone who loves building working mechanical devices, this ballista delivers both learning and entertainment. It's one of those rare educational toys that's actually cool enough that kids (and adults!) will want to play with it repeatedly while accidentally learning real physics principles. Building and experimenting has never been this much fun!
