Description
🏆 2025 Best in STEM — STEM.org
Build your own ballista inspired by the ancient Greek and Roman siege weapon — re-imagined with the hand-held mechanics of a crossbow. Our award winning design is easy to assemble and incredibly satisfying to use, this kit lets you explore how rubber band tension stores potential energy and releases it as kinetic energy — sending small projectiles flying across the room.
With a removable top that exposes the internal mechanism, you can actually see the crossbow-style action at work as you load and launch. Plot the trajectory of your projectiles and experiment with how adding rubber bands or changing their size affects launch distance and accuracy.
What makes this kit special:
- 🏆 Recognized as Best in STEM by STEM.org
- Ancient Greek and Roman ballista design re-interpreted with handheld crossbow mechanics
- Visible internal launching mechanism
- No glue required — precision laser-cut wood pieces press fit together
- Customize with paint or markers to make it your own
- Launches pom-pom projectiles safely indoors
- Build multiple kits and let the battles begin
Perfect for classrooms, science fairs, homeschool physics, birthday parties, and maker enthusiasts. An engaging STEM activity that makes ancient engineering feel as exciting today as it was 2,000 years ago. Recommended for ages 8+.
Made of laser cut birch plywood
