Pathfinders STEM Kit – Medieval Onager Catapult | Build Your Own Working Siege Engine | Wooden Model Kit for Teens and Adults | Educational STEM Project for Home or Classroom

• BUILD TIME: ABOUT 60 MINUTES – A rewarding, hands-on mechanical build that results in a clean, functional medieval siege engine model once assembled
• AGE 14+ – Designed for teen and adult builders who appreciate historical engineering, mechanical systems, and hands-on construction projects
• FULLY FUNCTIONAL ONAGER – Torsion-powered throwing arm uses twisted rope tension to launch projectiles, allowing experimentation with force, distance, and trajectory
• INSPIRED BY MEDIEVAL WARFARE – Faithfully modeled after historical Roman and medieval onagers, showcasing early torsion-based siege technology and mechanical ingenuity
• MECHANICS & PHYSICS EXPLORATION – Assemble, adjust, and test variables such as rope tension and launch angle to explore real-world principles of energy transfer and motio
