Designed for ages 14 and up, this advanced STEM kit offers a hands-on mechanical build that showcases real engineering principles through functional design. The Onager uses twisted-rope torsion to store and release energy, demonstrating physics concepts such as tension, force, and projectile motion. Precision laser-cut wooden components ensure accurate assembly and a durable finished model capable of launching projectiles. Ideal for history enthusiasts, STEM learners, and hobby builders seeking a challenging and rewarding project, the Roman Onager combines education, craftsmanship, and authentic mechanical action in one striking build\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBUILD TIME: ABOUT 60 MINUTES - A rewarding, hands-on mechanical build that results in a clean, functional medieval siege engine model once assembled\u003c\/li\u003e\n\u003cli\u003eAGE 14+ - Designed for teen and adult builders who appreciate historical engineering, mechanical systems, and hands-on construction projects\u003c\/li\u003e\n\u003cli\u003eFULLY FUNCTIONAL ONAGER - Torsion-powered throwing arm uses twisted rope tension to launch projectiles, allowing experimentation with force, distance, and trajectory\u003c\/li\u003e\n\u003cli\u003eINSPIRED BY MEDIEVAL WARFARE - Faithfully modeled after historical Roman and medieval onagers, showcasing early torsion-based siege technology and mechanical ingenuity\u003c\/li\u003e\n\u003cli\u003eMECHANICS \u0026amp; PHYSICS EXPLORATION - Assemble, adjust, and test variables such as rope tension and launch angle to explore real-world principles of energy transfer and motio\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eProduct Details:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PATHFINDERS","offers":[{"title":"Default Title","offer_id":44377493110849,"sku":"MCAB07QTZ45RR","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/6321\/7729\/files\/81epbFuIkTL.jpg?v=1786466857","url":"https:\/\/toycartusa.com\/products\/pathfinders-stem-kit-medieval-onager-catapult-build-your-own-working-siege-engine-wooden-model-kit-for-teens-and-adults-educational-stem","provider":"ToyCartUSA","version":"1.0","type":"link"}
