Mini Crossbow: Wooden Engineering Model Building Kit

Ready to storm an evil villain's castle? This mini ballista building kit is exactly what you need! Learn about engineering simple machines, physics, math, and history all with this STEM building kit. Building this wooden mini model kit helps demonstrate how a bent bow stores elastic energy and the mechanical advantage of a lever to multiply human force. Once built, you can launch mini projectiles and defeat those pesky beasts. The renowned Renaissance artist Leonardo da Vinci designed this crossbow. He was also a scientist, architect, engineer, and inventor. While we may have put this through an inshrinkerator, it would have been an intimidatingly giant crossbow or “ballista”. This design of a complex system of gears and pulleys demonstrates engineering and mechanics.
