Ready to storm the evil villain's castle? Look no further because a miniaturized giant crossbow is exactly what you need! Introducing Leonardo Da Vinci's crossbow, a fantastic kit perfect for your siege needs. Learn about engineering simple machines with this STEM building kit. Once built, you can launch mini projectiles and defeat those pesky beasts. The renowned Renaissance artist Leonardo da Vinci was also a scientist, architect, engineer, and inventor. He created many weapons. While we may have put this through an inshrinkerator, it would have been an intimidatingly giant crossbow or “ballista”. Da Vinci's design featured a sophisticated mechanism with a crank and a complex system of gears and pulleys, showcasing his deep understanding of engineering and mechanics. This DIY mini model kit is hands-on learning at its best. Model building kits decrease stress, increase focus, organization, spatial and fine motor skills. A mini wooden craft kit to explore engineering, simple machines, and historic replicas. A great summer craft for kids, teens, and adults that will bring all ages together for a project. Details: Pre-cut wooden models for DIY assembly For ages 8+ Estimated build time 30 minutes Built dimensions 6” x 3 ½” x 2” (mini!) Includes educational manual
