Leonardo da Vinci didn't invent the catapult but, as with anything that crazy Medieval MF touched, he did figure out how to make it way better. And I think if high-rise office buildings, contemporary desktops, and floors with dozens of co-workers existed in 1485, da Vinci would have been the Father and Grand Master of cubicle warfare just like he was of painting, architecture, mechanical systems, paleontology, ichnology, and Dan Brown novels. With this Leonard da Vinci Catapult Kit, you can get a hands-on peek into the Italian stallion's greatness. It includes all 2 dozen+ pre-cut parts needed for assembly, and even the glue because da Vinci wouldn't have been shiesty about selling key components separately like that.
The Leonardo da Vinci Catapult Kit is suitable for beginner model makers, but more appropriate for strategic engineers looking to launch organized spitball, Cheese Ball, and maybe melon ball attacks against the product managers.
