Mouse Trap Meets Leonardo

Meet the STEM-friendly hydraulic gearbot. The completed, syringe-driven device will stand a foot tall and involve a completely unnecessary but fascinating series of gears and levers to hurl a projectile from the basket on the top arm. In dye-cut plywood, it takes an hour or two for an 8+ year-old. Includes all parts. All you add is patience and water.
