Pathfinders Gearbot Hydraulic Catapult Kit

This DIY catapult uses hydraulic power to launch the projectile of your choice, be it popcorn or toasted oats. With the push of a water-filled piston, you set a whole range of fun movement into action. An intriguing mix of levers, hydraulics, rack and pinion gears, meshed gears, a spinning propellor, and extending scissory thing make for an immersive STEM experience. Test your launching skills for accuracy and distance with the clay projectiles, and experiment with launch angles, lever length and different projectiles. Safe enough that you can fire popcorn into a willing partner's mouth, and powerful enough that you can knock down small block walls. Comes with great instructions and educational material.
