Hydraulic Arm Kit - 176 Pieces

Children can discover the power of hydraulic energy by building their own robotic arm! Operating on a push system where pressurised liquids transfer a great deal of force, the jumbo claw grips and moves with its six-lever control panel. They'll tinker with the base, arm, clamp and tubes to make this little gadget come to life right in front of their eyes.*No batteries required, as this device completely operates under hydraulic power. Once the arm is assembled, simply add water and push the levers to move the robotic arm around.Features: ages 10 and up includes 176 pieces
