Description
Grab, move, lift and crush! You control the Hydraulic Robot Arm like modern day construction equipment. Powered by tap water alone, the Hydraulic Robot Arm only needs a few pumps to energize the cylinders and power up. Like a crane or bulldozer, when you move the levers and prime the pump, a series of hydraulic cylinders expand and contract to control the movement of the arm. The Mad Science Hydraulic Robot Arm introduces kids to science and discovery while sparking their imagination.
