Explore hydraulics, pneumatics, and robotics with your very own giant hydraulic hand.
Using over 200 plastic pieces and piston tubes that you fill with water, build an awesome 16 inch mechanical hand that uses hydraulic power to simulate the movements of the human hand - no motors or electricity required! Once assembled, your adjustable cyborg hand slips onto your own hand like a glove, with mechanical fingers that can grip objects with enough force to lift them. Challenge yourself to pick up a variety of items like bottles, pencils, small items - anything within reach! Complete with a 40-page full-color manual that includes awesome experiments and mind-boggling scientific information about hydraulic systems in robots - cool!
