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 mechanical hand that uses hydraulic power to simulate the movements of the human hand--no motors or electricity required! Once assembled, your cyborg hand slips onto your own hand like a glove, with mechanical fingers that you operate with your own fingers and that can grip objects with enough force to lift them. Challenge yourself to pick up and hold a variety of items like bottles, pencils, small items--anything with reach! The hand can be configured in three ways--left hand, right hand, and claw-like, with the thumb in the center--and can be adjusted to fit virtually all hand sizes.Details:203 piecesIncludes 5 experiments52-page manualAdjustable joints for different gripsFor ages 7 and up
