Build your own BIG hydraulic hand, slip your hand into it like a glove, and operate the mechanical fingers with your own fingers. Assemble the cyborg hand using over 200 plastic pieces, fill the piston tubes with water, and adjust it to fit your own hand.
Thames and Kosmos makes great kits and the manuals are so full of great science information. They are truly a step above other science kits!
Thames & Kosmos was founded in 2001 by a science museum director and her son, who saw the great need and demand for better science education materials — resources for parents and their children that are more engaging, more effective, more relevant, and more fun.
