The Prosthetic Hand Challenge, now through June 30, at the Lawrence Hall of Science. Children can design, build and test a working prosthetic hand. The exhibit, a partnership with CITRIS and the Banatao Institute, draws on projects developed in the CITRIS Invention Lab, including Sophie’s Super Hand and Million Hands.
