Winner of the 2021 Toy Associations STEAM Toy of the Year and TIME’s Best inventions of 2021, this is the kit that enables a child to assemble an air- and water-powered robotic hand. Using the principals of STEAM (Science, Technology, Engineering, Art, Math) education, it provides young engineers with over 200 pieces that snap and screw together to form an oversized, four-fingered claw. Once assembled, it fits over a child’s hand like a glove and is operated using their own fingers. An included manual provides step-by-step instructions as well as experiments that study range of motion, hydraulics, and pneumatic systems. Ages 7 and up. 16” H. (1 1/2 lbs.)
