The effort to get kids interested in science just got a big helping hand—a cyborg hand, to be precise. The award-winning Mega Cyborg Hand ($39.95), created by educational toymaker Thames & Kosmos, helps kids build a robotic arm that mimics their hand gestures, while they learn about hydraulics, pneumatics, engineering and robotics. You won’t find any wires, motors or electronics; instead, the toy consists of plastic pieces and piston tubes filled with water. Once assembled and slipped on like a glove, the device uses hydraulics to transmit forces from the user’s fingers to the extended digits of the robotic hand. The Mega Cyborg Hand can be adjusted to fit hands of all sizes, easily switching from left-handed to right-handed to “claw.” —Jared Lindzon
