THE GIZMOS & GADGETS KIT, 2ND EDITION IS THE ULTIMATE INVENTION TOOLBOX. It transforms passive screen-time into a passion for hands-on inventing, problem-solving and creativity. It’s the first littleBits kit for young inventors that allows them to build inventions AND control them with a tilt, shake or tap of their smart device. Invent a remote-controlled car and let your phone do the steering. Or build a caterpillar that crawls with the tap of a tablet! Comes with 13 electronic building blocks, instructions for 16 inventions, and all the accessories and tools you need to unleash the inventor within.
