This is the circuit kit that lets young engineers and gamers assemble a working pinball game. Employing the principals of STEM (Science, Technology, Engineering, Math) education, the kit’s 60 parts can be easily assembled to perform 20 experiments using simple and safe circuit building techniques. It helps children learn the fundamentals of electricity as they connect the circuits and route electrical currents to illuminate LEDs, send electric signals, and adjust the volume. The kit has eight pinball themes including cartoon, space invasion, dance party, and rollercoaster. Includes activity guide with full color experiment diagrams. Requires three AA batteries. Ages 8 and up. 12" L x 10" W x 2 3/4" D. (2 1/4 lbs.)
