Construction play meets electrical engineering in this simple, snap together building system – powered by real circuits! Line up the circuitry graphics on the oversized pieces and snap them together to build a fully powered, large-scale, space-themed world. Follow the easy instructions to build a Rocket with light-up Nose Cone and Nozzles, Space Rover with light-up headlights, and Landing Pad with color changing light effects—or connect the pieces your way to make out-of-this-world custom, light-up, builds. Then launch into hours of screen-free, pretend-play fun with the included astronaut and robot figures!
