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 Communication Station with a rotating Radar Dish, Power Station, Rover Charger, Space Rover with Motor, non-powered Space Rover both with wheels and light-up headlights. Or connect the pieces your way to make your own, out-of-this-world, custom builds! Then launch into hours of screen-free, pretend-play fun with two included astronauts and two robot figures.
