Construction lay 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 including a Deluxe Base Station with Towers, Rotating Diner Sign, Planetarium with Color Changing Dome, Voice Synthesizer that includes 10 space sounds, Communication Station with rotating Radar Dish, and one fully-powered Space Rover and a free rolling Rover, both with Light up headlights. Or connect the pieces your way to make your own, out-of-this- world, light-up, space station! Then launch into hours of screen-free, pretend-play fun with six included astronauts and two robot figures.
