The Outback Collection of marbles by King Marbles consists 20 x 16mm marbles and 1 x 50mm marble of varying colours and styles. Playing instructions included. Marble colours and sizes may vary to image shown.
Build a 32 metre, marble roller coaster with the SpaceRail, level 5 construction set. Use the included guide to connect rails through a network of twists, turns and loops and then reconnect back to the battery-powered elevator. When built, a steel marble is dropped allowing gravity and the SpaceRail roller coaster set to send the marble on it's journey. When the journey ends, the steel marble is collected at the base of the elevator and lifted back to the top where it's released again for it's next journey down. Adjust the pitch and you control the descent/speed. It's fascinating to watch and loads of fun to build.
