GraviTrax, an all - new STEM track system from Ravensburger, lets you use your imagination to build amazing tracks and set the Gravity Spheres rolling! The Transfer expansion set is a real show - stopper, taking your marbles across a breathtaking gap. Combine it with your GraviTrax Starter - Set to send your marbles on long - distance adventures. How far can they go?


Using the GraviTrax Transfer is super easy. First, connect it with your GraviTrax Starter - Set as instructed. Then, place the Gravity Spheres on the track and watch them roll across the gap. When using, make sure the connections are secure to avoid the marbles falling off. Also, keep the track clean to ensure smooth rolling. If there's dust or debris, simply use a soft cloth to wipe it down. Store the set in a dry place to prevent any damage.
