Expand your marble run with the GraviTrax Tunnels – Color Swap set and turn every ride into a magical experience. As soon as the marble enters the tunnel, it instantly changes color. The tunnels can be used in two ways – with a marble preloaded or as an automatic color change during the ride. Ideal for creative builders and for extending your track’s possibilities. Works only with the GraviTrax Starter Set.
Discover a new dimension of play with the Ravensburger GraviTrax Tunnels – Color Swap expansion. Once the marble enters the tunnel, it “magically” changes color and continues on its way. This effect brings visual surprises to building and racing and adds even more fun for builders young and old.
You can use the tunnel in two ways: either insert a second marble before the start, or integrate it into the track so that the color change happens automatically. Thanks to the modular GraviTrax system, you can easily combine this set with other accessories to create unique marble runs full of action.
