Add some extra creativity to your Gravitrax collection with the tiptube expansion! Combine the GraviTrax starter set with the tiptube accessory. Round up your marbles with the tiptube and set them free again, shooting them out simultaneously. Stop, collect, and release! How long can you pause your marbles with the tiptube?
 
With the GraviTrax interactive track system and marble run, you can design and build your own race tracks and experiment with gravity, magnetism, and kinetics to propel your ball to the finish. The track can be infinitely extended with various add-ons for endless building and racing enjoyment!
