Gravitrax Power Element Start Finish Expansion Set

Ravensburger's interactive ball track system.

In this set you get the individual POWER elements from the Starter Set Launch. You can install the Trigger anywhere on the track to activate the Start. This means a new bullet enters the trajectory! This set also works together with all other POWER elements, for even more action on the track.

With the GraviTrax® ball track system you can discover gravity in a playful way and it can be expanded with various extensions for limitless building and playing fun! Add even more speed with the expansion sets.
