Gravitrax Power Element Trigger Expansion Set

Ravensburger's interactive bullet track system.

As soon as a bullet rolls through the POWER-Trigger action element, a signal goes off. And you can set what reacts to this! Will he fire the Start so that a new bullet hits the track, reset the liver, or activate the Switch? You are in control!

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