Additional Set for the Constructor - GraviTrax Power Addition

GraviTrax - experience the power of gravity! 

GraviTrax is an interactive marble tracking system that you can design and build yourself, experimenting with gravity and exploring the laws of physics.  The GraviTrax Power Switch & Trigger extension is a unique set of elements that, when combined with the basic version, will allow you to expand and diversify your track, offering endless trajectory design possibilities. 

Attention! This is not a standalone game, but an extension. 

To play with it, you will need the GraviTrax Starter Set (4005556260997) or GraviTrax PRO (4005556268320).
