Gravitrax Add On Expansion - Volcano.

The GraviTrax Volcano is an ideal addition to the interactive marble run system GraviTrax.

When a marble hits the back of the module the volcano 'explodes' and lets the thee balls fire off in all directions. Combined with a GraviTrax starter set this brings even more action into the exciting world of the marble run.

This pack is suitable for Starter Sets only.
