Requires the GraviTrax Starter Set (sold separately).
Propel the marble through your run by adding the Hammer. When triggered, the hammer swings down and hits the marble, giving it momentum to send it on its way. With the hammer you accelerate your ball again so that it can roll even longer! Combine the hammer with the GraviTrax starter set and bring even more action into your tracks. This accessory also includes 6 additional tracks.
