The GraviTrax Add on Hammer is an expansion item that can be combined with the GraviTrax Starter and Pro Set.

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.

GraviTrax is a STEM interactive marble run that allows players to design and build tracks, whilst experimenting with gravity, magnetism and kinetics to explore endless possibilities and infinite creativity.

Create action-packed track systems with 18 different construction elements. Discover how the laws of physics affect the track your ball takes. The construction plans and tasks provided make it easy for you to begin and soon you will construct your own track designs.

Use the free app on Android and IOS for the GraviTrax ball track system with its free editor to build your very own fantastic tracks, and then roll the balls as you watch from different angles. Try endless new combinations and come up with new ideas to build your tracks. Experience the tracks interactively and follow the balls from a variety of camera angles - including in Virtual Reality if you have the right glasses and a compatible phone.
