With the GraviTrax Transfer element, balls are phenomenally transported through the track. The ball is carried along the track, allowing it to overcome height differences in the course. When a ball rolls onto the Transfer, it impressively propels the ball further. Combined with any GraviTrax starter set, the Transfer element brings new momentum to the marble run.

GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and up. With GraviTrax, children, teenagers, and adults can not only build simple marble runs but also create unique marble run worlds. By freely designing the marble runs and exploring the rolling behavior of the balls, understanding of science is sharpened, and gravity is experienced up close. The GraviTrax universe includes three exciting lines: CORE, PRO, and POWER. All GraviTrax lines and products can be freely combined. With countless expansions using classic building elements or stones that enable special actions and tricks, the GraviTrax universe can be infinitely expanded. This allows everyone to tinker, experiment, and build beyond their limits.
