With the Magnetic Stick, balls can be reached and picked up even in difficult spots on the marble run. The magnetic tip of the Magnetic Stick accessory attracts the silver and colorful GraviTrax balls as if by magic. It can be easily assembled before the first use. Additionally, the set includes a silver ball for even more marble run fun.

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, an 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 featuring classic building elements or stones that allow for special actions and tricks, the GraviTrax universe can be infinitely expanded. This way, everyone can tinker, experiment, and build beyond their limits.
