The GraviTrax Color Swap element changes the color of the balls as they pass through. If a ball rolls into the Color Swap, the color of the ball changes as if by magic when it leaves the element. The illusion can be created in two ways. Firstly, the element can be loaded with a ball at the start or the Color Swap can be built into the track. Combined with any GraviTrax starter set, the Color Swap adds a whole new dimension to the track.
GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and over: With GraviTrax, children, teenagers and adults don't just build simple marble runs. They create unique marble run worlds. By freely designing the marble runs and exploring the rolling behavior of the balls, the understanding of science is sharpened and gravity can be experienced at first hand. The GraviTrax universe includes three exciting lines - CORE, PRO and POWER. All GraviTrax lines and products can be freely combined with each other. The GraviTrax universe can be expanded infinitely with countless extensions with classic building elements or bricks that enable special action and tricks. So everyone can tinker, try things out and build beyond themselves.
