Ravensburger GraviTrax Extension set - colour change

Children have even more surprising building possibilities with the GraviTrax Color Swap. The Color Swap introduces an element of surprise into the GraviTrax world. As if by magic, the ball changes color when it passes the stone. This can be set up in two ways: either by loading a ball onto the stone at the beginning or by integrating it into the track accordingly. The illusion of the color change creates a visual highlight. How often can the color of the balls be changed during a run? With GraviTrax, building fun knows no bounds. The GraviTrax marble run system can be infinitely expanded with extensions. By freely designing the marble tracks and exploring the rolling and flying behavior of the balls, understanding of science is sharpened, and gravity is made tangible. The STEM label on GraviTrax products indicates a category of play where science is experienced in a fun way. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German MINT (Mathematics, Computer Science, Natural Sciences, Technology).
