Children aged 8 and up have even more surprising building possibilities with the GraviTrax Color Swap.

The Color Swap brings a new surprise moment to the GraviTrax world. As if by magic, the ball changes colour when it passes through the stone. This can be prepared in two ways. Either by loading the stone with a ball at the beginning, or by installing it into the track accordingly. Thanks to the illusion of colour change, the colour swap provides a visual highlight. How often can the colour of the balls be changed during a pass?

At GraviTrax, building fun has a free way. The GraviTrax marble run system can be infinitely enlarged by extensions, which guarantees unlimited building and fun. By freely designing the marble runs and exploring the rolling and flight behaviour of the balls, the understanding of science is sharpened and gravity is made skin-tangible. The STEM sign on our products signifies a game category with which science is playfully experienced. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German STEM (Mathematics, Computer Science, Natural Science, Technology).
