Even more building fun can be experienced with the helix criss-cross, topsy-turvy!

Up to six routes can cross with the Helix. If a ball leaves the stone, it rolls on to a lower level without changing its direction. This means that up to six balls can pass the stone at the same time. Combined with a starter set, more complex tracks can be built without the balls blocking on their way to the finish. How many balls can pass through the helix in one go?

With GraviTrax, building fun has free rein. The GraviTrax ball track system can be expanded infinitely through extensions, which guarantees unlimited building and playing fun. By freely designing the ball tracks and exploring the rolling and flight behavior of the balls, the understanding of science is sharpened and gravity can be experienced up close. The STEM mark on our products signals a game category where science is experienced through play. STEM (Science, Technology, Engineering, Mathematics) corresponds to the German MINT (mathematics, computer science, natural sciences, technology).
