With the GraviTrax trampoline element, the ball bounces over the built GraviTrax track. In this way, obstacles and height differences in the track can be impressively overcome. If a ball falls onto the trampoline, it bounces directly to a higher level and thus defies gravity. Combined with any GraviTrax starter set, the trampoline element brings a whole new level of momentum and energy to the marble run.

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.
