With the GraviTrax Action Set Energy, marble runs get the necessary momentum and energy to make marbles roll dynamically up and down!

With the diverse GraviTrax elements of the Energy Action Set, marbles can travel through different levels of the track, gaining momentum time and time again. Use the Light element from the POWER line to build upwards and give your marbles a boost with the Vertical Cannon. There are no limits to creativity and fun – perfect for builders who want a tricky marble run experience full of variations!

GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and up: 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 marbles, their understanding of science is sharpened, and gravity becomes a tangible experience. The GraviTrax universe includes three exciting lines – CORE, PRO, and POWER. All GraviTrax lines and products can be freely combined. With countless expansions using classic building elements or bricks that enable special actions and tricks, the GraviTrax universe can be expanded infinitely. This allows everyone to tinker, experiment, and push themselves to their limits.
