The GraviTrax Element Jumper takes balls to new levels and creates new paths. Differences in height on the train can be overcome spectacularly. If a ball rolls into the jumper, it is transported spectacularly upwards and continues to roll on a higher level. At the same time, a passage tunnel is created for the next balls. Combined with any GraviTrax starter set, the Element Jumper brings completely new energy to the ball track. 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 ball tracks and researching the rolling behavior of the balls, the understanding of science is sharpened and gravity can be experienced up close. 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 through countless expansions with classic building elements or stones that enable special action and tricks. This means everyone can tinker, try things out and push themselves further.
