Build, configure, and perfect a marble run┃Expansion sets and accessories amp up the fun
Add on a GraviTrax accessory to send a marble run building set in a new direction. A cannon, trampoline, or loop piece each helps kid builders hone early STEM skills and get hands-on learning experience with concepts like gravity, trajectory, and force while they race to the finish line—and have lots of fun doing it.
With over one hundred pieces and nine potential construction plans (plus whatever little engineers dream up on their own), the GraviTrax marble run set provides endless building, reconfiguring, and racing good times.
It draws on STEM skills by giving kids hands-on experience with concepts like gravity, magnetism, and kinetics, and there’s some creative thinking needed, too—not that they’ll notice that. Kid builders will be too busy experimenting with height and trajectory and perfecting their twisting and turning race course. Expansion sets let a race track reach a grander scale, and accessories like a trampoline and cannon amplify the fun.
