Marble Race Starter Set

starting at $54.99
Build, configure, and perfect a marble run ┃Expansion sets and accessories amp up the fun
The GraviTrax starter set is the perfect rolling, spinning, racing, and jumping-off point for kid engineers. The marble run building set has over 100 pieces and nine construction plans to put into action, or kids can create their own signature twisting and turning race track while honing early STEM skills with concepts like gravity, trajectory, and force.


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.
