Marble Race Expansion

A GraviTrax expansion set builds on the fun a starter marble run set begins and makes it even more interesting to tinker with. A set helps a kid engineer take their track set-up to new heights or greater distance, or even incorporate an electronic element in the form of a marble-toting elevator, all while honing early STEM skills.
