Oh the gravity of it all! The sleekly designed GraviTrax system, has young engineers and imagineers building innovative race tracks as they experiment with and learn about how the laws of physics (gravity, magnetism and force) work as the track configurations change.

With 100 pieces, the term “starter set” may be a misnomer. The sheer variety of materials and construction components lets builders discover how to control the speed of the gravity spheres, aka the six shiny metal marbles. Our testers took some time going through the construction element overview and then leapt right into the challenge. Suggested construction plans are color coded in six levels of difficulty from easy to hard; the image only design guide does not progress in the same way. Some testers methodically worked through the guide, others blazed their own trails.
