The Loop, a GraviTrax expansion set, adds a spin to your marble run. The marble enters the loop, but how much speed and momentum does it need to complete the loop? The set includes 1 Loop tile and 6 tracks (1 long, 2 medium and 3 short) to add to your current setup.
GraviTrax is a creative, modular, expandable track system that challenges children to use their imagination to design and build their own marble runs! Electronics-free, GraviTrax construction sets use STEM-friendly concepts while building critical thinking and problem-solving skills. Completely open-ended, every GraviTrax set has a boredom-busting variety of play options for hours of fascinating fun.
This is an Expansion set, and requires a GraviTrax Starter Set in order to work.
