Designed for kids ages 8 and up, this expansion pack includes one Loop tile, six track pieces, and works with any GraviTrax system. It’s a hands-on way to explore gravity, physics, and problem-solving.\u003c\/p\u003e\u003ch2\u003eWhat the Loop Does\u003c\/h2\u003e\u003cp\u003eThe Loop tile sends the marble upside down along a circular path. To succeed, the marble must have enough speed entering the loop – otherwise it will fall. This forces builders to experiment with track pitch and height to build up velocity. It’s a simple but effective lesson in kinetic energy and centripetal force, wrapped in a fun challenge.\u003c\/p\u003e\u003ch2\u003eCompatibility with Other GraviTrax Sets\u003c\/h2\u003e\u003cp\u003eThe Loop accessory is designed to snap into any GraviTrax system. Whether you have a starter set or other expansion packs, all components use the same connection design. This means you can add the Loop to existing tracks or plan a new layout that includes it. GraviTrax is fully modular, so you can keep expanding over time.\u003c\/p\u003e\u003ch2\u003eWhat’s Included in This Pack\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eParts\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 Loop tile, 6 tracks (1 long, 2 medium, 3 short), instruction sheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAge Recommendation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 years and up\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAll GraviTrax sets and expansions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eHow Does the GraviTrax Loop Affect the Marble’s Movement?\u003c\/h2\u003e\u003cp\u003eThe loop introduces a vertical inversion. As the marble travels upward, gravity slows it. If it’s not moving fast enough at the top, it will drop. You can increase speed by raising the starting point or by using gravity drops from other track pieces. This experiment teaches cause and effect: small changes in track design produce big differences in outcome.\u003c\/p\u003e\u003ch2\u003eSTEM Learning Through Building\u003c\/h2\u003e\u003cp\u003eGraviTrax is more than a toy – it’s a tool for learning. The system uses gravity, magnetism, and kinetics without batteries or screens. Building a working marble run develops spatial reasoning, planning, and perseverance. The Loop accessory adds a new variable that requires careful adjustment, deepening the educational value. Boys and girls ages 8 and up can enjoy it, and it’s also popular with adults who like to engineer complex tracks.\u003c\/p\u003e\u003cp\u003eGraviTrax has sold over 15.5 million units worldwide and is the top marble run system in the U.S., according to the NPD Group. This popularity reflects its lasting appeal among kids and parents. The Loop makes a thoughtful gift for curious builders, especially when paired with a starter set.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCan I use the Loop with my existing GraviTrax starter set?\u003c\/strong\u003e Yes, all GraviTrax accessories and expansions are compatible with every set.
