Experience endless fun and learning with the National Geographic 95-Piece Marble Run Set! Featuring a motorized lift that transports marbles up 16 inches, this perpetual motion machine keeps your marbles rolling again and again. The kit includes 61 construction pieces, 20 marbles, and a motorized spiral lift, giving you everything needed to build endless marble maze configurations.





Fantastic STEM marble run with real wow-factor, but setup takes patience
The motorized lift and tall spiral track are genuinely impressive, keeping the marbles looping nonstop and making this a big hit for kids who love motion and cause-and-effect. I really like that it’s compatible with other National Geographic marble sets and comes with a clear learning guide that sneaks in physics concepts without feeling like homework. However, the initial assembly is a bit fiddly, and younger kids will need an adult to help stabilize the taller builds and troubleshoot occasional jams. I’d still recommend it for patient builders and STEM-loving kids around 8+ (with some adult help), especially families who enjoy tinkering together.
Fantastic STEM marble run with a cool motorized lift, but a bit finicky to assemble
The motorized lift on this National Geographic marble run is genuinely impressive—it keeps the marbles cycling smoothly and turns the whole setup into a mesmerizing, continuous-motion display. I also love that it’s compatible with other Nat Geo sets, so you can build bigger, more creative tracks and use the guide to sneak in some real physics learning. That said, the 95 pieces can be a little tricky to snap together firmly, and if kids bump it, certain sections may come loose and need adult help to re-stabilize. I’d still recommend it for kids around 8+ (and parents who like to build too), especially for families looking for a fun hands-on STEM activity with some patience for setup and occasional tinkering.
Motorized Lift Makes It Way More Engaging Than Our Basic Marble Run
We used to have a simple gravity-only marble run with no moving parts, and the kids would lose interest pretty fast once the marbles reached the bottom. The motorized lift on this National Geographic set keeps the marbles cycling nonstop, so they stay engaged longer and experiment more with track designs. The included physics learning guide is also a clear step up from our old set, but the real game-changer in daily use is that automatic lift — it actually gets used regularly instead of sitting in the closet.
