NATIONAL GEOGRAPHIC Magnetic Marble Run - 75-Piece STEM Building Set for Kids & Adults with Magnetic Track & Trick Pieces & Marbles for Building A Marble Maze, STEM Project (Amazon Exclusive)

My family loved putting this together and making their it their own. The magnets are good but sometimes the pieces fall off when the marble is doing its run. I’d say splurge and get the one with the most pieces. We felt like the run was too short once we used all the pieces.

We must have had this on our fridge for months. It was a fun way to be creative and problem solve as a family while cooking dinner. We are a family that tends to congregate in the kitchen haha.

Kids love it, me too

I purchased this magnetic marble run set for my 8-year-old and it's been a big hit! The 75 pieces offer a good variety of tracks, trick pieces, and marbles, making it easy to create a wide range of marble maze designs. The magnetic tiles stick well to a magnetic board or the fridge, and the clear plastic track pieces let you see the marbles race through—which adds a fun visual element.What we loved:STEM Learning in Action: My kid quickly got into problem-solving mode, figuring out how to get the marbles from top to bottom without falling off or getting stuck. Great for encouraging creativity and engineering thinking.Strong Magnets: The magnets are surprisingly strong. Once you lock the pieces in place, they stay put, which is especially important for tall builds.Colorful and Engaging: The bright colors and the variety of track shapes kept things interesting, and it was fun for both kids and adults to join in.A few tips:Use on a Magnetic Surface: This set doesn't include a magnetic board, so make sure you have a surface like a whiteboard, fridge, or magnetic easel ready.Plan Your Build: Start with a basic design and gradually add complexity. Gravity is key here—make sure each track has a proper downward angle or the marble will stall.Combine Sets: If your kid really enjoys this, consider buying an expansion set. 75 pieces are enough for fun builds, but a larger set offers more creative options and stability for bigger designs.Why 4 stars and not 5:Limited Stability: While the magnets are strong, the plastic tracks can pop out if you bump the structure or if the design is too ambitious without proper support.No Base Included: A magnetic board or base plate would’ve been a helpful addition for easier setup and play.Overall, this is a solid and educational toy that sparks curiosity and creativity. A great gift for STEM-minded kids, especially if you already have a magnetic play surface at home.

This toy set is great! My nephews loved playing with it and setting it up on their fridge. Lots of tiny parts though, so beware of losing any marbles or tracks if you have smaller kids or pets!

Sent as a gift. Recipient was very happy.

Fantastic idea, but needs to go back to drawing board for some strengthening tips so you get your $$ worth.Very very fun activity. I have it on the side of the fridge and every child that comes in has to inspect and play with it.I've created a number of configurations with all 6 of my grand children now. Each one having a blast. The poor reviews pretty much nailed all the issues I also had with the set.. but it's certainly worth more than a 1 rating. I wouldn't go above a 3 due to the expense of it vs the quality.Value? well it's not really for little fingers and frankly the pieces break, twist, or come apart very easy. They don't really snap in as nicely as you would hope so that adds to the difficulty of getting a working structure. Plus the magnet wasn't really strong enough to keep the pieces in place after 1 or 2 marble runs.Our set was missing pieces, one piece missing was vital to the battery operated Shute. We worked around that missing piece. but that was a bummer.I would have to say we got a ton of fun but 70 dollars is a lot to pay for something that's pretty much ruined after a few months, (and not because of rough play either). It's really fragile so it should be considered for older kids.

awesome product
