National Geographic Magnetic Marble Run - 150-Piece STEM Building Set for Kids & Adults with Magnetic Track & Trick Pieces & Marbles for Building A Marble Maze, STEM Project (Amazon Exclusive)

I purchased this for my nephews, and it has been a massive hit! From the moment they opened the box, they were completely captivated by the endless possibilities for building and creating. The magnets are strong and sturdy, making it easy for little hands to assemble and disassemble the pieces without frustration. I love how this set encourages creativity and problem-solving while also teaching basic STEM concepts in such a fun and engaging way. My nephews have built everything from simple shapes to complex structures, and their excitement never fades! As a bonus, the included guidebook provides great inspiration for new designs, but the kids love to freestyle their own creations too. It’s a perfect blend of fun and education, and I feel great knowing it’s helping them develop important skills like spatial awareness and teamwork. The quality is fantastic—durable, safe, and well-made. It’s also compact enough to store easily, and the storage bag is a thoughtful addition for keeping everything organized. I would highly recommend this to any parent, teacher, or caregiver looking for a creative, hands-on activity for kids. Whether for playtime, homeschooling, or just some screen-free entertainment, this set is worth every penny!

Very nice set - durable pieces. Have held up very well thought out tons of play.

Got this for our son. It’s a lot of fun to play with. Only draw back so far which is likely a surface issue and not the products issue is when we use it on our black stainless fridge which is magnetic the pieces tend to move with force of the marbles hitting them. So it’s just turned into how do we slow down or lower the velocity the marble is traveling at to make it so we don’t need to adjust ever couple of marbles. Other than that it had 4 adults playing with it on Christmas. It is very engaging

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.

Excellent gift for highly intelligent children when you’re looking for something unique to excite them. It seems like a simple concept, but it really energizes the imagination. It’s not cumbersome if it’s on your fridge and it holds up to repeated dropping. Personally, I love it for having my little one near me while I’m in the kitchen doing dishes or cooking.

My 10yo son LOVES science and magnets. He's had the marble run towers before. But this one is so different, all the magnets with diff pieces that do diff acts. He's obsessed with coming up with new routes to make, and problem solving to make it work. Easy too assemble, when you're not using it, it just stays on the fridge with a nice lil bag.

This is super fun and the possibilities are endless! My 12 yr old son and my 8 yr old daughter both love it!

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.

Lo compre para mi hijo de 10 años y le encanto. Funciona perfecto, nunca lo vi tan enganchado y entretenido con un juguete. La calidad me parecio buena, los imanes agarran bien, quizas hay que hacer algun ajuste despues de haber tirado la bola porque puede que haga pequeños movimientos sobre los imanes y no corre bien la proxima vez, pero es muy divertido

Cadeau de noël pour mon fils. Il adore !

A super tool to help Littles learn about the push and pull forces of magnets! An education and fun toy that also helps foster imagination and creativity!

This kept my 12 and 9 year old quite occupied with a good dose of frustration while they figured it out. There’s a plan in the box to follow too and it didn’t scratch my fridge freezer either. Great purchase!

Buena calidad Desarrolla su ingenio, muy padre a mi hijo le encanto
