National Geographic Magnetic Marble Run STEM Building Set for Kids | Magnetic Track and Trick Pieces, Marble Maze, Engineering Toy, Creative Construction, STEM Project for Kids and Adults

This magnetic marble run is brilliant. Instead of fragile plastic tubes that fall over, these track pieces attach magnetically to vertical surfaces like the fridge or a whiteboard or fridge. The trick pieces add a ton of problem-solving fun, keeping both kids and adults engaged for hours, building unique mazes. Even after being brushed off the frig so many times, nothing has broken. The assembly is easy to complex, depending on the age.

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!

Good fun, a little tricky to figure out how some of the parts work. Used the side of clothes washer.

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.

Fun for the whole family! Brought back some nostalgia for my husband. Put this on the fridge door and the kids love playing with it. I have a small cup with the marble held by a chip clip so we don't lose it. The magnets are pretty strong. It stays stable in the high traffic area. Easy to use. My kids are 6 and 8 and my husband is 40, we all enjoy it. It's cool and teaches us about little changes and movement. Really fun.

My 10-year-old son LOVES this marble run! While the magnets can move slightly, it has never created an issue for him, and he has made many complicated and impressive runs from it!

A little complicated at first

Fun toy for the grandkids.

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!

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

磁石が少し弱い感じがしました。 商品は良かったと思います。
