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)

Strong magnets and quality marbles and parts. Hours of fun

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!

I can't explain to you how cool this is... but realize that if this is a gift for your kids you are probably going be the one doing the work and putting it together... but once you do have it assembled in the way that you want, (ther is a learning curve), you will be able to swap out different sections, change up the route. You can create multiple routes that the marble can go. So yes. Its a great gift, but it is also a responsibility for whatever adult the kid belongs to. Assembly is simple enough after you get going. And if you're going to put magnets on your fridge, it might as well be cool ones that move marbles up and down and around.

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.

good quality toy. it could use stronger magnets so the pieces stay put, but over all it is good

My six year old nephew is very into rube goldburg videos, so this was a great intro into making things work. It’s a great way for him to learn how to construct and it’s a great toy for someone his age.

The plastic is cheap, inflexible, and brittle. The corkscrew broke immediately just during assembly and it is too small and under too much stress to be glued. Well done Nat Geo. Wonderful holiday gift of poor quality junk.

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!

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 !

Super divertente e stimolante! Regalo perfetto per bambini che vogliono costruire e inventare percorsi sempre diversi.

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!
