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)

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!

Amazing . Kids was playing for hours. However you must have a big fridge or create a steel wall

Good fun, but be careful as they slide around when left on the fridge. Unfortunately this lead to a couple of parts getting caught on the door and they broke. Could have done with a sturdier material maybe, or more care to be taken.

Good quality. The kids love it, only thing, there is nothing to actually catch the balls, so we have marbles bouncing on our tiled floor, a small inconvenience . Great fun

Educational and doesn't take up space on the floor. Comes with a travel bag so you can easily take it to someone else's house. Pieces are sturdy and the magnets stick well. Instructions were easy to follow and encourage trial and error to get the pieces exactly in the right place or to make your own design.

My son is 9 years old and we bought him this for Christmas. This has to be the best present I bought for anyone. We have all had so much fun with it, the creativity to work out new runs learning to do small adjustments to make it work, it's been brilliant. We struggled getting the hang of the Catapult but that's just us, only downside is not being able to buy add ons. I wish I'd bought the bigger set but well will just have to get that next. Highly recommend this. Also we have used an old wipeboard rather than the fridge which has been perfect especially as we can move it around

It is a toy, and I'm an engineer, probably I was expecting too much of it based on other reviews. The magnets are the weakness here, they are simply not strong enough. I had to supplement them with fridge magnets to enable reliable operation. The static elements that receive no shock loading are fine. However, when a marble drops onto an element, even a very short distance onto any track, or rotating, or other element, the element will move a small amount each time. without extra support. Fine, if this is to be used as a toy, but with this shortcoming, it is not possible to obtain repeatability over more than a few circuits due to the elements moving around. The fact that this comes with a lift, means that the elements need to remain where placed in order to provide cyclic operation. The marbles are also a weakness, none are spherical, just watch them as they roll! they are very poorly made and would be best, substituted for better ones. Overall, a great toy for a child, but not a gift for an engineer with expectations of repeatability.

Bought as a gift for two boys (8y,11y) and they played with it for hours … week later - still spending 1-2h a day changing the layouts/ improving the strategy. Highly recommended! We had kids age range 5y-14y visiting over Christmas and they all loved 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

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!

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
