National Geographic Marble Run with Motorized Elevator - 95-Piece Marble Maze Kit with Motorized Spiral Lift, 20 Marbles, Perpetual Motion Machine, STEM Gifts for Boys and Girls, Kids Physics Toys

The National Geographic Marble Run is hands-down one of the best STEM toys I’ve bought. The pieces are sturdy, colorful, and fit together securely, which means the tracks stay stable even during high-speed marble races. The set comes with plenty of pieces to build multiple designs, and the instructions are clear while still leaving room for kids (and adults!) to get creative. My nephews love experimenting with different track layouts, and I love that they’re learning about gravity, momentum, and problem-solving while having a blast. The marbles run smoothly without getting stuck, and the variety of track pieces (funnels, ramps, and twists) keeps things exciting. It’s the perfect blend of educational and entertaining — a great gift for curious minds that will keep them engaged for hours. Highly recommended for both family fun and hands-on learning!

Our family had so much fun with the National Geographic Marble Run with Motorized Elevator - 150‑Piece Marble Maze Kit! The motorized elevator keeps the marbles moving without stopping, and the endless build possibilities make it endlessly entertaining for kids (and adults too). It’s great for learning problem-solving and basic physics while having a blast together. Highly recommend for hands-on play and creativity!

Kids loved it for Christmas. It has a lot of pieces and you can build it different ways.

It’s a great set for kids to build but I wish they included a book for design ideas. Some pieces we don’t even know how to use or how to connect them and there are no instructions.

I bought it for my grandson. It was a huge hit with my grandson and Son In Law. They both had a blast playing with it. Big hit.

Over time I have purchased four different sets of this National Geographic brand. I teach STEAM. The kids LOVE these to death! The very first time I handed over the elevator — they snapped the spiral. Bought a pricey plastic repair kit to fix it, but when I called the vendor’s number at thinkbluemarble.com to determine the correct type of plastic rod to use — the representative — unsolicited — offered to send a replacement. I still want the name of the type of plastic to use, because my overeager students are sure to snap it again. Otherwise, the sets have held up well despite repeated abuse.

Very, very cool set! The motorized piece works well, and the plastic pieces are made well, also. This is a nice, large set and worth the money.
