Brings a new level of excitement to building a marble maze!
The National Geographic 150-Piece Magnetic Marble Run STEM Building Set brings a new level of excitement to building a marble maze! With its innovative spiral lift and magnetic connectors, kids and adults alike can build, create, and explore engineering and physics on any magnetic surface.

This STEM marble run set provides everything you need: Spiral lift with power pack; 7 spirals and end piece for variable height; 44 magnetic connectors; 26 track pieces; 32 trick pieces - 3 funnels, 2 arounds, 2 corners, 3 flex, 4 poles, 3 simple spinners, 2 spinner pros, 1 bell, 2 switches, 2 catapults, 8 U-turns; 25 marbles; storage bag; detailed instructions, and fact-filled Learning Guide.

Explore physics and engineering with the different types of track and trick pieces, creating astonishing chain reactions and intricate paths for your marbles. First, select a combination of track, trick, and connector pieces and arrange them creatively on any vertical magnetic surface. Place a marble at the beginning of the course and watch it make its way down your track. As you experiment and create, simply move the pieces around to make adjustments, add new pathways, or build new obstacles. Each track and trick has its own unique properties, but how to set them up is completely up to you—the possibilities are endless!

The National Geographic Magnetic Marble Run isn't your ordinary marble maze. From the kitchen to the office, it's an engineering kit with a Rube Goldberg machine-style of play that's super fun and satisfying. It’s also a fun, collaborative way to connect with family, friends and co-workers! The magnetic connectors work in tandem with the included track and trick pieces for endless marble run combinations and maze-like experiments on any magnetic surface. The connectors are sturdy yet easy to move around as you build and fine-tune your track. Its unique design also means less clutter on the floor, with a handy, durable storage bag to keep all your pieces and marbles safe and secure.

And like all National Geographic STEM kits, the 150-Piece Magnetic Marble Run includes a detailed, illustrated Learning Guide to teach the science behind all the fun. Learn how to think like an engineer with an understanding of Newton's laws of motion, gravity, energy and more!
