Blue Marble National Geographic Glow-in-the-Dark Marble Run Expansion Pack – 5 Glass Marbles, 20 Construction Pieces

Expand, Glow, and Explore with Blue Marble

Turn a simple marble run into a glow-in-the-dark playground with the Blue Marble National Geographic Glow-in-the-Dark Marble Run Expansion Pack. Designed to enhance existing National Geographic Glow in the Dark Marble Runs (non-magnetic), this expansion adds a set of pieces that unlock brighter paths, more intricate routes, and richer hands-on learning experiences. The glow of the marbles brings a tactile, visual element that resonates during after-dark play, inviting kids to observe, predict, and tinker as light meets motion.

What’s in the expansion

• 9 tube pieces
• 9 action pieces
• 2 base pieces
• 5 glow-in-the-dark glass marbles

With these pieces, you can extend your marble maze beyond the original footprint, creating longer runs, bolder slides, and new challenge points that keep curiosity alive. The included trick pieces introduce twists and alternate pathways, adding variety without sacrificing stability.

Glow-in-the-dark experience

The five new glow-in-the-dark marbles light up as they zig-zag through the maze, offering a striking visual cue that responds to light exposure. The result is a luminous, kinetic play moment that can be enjoyed in dim rooms or after sunset, enhancing focus and anticipation as every run unfolds.

STEM-focused play and learning

• Learning Guide inside explains motion physics and basic aerodynamics in kid-friendly terms.
• Marble run construction experiments encourage experimentation, hypothesis testing, and iterative design.

Whether used for solo exploration or cooperative building, the kit supports hands-on inquiry in a tangible way. It presents possibilities rather than guarantees, inviting players to experiment with angles, heights, and speeds to see how small changes influence the outcome.
