Blue Marble Glow-in-the-Dark Marble Run Kit — 75-Piece STEM Set for Ages 8–12 with 15 Glow

Build glowing, gravity-powered marble courses with the Blue Marble National Geographic Glow-in-the-Dark Marble Run — a durable, STEM-focused kit with 75 pieces and 15 luminous glass marbles designed for ages 8–12.

This hands-on construction set invites children to design intricate marble tracks that glow at night while teaching basic physics concepts like momentum, friction, and energy transfer. The kit combines snug-fitting components and sturdy bases so tracks stay connected during play, plus a storage bag to keep parts organized between sessions. Developed exclusively for Amazon and designed by the award-winning Blue Marble team, it blends open-ended creativity with guided learning experiments from National Geographic.

How many pieces are included and what do they do?

The set contains 75 pieces that work together to create track systems of many shapes and lengths. Pieces lock together for stability and the included bases support taller or wider builds.

• 5 stable bases to anchor multi-level sections
• 15 action pieces such as funnels and drops for exciting motion
• 45 clear, smooth-run track sections for consistent rolling
• 15 glow-in-the-dark glass marbles in six colors for nighttime play

What makes this marble run good for STEM learning?

A short learning guide explains the mechanics behind the designs and offers simple experiments to explore concepts like speed, slope, and aerodynamics. Kids can test hypotheses, change variables, and observe outcomes, reinforcing scientific thinking through play.

• Step-by-step experiments that illustrate motion and forces
• Opportunities to test cause-and-effect by altering track layouts
• Encourages measurement, planning, and iterative design

Are the parts durable and easy to store?

The components are engineered to snap together tightly so the marble courses resist accidental collapse during active play. After use, everything fits into the supplied large storage bag to keep marbles and track pieces together and protected.

• Precision-fit track connectors reduce wobble and separation
• Robust bases support extended builds and tumbles
• Reusable storage bag simplifies cleanup and transport

What makes the glow-in-the-dark marbles special?

The 15 glass marbles charge from ambient light and emit a soft glow, creating an eye-catching contrast when tracks are dimmed or used after sunset. Multiple colors help players track different runs or run-time variations.

• Glow marbles in six colors for visual variety and tracking
• Glass construction provides smooth, consistent rolling
• Visible performance in low light for evening challenges

Who this is for: This kit is ideal for curious kids aged 8–12 who enjoy building, experimenting, and fine-detail play. It suits parents and educators looking for a tangible STEM activity that blends creativity with clear learning outcomes. Collectors of construction toys and families seeking a reusable, award-winning product will appreciate the durable parts and guided experiments. Because Blue Marble developed this item in partnership with National Geographic and exclusively for Amazon, it also appeals to buyers who value vetted educational brands and straightforward storage solutions.
