Spacerail marble runs and construction sets for kids and adults

Let the marbles race through spirals and loop-de-loops—Spacerail turns gravity into a gripping spectacle. This gravity-powered marble run and Spacerail construction set brings creative building, smart mechanics, and the freedom to design your own track with bridges, spirals, and steep drops. Every model blends physics, engineering, and fun into a single STEM experience for kids and adults.

A signature feature of Spacerail is the battery-powered electric lift, which smoothly returns the steel marbles back to the start. Flexible plastic rails, sturdy supports, and precision parts ensure smooth operation, stability, and long run times. The sets offer various track lengths, loop-de-loops, transitions, and crossings for a roller-coaster effect and maximum speed.

Choose your kit by difficulty—from Level 1 for beginners to more challenging levels for advanced builders. Spacerail marble runs develop fine motor skills, logical thinking, patience, and spatial imagination; assembly with the detailed manual is clear and fun. The modular design allows modifications and extensions to your tracks, giving you endless experimentation and an eye-catching model for display.
