OVJ STEM Cardboard Marble Run Inspiration Kit

This cardboard marble run kit is a hands-on makerspace project that invites students to explore mechanics, motion, and motorised movement through simple materials.

Designed entirely from brown corrugated cardboard, it features a spiral ramp and a rotating lift system powered by a small motor and battery. As marbles roll down by gravity and are lifted back up in a continuous loop, students can observe real-world physics concepts in action — from kinetic energy to circular motion.

More than just a toy, this kit encourages experimentation. Builders can explore how the motor connects to the lift mechanism, tweak the incline of the ramps, or even challenge themselves to redesign it to move the most marbles with the least energy. The flat base provides a stable platform for modification, making it ideal for iterative design and group projects.

Perfect for classroom makerspaces or after-school programmes, this project supports creativity, problem-solving, and STEM learning through cardboard engineering. It’s not just about following instructions — it’s an open invitation to innovate.
