The Oribel Vertiplay STEM Marble Run blurs the line between play and learning.

Unlike traditional marble runs, fitting the modular tracks and ramps directly to the wall mats allows you to change and micro-adjust configurations quickly, without the inconvenience of toppling towers or running out of support pieces. It enables focused creative play, encouraging children to explore and experiment with gravity, forces and motion principles so they can design, test, adjust and problem solve with ease.
