Assemble and off you go for a race on just one wheel! Thanks to astonishing gyroscopic effects, the racer maintains its balance. Simply put it together, mechanically charge the flywheel with energy, and the racer zooms across the floor. Completely battery-free and relying solely on rotational energy, the model can be recharged repeatedly, providing endless fun. The comprehensive manual not only explains assembly and functionality but also offers many challenge ideas and obstacle courses. Just give it a try!

This KOSMOS experiment kit showcases astonishing phenomena with a fantastic play experience and gives children aged eight and up their first insights into the world of physics.

Here, two physical phenomena come together to create action! Once assembled, the large flywheel of the mono-racer can be mechanically charged with energy, allowing the racer to effortlessly glide across the floor on one wheel. But why doesn’t it just tip over? Gyroscopic effects make it possible and keep the racer stable. These effects are explained for children in the easy-to-understand manual, which, in addition to assembly instructions and exciting facts, also includes creative challenge ideas. Whether in the obstacle course or on the hunt for new high scores – the mono-racer keeps the excitement alive!.
