Die Rolle ist eine einfache Maschine aus Hartholz, die Kindern hilft, die Eigenschaften der physikalischen Wissenschaft zu erkunden. Sie bewegt Gewichte mit einem System aus Rädern und Seilen.
The hardwood wheels spin so smoothly that my daughter could lift her heavy backpack all by herself. It’s a simple setup that really teaches how the cord and wheels share the load.
My five-year-old spent a good hour figuring out how to lift a small toy with the pulley system, and the smooth hardwood held up perfectly. I just wish the included cord was a bit longer for more ambitious projects—still, it’s a solid introduction to basic physics.
