The Quercetti Marble Runs accompany the child through growth, encouraging the discovery of the basic principles of physics and dynamics, but more than anything they are just complete and utter fun. First one can enjoy independently building up the paths in thousands of different ways and with extreme ease, thanks to the fact that the easy-to-use and intuitive parts simply slot into place together. After that, one can test the freshly-conceived runs with the included marbles, which are amazing fun to watch as they plummet down, along straight sections, curves, ramp-jumps, and tunnels. In other words, our marble tracks ensure endless hours of enthralling playing, either alone or in good company.
