Quercetti linksmieji kalneliai "Roller Coaster Mini Rail" 6430

With ROLLER COASTER you can build fantastic marble runs with suspended tracks up to 8 meters long. The colourful suspended rails will immediately become the best attraction in your room! ROLLER COASTER has been specifically designed so that marbles of different sizes and materials can be used: it prompts kids to make interesting observations, while experimenting and discovering the world of physics (speed, gravity, centrifugal force, friction) and to intuitively understand its fundamental principles. Playing with ROLLER COASTER is a safe and unique way to spend hours in a highly educational environment.
