This 81-piece wooden marble run set includes blocks, tracks, marbles, and all necessary components to build a customizable racing track. The set features interactive elements like a jump, bell-bucket, spiral funnel, marble wheel, and 18 dominoes to create varied marble paths. The open-ended design allows for unlimited configurations, with compatibility to connect with other Hape marble run sets for expanded play. The set introduces basic physics concepts such as gravity, momentum, and potential energy through hands-on experimentation. Constructing the track supports skill development in hand-eye coordination, logical thinking, and problem-solving. Made with child-safe paint and durable wood, the set is designed for children ages 3 and up.
