The Original Marble Run by Discovery Toys has been engaging children since 1982. This set allows kids to construct custom marble raceways featuring 8 distinct marble actions. Children can launch marbles through ramps and chutes, creating dynamic movement patterns. The system includes interactive elements like the Snake, Paddle Wheel, and Jump ramps that enable experimentation with multiple track configurations. This educational toy supports STEM learning by developing visual tracking skills, fine motor control, and hand-eye coordination as children manipulate marbles along the tracks. It demonstrates principles of gravity, cause-and-effect relationships, and spatial concepts including in, out, on, under, and through. The product complies with all US safety standards and is constructed from non-toxic, BPA-free materials. Discovery Toys has produced developmental play products for over 40 years, focusing on toys that build foundational learning skills through hands-on exploration.
