Trestle-propulsion-principle : these three concepts work together to create an innovative marble-run experience like no other. Each track has as opening that gradually widens from one end to the other. When placed on this opening, the ball perpetually falls forward, transforming the force of gravity into a unique form of propulsion. Using this principle and the easy-to-stack risers, young engineers are able to build endless variations of kinetic fascination!
