| SkyRail Suspension is the only marble run in the world that reproduces the spectacular technology of Suspension Bridges. The Central Tower is an architectural marvel, very light but rock solid, easy to lift and move around and most of all, extremely FUN to build. You can build the longest marble run in the world, spanning up to 32 feet. for spectaculary aerial tracks that even glow in the dark The ingenious cable system that supports the tracks in mid air is extremely easy to adjust; in this way you can speed up or slow down the marbles during their journey from the top of the tower to the bottom. Skyrail will accept marbles of various sizes ( 3 different sizes included ) to allow you to observe the different speeds with which they travel. An excellent learning tool to study the laws of dynamics. Ages 6+ |
