The CENTRAL TOWER is an architectural marvel, very light but rock solid, easy to lift & move around & most of all, extremely FUN to build. Then assemble the rails & connect the cables & you will have built an exciting aerial pathway that will become the main attraction of your playroom. With the RAILS of SKYRAIL SUSPENSION you can build the longest marble run in the world, spanning up to 45 feet, for spectacularly aerial tracks, that even glow in the dark. T he track can be assembled in many different ways: some are illustrated in the enclosed manual, but you can invent many other ones freely expressing your creativity. With Skyrail marbles don't travel only downward at constant speed like in old fashion marble runs, but can accelerate impressively down steep slopes then climb uphill until almost reaching a stop, roll quietly along flat plateaus, & then again down chilling plunges at full speed. 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 is designed in such ways that most types of marbles can run along its tracks: 3 types are included in this box. Each marble type will run at different speed & will allow you to observe, experiment & discover the world of physics forces & to understand intuitively its fundamental principles. This is actually an exceptional education value.
