"Skyrail Suspension" Rails are suspended in mid-air through a series of ties and anchors, just like a real suspension bridge. Watch the marbles race down and around. Rails and some marbles glow in the dark. Physics fun for the beginning engineer! Perfect for demonstrating gravity, speed, inertia, weight and other principles of mechanics and physics.
