Abstract:
1. A set of segments for building a complex track for guiding a marble comprising: a plurality of longitudinal segments having at least first and second walls joined to one another along a longitudinal edge of each, a magnetic strip on the outer surface of said first wall of each of said segments to permit mounting said segments on a ferromagnetic surface, the angle between said first and second walls being sufficiently less than 90 degrees to hold whatever marble is rolled along said linear against said first wall, members of said set of said segments having variable lengths, said magnetic strip providing a magnetic attraction low enough to permit manual fine adjustment while continuing to maintain contact with whatever surface is used as the backing for the segment, whereby the user can arrange said segments in a complex pattern, each segment being in communication with one or two other segments to provide a multi-segment complex path for a rolling marble, wherein said magnetic strip is a same length and height as said first wall of each of said segments, and wherein said magnetic strip is flush with said first wall of each of said segments.
