ABSTRACT:
An apparatus for creating the illusion of a weighted body (10) rolling uphill on a diamond-shaped track (12) and demonstrating the geometrical relationship between the body and the track, includes a conically sectioned and tapered body (10) having plates (26, 28) disposed about its ends and a diamond-shaped track (12) having a pair of upwardly diverging spaced apart rails (50a, 50b) with apexes (20a, 20b) at their center portions and planar lower edges (38). The body (10), when disposed on the track (12), will roll unassisted towards the apex of the rails (50a, 50b) and continue to roll back and forth along the track (12) until coming to rest at the apexes (20a, 20b).
