each of the structural elements there is thus a substantial increase in the variety of track designs this flexibility also makes the marble track amusement device easier to assemble disassemble and replace or adjust portions of the track an alternate embodiment of the marble track amusement device 100 may consist of some elements being attached to a vertical support surface such as a conventional wall with other elements being attached to a horizontal support surface such as a table this allows the marble 170 to travel on both vertical and horizontal planes in a variation on this embodiment an u201c l u201d bracket or a re director can be affixed to either the vertical or horizontal support surface to allow the marble to travel in one plane divert to the other plane and then travel back to elements along the original plane the diversion from plane to plane can continue as many times as the user wishes the overall length and width of the track is only limited by the dimensions of the support surfaces and the strength of the means for attaching the track element to those surfaces in addition a track element may take the form of a trampoline a water wheel type mechanism or a catapult which can launch the marble 170 onto or into another structural element also since the various track elements can be mounted on planar surfaces with a 360 u00b0 freedom of orientation they can serve multiple functions for instance the bottom of a.
