发明名称 Dynamic toy apparatus
摘要 A track system includes an accelerator track section having a ferrous metal accelerator rod which attracts a magnetized spinning top and imparts a linear acceleration to the top. Additional coaster and turn track sections provide a selected glide path for the freely moving top. Alternate embodiments of the accelerator track sections include the incorporation of a guide channel, a "T" shaped accelerator strip, a planar accelerator strip, and a dual sided accelerator strip.
