Abstract
The present invention is an improvement on the spinning top that includes a plurality of radial indentations, notches, or holes along the outer circumference. It also includes a sloped, geometrically shaped stem, topped with a rounded gear used to spin the top. A plurality of square-holed inserts which lock in place when inserted over the sloped, square stem, are also provided for demonstrating STEM concepts. The indentations, when spinning, highlight the effect of AC electric light by creating a strobing effect that appears at first to move with the rotation of the top, then appears to stand still, and then reverses rotation. The interchangeable parts or spokes make it possible for the invention to have variable geometry that allows the invention's mass, balance, and weight distribution to be modified. The invention's indentations, interchangeable spokes, and graphical locking inserts can be used individually or in unison to demonstrate and teach various STEM concepts. The invention can also be used for entertainment and to produce interesting visual and sound effects.
