An elementary treatment of the theory of spinning tops and gyroscopic motion
In the "sleep" period, and only in it, provided it is ever reached, less friction means longer "sleep" time whence the common error that less friction implies longer global spinning time. There have been many developments within the technology of the top. Bearing tops, with a tip made of a small hard ceramic, tungsten carbide or even ruby ball sometimes wrongly believed to spin with respect to the body of the top , have been one of the biggest changes.
In addition, plastic and metal have largely supplanted the use of wood in tops. A top may also be used to demonstrate visual properties, such as by James David Forbes and James Clerk Maxwell in Maxwell's disc see color triangle.
By rapidly spinning the top, Forbes created the illusion of a single color that was a mixture of the primaries: . Forbes, which I witnessed in … [established] that blue and yellow do not make green, but a pinkish tint, when neither prevails in the combination…[and the] result of mixing yellow and blue was, I believe, not previously known. Maxwell took this a step further by using a circular scale around the rim with which to measure the ratios of the primaries, choosing vermilion , emerald , and ultramarine. Asymmetric tops of virtually any shape can also be created and designed to balance.
Gould lists the six main types of tops as the twirler, supported top, peg-top, whip-top, buzzer , and yo-yo. The bully and the named top in the title are challenged by Shepherd's ongoing protagonist Ralph and a so-called "gypsy top" of similar design to Mariah named Wolf.

This educational program from the somewhat hyperactive science popularizer Bill Nye covers the basics of spinning things like tops.
At the end has a video clip song "Spin Around" from House of Spin.
