Wizzer

From Wikipedia, the free encyclopedia

Wizzer is the brand name of a line of gyrostats intended as childrens' toys. Wizzers may be described as cowled tops, or as covered gyroscopes. They are currently manufactured by Duncan (company), better known for its yo-yos.

Wizzers are not sold as scientific instruments, but they are an excellent teaching tool for learning about the conservation of angular momentum and gyroscope stability.
