A gyroscopic exercise tool is a device used to
exercise the wrist as part of physical therapy or in order to build
hand and finger strength. It can also be used as a clever
demonstration of some aspects of rotational dynamics. The device
consists of a tennis ball-sized plastic or metal shell around a
free-spinning mass, which can be started with a short rip string or
by a snap of the thumb. Once the gyroscope inside is going fast
enough, a person holding the device can accelerate the spinning mass
to high revolution rates by moving the wrist in a circular motion.
