Gyroscopic Exercise Tool

A gyroscopic exercise tool is a device used to exercise the wrist as part of physical therapy or in order to build palm, forearm and finger strength. It can also be used as a unique 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 is started with a short rip string. 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.

Famous quotes containing the words tool and/or exercise:

    The veto is a President’s Constitutional right, given to him by the drafters of the Constitution because they wanted it as a check against irresponsible Congressional action. The veto forces Congress to take another look at legislation that has been passed. I think this is a responsible tool for a president of the United States, and I have sought to use it responsibly.
    Gerald R. Ford (b. 1913)

    The exercise of letters is sometimes linked to the ambition to contruct an absolute book, a book of books that includes the others like a Platonic archetype, an object whose virtues are not diminished by the passage of time.
    Jorge Luis Borges (1899–1986)
