First
invented in 1852 by the French physicist Leon Foucault in his
investigation of the rotation of the earth, gyroscopes have been a
classic educational toy for generations.
The all metal gyroscope has
ultra-high quality bearings and a plastic base that holds the winding
string and metal mounting stand.
The metal stand can also be used to
mount the gyro to hold it when not spinning. ideal for educational
purposes, it demonstrates the properties on inertia, angular motion, and
precession.
