Gyroscope - The Original Fidget Spinner!

The gyroscope was invented around the early 19th century and was originally used as a teaching aid, and later used by Leon Focault in an experiment to demonstrate the Earth's rotation.  Gyroscopes are currently used for navigation, aerial videography, accelerometers, and many other uses. Our gyroscope is completely hand machined using an aluminum frame, brass rotor and screws and a stainless steel axle. The adjustment screws have been tipped with stainless steel ball bearings.  Note: the adjustment screw should NOT be tightened down, as the bearings are very small and can be damaged by too much lateral pressure. The gyroscope comes with a brass base and small insert pin for use with the spin base.  A kevlar pull string and brass pull handle are also included. Rotor Diameter: 1.670". Weight: ~140 grams Height: 2.5" You can watch a not-so-great video here.
