How to Put Ball Bearings in a Yo-Yo

The yo-yo is an ancient toy whose appeal has lasted thousands of years. Historical references and artifacts indicate yo-yos were in use as early as 440 B.C. In the 1970's, new yo-yo models enabled the axle to be modified. Today, sleeved and ball bearing axle models help yo-yo enthusiasts perform advanced tricks. Various types of ball bearings are available, from simple ones that cost a few dollars to ceramic versions that may cost $30 or more. Ball bearings create less friction and make tricks easier to perform.
