This YO-YO is made out of cedar wood.
Yo-yo (also spelled yoyo) is a toy consisting of an axle connected to two disks, and a string looped around the axle.
Yo-yo is played by holding the free end of the string known as the handle (by inserting one finger—usually the middle or index finger—into a slip knot) allowing gravity (or the force of a throw and gravity) to spin the yo-yo and unwind the string . The player then allows the yo-yo to wind itself back to the player's hand, exploiting its spin.
