Instructions
Wind the string attached to the Yo-Yo clockwise until the end comes up to the edge.
Place the loop at the end of the string around the index finger of your preferred hand.
Raise your arm and hand so that they are perpendicular to the floor. Bring your hand back down quickly as you release the Yo-Yo. Pull up on your hand so that the Yo-Yo is just skimming the floor.
Lower your hand so that the Yo-Yo is touching the floor. Extend your hand to force the Yo-Yo to run forward across the floor. Curl your index finger up to cause the Yo-Yo to reverse course and run backwards on the floor.
