Instructions
Release the yo-yo from your right hand and allow the yo-yo to loop around your left pointer finger. You'll know you did this correctly when the yo-yo string is looped around your left pointer finger. With the left hand slightly in front of your right hand, you will create a "V" with the yo-yo at the point.
Place your right pointer finger in between the two strings that rest half an inch down from your left hand.
Swing the yo-yo a little bit to gain momentum, and then swing the yo-yo toward you going under and over your right hand.
Push your left hand forward, then bring it under the yo-yo so that your hand ends just under your right hand. To end on one rotation you can go immediately to step five. To continue the barrel roll you'd immediately continue to bring your left pointer finger under and over your right hand. Continue this motion of looping around your right hand until you're ready to dismount. The yo-yo string should be wrapping around your right pointer finger if you're performing this correctly.
Unravel the yo-yo by swinging the yo-yo away from your body and around your left finger. Snap the yo-yo back into your right hand.
