To do the around the world trick you are going to hold your yo-yo just like in the forward pass. Bring it down to your leg. However, instead of just shooting it out and stopping your wrist by turning it over, you will want to continue a swinging motion. Notice how your hand will kind of allow it to swing. When you want to snap your yo-yo back you will need to stop your hand and let the yo-yo shoot to it. So to review this, you throw, let it swing, let it shoot back to your hand. If you would like to practice the swinging motion try just let the yo-yo go and just try swinging it around. What you want to do with this is get it to stay all the way at the end of the string without kind it falling back. If it does then you're not swinging hard enough. What will happen then is the yo-yo is just going to shoot back to your. Practice this a few times. Once you feel like you got that down, try and combine it with your forward pass move.
