Throw a fast spinner. Put your hand in the "I swear" position, and move your elbow around in front of the string.
Keeping your elbow high, lower your hand to the string and give it an upward jerk.
The yo-yo will climb the string over your arm and drop in front of you where you can pull it back to your hand.
Rock the Baby
Practice making the cradle with a dead yo-yo before trying it with a sleeping yo-yo. With the yo-yo hanging at the end of the string, hold your yo-yo hand up like a policeman saying "stop."
Reach between your thumb and first finger with all four fingers of the other hand and pull the string back down until it forms a triangle.
Swing the yo-yo through the triangle a couple of times. Drop the string and the yo-yo will return to your hand if it is spinning fast enough.
