This is a cool old school trick!

 

1.Throw a Sleeper.

 

2.With your free hand, grab the string halfway down the yo-yo.

 

3.Now with your yo-yo hand, grab the string about 3 inches away from the yo-yo.

 

4.As you bring your free hand down...

 

5....spread your two fingers apart, so the string opens sort of like a triangle.

 

6.Now you have a cradle, rock the baby! Now just let go and pull up, but don't get the yo-yo stuck in the string!
