These are called "Blind Catches." http://youtu.be/mZyMtRvjh8Y

Related to magic: When we make a ball appear, we don't get that sense of 'there is nothing, now something.' Only the spectators get that feeling. We KNOW there is already a ball in the hand waiting to appear (or flower, or wine bottle, or whatever.)

During this trick, it felt truly magical because all I had to do was put my hand in the appropriate area, and a ball appeared. TRULY it was a magical sensation for me. (I'm a selfish magician/juggler.)

Props to you man, i just began juggling about two days ago and ive nearly mastered three balls, but its hard! that was really good, i enjoyed watching it.

crazy, how often can you hit that trick?

Thanks! Pretty often, but a lot relies on the set up throw from my friend.
