Juggling is generally assumed to involve multiple objects (like balls or bowling pins) flying through the air, being passed from hand to hand in an overhead arc, but contact juggling isn't like ordinary juggling.
However, when you watch a true master contact juggler at work it's every bit as satisfying as traditional juggling, and may cause the viewer to go into a contact juggling induced trance.
This new video from Kuma Films shows contact juggler AJ working his magic on a set of acrylic spheres that appear to dance around with a life of their own in AJ's magic hands.
