Contact juggling is a form of object manipulation that focuses on the movement of objects in contact with the body. It involves the rolling of one or more objects without releasing them into the air. It is divided into three main techniques: Body rolling means manipulating one or more props around the hands, arms, and other parts of the body.
Palm spinning means manipulating one or more balls in the
open hand so that at least one ball is in motion. Balls may be in
both hands or transferred between hands to form graceful and fluid
patterns, including rotating a pyramid made of four or five balls
in one hand.
Isolation refers to the manipulation of a ball so that it
appears to be suspended in place, creating the effect that the
ball is still while the performer moves around the ball.
