Contact ball juggling is a form of juggling art which uses heavy acrylic balls for manipulation and focuses on the movement of balls in permanent contact with the body.
Having little in common with "toss" juggling, it most typically involves the rolling of one or more transparent acrylic balls on the hands, arms and body to create visual illusions, such as that of a ball fixed in space.
"Body rolling" is one type of manipulation without the prop(s) ever being thrown into the air. This includes tricks such as headrolling, isolations and the butterfly.
Another type of contact ball juggling is the "Palm spinning" this is created with the manipulation of two or more spheres in each hand wherein at least one sphere is always in continual motion.
Spheres may be transferred from one hand to another to form graceful and fluid patterns, but rarely are they ever released into the air.
