Object manipulation is a form of dexterity play or performance in which one or more people physically interact with one or more objects. Many object manipulation skills are recognised circus skills. Other object manipulation skills are linked to sport, magic, and everyday objects or practices. Many object manipulation skills use special props made for that purpose: examples include the varied circus props such as balls, clubs, hoops, rings, poi, staff, and devil sticks; magic props such as cards and coins; sports equipment such as nunchaku and footballs. Many other objects can also be used for manipulation skills. Object manipulation with ordinary items may be considered to be object manipulation when the object is used in an unusually stylised or skilful way (such as in flair bartending) or for a physical interaction outside of its socially acknowledged context or differently from its original purpose.

Object manipulators may also be practitioners of fire performance, which is essentially object manipulation where specially designed props are soaked in fuel and lit on fire.

Juggling balls, or simply balls, are a popular prop used by jugglers, either on their own—usually in sets of three or more—or in combination with other props such as clubs or rings. A juggling ball refers to any juggling object that is roughly spherical in nature.

Juggling rings, or simply "rings", are a popular prop used by jugglers, usually in sets of three or more, or in combination with other props such as balls or clubs. The rings used by jugglers are typically about 30 centimetres (12 in) in diameter and 3 millimetres (0.12 in) thick.

Juggling rings are easier to juggle than clubs, but harder than balls due to size and throwing mechanics. Because of rings' impressive appearance for their level of difficulty, they remain a popular juggling item.

Juggling is a physical skill, performed by a juggler, involving the manipulation of objects for recreation, entertainment, art or sport. The most recognizable form of juggling is toss juggling. Juggling can be the manipulation of one object or many objects at the same time, most often using one or two hands but other body parts as well, like feet or head. Jugglers often refer to the objects they juggle as props. The most common props are balls, clubs, or rings. Some jugglers use more dramatic objects such as knives, fire torches or chainsaws. The term juggling can also commonly refer to other prop-based manipulation skills, such as diabolo, plate spinning, devil sticks, poi, cigar boxes, contact juggling, hooping, yo-yo, hat manipulation and kick-ups.
