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 as 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 or for a physical interaction outside of its socially acknowledged context or differently from its original purpose.
