Aerial hoop

The aerial hoop (also known as the lyra, aerial ring or cerceau/cerceaux) is a circular steel apparatus (resembling a hula hoop) suspended from the ceiling, on which circus artists may perform aerial acrobatics. It can be used static, spinning, or swinging. It can be single point or double point. Tricks that can be performed include the Candlestick, Bird's Nest and Crescent Moon

Lyras hang down from their rigging using a type of hanging material called a spanset. Tabs are the connection points where the aerial hoop attaches to the rigging. Most aerial hoops connect at either one point (single tab configuration) or two points (double tab configuration). Though there are some aerial hoops that do not have tabs, and are referred to as tabless, meaning the spanset is tied directly onto the hoop rather than on a tab. The number of tabs an aerial hoop has will depend on how it will be used, the intended effect, and the performer's comfort level. All rigging hardware that connects to an aerial hoop must be safety tested and certified to ensure the performer is safe.

Aerial hoops can be hollow or solid. Lighter hoops will spin more easily; once a solid hoop gets momentum, it will stay spinning for much longer. Sometimes aerial hoops have crossbars or hand or foot loops to aid the performer.
