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. Tricks that can be performed include the Candlestick, Bird's Nest and Crescent Moon Connections. 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). 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. Types. 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.
