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.
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 comfortability level. Double tabs do not spin and have a trapeze-like swing. Single tabs swing along more than one axis.
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.
Building Aerial Hoops
This article articulates how someone built an aerial hoop-- the key tool is a hydraulic pipe bender.
