Mirror or disco balls are a spherical object or “mirrored ball” that reflects light directed at it in many directions, producing a complex starburst lighting display. It’s surface consists of hundreds or thousands of facets or mirror tiles that are usually made from real glass and range in size from 1/2 to 1”, and nearly all of approximately the same shape, and each having a mirrored surface. the larger mirror or disco balls are constructed from a fiberglass shell that is reinforced with a steel shaft to provide support, stability and safety
Usually mirror balls are mounted well above the heads of the crowd and is suspended from a mirror ball motor that causes it to rotate steadily on a vertical axis, and illuminated by spotlights or pin spots, so that stationary viewers experience beams of light flashing over them, and see myriad spots of light spinning around the walls of the room
