A mirror ball, often seen in dance clubs and at parties, is a spherical object covered in small, reflective mirrors. When light shines on it, the mirrors reflect the light in various directions, creating a sparkling effect that enhances the atmosphere of the space. Mirror balls are commonly used in conjunction with disco lights to create a festive and lively environment. These decorative items became popular in the 1970s during the rise of disco music and culture. They are typically hung from the ceiling and can vary in size, with larger versions often used in concert venues and events. Mirror balls are also associated with dance, celebrations, and nightlife.
