Mirrors. The perfect surface for any party! We partiers owe a huge debt to the first person who thought to take thousands of them, glue them to a sphere and stick that sphere on the ceiling in the service of funky tuneage. Disco balls have been in the United States since 1917, but it's only been three decades since these spherical, mirrored balls sealed the deal as a central accessory to the disco era. Fast forward to today, and the love affair hasn't stopped.

Made from aluminum, fiberglass and sheets of glass mirror tiles, every dance floor benefits from some dazzling disco ball action. And because mind-blowing visuals have become a standard part of the festival experience, they fit right in; even with all the jazzy, new technology, people still go nuts for a good ole' shiny disco ball.

Cement Mixer Disco Ball, Festival of Lights, Lyon, France

No one ever said disco balls had to be just a ball, right? French artist Benedetto Bufalino mixed it up at this year's Festival of Lights with his interpretation of the disco ball design genre. Judging by the number of people who turned up to dance in the streets, Bufalino's creation will be cemented as an all-time great.

"The World's Biggest," Bestival, Dorset, United Kingdom

You can always count on Bestival to outdo itself. After the world's largest fancy-dress party in 2013, The Guinness Book of World Records came to the Isle of Wight in 2014 and confirmed that Bestival's disco ball was indeed record-breaking as the worlds largest. Today, in 2017, the record still stands.

Disco Shark, Coachella, Indio, California

Disco Shark made its 2014 debut in Coachella's Yuma Tent. It was an instant hit and, recognizing an opportunity to raise awareness for endangered sharks, artist and conservationist Kevin McHugh returned in 2015 with a campaign to raise money for shark conservation charity Oceana . The 8-foot long shark is composed of fiberglass and more than 6,000 mirrored tiles.

"Mirror Mirror on the Ball," What the Festival, Durfur, Oregon

WTFers flock to the silent disco under "Mirror, Mirror on the Ball" when action at the WTF Stage, Effin Stage and Splash Stage goes quiet for the night. Looking at a spinning disco ball for too long feels like chasing your own tail, and this is one that sucks us in.

Sherwood Forest, Electric Forest, Rothbury, Michigan

Sherwood Forest's  epic spectacle is just one of the reasons why people love Electric Forest so damn much. Trees make the perfect surface for bouncing light, and as the disco ball goes round and round and round and round, you won't even care that your eyes aren't sure where to look.
