The underwater cha-cha record has stood for nearly two decades, a testament to the unique and challenging nature of this dance form. While specific details about the original record-setting event are limited, the concept of dancing the cha-cha underwater has intrigued many.

In 1960, Timmie Rodgers released a single titled “Underwater Cha-Cha-Cha,” highlighting the dance’s appeal even in the mid-20th century.

The cha-cha is a timeless ballroom classic, and these people who danced it underwater set a world record that’s stood the test of time too.

The largest underwater dance class took place at the Sydney Olympic Park Aquatic Centre in Sydney, NSW, Australia, on 27 October 2006.

A group of 74 students, as seen in these amazing pictures, sunk down to the bottom of a swimming pool, armed with oxygen tanks and scuba gear, to dance for 13 minutes and 30 seconds.
