Nearly 2,000 people floated in a line in a Salty Lake in Argentina, setting a new Guinness World Record for the most people floating while holding hands. Members of the Guinness book of records certified that 1,941 people floated simultaneously for 30 seconds in Lake Epecuen, located to the southeast of the Buenos Aires province.

The previous record was set on June 28, 2014 in Sun Moon Lake in Taiwan, when 634 people floated in line, using flotation devices. Participants in Argentina floated unaided in Lake Epecuen, due to saltiness of the water. The lake is Hypermarine and contains almost 10 times more salt than the sea, helping participants to float naturally.

The world record was set within the frame of a local Thermal Tourism Festival. Buildings from the town have now risen above the water and the area has again become a tourist attraction with visitors enjoying its Apocalyptic atmosphere.
