Originally shared by Google Science FairLake Hillier is located in Western Australia. The pink color of the lake is permanent, and does not change when taken out of the lake. It is still unknown why the water is pink. Some researchers suggest that it is due to organisms living in the salt crust deposits surrounding the lake. Despite the unusual color, the lake exhibits no known adverse effects upon humans. https://www.googlesciencefair.com/
