Unicef and Cosmopolitan have come together this time to promote a clean environment and water. The concept was “dream water”. And they’ve asked Seohyun, Yuri, and Sooyoung to help ’em out in the task!

On the 11th, the girls headed on over to Photographer Audition Survival program ‘Photographer’  to pose as models. It was basically a “survivor” program because SNSD was posing/competing against other celebrities including Jang Wonseok and Im Jaewook and plenty others.

Prize? 10 million won, full set of Canon Cameras (oh…man am I jealous or what.) and opening the photo exhibition.

The winner is of course, the girls! Episode will be airing on the 29th at midnight.
