Hawaii wildlife refuge pond mysteriously turns bubble-gum pink. Scientists have identified a likely culprit.

A pond in Hawaii has turned so bubble-gum pink it could be from the set of "Barbie," but the bizarre phenomenon is no cause for a dance party. Drought may be to blame for the strange hue, scientists say, and they're warning against entering the water or drinking it.

Staff at the Kealia Pond National Wildlife Refuge on Maui have been monitoring the pink water since Oct. 30.

"I just got a report from somebody that was walking on the beach, and they called me up like, 'There's something weird going on over here,'" said Bret Wolfe, the refuge manager.
