The Water in the Olympic Diving Pool Turned Green

The water in the Rio Olympics diving pool has turned green ahead of the women’s synchronized diving final Tuesday night.

British diver Tom Daley, who won bronze in the men’s synchronized diving Monday, tweeted a picture showing the green diving pool compared with the blue water polo pool. As of Monday night, the diving pool had been the same shade of blue as the other Olympic pools.

The International Olympic Committee did not immediately respond to a request for comment.
