An unsettling thing happened at the Olympic diving pool on as the water inexplicably turned green just in time for women’s synchronized 10-meter platform diving competition.
The five-metre deep diving pool – which was a normal blue colour during the men’s event last night – appeared to slowly turn greener as the competition went on.
British Bronze medal winner Tom Daley noticed the change, tweeting: ‘Ermm… what happened?!’
An officials said they did not know what caused the trouble, exactly. But they declared the water had been tested and was not dangerous.
“It was an unsettling sight, appearing to become greener and murkier as the day went on, having been a lovely light blue on Monday,” he said.
The BBC commentators were so flummoxed by the pool’s colour that they asked an official what was going on, but they said they didn’t know.
