    The diving pool at the Olympics has mysteriously turned green

    Many people highlighted the problems with the water outdoors in Rio leading up to the 2016 Summer Olympics.

    On Tuesday, the attention quickly turned to the water in the diving pool, which seemed to change from a cool blue to a slime green overnight.

    Among the people to notice was diver Tom Daley from Great Britain, who tweeted a photo of the stadium Tuesday afternoon.

    BBC Sports journalist Nick Hope tweeted a statement saying that venue officials had tested the water and there was "no risk" to athletes' health.

    However, the release also stated that officials were "investigating the cause of the situation."

    Photos from Monday clearly show that the diving pool was a very different color.
