If you attended or competed in the diving competitions at the 2016 Summer Olympics in Rio over the last two days, you probably noticed a change in color of one of the pools.
One of them was green Tuesday, and no one has been able to find out exactly what happened.
Luckily, the water was tested and no health issues reportedly were discovered. Still, it’s a pretty strange sight.
