During the pool diving competitions, fans were surprised to see the water gradually go from blue to sickly green as the day went on.
Team GB diver Tom Daley
summed up the thoughts of the watching world after he had completed his heats.

Many Twitter users suspected it was an Irish prank, or a late nod to St Patrick's Day.

However, the actual reason for the water to turn 40 shades of green was pretty simple. Bloody algae.
Mario Andrada, a spokesperson for the Rio organising committee, explained to reporters, last night, that said the green tinge was caused 'by a proliferation of algae'.
Typical algae, proliferating around like it owns the place.
The stillness and heat of the day didn't help matters none.
Andrada commented:
"This was because of heat and a lack of wind. We did all the chemical tests. The pool will be blue tomorrow.
"If it were green and yellow, we would know it was a patriotic thing,"
One to watch closely today as the pool action continues.
Andrada can then go back to figuring out if a bus carrying media through the Deodoro zone, last night,
was hit by stones or bullets.
