The winter holidays are now behind us, but it seems I missed one of the biggest pranks of 2010 – the 
green river of Goldstream Park.
It happened on December 29, 2010, in Victoria’s peaceful Goldstream  Park. The waters of the river suddenly became neon green, and everyone  passing by it rubbed their eyes to make sure what they were seeing  wasn’t just an illusion. It was very real, but was it that made  Goldstream River look so alien-like? After an hour or so, the  fluorescent coloring vanished, but the questions about the bizarre phenomenon remained unanswered.
After analyzing the neon-green water, the local Environment Ministry  said it was the result of a chemical called “fluorescein”. Neither the  substance itself nor its products of degradation are toxic, and experts  believe that fish and their habitat were not affected, judging by the  concentration and flow rate of the river.
Authorities haven’t yet identified the culprits, but believed the dumping of fluorescein in the Goldstream River was just a holiday season prank.
