I know, I was surprised too. Some dudes in Canada decided to hurl a couple of bottles of flouroscein into the Goldstream River, turning the whole thing bright flouro green. Way to one-up the Old Testament, Canada. I thought you guys were supposed to be nice.
Interestingly, the fluorscein isn’t going to mess up the ecosystem too badly, on the grounds that it is water-soluble and non-toxic, but the Wikipedia says that it can cause ‘nausea, vomiting, hives, acute hypotension… cardiac arrest and sudden death due to anaphylactic shock’ in humans. So I guess that kid who got dared to dive into the bright green river is rethinking stuff at the moment.
