It's not easy being a green River

Ein paar Prankster haben den Goldstream River in British Columbia in fluoreszierendes Grün gefärbt. Von CTV News: „Lab results showed that the bright green hue was caused by a synthetic, organic compound called fluorescein, which is most commonly used as a fluorescent dye tracer in fluids. Ministry staff say the substance is water soluble and don't think any fish or fish habitat were harmed by the incident.“
