No one celebrates St Patrick’s Day harder than the US National Whitewater Center in Charlotte, NC. Every year, a “leprechaun” transforms their whitewater course from blue to green. The event is known as the Green River Revival and is accompanied by many other festivities on and off the water.
The organizers use a special non-staining, non-toxic, biodegradable dye that breaks down via sunlight and their built-in filtration system. While the water will be bright green starting at 1 pm on March 14, it will be clear again by the next day.
