CHICAGO (WMAQ) – The luck of the Irish is strong in Chicago.
For the past 56 years, the river has been running green in honor of St. Patrick’s Day.
On Saturday, boats took to the water, and with a little luck, the river turned green.
It’s an operation handled by the descendants of two Chicago Police officers first tasked with turning the water green in 1962.
The mayor originally wanted to turn all of Lake Michigan green, but it was just too big.
It was a similar scene Saturday in Tampa, Florida as they dyed the Hillsborough River green. It’s a part of the 8th annual Mayor’s River O’Green Festival.
As for exactly how the process works, well, that’s a closely guarded secret.
The men who know the recipe will only say the substance, called “leprechaun dust,” does not harm humans, animals or the environment.
