How does Chicago dye the river green for St. Patrick’s Day?
The Chicago River Dye is the work of Chicago Plumbers Union Local 130. They use a proprietary dye to turn the Chicago River green in three boats, two with the secret sauce and a hunter ship to mix it up. The dye is basically a food coloring concocted by plumbers years ago to help detect leaks in buildings.
How long does the Chicago River stay green?
The dye will stay in the river for 24-48 hours.
What will the weather be like in Chicago on Saturday morning?
Saturday will be sunny but very cold and windy, with wind chills in the single digits only. The temperature is expected to reach 20 degrees by the time the river dyeing begins at 10 a.m., but it will only be 5 degrees.
