A River Runs Green

So, you’ve seen pictures of the Chicago River turning a brilliant shade of green every St. Patrick’s Day. You might be wondering, “Is it a mermaid’s pool party? A giant green Gatorade spill? Or perhaps the Windy City has a secret love affair with Kermit the Frog?” Nope, it’s actually a whole lot less magical and more, well, plumbing-related.

The Accidental Green Giant

Believe it or not, this annual transformation from murky brown to emerald green was actually a happy accident. Back in the 1960s, the city was trying to clean up the river, which was, let’s just say, not exactly a swimming pool. To track down where all the nasty stuff was coming from, they started using green dye to pinpoint leaks.

One day, a bright spark (or maybe just someone with really good eyesight) noticed that a plumber’s overalls were suspiciously green. And just like that, a tradition was born. Now, instead of using the dye to find leaks, they’re using it to turn the river into a giant, temporary green smoothie.

Green with Envy (or at Least Curiosity)

The dye used today is actually plant-based and environmentally friendly, so no worries about harming the river's ecosystem. It's more like giving the river a temporary green makeover than anything else. It's a pretty impressive feat, considering the river is, well, a river. Not exactly a canvas.

But let's be honest, it's also a bit of a party trick. It's like Chicago is saying, "Hey world, we can turn a river green! Wanna see us do it again?" And every year, the world says, "Yes, please!"

How to Green Your World (Probably Not Literally)

  • How to appreciate the Chicago River: Enjoy the spectacle from afar. Maybe grab a hot chocolate and a cozy blanket.
  • How to plan your green river viewing: Check the weather forecast. A sunny day will make the green pop even more.
  • How to be environmentally friendly: While the dye used is now eco-friendly, remember to respect the river and its surroundings.
  • How to dye your hair green (just kidding): Don’t try this at home. Your bathroom will probably never be the same.
  • How to celebrate St. Patrick’s Day: Wear green, eat corned beef and cabbage, and maybe, just maybe, take a trip to Chicago to see the green river.
