How Do They Keep That River Green?
So, you’ve seen the pictures, right? The Chicago River, a normally drab, urban waterway, magically transforms into a shimmering emerald ribbon every St. Patrick’s Day. It’s like someone accidentally spilled a giant vat of green Kool-Aid into it. But how, pray tell, do they pull off this aquatic illusion? Let's dive in!
The Green Guru of the Great Lakes
It's not leprechauns, folks. The mastermind behind this annual hue change is actually the Chicago Journeymen Plumbers Local 130. These are the unsung heroes, the river's green guardians. They've been dyeing the river for over six decades, and let me tell you, they’ve got this down to a science (or at least a closely guarded secret).
The Science (or Magic?) Behind the Green
Originally, they used a fluorescent green dye that stuck around for days. But environmental concerns raised an eyebrow or two. So, they switched to a more eco-friendly option: a vegetable-based powder that turns green when mixed with water. Think of it as a giant, aquatic chemistry experiment.
The process is actually quite low-tech. Boats equipped with special dispensers spread the orange powder across the river. It's a bit like sprinkling fairy dust, but without the magic wands. Within a couple of hours, poof! The river is green.
A River Runs Through It (Green)
Now, you might be wondering, "Is it safe?" Good question. The dye is non-toxic, so no worries about aquatic life turning into Kermit the Frog. However, some environmental groups argue that it's a symbolic gesture of the river's past pollution problems. But hey, it's a tradition, and traditions are hard to break, especially when they involve such a vibrant color.
