From the article:
> We might know water as H2O, forgetting everything that’s dissolved in it. For example, a small vial of the Kidd mine water transferred in 2020 to Ingenium—a Crown corporation that runs the Canada Science and Technology Museum in Ottawa—features sediment at the bottom. That’s iron oxide, which precipitated from the water after exposure to oxygen from the air.
- DemocracyFTW2 4y agoI did read that sentence and its among the few instances where the article goes a little into the details of the evidence rather than the circumstances of their acquisition, like that journey down the mine shafts. The introductory sentence is fine and a good reminder given the likely audience. It does a good job for setting the stage. The next two sentences then thrash that hope by telling lots of irrelevant detail in the hope to tell an interesting story, and we're left with, ok, there's a certain amount of iron oxide in the water, which fell out because of contact with oxygen. This is literally what can happen to you when you bore a meter-deep well in your garden; in regions with iron in the ground, the water that comes up will have lots of iron oxide in it that will color everything in a reddish hue when drying. How does that address any one of my questions?
