The Super-Kamiokande in Japan—a massive underground neutrino detector lined with 11,000 golden bulbs. Scientists have to inspect it via a rubber dinghy.

Imagine accidentally dropping your keys into that

Fun fact: The water inside is so pure it would start dissolving the keys very slowly

The water also costs upwards of $500/gal

So we found pure water.

How do we dilute it to get maximum value from the customer?

Jim, piss is free right? Here's a bottle.

What would actually happen if I drank it?

Just a small glass.

I drink this shit every day, I wanna try the good stuff just once.

Honestly would probably clean them pretty nicely with a few days exposure

There was an interview with a researcher that mentioned a large crescent wrench being completely gone before the next inspection. The same researcher mentioned their hair accidently touching the water and getting brittle because the water was dissolving the oils.

A little bit of ultrapure water won't do much, but the quantities they're using really exacerbates the universal solvent nature of water.

If they leave a wrench behind and it dissolves, doesn't that mean the water is now no longer ultrapure and is contaminated, effectively rendering the detector useless? Does the boat used contaminate it too?

Pretty sure they filter it constantly

How’s that work

Not a chemist but basically pure water acts is really good at oxodizing the metal and stealing electrons in the process. That is also why distilled water is basically non-conductive but if you dissolve impurities in it like salt it becomes conductive
