I put this on an unlabeled squirt bottle once at work. It was wrong to do because technically it's an OSHA violation for being improperly labeled because it was just in sharpie and not a standard label. But it was night shift I was bored and the bottle was already unlabeled so it was already out of compliance. Why not write on it?

A week or so later I heard people talking about this squirt bottle that said dihydrogen monoxide. Two safety guys were there so I didn't take credit for my shenanigans based on the reception not being great.

I said I think it's just water, but the chemical name. Ya know? Nope, they didn't get it. The kind of doubled down and started talking about things in that link because they "researched the name" and it was actually harmful.

It was a strange experience.

Because people don't use that terminology when referring to a time period within a majority of living people's lifetime.
