If its blue color faded quickly, the milk was contaminated with bacteria, but if it remained blue, the milk was considered relatively clean.This safety test now is largely obsolete. But it works thanks to methylene blue’s chemical superpower, which is that its molecules can swap electrons with other molecules, like a tiny battery charger.

That same chemical superpower enables some of methylene blue’s medical uses. Most significantly, doctors use it to treat a rare blood disorder called, in which hemoglobin, an iron-rich protein in red blood cells that carries oxygen, takes on a different form that can’t do the job.
