TIL that door knobs made out of brass automatically disinfect themselves in about 8 hours through the oligodynamic effect

Fascinating. Good post.

Silver does this also, which was probably handy for silverware before antibacterial dish soap was invented.

That’s mentioned in the article as well. They also stated that a copper or silver container can disinfect a pot of water in a few hours. im gonna add a copper vessel to my emergency provisions now. @yourunclejingo you may find this stuff interesting too.

Its almost like our ancestors did shit that made sense even if they didn’t always fully understand why.
