Found this in my parents backyard, no idea what it is? It has no seams or anything. It has no features at all. Totally smooth. Very light weight. Doesn't seem hollow tho. It's about 3 inches long.
https://en.m.wikipedia.org/wiki/Oligodynamic_effect The oligodynamic effect (from Greek oligos, "few", and dynamis, "force") is a biocidal effect of metals, especially heavy metals, that occurs even in low concentrations. In modern times, the effect was observed by Carl Nägeli, although he did not identify the cause.[1]Brass doorknobs and silverware both exhibit this effect to an extent.
It's not that the metal bar actually kills orders. It's that the smell of butthole on it gets on your hands/fingers and masks the bad smells from everything else.
It’s bunk, but you’re not dissolving metal. Is no different than touching your stainless steel pans/utensils or your stainless steel sink. The idea is sulfuric compounds on your hand bind to an oxide layer on the steel, and then that washes off the steel with soap and water.
