TIL: Bismuth also does the water thing where it‘s less dense when solid
wild
@halcy bismuth is also *technically* radioactive but so little that it's basically undetectable: "The metal's only primordial isotope, bismuth-209, undergoes alpha decay with a half-life about a billion times longer than the estimated age of the universe" (wikipedia)
also it's one of the metals with the lowest melting points, which makes the "less dense when solid" thing also harder to test
and it's super iridiscent (image source: https://en.wikipedia.org/wiki/File:Wismut_Kristall_und_1cm3_Wuerfel.jpg )
all-around weird-ass metal
@pcy bismuth is one of the materials of all time
i do kind of want a bismuth crystal, enough that i‘d impulse buy one from a store but not enough I‘d order one online
@pcy i just went to read more about bismuth and the Wikipedia page is just casually like „oh yeah bismuth is also the most diamagnetic element. also, the bismol in pepto-bismol comes from bismuth because it‘s a main ingredient in that since it’s so nontoxic“
What the heck!
