The periodic table just called—it wants its fashion sense back! Most metals are boring gray lumps, but bismuth (element 83) is the flamboyant drama queen of the periodic table. While "every single metal element" looks like a minimalist gray building, and even the supposedly fancy "copper and gold" just manage some basic color coordination, bismuth shows up to the element party with its signature iridescent rainbow crystals that would make a unicorn jealous. Bismuth naturally forms these geometric, stair-stepped crystals with an oxide layer that creates a spectacular rainbow effect through light interference—basically the metal equivalent of putting Christmas lights on your house and cranking it up to 11. Chemistry doesn't have to be dull when you've got the metal equivalent of a Lisa Frank folder!
