Can I lick it?

“Can I Lick It?” is our interdisciplinary Chaos Lab series where we ask the only question that matters: can you lick it? We take everyday (and not-so-everyday) rocks, minerals, and mystery substances and put them to the test—because we’ve gotta know if the science says it’s safe. Sometimes licking is diagnostic. Sometimes it could kill you. Sometimes the only answer is just… how? Equal parts geology, microbiology, and feral humor—this is Chaos Lab at its finest.
