Q: Please critique Jack Sparrow's geology taste test technique? A: Terrible. First: WAY too much tongue. It's test, not a snack. Second: Any rock tough enough to weather into that nice smooth shape isn't one where taste is diagnostic. All you'll get is the seawater coating.pic.twitter.com/PvlQZn3Y37

Star Wars: "Well, actually..." follow-up: https://twitter.com/mikamckinnon/status/1030725051732172800 … Doctor Who: Sediments were dead people, so taste test is EXTREMELY diagnostic. Fossils stick to your tongue; desiccating/sticky texture. Other pop culture geo taste tests? Ping with gif/clip/still for critique.

Mika McKinnonVerified account @mikamckinnonThe number of Last Jedi haters in my mentions telling me I’m wrong is kinda delightful. Like, I did this EXACT sequence of actions last time I was in Utah when to figure out if I was in sand or salt. Hating the movie (fools) doesn’t make the geo less plausible. https://twitter.com/mikamckinnon/status/1030205382243708928 …Show this thread7 replies 43 retweets 531 likesShow this thread -
Q: ...but won't it kill you if you lick the wrong rock? A: Do not lick anything with mercury, arsenic, or lead. A few others can still kill you (lookin' at you, villiaumite, torbernite, & chalcanthite), but that's a good starting point.

Bad minerals to lick: Anything that smells like garlic (arsenic). Even handling is sketch thanks to carcinogenic, neurotoxic powder; burning is bonus bad news. Arsenopyrite: arsenic + sulfur Orpiment: arsenic + sulfur Hutchinsonite: sulfosalt of thallium, lead & arsenicpic.twitter.com/jDOZqVhrt1

Anything with mercury is a slow, painful way to die. Cinnabar: gorgeous mercury sulphide; also the most deadly mineral on Earth. Do not lick. Do not even touch. Considering it oxidizes to methyl mercury & dimethyl mercury, don't go near it, either. Just turn around. Now.pic.twitter.com/pYqPbu6mKj

Chalcanthite: water-soluble copper sulfate. Taste is diagnostic (sweet metallic) yet it leads to copper poisoning. So, don't lick, but if you're going to, make it a quick tongue-touch-retreat to minimize exposure.pic.twitter.com/5YgF8Wu4Bj

Anything with lead is a no-go for licking unless you love the long-term violence of lead poisoning. Galena: lead. Like, all the lead. So much lead. Don't eat it or huff it. Just smash it with a hammer -- if you get a bunch of smaller cubes, yay, it's galena! Done.pic.twitter.com/RJor2WqusG

Asbestos (serpentine, crocidolite, grunerite, tremolite, anthophyllite & actinolite) is not inherently deadly to lick, except it'll splinter into your tongue like fibreglass & you'll huff shards into your lungs for long-term damage. Overall, bad candidate to lick (or pet).pic.twitter.com/fRo4OwagCC

Torbernite: uranium. It's radioactive. Licking anything radioactive is a bad idea. It also has copper for a bonus copper poisoning. Pitchblende (uraninite) & autunite are also bad choices to lick, but great choices for uranium ores if you need to build a bomb from scratch.pic.twitter.com/PCkQW28DAb

Villiaumite looks seriously tempting, but is a VERY BAD IDEA. It's cherry red, very soft (scratch with your fingernail) & fluoresces under UV light, so licking is unnecessary for ID anyway. Licking screws up breathing, heartbeat, circulation, nervous system, & skin. Just no.pic.twitter.com/qYqaIKbUyL

It looks like cake. The mineral looks like cake. You're just saying this so there is more cake for you. I am eating this.
