I finally tried that 'rock identification by licking' thing I saw online
I mean, I always thought it was just a dumb joke, like something from a cartoon. But last week I was out near Sedona and found this weird gray rock that felt chalky. I remembered a video saying to lick it to see if it stuck to your tongue, which means it's a shale. So I did it, and it totally stuck, just for a second. It was a shale, which made sense given the area. Has anyone else actually tried this, or is it just a weird trick that sometimes works?
