    Geology degree here - you identify some rocks by licking them. Licking most rocks will give you no information. But in a final, honestly, nobody would bat an eye if you licked all of them, just in case.

      I have to know, how was sanitation handled? did you each student have an individual sample, or were you all licking a communal rock?

        Individual samples and UV lights, though often there was a rock where multiple people would lick it. People probably don’t get sick from that often.
