I grew up next to an abandoned granite quarry. You could, and still can --though they are beginning rarer as the quarry is a bit of a tourist attraction, find super smooth, polished rocks. We would do this wringing with them all the time as kids. Never over until now did I wonder if anyone else had ever done this or if it had a proper name.

Maybe they were flat enough and cupped so that you could create a slight vacuum like you can with the palms of your hands? Would love a picture if you could get one.
