the only rock that floats, then sands your feet smooth as an apology
means A light, porous volcanic rock, full of trapped gas bubbles, used as an abrasive for scrubbing skin or smoothing surfaces.
from From Latin 'pumex' (pumice stone), which is thought to be related to 'spuma,' meaning foam — a fitting cousin, since pumice is essentially frozen volcanic froth, rock whipped so full of gas it forgets to sink. The word drifted into Old French as 'ponce' and then into English, keeping its airy Latin bones intact.
