In short, pumice is less dense than water, so it floats. During the formation of pumice stone, air bubbles are incorporated into the stone itself. These air pockets make the overall mass of the stone much lower than you'd expect, and work like small floatation devices when the stone is placed in water.
Pumice, a volcanic stone with tiny air bubbles, is the only stone that floats in water.Pumice.Pumice, a volcanic porous stone, is lighter than water of equal volume because of all of the air bubbles in it, so it floats.
