Pumice does not sink in water.
This is because pumice, type of lava, forms by the rapid cooling of lava that contains significant amounts of dissolved gasses. When the lava erupts the sudden decrease in confining pressure on the lava allows this gas to come out of solution. This makes lots of bubbles form very rapidly (the lava is essentially a foam).
As the lava cools very rapidly the bubbles are trapped in the solidifying material forming the hollow void spaces known as vesicles which result in pumices low density.
