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.

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.
