A sponge is a porous or absorbent material because it can soak in liquid into itself. Its porous body, which has many holes, allows water to penetrate it. The sponge’s porous bodily material, filled with pores, allows liquid to pass through easily, and so is often used for cleaning purposes since it also retains water.
