Silica Gel, SiO2, is essentially a synthetic, microporous form of sand. It's produced in small, irregular beads that contain thousands of microscopic cavities. These cavities create a low vapor pressure inside it, which makes the beads hygroscopic - i.e. they tend to adsorb water molecules from the humid air, which has a higher vapor pressure.
