How do silica gel packets work?
Silica gel is a desiccant that can hold 30 to 40% of its weight in water. Each silica bead has many tiny interconnected pores, resulting in high surface area. The tiny pores also hang on to moisture through capillary condensation, which means that, even when saturated with moisture, the beads seem dry.
