Silica gel packets: unexpected household uses beyond packaging

Silica gel packets, often discarded after unpacking, are desiccants that absorb moisture and can protect shoes, electronics, documents, and metal tools from humidity damage. They also help preserve flowers. While generally non-toxic, they pose a choking hazard and lose effectiveness once saturated. Experts suggest reusing them in enclosed spaces, but note they cannot replace professional drying for water-damaged devices.
