Ever find those little silica gel packets when you buy something new, like a new computer, a wicker basket or even inside bottles of vitamins? They are designed to absorb moisture and protect items from rust, but they are also nearly impossible to recycle. The good thing is that they have a million uses around the house. Leave them in a box of old photos, baseball cards or any paper matter to prevent humidity from attacking printed items. Leave some inside toolboxes and camera bags to prevent rust on expensive equipment. If you save seeds to plant in the spring, drop a few packets in with the seeds to protect them from mold during the fall and winter months.
