In many of the products that we purchase at local stores, we will find small silica gel packets enclosed. They are often present to keep moisture from accumulating and ruining whatever is in the packaging, even if it is on the shelves for an extended amount of time!
On the side of most silica gel packages is a note telling you to throw them away. Once you learn of all of the beneficial ways you can use silica gel packets, however, you will never throw them away again! In fact, you will ask your friends to keep theirs for you as well.
