Don’t throw these away: Silica gel bags. They’re usually found in a box when you buy new shoes or a camera. Usually, we throw them out.

Silicon dioxide dries out anything around them. Non-toxic, not poisonous, they do pose a choking hazard. Keep them away from children. Here’s what you can use them for.

1. Throw them in your gym bag and you can prevent bacteria or mold from growing. It also gets rid of nasty odors.

2. Save a wet phone. It’s more effective than rice. Put the phone in a jar full of the bags.

3. Save old photos. Put a few of the bags in a box of old photos. It saves them from sticking together or getting ruined.

4. Defog your windshield. Put a bunch of the bags under your windshield. It takes care of the fog and saves precious time.

5. Extend the life of razor blades. The bags absorb the moisture from your blade.

Think twice before throwing away.
