Because I am Aversive to Dying

To increase humidity in your refrigerator, fill a plastic milk jug or 2-liter soda bottle with water and store it in the refrigerator with the cap off.

Good grief, that will ice up the cooling coils. If you have a self defrosting refrigerator as most people do, it'll cost you ( pulls number out of ass) 50% more to run.
