See this here jug?
Well, what do you do with it when it's empty?
Throw it away?
Of course not!
You rinse it out thoroughly, fill it up with water and then mark on it SOAPY WATER with your trusty magic Sharpie pen. (random side note-did you know that my son served on his mission in the town that is called the Capital of Sharpies????)
Then you put it on your food storage shelf to save the soapy water to use when all he// breaks loose and we don't have water. It could be used to wash dirty dishes, clothing, bodies, etc.
Ok-well I thought it was an awesome idea.
