Bobbi Cook has a need method she is trying and wanted to share. Ask her if you have questions.
Did you know that you can store dry goods in PETE plastic containers? I guess the church is doing this in third world countries where they need to store food, but don't have canneries. Here's a link that tells you how http://www.instructables.com/id/Storing_Bulk_Dry_Foods_in_PETE_Bottles_using_Oxyge/. The only other thing that I heard to do that this person didn't is to use packaging tape around the lid of the container.
