Step 1: In The Beginning.
I was needing a way to preserve my ammunition for long term storage. Given the fact that my basement is almost always damp and very humid in the summer months it posed a real challenge to keeping the ammo fresh. After gleening over the Mrs. pantry one day and seeing rows upon rows of canning jars the Foodsaver idea popped into my head. I have been using this method of storage for over 5 years with great results. After my last reloading session I decided to do an Instrucable on it.
Let's take a look at the pros and cons of using canning jars before I get berated for using glass containers.
- Impervious to moisture and humidity
- Effective oxygen barrier
- Contents can be easily seen
- Can be stored in harsh climates including underground
- Canning jars WILL ALWAYS be needed for food preservation
- Hard to transport
- Harder to stack
Once filled, the benefit of using glass outweights the negatives as a storage container, especially if the jars are going to be used in a supply cache.
Step 2: Testing The Foodsaver Vacuum
Both jars have almost an equal amount of marshmallows. Once the Foodsaver is turned on and a vacuum is created, the atmospheric pressure is reduced inside the jars. This vacuum allows the marshmallows to expand.
