Uses I have found for the body warmer.
1. Cold football games.
2. Cold campouts.
3. My wife takes them to bed with her.
4. Long lasting localized heat for injuries or sore muscles

I have quite a few reasons for making this instructable (explained in later steps), but my main reason is I can't find any instructions anywhere else on how to make a sodium acetate hand warmer from beginning to end. I want others to share my passion and help me come up with ways to make these body warmers better. Ultimately I feel the best way to get more ideas flowing on the subject is to put an instructable together that described how to make a decent sodium acetate body warmer.
If you would rather watch how to make it than read it, then go to this youtube video. (Note: I doesn't include instructions on how to make the insulated bag).
