Have you ever gone to a football game and frozen your butt off? While at the game you happen to have brought those little charcoal throw away handwarmers. You pull it out, open it up, and shake the daylights out of it trying to get it to produce some heat. Normally the amount of heat you get by shaking the bag warms you up more than the little bag ever will. The last football game I went to was 30 F so I took one of my body warmer along and it produced 5+ hours of heat! If your looking for a better solution to help keep you warm during those freezing football games (or other cold outdoor activities) then this is the instructable for you.
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
5. Cold car rides to and from work
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).
