5-Minute Project: Hand Warmers

Instant hand warmers are great--just shake 'em up, and you've got spontaneous warmth to thaw your hands during the cold winter months. But they're awfully expensive, and not because they're complicated to manufacture. In fact, you can make them yourself in a few very easy steps.

3. Squeeze the smaller bag until it breaks open, to create a heat-producing reaction that will last 20 to 60 minutes.
