If you suffer through 5 months of winter like I do, you'll be familiar with hand warmers. But did you know you can make your own? For supplies, we only need 4 'ingredients'. They are....
- one large ziplock bag
- one smaller ziplock bag
- some calcium chloride ice melter pellets (available at places like Lowes)
