Make Your Own Instant Hand Warmers in 5 MinutesYou know those expensive instant hand warmer packs used to thaw frozen hands out in the winter? No need to buy them. Make your own instant hot packs with ziplock bags and just one thing from the hardware store.

Instructables user junits15 posts the easy instructions. You need a large ziploc bag, a smaller one, some water, and calcium chloride ice-melt pellets from the hardware store.

Fill the large bag a quarter of the way with the ice-melt pellets. Fill the smaller ziploc bag halfway with water and seal and then put it inside the bigger bag, squeeze out the excess air and seal. Now, squeeze the smaller bag until it breaks open and the water mixes with the ice-melt pellets, which should create a warming reaction between 20 minutes and an hour according to PopSci (how long will depend on how many pellets you use).
