How to Make Chemical Hand Warmers

Chemical hand warmers are a must-have when spending time outdoors in cold weather. They are a great way to protect hands and feet from frostbite whether you are enjoying nature or find yourself trapped in inclement conditions. With a few common household items anyone can save money and a trip to the store by making their own chemical hand warmers. This guide will show you how in simple, easy to do steps.

Put sodium acetate in a saucepan with just enough water to dissolve it.

Heat the liquid until it is almost boiling.

Stir in more sodium acetate until solid material begins to accumulate in the bottom of the saucepan. Stop immediately.

Pour the liquid into a glass container. Make sure none of the solid material is in it.

Refrigerate the container for 30 to 60 minutes then make sure it is still in liquid form. This will happen only if none of the solid material is in the container. Keep it refrigerated until you are ready to use the hand warmer.

When you are ready for the hand warmer, dip a toothpick or the edge of a spoon in the sodium acetate powder and put some in the container with the liquid. It will turn into a solid and begin to heat up.

Place the solid in a plastic bag. Now it is ready to be used.


  • You can re-use the hand warmer by placing it into a sealed plastic bag and boiling it in water. Make sure all of it is melted, or it will quickly turn back into a solid. Then just cool it in the refrigerator and save it until you are ready to use it again.
