How Do Chemical Hand Warmers Work?

• Introduction
  Whether you are camping, hiking, skiing or snowmobiling, there is one piece of equipment that should always be carried with you. That equipment is the chemical hand warmer. Not only is it a great thing to have to keep your hands warm when out for recreational activities, it can also be a lifesaver to keep your hands or feet warm during and emergency where you may be stuck in the cold for an extended period of time
• Ingredients
  Chemical warmers are made up of a combination of iron, activated carbon, cellulose, vermiculite, water and salt. These ingredients are wrapped in a container that keeps out any oxygen from interacting with the ingredients inside the warmer
• The Reaction
  Chemical warmers work by a chemical reaction. When the warmer is unwrapped, oxygen is allowed to mingle with the ingredients inside the warmer. When the oxygen hits the iron in the warmer, it causes the iron to oxidize. The chemical reaction releases energy in the form of heat
• Salt and Polypropylene
  The salt in the chemical warmer is an important ingredient because it works as a catalyst. A catalyst is a substance that speeds up a chemical reaction, or in this case the reaction between the oxygen and the iron. The polypropylene works by allowing the oxygen to circulate without evaporating all of the water
• Carbon and Vermiculite
  The carbon acts as a dispersant agent. This allows the heat to spread throughout the chemical hand warmer equally. The vermiculite works by insulating the hand warmer. This keeps the heat from escaping too quickly and allows the chemical warmer to remain warm longer

How to Reuse Chemical Hand Warmers

• Wrap the used handwarmer in the cloth. This shields it from damage and overheating. Make sure the cloth covers the handwarmer completely. An old sock or bandanna will work well
• Place the wrapped handwarmer in the pot. Fill the pot with water and heat it on the stove
• Boil the handwarmer in the pot of water for several minutes. This will begin to reverse the chemical reaction that crystallized the sodium acetate. Boil until the sodium acetate has turned back into a liquid
• Remove the handwarmer from the pot and store it for later use. When you're ready to use it again, click the disk to activate it, or follow the instructions that came with the handwarmer. It should provide heat for anywhere between 30 minutes to several hours
