What are Warmers and how do they work?
The secret is simple: Magic. Okay, not really. People often refer to air activated warmers as chemical warmers, based on the exothermic chemical reaction which creates the heat. We prefer the term elemental warmers, since the ingredients are all elements that occur in nature! No bubbling-flask chemicals here, just elements of the earth like iron, carbon, water and salt. The remaining ingredients are cellulose, commonly found in cotton, and vermiculite, a natural mineral.
