Disposable hand warmers turn up the heat in your mittens by means of an exothermic reaction that, in essence, just creates rust. Each pouch typically contains iron powder, salt, water, an absorbent material, and activated carbon. The activated carbon helps to evenly disperse the heat produced, which can average 135 °F.
How do HotHands stay hot?
First, some basics. Most disposable hand warmers contain a mix of iron, water, activated carbon, vermiculite, cellulose, and salt. Once exposed to air, the iron oxidizes and releases heat in the process. Even a small hole can let in sufficient oxygen to keep the reaction going and render your hand warmer cooked.
