How Do Hand Warmers Work?

The hand warmers work through a simple chemical reaction which causes rusting inside the packet once it's exposed to air. The warmer contains water, cellulose, iron, vermiculite, activated carbon and salt. When exposed to air, these things cause the iron to rust at slow rate, and produce heat.
