Do hand warmers work?
It works like this. When you free the warmer from its plastic packaging, air enters the warmer’s porous pouch and reacts with iron and water (oxidizing), creating rust. This exothermic reaction releases heat energy. They generate heat for as long as the oxidization lingers, usually no more than a couple hours at best.
Are HotHands toxic?
