Do hand warmers react with water? The specific heat of water is large due to which it takes some time to change it's temperature. As soon as hand warmers get wet they will stop working till the water evaporates. As I said earlier water has large specific heat so it might take long to evaporate so the temperature remains same for the warmers.
