Description
Hot and cold compresses. These contain a chemical (ammonium nitrate for cold, magnesium sulphate for warm) and an inner bag containing water. By squeezing the outer bag, the inner bag is ruptured and the water mixes with the chemical. In the case of ammonium nitrate, the reaction is endothermic and for magnesium sulphate the reaction is exothermic.
