“Heat in a click” is an instant, portable and reusable heating pad. At the click of a button, the pad will reach 54c (130F), in a sealed plastic bag. On flexing the small metal disc inside the pad a molecular reaction is started causing the solution to crystallize. During the reaction (from liquid to crystal form) energy is released in the form of heat. The heating process can be initiated and the pad re-used again and again.
