Heat in a Click pads contain a solution of Sodium Acetate (a form of Salt) in a sealed plastic bag. Upon flexing the small metal disc inside the pad a molecular reaction is started causing the solution to crystallize.Starting this chain reaction causes the entire solution to solidify. During the reaction from liquid to crystal form, energy is released in the form of heat. Gradually the heat pad will start to cool down, returning to its original solid state. The time this takes is dependable on the size and model of the heat pad however the pad can be re-used again and again.
