Zusammenfassung:	A three-compartment, instant hot or cold, reusable cold pack for transferring heat to or from an object. A first compartment contains a predetermined amount of a solvent comprised primarily of water. A second compartment contains a predetermined amount of a solute capable of essentially completely dissolving in the solvent. A third compartment contains a gelling agent capable of gelling with the solvent and solute solution and producing a gel that is relatively soft and moldable when frozen.
