A device for changing the temperature of material placed therein by a user of the device comprises an inner member having an open end for receiving and containing the material the temperature of which is to be changed, providing the device with an outer envelope, and a multi-component temperature changing composition within the outer envelope and activatable by mixing. The inner and outer member are movable relative to each other to agitate and mix and activate the composition, thus to create an endothermic reaction or an exothermic reaction. In two embodiments, the members are rigid. In one of these two embodiments, the composition is activatable by rotational movement of the members, and in the other, the composition is activatable by telescopic movement of the members. In a third embodiment, the inner and outer members are flexible and the composition is activatable by squeezing the members together.
