A thin-walled cup is formed of a single piece of polymeric material having a uniform thickness throughout the extent of the single piece of polymeric material. The cup has an outer chamber which extends around an inner chamber. The outer chamber holds a first liquid and the inner chamber holds a second liquid. The liquid in the inner chamber is mixed with the liquid in the outer chamber during drinking from the cup. The cup is made by a thermoforming process. The thermoforming process may include embossing indicia on the cup.
