ABSTRACT:
A specially designed beverage container includes a centrally disposed conduit containing two separate reactants. The reactants are separated by a plastic membrane, and the membrane may be manually ruptured to effect a mixing of the reactants. The reactants, which comprise ammonium nitrate and distilled water, produce an endothermic reaction when mixed which in turn results in a rapid cooling of the beverage retained within the container.
