• means for inverting and detaching the base from the stem, associated with the base, for removably attaching the first end of the base to the bottom portion of the stem in a first position and for removably attaching the second end of the base to the bottom portion of the stem in a second inverted position;
• wherein the means for inverting and detaching the base includes an underside, and the stem has an external surface, the base upon being removed from the stem may be inverted exposing a socket disposed in the underside of the base, the socket having an interior surface for mating engagement with the external surface of the stem allowing insertion of the stem into the socket;
• wherein the means for inverting and detaching the base additionally includes a spike disposed on the base in opposition to the socket;
• wherein as the means for inverting and detaching the base places the base in the second inverted position, the spike may be securely penetrated into a penetrable medium to permit retaining the drinking glass in an upright position;
