Rubber Duck
The modern rubber duck demonstrates exceptional longevity under standard operating conditions. Constructed from PVC or vinyl polymers, a quality specimen maintains structural integrity for decades when stored appropriately between uses.
Laboratory testing indicates that rubber ducks can withstand continuous water immersion without degradation for periods exceeding ten years. The material resists UV damage, thermal cycling between room temperature and bath-water temperatures of 40-45 degrees Celsius, and repeated compression from enthusiastic squeezing. Archaeological evidence from landfill excavations confirms rubber ducks remaining identifiable after fifty years of burial, though this durability presents its own environmental considerations.
The primary failure mode involves the gradual deterioration of the internal squeaking mechanism, typically occurring after several thousand activation cycles. Even post-squeak-failure, the duck remains fully functional for its primary buoyancy duties.
Tea
A cup of tea maintains optimal quality for approximately fifteen to thirty minutes following preparation. After this window, thermal degradation renders the beverage lukewarm, and oxidation compounds alter the flavor profile unfavorably.
Extended observation reveals that tea left unattended for several hours develops surface film formations and bitter compounds that compromise palatability entirely. At the twenty-four hour mark, microbiological activity may commence, rendering the tea not merely unpleasant but potentially hazardous. The liquid phase itself will persist indefinitely through evaporation, eventually leaving only residual tannin deposits on the vessel interior.
From a durability standpoint, tea exists in a state of continuous degradation from the moment of preparation. It is, by any reasonable measure, a consumable in active decline.
VERDICT
The durability differential between these two entities spans multiple orders of magnitude. Where the rubber duck operates on timescales measured in decades, tea functions on timescales measured in minutes.
A single rubber duck purchased in 1985 may still provide satisfactory service in 2024. A cup of tea brewed at 9:00 AM becomes objectionable by 9:45 AM. This temporal asymmetry proves insurmountable by any analytical framework. The rubber duck achieves victory in this category by a margin that renders percentage comparisons meaningless.
