Quizplus · Accepted Answer

The toy dunking bird operates through both evaporation and condensation processes. The head of the bird, typically covered with a fabric that absorbs water, evaporates moisture when it dips into water, cooling the head. This causes a temperature difference that condenses the internal vapor, creating a pressure difference that makes the bird tip.
