Short Black Haired Girl Having A Bubble Bath With A Foam

Machine-aerated baths originated in the early 20th century for therapeutic use, becoming more widely used with the introduction of the jacuzzi. Trends merged when the hot tub, which originally had still water, with its increasing popularity became more commonly a communal whirlpool bath. By the late 20th century jetted bathtubs had become popular for home installation.
It is possible to produce baths with bubbles simultaneously in and on top of the water (as in a poured beer), but the combination has not been popular. Mechanical aeration of a foam bath may produce much more foam than is sought—the Internet is replete with first hand accounts and sometimes photographs of such experiences—and many mechanically aerated baths are hot tubs which are shared and not drained between uses and so are desired to be kept free of non-maintenance materials. Mechanically aerated baths for tissue debridement of burn victims typically have added anti-foaming agents to counteract the film-forming properties that some medicinal additives have as a side effect, but the anti-foam is sometimes omitted or reduced for children to give them more of a pleasant distraction during debridement. Bath fizzies that also foam tend to produce disappointingly little foam when allowed to do so from their own fizz, and aeration of the water loses the gas from the fizz.
