Hahn Brewery was established by Dr Charles “Chuck” Hahn in 1986 at an old factory site in the suburb of Camperdown in Sydney, New South Wales, Australia.
[A bubble bath], less ambiguously known as a foam bath, can be obtained by adding a product containing foaming surfactants to water and temporarily aerating it by agitation (often merely by the fall of water from a faucet). The practice is popular for personal bathing because the foam insulates the bath water, keeping it warm for longer, and (as a lime soap dispersant) prevents or reduces deposits on the bath tub at and below the water level (called “bathtub ring” and soap scum, respectively) produced by soap and hard water. It can also keep the body of the bather from being visible, preserving modesty while giving the appearance that a performer who is actually clothed is tub-bathing normally. Children find foam baths particularly amusing, so they are an inducement to get them into the bathtub.
