...characteristic-"quiet, fizz and rush." The "quiet" pool is surrounded by a high wall with a continuous gutter that spills softly along its top, keeping the walls continuously dark and wet, adding to a public sensation of cool quiet and private peace. The "fizz" pool shoots up some 25 spray jets, producing a continual mist -"like ground fog settling among trees or over a swamp." The "rush" is a deep vortex of cascading water, studded with descending steps on which children and adults can climb, play or simply perch in the rejuvenating flow...
...were sought to incapacitate entire buildings full of people, poison food to create "confusion-anxiety-fear," cause headaches and earaches, and produce amnesia in foreign spies after interrogations or CIA agents who were about to retire. To administer the drugs surreptitiously, CIA experimenters developed pencil-like injectors and small spray guns...
...ultraviolet radiation from the sun, protecting humans and other organisms from an overdose of these solar rays. But the layer is fragile, susceptible to a number of chemicals that convert ozone back into ordinary oxygen. According to the U.N. report, the widespread use of fluorocarbons as propellants for aerosol spray deodorants and other products may have already depleted the ozone layer by 1%, and could cut it by as much as 10% by the year 2050 unless the use of fluorocarbons is reduced...
Almost simultaneously, though, a potential savior of the spray can appeared: none other than Robert Abplanalp, the Yonkers, N.Y., inventor and friend of Richard Nixon who devised the aerosol spray valve in the first place and made millions on his invention. Abplanalp showed off another invention that he claims to have worked out in six months of scrawling on notepads: a valve trade-named Aquasol that uses a mixture of water and butane gas as a propellant. Besides getting rid of the fluorocarbons, Aquasol has another advantage: the butane propellant is not in solution but floats in pressurized form...
Actually, fluorocarbons are now used in only about one-third of the spray cans sold in the U.S. But the controversy over their environmental impact has undermined sales of aerosol products of all sorts. Though many companies are looking into replacement for fluorocarbon gas, until now the only alternatives have been highly combustible gases that are unsuited to certain products, including hair sprays. Fluorocarbons, for all their drawbacks, are not combustible; neither is the butane-water mix in the Aquasol system. Anticipating the federal fluorocarbon ban, Gillette and some other manufacturers last year began switching to pump-action containers...
