The History of the Soda Fountain

The History of the Soda Fountain In the early 20th century and until the 1960s, it was common for small-town residents and big-city dwellers to enjoy carbonated beverages at local soda fountains and ice cream saloons. Often housed together with apothecaries, the ornate, baroque soda fountain counter served as a meeting place for people of all ages and became especially popular as a legal place to gather during Prohibition. By the 1920s, just about every apothecary had a soda fountain. Soda Fountain Manufacturers Some soda fountains back in the day were the Transcendent, which had miniature Greek statues on top of them and four spigots and a cupola topped with stars. Then there was the Puffer Commonwealth, which had more spigots and was more statuesque. The four most successful manufacturers of soda fountains - Tuft’s Arctic Soda Fountain, A.D. Puffer and Sons of Boston, John Matthews and Charles Lippincott - created  a monopoly of the soda fountain manufacturing business  by combining to form the American Soda Fountain Company in 1891. A Little History The term soda water was first coined in 1798, and in  1810 the first U.S. patent was issued for the mass manufacture of imitation mineral waters to inventors Simons and Rundell of Charleston, South Carolina. The soda fountain patent was first granted to Samuel Fahnestock in 1819. He had invented a  barrel-shaped with a pump and spigot to dispense  carbonated water, and the device was meant to be kept under a counter or hidden. In 1832 John Matthews  invented a design that would make artificially carbonating water more cost-effective. His machine - a metal-lined chamber where sulphuric acid and calcium carbonate were mixed to make carbon dioxide - artificially carbonated waters at a quantity that could be sold to drugstores or street vendors. Gustavus D.  Dows invented and operated the first marble soda fountain and ice shaver, which he patented in 1863. It was housed in a miniature cottage and was functional, and made of eye-pleasing white Italian marble, onyx and glistening brass with large mirrors. The New York Times wrote that Mr. Dows was the  first to create a fountain that looked like a Doric temple. James Tufts patented a soda fountain in 1883  that he called the Arctic Soda Apparatus. Tufts went on to become a huge soda fountain manufacturer and sold more soda fountains than all of his competitors combined. In 1903 a revolution in soda fountain design took place with the front-service fountain patented by Haeusser Heisinger. Soda Fountains Today The popularity of soda fountains collapsed in the 1970s  with the introduction of fast foods, commercial ice cream, bottled  soft drinks, and restaurants. Today, the  soda fountain is nothing other than a small,  self-serve soft drink dispenser. Old-fashioned soda fountain parlors within apothecaries - where druggists would serve syrup and chilled, carbonated soda water - are most likely found in museums nowadays.

What Tear Gas Is and How It Works

What Tear Gas Is and How It Works Tear gas, or lachrymatory agent, refers to any of a number of chemical compounds that cause tears and pain in the eyes and sometimes temporary blindness. Tear gas can be used for self-defense, but it is more commonly used as a riot control agent and as a chemical weapon. How Tear Gas Works Tear gas irritates the mucous membranes of the eyes, nose, mouth, and lungs. The irritation may be caused by a chemical reaction with the sulfhydryl group of enzymes, though other mechanisms also occur. The results of exposure are coughing, sneezing, and tearing. Tear gas generally is non-lethal, but some agents are toxic. Examples of Tear Gas Actually, tear gas agents arent usually gases. Most compounds used as lachrymatory agents are solids at room temperature. They are suspended in solution and sprayed as aerosols or in grenades. There are different types of compounds that may be used as tear gas, but they often share the structural element ZC-C-X, where Z denotes carbon or oxygen and X is bromide or chloride. CS (chlorobenzylidenemalononitrile)CRCN (chloroacetophenone) which may be sold as Macebromoacetonephenacyl bromidexylyl bromidepepper spray (derived from chili peppers and most commonly dissolved in a vegetable oil) Pepper spray is a little different from the other types of tear gas. It is an inflammatory agent that causes inflammation and burning of the eyes, nose, and mouth. While it is more debilitating than a lachrymatory agent, it is harder to deliver, so it is used more for personal protection against a single individual or animal than for crowd control.
