Sir James Dewar invented the thermos bottle in merry old England on this day in 1892 and ever since, thanks to his invention, we’ve had cold and hot liquids on demand anywhere and everywhere. In addition to keeping foods and beverages hot or cold, Sir Dewar’s thermos bottle has other uses. When there’s no running- or heated water for cleanups, savvy workers and travelers take a bottle of hot soapy water along. It makes even the most remote area seem civilized. Even Robin Leach, who created Lifestyles of the Rich and Famous (whose birthday it is today), goes nowhere without one or two or three. One is hot, one is cold and one stays bubbly. His only question: “how do it know?” Who knows? And that's the On The House tip for today.
