Mercury-in-glass thermometer related to the rapid cooling (and contraction) of the glass. When Celsius decided to use his own temperature scale, he originally defined his scale "upside-down", i.e. he chose to set the boiling point of pure water at 0 °C (212 °F) and the freezing point at -100 °C (-32 °F). One year later, Frenchman Jean-Pierre Christin proposed to invert the scale with the freezing point at and the boiling point at . He named it Centigrade (100 grades). Finally, Celsius proposed a method of calibrating a thermometer: These points are adequate for approximate calibration but both vary with atmospheric pressure.
World's tallest thermometer the thermometer next to his Bun Boy restaurant. Its height -- 134 feet -- was in honor of the 134-degree record temperature set in nearby Death Valley on July 10, 1913. Soon after its construction, 70-mph winds snapped the thermometer in half, and it was rebuilt. Two years later, severe gusts made the thermometer sway so much that its light bulbs popped out. Concrete was then poured inside the steel core to reinforce the monument. Herron sold the attraction and restaurant to another local businessman, Larry Dabour, who sold it in 2005. In September 2012, the owner at that time,
