HEEBIE JEEBIES FITZROY STORM GLASS

The 28 cm (11 inch) Fitzroy Storm Glass is a sealed glass container filled with a liquid which responds to changes in the weather, allowing the observer to forecast the possibility of storms, snow, wind, rain or clear skies. Its visually stunning changes make the storm glass functional and attractive ornament. The Fitzroy Storm Glass is made of high quality glass with encapsulated liquid. This specific mixture was developed by Admiral Robert Fitzroy and used on his voyage with Charles Darwin on the HMS Beagle. During the historic voyage, Fitzroy carefully documented how the storm glass would predict the weather. In 1859, violent storms struck the British Isles. In response, the British Crown distributed storm glasses, then known as “Fitzroy’s storm barometers,” to many small fishing communities around the British Isles that were to be consulted by ships at port before setting sail.

• Liquid sealed in 11-inch glass container responds to changes in the weather
• Works on the principle that temperature and pressure affect solubility
• Liquid is affected in part by barometric pressure and changes in temperature
