Brief introduction of air blowing bottle
A storm flask is a device used to indicate the weather. The main body is a sealed glass bottle filled with solution. Users can predict the weather by looking at the solution in the bottle. The solution in the bottle is a mixed solution of several substances, usually including distilled water, ethanol, potassium nitrate, ammonium chloride and camphor. This unique recipe was invented by robert fitzroy, commander of the Beagle, while accompanying Charles Darwin on his voyage. Admiral robert fitzroy is at 1834? From 65438 to 0836, he accompanied Charles Darwin's expedition. In addition to his naval work, fitzroy was a pioneer in meteorology. Some instruments used by Darwin on the Beagle, including the precise timer and barometer, were also used by fitzroy to indicate the weather. In this expedition, Beaufort scale, as the wind observation unit, also set a precedent.
Modern research has confirmed that temperature is the most important factor affecting the crystal form in bottles; The corresponding relationship with the weather is almost randomly distributed and has no predictive value. Although it can't be used to forecast the weather, the gas cylinder can still be used as a beautiful ornament, because its crystal changes with the change of external temperature. It can also be used as an interesting science textbook to learn the configuration and crystallization behavior of solutions.
