A fog machine, fog generator, or smoke machine is a device that emits a dense vapor that appears similar to fog or smoke. This artificial fog is most commonly used in professional entertainment applications, but smaller, more affordable fog machines are becoming common for personal use. Fog machines can also be found in use in a variety of ...
An artificial opacifying fog triggered remotely to scare off burglars. Artificial fog is man-made fog that is usually created by vaporizing a water- and glycol- or glycerine-based fluid. The fluid is injected into a heated metal block which evaporates quickly. The resulting pressure forces the vapor out of a vent.
Dry ice in water. Liquid carbon dioxide (CO 2), stored in compressed cylinders, is used in conjunction with theatrical fog machines to produce "low-lying" fog effects. When liquid CO 2 is used to chill theatrical fog, the result is a thick fog that stays within a few feet of the ground. As the fog warms, or is agitated, it rises and dissipates.
Mist and fog are aerosols. An aerosol is a suspension of fine solid particles or liquid droplets in air or another gas. [1] Aerosols can be generated from natural or human causes.The term aerosol commonly refers to the mixture of particulates in air, and not to the particulate matter alone. [2]
Liquid Solid Dispersion medium Gas No such colloids are known. Helium and xenon are known to be immiscible under certain conditions. [13] [14] Liquid aerosol Examples: fog, clouds, condensation, mist, steam, hair sprays: Solid aerosol Examples: smoke, ice cloud, atmospheric particulate matter: Liquid Foam Example: whipped cream, shaving cream
Nicknames include frozen smoke, [57] solid smoke, solid air, solid cloud, and blue smoke, owing to its translucent nature and the way light scatters in the material. The lowest-density silica nanofoam weighs 1,000 g/m 3 , [ 58 ] which is the evacuated version of the record-aerogel of 1,900 g/m 3 . [ 59 ]
The phenomenon is called fog if the visibility is 1 km (1,100 yd) or less. In the United Kingdom, the definition of fog is visibility less than 100 m (330 ft) on the surface for driving purposes, [2] while for pilots the distance is 1 km at cruising height. Otherwise, it is known as mist. A rainbow formed from the water spray at American Falls
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
