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.
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]
So-called 'smoke machines' or 'hazers' vaporize a mixture of propylene glycol and water to create the illusion of smoke. While many of these machines use a propylene glycol-based fluid, some use oil. Those which use propylene glycol do so in a process that is identical to how electronic cigarettes work; utilizing a heating element to produce a ...
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
At least seven people were killed Monday after a “superfog” of smoke from marsh fires and dense morning fog caused a series of wrecks on Interstate 55 near New Orleans that left a long stretch ...
While conventional fog will hang in the air for several minutes, a haze effect filling the same volume of space can last upwards of an hour to several hours or more, depending on the size of the venue and the amount of ventilation. The fluid used in haze machines to generate the effects are either oil or water-based.
