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 ...
"Low-lying" fog effects can be created by combining a fog machine with another device designed specifically for this purpose. As the fog exits the fog machine it is chilled, either by passing through a device containing a fan and ice, or by passing through a device containing a fan and compressor similar to an air conditioner. The result is a ...
Scientists find that one atom of it dropped into a barrel of water becomes one barrel of ice cream; a different flavor of ice cream each time. To avoid evaporation, bombastium must be kept frozen. [27] When this totally new element is discovered Scrooge tries to secure the entire supply – a ball of "Bombastium" about the size of a large turnip.
Falling diamond dust (Inari, Finland) Diamond dust is similar to fog in that it is a cloud based at the surface; however, it differs from fog in two main ways. Generally fog refers to a cloud composed of liquid water (the term ice fog usually refers to a fog that formed as liquid water and then froze, and frequently seems to occur in valleys with airborne pollution such as Fairbanks, Alaska ...
Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. [1] [2] Fog can be considered a type of low-lying cloud usually resembling stratus and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog affects many human activities, such ...
Haze typically has a substantially longer persistence ("hang time") than conventional theatrical fog. 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.
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] Examples of natural aerosols are fog, mist or dust.
Unlike most artificial fog machines, in which fog rises like smoke, fog from dry ice hovers near the ground. [14] Dry ice is useful in theatre productions that require dense fog effects. [22] The fog originates from the bulk water into which the dry ice is placed, and not from atmospheric water vapor (as is commonly assumed). [23]
