Editing Gas sculpture (section)

==Technology==
'''Cold water fog''' nozzle technologies were developed by industry in the late 1960s for factory air particulate control and agricultural orchard freeze prevention. These high pressure systems force filtered water at {{convert|1500|to(-)|3000|psi|kPa}} through custom nozzles to atomize the water into billions of ultra-fine droplets below {{convert|10|um|in}} in size. In industrial applications this also provides cooling due to rapid evaporation.<ref>{{Cite web|url=http://www.meefog.com/technology/|title=MeeFog™ Commercial Humification, Cooling & Fogging Systems}}</ref>

Artists use this cold water fog technology to make experimental artworks that allow the viewer to safely interact and become fully immersed in the fog.

'''High temperature steam fog''' from underground steam utility lines used for commercial heat transfer, and small boiler sources, are also used by artists for atmospheric visual displays, and as a dynamic projection surfaces.

In the commercial entertainment industry these various water fog systems are used for special effects in movies, and for theme park atmospherics.

Some [[kinetic sculpture]]s contain other gaseous elements, such as the sculptures of [[Jean-Paul Riopelle]]'s ''[[La Joute]]'', which includes [[natural gas]] fire jets, a water fountain, and bronze sculptural elements.
