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 industrial, training, and some military applications. Typically, fog is created by vaporizing proprietary water and glycol-based or glycerin-based fluids or through the atomization of mineral oil. This fluid (often referred to colloquially as fog juice) vaporizes or atomizes inside the fog machine. Upon exiting the fog machine and mixing with cooler outside air the vapor condenses, resulting in a thick visible fog. Types Heated Heated fog machines use either an inert gas or an electric pump to propel mineral oil, propylene glycol, or glycerin and water mixture into a heat exchanger, where the solution is vaporized. The most commonly encountered form of heated fog machine is the pump machine. Very basic models of this type of machine consist...

The Mary Rose Museum is a historical museum located at Historic Dockyards in Portsmouth in the United Kingdom run by the Mary Rose Trust. Overview The museum is dedicated to the 16th-century Tudor navy warship Mary Rose as well as the historical context in which she was active. The museum opened in 1984 and displays artefacts from the ship as well as the ship itself in a dedicated ship hall. Since opening it has been visited by over a million people. History In September 2009 the ship hall was closed to allow the start of construction of a new museum that was opened at the end of May 2013. The Mary Rose Museum (2013) was designed by architects WilkinsonEyre, Perkins+Will and built by construction firm Warings. The construction was challenging because the museum was built over the ship in the dry dock, which is a listed monument. During construction of the museum, conservation of the hull continued inside a sealed "hotbox". In April 2013, the polyethylene glycol sprays were turned off and the process of controlled air drying began. In 2016 the "hotbox...

Ang etanol (Ingles:ethanol) (tinatawag ding ethyl alcohol, grain alcohol, inuming alak, o simpleng alkohol ) ay isang kompuwestong organiko na may pormulang kemikal. Ito ay isang alkohol, kasama ang formula nito na nakasulat din bilang C2H5OH, C2H6O o EtOH, kung saan ang Et ay kumakatawan sa ethyl. Ang ethanol ay isang pabagu-bago, nasusunog, walang kulay na likido na may katangiang tulad ng alak ang amoy at may masangsang na lasa. Ito ay isang sikoaktibong recreational na gamot, at ang aktibong sangkap na matatagpuan sa mga inuming alkohol . Ang ethanol ay natural na ginawa sa pamamagitan ng proseso ng pagbuburo ng mga asukal sa pamamagitan ng mga lebadura o sa pamamagitan ng mga proseso ng petrokemikal tulad ng ethylene hydration. Sa loob ng kasaysayan, ginamit ito bilang pangkalahatang pampamanhid, at may mga modernong aplikasyong medikal bilang antiseptiko, des-impektante, solvent para sa ilang gamot, at panlunas para sa pagkalason sa methanol at pagkalason sa ethylene glycol. Ito ay ginagamit bilang isang kemikal na pantunaw at sa sintesis ng mga organikong kompuwesto, at bilang...
