Dry Ice Bomb
A dry ice bomb is a simple explosive device. While their simplicity, ease of construction, high bursting pressure and loud noise make them appealing for recreational purposes, they can be unpredictable and dangerous. These bombs have led to many injuries and are illegal in many jurisdictions. Overview Dry ice bombs are commonly made from a container such as a plastic bottle, water and dry ice. The bottle is partly filled with water. Chunks of dry ice are added and the container is closed tightly. As the solid carbon dioxide warms, it sublimates to gas and the pressure in the bottle increases. Bombs typically rupture within 30 seconds to half an hour, dependent largely on the temperature of the air outside the bottle. A dry ice bomb may develop frost on its exterior prior to explosion. After explosion, it appears to have shattered, with the overall shape of the device intact. Dangers Dry ice bombs may induce serious risks: * Explosion can occur within seconds, injuring the han ...

Liquid Nitrogen Cocktail
A liquid nitrogen cocktail is any mixed drink whose preparation involves the use of liquid nitrogen. Popularized as a novelty because of the smoky, bubbling "cauldron effect" it produces, liquid nitrogen is controversial as a cocktail ingredient because it boils at and its consumption is thus potentially lethal. However, it is not a regulated substance in most countries and there is little control of its use. History The culinary use of liquid nitrogen is mentioned in an 1890 recipe book titled ''Fancy Ices'' by Agnes Marshall, but has been employed in more recent times by restaurants in the preparation of frozen desserts, such as ice cream, which can be created within moments at the table because of the speed at which it cools food. Similarly, liquid nitrogen has become popular in the preparation of cocktails because it can be used to quickly chill glasses or freeze ingredients. It is also added to drinks to create a smoky effect, which is created by the cold nitrogen vapour (liq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Phase Transition
Rapid phase transition or RPT is a phenomenon realized in liquefied natural gas (LNG) incidents in which LNG vaporizes violently upon coming in contact with water causing what is known as a ''physical explosion'' or ''cold explosion''. During such explosions there is no combustion but rather a huge amount of energy is transferred in the form of heat from the room-temperature water to the LNG at a temperature difference of about . LNG Properties Liquefied natural gas or LNG is a natural gas that gets liquefied at atmospheric pressure and −161.5 °C. It is odorless, tasteless, colorless, and not poisonous but causes asphyxia. It can cause frostbite due to its cryogenic temperature. If this extremely cold LNG is mixed with water(e.g. sea water, which has an average temperature of 15 °C), heat energy is transferred from the water to the LNG, rapidly vaporizing it from its liquefied state back into its original gaseous state. This results in an explosion because the volu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorine Bomb
A chlorine bomb is a small explosive device which uses the pressure of chemically produced chlorine gas or other chlorine-containing gases such as hydrogen chloride to produce an explosion. It is made with an airtight container part-filled with different types of chlorine tablet and other reagents. The reaction produces an expansive increase in pressure, eventually rupturing the container. Usually, such a device is not made on a large scale, often being manufactured from common house objects. Such a device is a more toxic and acidic alternative to a dry ice bomb, but likewise typically made by young people for amusement and recreational use rather than with any intent to harm. However, exposure to chlorinous gases and the reactive substances involved can cause respiratory problems from inhalation and also cause injury to other mucous membranes, similar to tear gas. Most injuries relating to these devices involve bruised hands, blinding and other eye injuries. Contrary to the opini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diet Coke And Mentos Eruption
A Diet Coke and Mentos eruption (also known as a soda geyser) is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage (this will work on any drink that is carbonated), which creates an eruption that pushes most of the liquid up and out of the bottle. Lee Marek and "Marek's Kid Scientists" were the first to publicly demonstrate the experiment on the ''Late Show with David Letterman'' in 1999. Steve Spangler's televised demonstration of the eruption in 2005 became popular on YouTube, launching a chain of several other Diet Coke and Mentos experiment viral videos. Experiments carried out at altitudes ranging from below sea level in Death Valley to the summit of Pikes Peak have demonstrated that the reaction works better at higher elevations. History In the 1910s, Wint-O-Green Life Savers were used to create soda geysers. The tubes of candies were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Endangerment
Endangerment is a type of crime involving conduct that is wrongful and reckless or wanton, and likely to produce death or grievous bodily harm to another person. There are several kinds of endangerment, each of which is a criminal act that can be prosecuted in a court. In some U.S. states, such as Florida, substantially similar language is used for the crime of culpable negligence. The offense is intended to prohibit and therefore deter reckless or wanton (of a cruel or violent action, deliberate and unprovoked conduct) that wrongfully creates a substantial risk of death or serious injury to others. Various laws specify several types of endangerment: *Child endangerment and animal endangerment: placing a child or animal in a potentially harmful situation, either through negligence or misconduct. *Reckless endangerment: A person commits the crime of reckless endangerment or wanton endangerment if the person recklessly engages in conduct which creates substantial jeopardy of sev ...

The Press
''The Press'' is a daily newspaper published in Christchurch, New Zealand owned by media business Stuff Ltd. First published in 1861, the newspaper is the largest circulating daily in the South Island and publishes Monday to Saturday. One community newspaper—''Northern Outlook''- is also published by ''The Press'' and is free. The newspaper has won the title of New Zealand Newspaper of the Year (in its circulation category) three times: in 2006, 2007 and 2012. It has also won the overall Newspaper of the Year title twice: in 2006 and 2007. History James FitzGerald came to Lyttelton on the ''Charlotte Jane'' in December 1850, and was from January 1851 the first editor of the ''Lyttelton Times'', Canterbury's first newspaper. From 1853, he focussed on politics and withdrew from the ''Lyttelton Times''. After several years in England, he returned to Canterbury concerned about the proposed capital works programme of the provincial government, with his chief concern the pro ...

Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives". Explosives may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esophagus
The esophagus (American English) or oesophagus (British English; both ), non-technically known also as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous epithel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frost
Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
