82-432: A J-turn is a driving maneuver in which a reversing vehicle is spun 180 degrees and continues, facing forward, without changing direction of travel. The J-turn is also called a " moonshiner's turn" (from the evasive driving tactics used by bootleggers ), a "reverse 180", a reverse flick, a "Rockford Turn", a "Rockford Spin", or simply a "Rockford" popularized by the 1970s TV show The Rockford Files . A J-turn differs from
164-577: A batch distillation basis (as opposed to a Coffey or column stills, which operate on a continuous basis). Traditionally constructed from copper , pot stills are made in a range of shapes and sizes depending on quantity and style of spirit. Geographic variations in still design exist, with certain kinds popular in parts of Appalachia , a region known for moonshine distilling. Spirits distilled in pots commonly have 40% ABV, and top out between 60 and 80% after multiple distillations. Poorly produced moonshine can be contaminated, mainly from materials used in
246-436: A bootleg turn in that the vehicle begins in reverse gear. It is often performed by stunt drivers in film and television shows. It can be performed both on dry and snowy surfaces; the latter is preferable while learning the skill. The turn is achieved by transferring the momentum of the car by reversing quickly in a straight line then turning the wheel sharply while using a brake to lock the front wheels. The driver changes into
328-490: A thermal immersion circulator , like a sous vide stick is ideal because it comes with a temperature controller. The liquid is kept heated at about 50 °C (122 °F) which slowly evaporates the ethanol to 40% ABV that condense on the inner walls of the outer vessel. The condensation that accumulates in the bottom of the vessel can then be diverted directly down through a filter containing activated carbon . The final product has approximately twice as much alcohol content as
410-601: A 1 cm sample cell. Aquatic plants , algae , and other photosynthetic organisms can live in water up to hundreds of meters deep, because sunlight can reach them. Practically no sunlight reaches the parts of the oceans below 1,000 metres (3,300 ft) of depth. The refractive index of liquid water (1.333 at 20 °C (68 °F)) is much higher than that of air (1.0), similar to those of alkanes and ethanol , but lower than those of glycerol (1.473), benzene (1.501), carbon disulfide (1.627), and common types of glass (1.4 to 1.6). The refraction index of ice (1.31)
492-427: A 5-foot-long (1.5 m) copper tube wound in spiral form. The tube first goes up to act as a simple column, and then down to cool the product. Cookware usually consists of a 30-litre (6.6 imp gal; 7.9 US gal) plastic wine bucket. The heat source is typically a thermal immersion circulator (commonly runs at 1200 W), like a sous vide stick because it is hard to find 300 W immersion heaters , and it
574-628: A forward gear as the nose comes about. The narrowest J-turn was performed in a Renault Twingo , between barriers set 3.78 metres (12.4 ft) apart. The diagonal length of the car, 3.70 metres (12.1 ft), meant stunt driver Terry Grant had a gap of 4 centimetres (1.6 in) on each side. This happened at the National Exhibition Centre in Birmingham , UK, at the PistonHeads show on 11–13 January 2008. Moonshine Moonshine

Deposition of transported sediment forms many types of sedimentary rocks , which make up the geologic record of Earth history . The water cycle (known scientifically as the hydrologic cycle) is the continuous exchange of water within the hydrosphere , between the atmosphere , soil water, surface water , groundwater, and plants. Water moves perpetually through each of these regions in
738-477: A property that is exploited by cetaceans and humans for communication and environment sensing ( sonar ). Metallic elements which are more electropositive than hydrogen, particularly the alkali metals and alkaline earth metals such as lithium , sodium , calcium , potassium and cesium displace hydrogen from water, forming hydroxides and releasing hydrogen. At high temperatures, carbon reacts with steam to form carbon monoxide and hydrogen. Hydrology
820-477: A registered distillery is illegal in many countries. Currently in the United States, there are four states that allow the production of moonshine for personal consumption ( Alaska , Arizona , Massachusetts , and Missouri ). Additionally, North Dakota law permits the production of moonshine for personal consumption up to the federally legal amount—which is zero gallons; entailing that production of any amount
902-705: A result of excise laws and became meaningful in the United States only after a tax passed after the Revolutionary War outlawing non-registered stills with the Tariff of 1791 , or the Excise Whiskey Tax of 1791. This tax led to the Whiskey Rebellion lasting between 1791 and 1794, where the tax went unpaid by the rebels and was met with violent protest. This tax lasted until 1802, when it was repealed. Another tax

Radiators used as condensers may contain lead at the plumbing joints, and their use has resulted in blindness or lead poisoning from tainted liquor. This was a deadly hazard during the Prohibition -era United States. Consumption of lead-tainted moonshine is a serious risk factor for saturnine gout , a very painful but treatable medical condition that damages
1066-400: A still. To cut costs, stainless steel vessels are often replaced with plastic stills , vessels made from polypropylene that can withstand relatively high heat. The preferred heat source for plastic stills or spiral stills is sous vide sticks; these control temperature, time, and circulation, and are therefore preferred over immersion heaters . Multiple units can be used to increase
1148-440: A structure of rigid oxygen atoms in which hydrogen atoms flowed freely. When sandwiched between layers of graphene , ice forms a square lattice. The details of the chemical nature of liquid water are not well understood; some theories suggest that its unusual behavior is due to the existence of two liquid states. Pure water is usually described as tasteless and odorless, although humans have specific sensors that can feel
1230-486: A study of farmers in Cocke County, Tennessee , observes: "One could transport much more value in corn if it was first converted to whiskey. One horse could haul ten times more value on its back in whiskey than in corn." Moonshiners such as Maggie Bailey of Harlan County, Kentucky , Amos Owens of Rutherford County, North Carolina , and Marvin "Popcorn" Sutton of Maggie Valley, North Carolina , became legendary. Once
1312-412: A swimming pool when the light source is sunlight reflected from the pool's white tiles. In nature, the color may also be modified from blue to green due to the presence of suspended solids or algae. In industry, near-infrared spectroscopy is used with aqueous solutions as the greater intensity of the lower overtones of water means that glass cuvettes with short path-length may be employed. To observe
1394-411: A tainted distillate burns with a yellow flame. Practitioners of this simple test also held that if a radiator coil had been used as a condenser, then there would be lead in the distillate, which would give a reddish flame. This led to the mnemonic , "Lead burns red and makes you dead," or simply, "Red means dead." Manufacturing of spirits through distilling, fractional crystallization , etc. outside

In Earth's mantle, it acts as a solvent during mineral formation, dissolution and deposition. The normal form of ice on the surface of Earth is ice I h , a phase that forms crystals with hexagonal symmetry . Another with cubic crystalline symmetry , ice I c , can occur in
1558-403: Is high-proof liquor , traditionally made or distributed illegally . The name was derived from a tradition of distilling the alcohol at night to avoid detection. In the first decades of the 21st century, commercial distilleries have adopted the term for its outlaw cachet and have begun producing their own legal "moonshine", including many novelty flavored varieties, that are said to continue
1640-489: Is visibly blue due to absorption of light in the region c. 600–800 nm. The color can be easily observed in a glass of tap-water placed against a pure white background, in daylight. The principal absorption bands responsible for the color are overtones of the O–H stretching vibrations . The apparent intensity of the color increases with the depth of the water column, following Beer's law . This also applies, for example, with
1722-439: Is 917 kg/m (57.25 lb/cu ft), an expansion of 9%. This expansion can exert enormous pressure, bursting pipes and cracking rocks. In a lake or ocean, water at 4 °C (39 °F) sinks to the bottom, and ice forms on the surface, floating on the liquid water. This ice insulates the water below, preventing it from freezing solid. Without this protection, most aquatic organisms residing in lakes would perish during

Plastic stills are common because they are cheap and easy to manufacture. The principle is that a smaller amount of liquid is placed in an open smaller vessel inside a larger one that is closed. A cheap 100 W immersion heater is typically used as heat source, but
1968-428: Is greater than the repulsion between the hydrogen atoms. The O–H bond length is about 0.096 nm. Other substances have a tetrahedral molecular structure, for example methane ( CH 4 ) and hydrogen sulfide ( H 2 S ). However, oxygen is more electronegative than most other elements, so the oxygen atom has a negative partial charge while the hydrogen atoms are partially positively charged. Along with
2050-561: Is illegal. Popular offerings for the Maya deity and folk saint Maximón include money, tobacco, and moonshine. Moonshine is by tradition usually a clear, unaged whiskey, once made with barley mash in Scotland and Ireland or maize corn mash in the United States, though plain sugar became just as common in illicit liquor during the last century. The word originated in the British Isles as

Water in the mantle is responsible for the melt that produces volcanoes at subduction zones . On the surface of the Earth, water is important in both chemical and physical weathering processes. Water, and to a lesser but still significant extent, ice, are also responsible for

Any water on Earth during the latter part of its accretion would have been disrupted by
2296-498: Is known as the critical point . At higher temperatures and pressures the liquid and vapor phases form a continuous phase called a supercritical fluid . It can be gradually compressed or expanded between gas-like and liquid-like densities; its properties (which are quite different from those of ambient water) are sensitive to density. For example, for suitable pressures and temperatures it can mix freely with nonpolar compounds , including most organic compounds . This makes it useful in
2378-413: Is lower than that of liquid water. In a water molecule, the hydrogen atoms form a 104.5° angle with the oxygen atom. The hydrogen atoms are close to two corners of a tetrahedron centered on the oxygen. At the other two corners are lone pairs of valence electrons that do not participate in the bonding. In a perfect tetrahedron, the atoms would form a 109.5° angle, but the repulsion between the lone pairs
2460-422: Is poor at dissolving nonpolar substances. This allows it to be the " solvent of life": indeed, water as found in nature almost always includes various dissolved substances, and special steps are required to obtain chemically pure water . Water is the only common substance to exist as a solid , liquid, and gas in normal terrestrial conditions. Along with oxidane , water is one of the two official names for
2542-468: Is risky to disassemble the immersion heater from an electric water boiler because it may cause electrical injury . The spiral burner is popular because, despite its simple construction and low manufacturing cost, it can provide 95% ABV . A pot still is a type of distillation apparatus or still used to distill flavored liquors such as whisky or cognac , but not rectified spirit because they are poor at separating congeners . Pot stills operate on

The rock vapor would have condensed within two thousand years, leaving behind hot volatiles which probably resulted in a majority carbon dioxide atmosphere with hydrogen and water vapor . Afterward, liquid water oceans may have existed despite

In most substances, the volume increases when melting occurs, so the melting temperature increases with pressure. However, because ice is less dense than water, the melting temperature decreases. In glaciers, pressure melting can occur under sufficiently thick volumes of ice, resulting in subglacial lakes . The Clausius-Clapeyron relation also applies to

Alcohol concentrations at higher strengths (the GHS identifies concentrations above 24% ABV as dangerous ) are flammable and therefore dangerous to handle. This is especially true during the distilling process, when vaporized alcohol may accumulate in the air to dangerous concentrations if adequate ventilation is not provided. Contaminated moonshine can occur if proper materials and techniques are not used. The prolonged consumption of impure moonshine may cause renal disease , primarily from increased lead content. Analysis of Georgia moonshine samples revealed potentially toxic levels of copper, zinc, lead, and arsenic. A review of twelve arsenic poisoning cases found contaminated moonshine responsible for about half, suggesting it may be
3362-456: The "foreshot" – the first 50–150 millilitres (1.8–5.3 imp fl oz; 1.7–5.1 US fl oz) of alcohol that drip from the condenser. Because methanol vaporizes at a lower temperature than ethanol, it is commonly believed that the foreshot contains most of the methanol, if any, from the mash. However, research shows that methanol is present until the very end of the distillation run. Despite this, distillers will usually collect

Water is a good polar solvent , dissolving many salts and hydrophilic organic molecules such as sugars and simple alcohols such as ethanol . Water also dissolves many gases, such as oxygen and carbon dioxide —the latter giving the fizz of carbonated beverages, sparkling wines and beers. In addition, many substances in living organisms, such as proteins , DNA and polysaccharides , are dissolved in water. The interactions between water and
3772-520: The boiling point, but with the liquid/gas transition the vapor phase has a much lower density than the liquid phase, so the boiling point increases with pressure. Water can remain in a liquid state at high temperatures in the deep ocean or underground. For example, temperatures exceed 205 °C (401 °F) in Old Faithful , a geyser in Yellowstone National Park . In hydrothermal vents ,

The addition or removal of heat can cause phase transitions : freezing (water to ice), melting (ice to water), vaporization (water to vapor), condensation (vapor to water), sublimation (ice to vapor) and deposition (vapor to ice). Water differs from most liquids in that it becomes less dense as it freezes. In 1 atm pressure, it reaches its maximum density of 999.972 kg/m (62.4262 lb/cu ft) at 3.98 °C (39.16 °F), or almost 1,000 kg/m (62.43 lb/cu ft) at almost 4 °C (39 °F). The density of ice

Hydrogen bonds are about ten times as strong as the Van der Waals force that attracts molecules to each other in most liquids. This is the reason why the melting and boiling points of water are much higher than those of other analogous compounds like hydrogen sulfide. They also explain its exceptionally high specific heat capacity (about 4.2 J /(g·K)), heat of fusion (about 333 J/g), heat of vaporization ( 2257 J/g ), and thermal conductivity (between 0.561 and 0.679 W/(m·K)).

Large quantities of water, ice, and steam are used for cooling and heating in industry and homes. Water is an excellent solvent for a wide variety of substances, both mineral and organic; as such, it is widely used in industrial processes and in cooking and washing. Water, ice, and snow are also central to many sports and other forms of entertainment, such as swimming , pleasure boating, boat racing , surfing , sport fishing , diving , ice skating , snowboarding , and skiing .

5986-488: The surface of a planet is called the hydrosphere . Earth's approximate water volume (the total water supply of the world) is 1.386 billion cubic kilometres (333 million cubic miles). Liquid water is found in bodies of water , such as an ocean, sea, lake, river, stream, canal , pond, or puddle . The majority of water on Earth is seawater . Water is also present in the atmosphere in solid, liquid, and vapor states. It also exists as groundwater in aquifers . Water
6068-534: The surface temperature of 230 °C (446 °F) due to the increased atmospheric pressure of the CO 2 atmosphere. As the cooling continued, most CO 2 was removed from the atmosphere by subduction and dissolution in ocean water, but levels oscillated wildly as new surface and mantle cycles appeared. Geological evidence also helps constrain the time frame for liquid water existing on Earth. A sample of pillow basalt (a type of rock formed during an underwater eruption)
6150-403: The temperature can exceed 400 °C (752 °F). At sea level , the boiling point of water is 100 °C (212 °F). As atmospheric pressure decreases with altitude, the boiling point decreases by 1 °C every 274 meters. High-altitude cooking takes longer than sea-level cooking. For example, at 1,524 metres (5,000 ft), cooking time must be increased by a fourth to achieve
6232-583: The term "moonshine" being used to refer to illicit alcohol dates to the 1785 edition of Grose's Dictionary of the Vulgar Tongue , which was published in England. Prior to that, "moonshine" referred to anything "illusory" or to literally the light of the moon. The U.S. Government considers the word a "fanciful term" and does not regulate its use on the labels of commercial products, as such, legal moonshines may be any type of spirit, which must be indicated elsewhere on
6314-419: The tradition by using a similar method and/or locale of production. In 2013, moonshine accounted for about one-third of global alcohol consumption. Different languages and countries have their own terms for moonshine (see Moonshine by country ). The ethanol may be concentrated in fermented beverages by means of freezing. For example, the name applejack derives from the traditional method of producing
6396-458: The upper atmosphere. As the pressure increases, ice forms other crystal structures . As of 2024, twenty have been experimentally confirmed and several more are predicted theoretically. The eighteenth form of ice, ice XVIII , a face-centred-cubic, superionic ice phase, was discovered when a droplet of water was subject to a shock wave that raised the water's pressure to millions of atmospheres and its temperature to thousands of degrees, resulting in
6478-481: The wattage. Also, sous vide sticks, commonly sold in 1200 W and generally temperature regulated up to 90 °C (194 °F) (ethanol boils at 78 °C (172 °F)), will evaporate the ethanol faster than an immersion heater , commonly sold in 300 W. Electrical injury may occur if immersion heaters are modified, as if a 35 °C (95 °F) thermostat is removed from an aquarium heater (because doing so may break its waterproofing ), or if an immersion heater
6560-441: The winter. Water is a diamagnetic material. Though interaction is weak, with superconducting magnets it can attain a notable interaction. At a pressure of one atmosphere (atm), ice melts or water freezes (solidifies) at 0 °C (32 °F) and water boils or vapor condenses at 100 °C (212 °F). However, even below the boiling point, water can change to vapor at its surface by evaporation (vaporization throughout
6642-641: Was introduced with the Revenue Act of 1861 and Revenue Act of 1862 that heavily taxed the production of spirits leading to an increase in illegal distilling and in turn, increased action from revenue agents that enforced the taxes. Illegal distilling accelerated during the Prohibition era (1920–1933), which mandated a total ban on alcohol production under the Eighteenth Amendment of the Constitution . Since
6724-784: Was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago. In the Nuvvuagittuq Greenstone Belt , Quebec, Canada, rocks dated at 3.8 billion years old by one study and 4.28 billion years old by another show evidence of the presence of water at these ages. If oceans existed earlier than this, any geological evidence has yet to be discovered (which may be because such potential evidence has been destroyed by geological processes like crustal recycling ). More recently, in August 2020, researchers reported that sufficient water to fill
