Fake Snow
Fake snow is any product which simulates the appearance and texture of snow, without being made from frozen crystalline water. Fake snow has been made from many materials. In the early 1900s decorative snow was sometimes made from borax flakes and even ammonia. Before the dangers of asbestos were known, the substance was sold for Christmas tree decoration. It was also used to simulate snow in films, including ''The Wizard of Oz'' and ''Citizen Kane''. Fake snow has also been sold in spray cans which could apply the flocking to windows and indoor displays. Film and theatre When snow-like scenery is needed in live theatre, materials have included feathers, cotton, paper, breakfast cereal and potato flakes. To reduce the cleanup problem, many theatres use "snow generators" which create soapy white bubbles which disappear after a short time. A similar process has been used in film studios and backlots; one well-known example is ''It's a Wonderful Life ''It's a Wonderfu ...

White House Christmas (23972221597)
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystalline
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borax
Borax is a salt (ionic compound), a hydrated borate of sodium, with chemical formula often written . It is a colorless crystalline solid, that dissolves in water to make a basic solution. It is commonly available in powder or granular form, and has many industrial and household uses, including as a pesticide, as a metal soldering flux, as a component of glass, enamel, and pottery glazes, for tanning of skins and hides, for artificial aging of wood, as a preservative against wood fungus, and as a pharmaceutic alkalizer. In chemical laboratories, it is used as a buffering agent. The compound is often called sodium tetraborate decahydrate, but that name is not consistent with its structure. The anion is not tetraborate but tetrahydroxy tetraborate , so the more correct formula should be . Informally, the product is often called sodium borate decahydrate or just sodium borate. The terms tincal "tinkle" and tincar "tinker" refer to native borax, historically mined from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Christmas Tree
A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas. The custom was further developed in early modern Germany where German Protestant Christians brought decorated trees into their homes. It acquired popularity beyond the Lutheran areas of Germany and the Baltic governorates during the second half of the 19th century, at first among the upper classes. The tree was traditionally decorated with "roses made of colored paper, apples, wafers, tinsel, ndsweetmeats". Moravian Christians began to illuminate Christmas trees with candles, which were often replaced by Christmas lights after the advent of electrification. Today, there is a wide variety of traditional and modern ornaments, such as garlands, baubles, tinsel, and candy canes. An angel or star might be placed at the top of the tree to represent the Angel Gabriel or the Star of Bethle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerosol Spray
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist. History The concepts of aerosol probably go as far back as 1790.Bellis, MarThe History of Aerosol Spray Cans/ref> The first aerosol spray can patent was granted in Oslo in 1927 to Erik Rotheim, a Norwegian chemical engineer,Norwegian Patent No. 46613, issued on November 23, 1926 and a United States patent was granted for the invention in 1931. — Method and Means for the Atomizing or Distribution of Liquid or Semiliquid Materials, issued April 7, 1931 The patent rights were sold to a United States company for 100,000 Norwegian kroner.

Flocking (texture)
Flocking is the process of depositing many small fiber particles (called flock) onto a surface. It can also refer to the texture produced by the process, or to any material used primarily for its flocked surface. Flocking of an article can be performed for the purpose of increasing its value. It can also be performed for functional reasons including insulation, slip-or-grip friction, retention of a liquid film, and low reflectivity. Uses Flocking is used in many ways. One example is in model building, where a grassy texture may be applied to a surface to make it look more realistic. Similarly, it is used by model car builders to get a scale carpet effect. Another use is on a Christmas tree, which may be flocked with a fluffy white spray to simulate snow. Other things may be flocked to give them a texture similar to velvet, velveteen, or velour, such as t-shirts, wallpaper, gift/jewelry boxes, and upholstery. Besides the application of velvety coatings to surfaces and objects the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Instant Mashed Potatoes
Instant mashed potatoes are potatoes that have been through an industrial process of cooking, mashing and dehydrating to yield a packaged convenience food that can be reconstituted by adding hot water or milk, producing an approximation of mashed potatoes. They are available in many different flavors. Mashed potatoes can be reconstituted from potato flour, but the process is made more difficult by lumping; a key characteristic of instant mashed potatoes is that it is in the form of flakes or granules, eliminating the chunkiness. Analogous to instant mashed potatoes are instant poi made from taro and instant fufu made from yams or yam substitutes including cereals. Poha, an instant rice mush, is also much in the same spirit, as more broadly are other instant porridges, formed from flakes, granules, or pearls to avoid lumping. Brands include Smash and Idahoan Foods. Flaked instant mashed potatoes are most commonly found in stores in the United States and Canada. Granulated fo ...

It's A Wonderful Life
''It's a Wonderful Life'' is a 1946 American Christmas by medium#Films, Christmas Fantasy film, fantasy drama film produced and directed by Frank Capra, based on the short story and booklet ''The Greatest Gift'', which Philip Van Doren Stern self-published in 1943 and is in turn loosely based on the 1843 Charles Dickens novella ''A Christmas Carol''. The film stars James Stewart as George Bailey (It's a Wonderful Life), George Bailey, a man who has given up his personal dreams in order to help others in his community and whose thoughts of suicide on Christmas Eve bring about the intervention of his guardian angel, Clarence Odbody (Henry Travers). Clarence shows George all the lives he touched and what the world would be like if he did not exist. Theatrically, the film's break-even point was $6.3 million, about twice the production cost, a figure it did not come close to achieving on its initial release. Because of the film's disappointing sales, Capra was seen by some stud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
