Marble Gun
A marble gun is a type of an improvised firearm or zip gun that shoots marbles, through gas pressure from the ignition of denatured alcohol. They are mainly used to shoot birds or for home defense use. Parts A marble gun has four major components: a barrel, a chamber, an ignition source, and a stock. Barrels are mostly made with PVC pipes or scrap metal tubing, sometimes even repurposed rifle barrels. Chambers are usually made from recycled PET or other similar plastic containers, albeit, resistant enough from extreme heat. A common ignition source used is the piezo ignition component found in lighters. Stocks are usually made from planks or carved wood, and there are some instances where an actual rifle stock is used. As it is an improvised weapon, it is commonly combined together using hot glue, electrical tapes, duct tapes or any combination of those adhesives. Operation Generally speaking, a marble gun is operated similarly to modern bamboo cannons, where the user spr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marble Arms
Marble Arms & Manufacturing Company of Gladstone, Michigan began in 1892 with the invention and manufacture of the Marble Universal Rifle Sight by Webster L. Marble. Retrieved 2010-12-08 Frank H. Van Cleve of Escanaba, Michigan shared patent rights on some of the early patents applied for by Webster L. Marble. Products expanded to include outdoor goods like a novel safety axe, hunting knives, match safes, compasses and the Marble Game Getter combination gun. The company grew to be a foremost manufacturer of gun sights, competing with rivals such as Lyman, Redfield, Pacific, King, and Williams gun sight companies. Still in business in Gladstone, Michigan, Marble Arms remains an important member of the firearm and shooting sports industry. List of Patents * Design for a Compass Card * Design for a Blade for a Hunting Knife * Adjustable Gun-sight * Front Sight for Fire Arms * Safety Guard for Axes * Tool Handle Fastening * Match-Box * Gaff Hook * Hunting Knife * ...

Marble Gun Ph
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; R. S. P. Beekes has suggested that a "Pre-Greek origin is probable". This stem is also the ancestor of the English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French , most other European languages (with words like "marmoreal") more closely resemble the original Ancient Greek. Physical origins Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improvised Firearm
Improvised firearms (sometimes called zip guns, pipe guns or slam guns) are firearms manufactured other than by a firearms manufacturer or a gunsmith, and are typically constructed by adapting existing materials to the purpose. They range in quality from crude weapons that are as much a danger to the user as the target to high-quality arms produced by cottage industries using salvaged and repurposed materials., Chapter 4 Improvised firearms may be used as tools by criminals and insurgents and are sometimes associated with such groups; other illicit uses include self-defense in lawless areas and hunting game in poor rural areas. Types Zip guns Zip guns are generally crude homemade firearms consisting of a barrel, breechblock and a firing mechanism. For small, low-pressure cartridges, like the common .22 caliber rimfire cartridges, even very thin-walled tubing works as a barrel, strapped to a block of wood for a handle. A rubber band powers the firing pin, which the shooter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marbles
A marble is a small spherical object often made from glass, clay, steel, plastic, or agate. They vary in size, and most commonly are about in diameter. These toys can be used for a variety of games called ''marbles'', as well being placed in marble runs or races, or created as a form of art. They are often collected, both for nostalgia and for their aesthetic colors. Sizes may range from less than to over , while some art glass marbles for display purposes are over wide. In the North of England the objects and the game are called "taws", with larger taws being called "bottle washers" after the use of a marble in Codd-neck bottles, which were often collected for play. Games History In the early twentieth century, small balls of stone from about 2500 BCE, identified by archaeologists as marbles, were found by excavation near Mohenjo-daro, in a site associated with the Indus Valley civilization. Marbles are often mentioned in Roman literature, as in Ovid's poem "Nux" (which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denatured Alcohol
Denatured alcohol (also called methylated spirits in Australia, Canada, Ireland, New Zealand, South Africa, and the United Kingdom; wood spirit; and denatured rectified spirit) is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption. It is sometimes dyed so that it can be identified visually. Pyridine and methanol, each and together, make denatured alcohol poisonous; and denatonium makes it bitter. Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used. The main additive usually is 10% methanol (methyl alcohol), hence the name ''methylated spirits''. Other common additives include isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. Denatured alcohol blends average 60 to 90% ethanol. Denaturing alcohol does not ...

PVC Pipe
Plastic pipe is a tubular section, or hollow cylinder, made of plastic. It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipes are far stiffer per unit weight than solid members. Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air, irrigation, plastic pressure pipe systems, and vacuum system applications. Types There are three basic types of plastic pipes: Solid wall pipe Extruded pipes consisting of one layer of a homogeneous matrix of thermoplastic material which is ready for use in a pipeline. Structured wall pipe Structured-wall pipes and fittings are products which have an optimized design with regard to material usage to achieve the physical ...

Piezo Ignition
Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to mechanical deformation. It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas. No external electric connection is required, though wires are sometimes used to place the sparking location away from the crystal itself. Piezo ignition systems can be operated by either a lever, push-button or built into the control knob. An electric spark An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures. ...
