Whipped-cream Charger
A whipped cream charger (colloquially called a whippet, nos or nang when used recreationally) is a steel cylinder or cartridge filled with nitrous oxide (N2O) that is used as a whipping agent in whipped cream. The narrow end of a charger has a foil covering that is broken to release the gas. This is usually done by a sharp pin inside the whipping siphon. Nitrous oxide is a popular recreational drug, and whipped cream chargers are a convenient source of the gas. Description The cylinders are about long by wide, with a volume of and capacity for most brands of of pressurized N2O. Their walls are about thick to withstand the pressure of the gas, and they are rounded at one end with a narrow tip at the other end. While refillable chargers were once available, all chargers are now non-refillable; the latter consist entirely of recyclable steel. Production In Europe, where the production and use of whip cream chargers originated, there are presently three factories invol ...

Whippet
The Whippet is a British breed of dog of sighthound type. It closely resembles the Greyhound and the smaller Italian Greyhound, and is intermediate between them in size. In the nineteenth century it was sometimes called "the poor man's racehorse". It is commonly kept as a companion dog, for competitive showing or for amateur racing, and may participate in various dog sports, including lure coursing, agility, and flyball. It has the fastest running speed within its weight and size range, and is believed to have the fastest idle-to-running acceleration of any dog. Whippets are characterized by their gentle, affectionate, and calm temperament. While typically relaxed and serene at home, they exhibit high energy and excitement when outdoors. Originally bred as hunting and racing dogs, Whippets have a strong prey drive, which may lead them to chase small animals. Whippets have a minimal-shedding coat that is easy to manage due to its short, smooth texture and lack of an unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powerlet
Crosman Corporation is an American designer, manufacturer and supplier of shooting sport products, with a long-standing presence in airgun design and a tradition of producing pellet and BB guns.

Galaxy Gas
Galaxy Gas is an American culinary brand which produces flavored whipped-cream chargers and dispensers containing nitrous oxide. It is owned by SBK International, LLC. Founded in 2021, Galaxy Gas is based in Atlanta, Georgia. Despite their dispensers being advertised for culinary use such as whipping ingredients, Galaxy Gas gained notoriety through social media in 2024 due to their products being misused as a recreational nitrous oxide inhalant to get high, with the inhalation of their canisters gaining popularity as a TikTok trend; the platform has since blocked "Galaxy Gas" as a search result. The brand's name has become genericized in reference to nitrous oxide inhalants. Galaxy Gas canisters have been sold through major retailers including Walmart and Amazon Amazon most often refers to: * Amazon River, in South America * Amazon rainforest, a rainforest covering most of the Amazon basin * Amazon (company), an American multinational technology company * Amazons, a tribe of ...

Paraffin Wax
Paraffin wax (or petroleum wax) is a soft colorless solid derived from petroleum, coal, or oil shale that consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. It is solid at room temperature and melting point, begins to melt above approximately , and its boiling point is above . Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons. Un-dyed, unscented paraffin candles are odorless and bluish-white. Paraffin wax was first created by Carl Reichenbach#Scientific contributions, Carl Reichenbach in Germany in 1830 and marked a major advancement in candlemaking technology, as it burned more cleanly and reliably than tallow candles and was cheaper to produce. In chemistry, ''paraffin'' is used synonymously with ''alkane'', indicating hydrocarbons with the general formula C''n''H2''n''+2. The name is derived from Latin ''parum'' ("very little") + ''affinis'', meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTPB
Hydroxyl-terminated polybutadiene (HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup. The properties vary because HTPB is a mixture rather than a pure compound, and it is manufactured to meet customers' specific requirements. A typical HTPB is R-45HTLO. This product consists of oligomeric units typically containing 40–50 butadiene molecules bonded together, with each end of the chain terminated with a hydroxyl Hgroup: R-45HTLO has a functionality of 2.4-2.6, which means that there is (approximately) one additional hydroxyl group located along the chain for every two oligomeric units. This provides side-to-side linkage for a stronger cured product. HTPB is usually cured by an addition reaction with di- or poly-isocyanate compounds. Uses Materials production Polyurethanes prep ...

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes and containers including bottles, cups, jars, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'' and many variations thereof. Its properties can be modified further by crosslinking or copolymerization. All forms are nontoxic as well as chemically resilient, contributing to polyethylene's popularity as a multi-use plastic. However, polyethylene's chemical resilience also makes it a long-lived and decomposition-resistant pollutant when disposed of improperly. Being a h ...

Oxidizer
An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or " accepts"/"receives" an electron from a (called the , , or ''electron donor''). In other words, an oxidizer is any substance that oxidizes another substance. The oxidation state, which describes the degree of loss of electrons, of the oxidizer decreases while that of the reductant increases; this is expressed by saying that oxidizers "undergo reduction" and "are reduced" while reducers "undergo oxidation" and "are oxidized". Common oxidizing agents are oxygen, hydrogen peroxide, and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Rocket
A hybrid-propellant rocket is a rocket with a rocket motor that uses rocket propellants in two different phases: solid rocket propellant, one solid and the other either gas or liquid rocket propellant, liquid. The hybrid rocket concept can be traced back to the early 1930s. Hybrid rockets avoid some of the disadvantages of solid rockets like the dangers of propellant handling, while also avoiding some disadvantages of Liquid-fuel rocket, liquid rockets like their mechanical complexity. Because it is difficult for the fuel and oxidizer to be mixed intimately (being different states of matter), hybrid rockets tend to fail more benignly than liquids or solids. Like liquid rocket engines, hybrid rocket motors can be shut down easily and the thrust is throttleable. The theoretical specific impulse (I_) performance of hybrids is generally higher than solid motors and lower than liquid engines. I_ as high as 400 s has been measured in a hybrid rocket using metalized fuels. Hybrid s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
N2O Cracker
N, or n, is the fourteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages, and others worldwide. Its name in English is ''en'' (pronounced ), plural ''ens''. History One of the most common hieroglyphs, snake, was used in Egyptian writing to stand for a sound like the English , because the Egyptian word for "snake" was ''djet''. It is speculated by some, such as archeologist Douglas Petrovich, that Semitic speakers working in Egypt adapted hieroglyphs to create the first alphabet. Some hold that they used the same snake symbol to represent N, with a great proponent of this theory being Alan Gardiner, because their word for "snake" may have begun with n (an example of a possible word being ''nahash''). However, this theory has become disputed. The name for the letter in the Phoenician, Hebrew, Aramaic, and Arabic alphabets is ''nun'', which means "fish" in some of these languages. This possibly conne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a colorless gas with a pungent smell that is responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of metals refining and the burning of Sour gas, sulfur-Sour crude oil, bearing fossil fuels. Sulfur dioxide is somewhat toxic to humans, although only when inhaled in relatively large quantities for a period of several minutes or more. It was known to medieval alchemy, alchemists as "volatile spirit of sulfur". Structure and bonding SO2 is a bent molecule with ''C''2v Point groups in three dimensions, symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance (chemistry), resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical-grade
A biomaterial is a substance that has been engineered to interact with biological systems for a medical purpose – either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one. The corresponding field of study, called biomaterials science or biomaterials engineering, is about fifty years old. It has experienced steady growth over its history, with many companies investing large amounts of money into the development of new products. Biomaterials science encompasses elements of medicine, biology, chemistry, tissue engineering and materials science. A biomaterial is different from a biological material, such as bone, that is produced by a biological system. However, "biomaterial" and "biological material" are often used interchangeably. Further, the word "bioterial" has been proposed as a potential alternate word for biologically-produced materials such as bone, or fungal biocomposites. Additionally, care should be exercised in defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
