Party Popper
A party popper is a handheld pyrotechnic device commonly used at parties. It emits a loud popping noise by means of a small friction-actuated explosive charge that is activated by pulling a string. The explosive charge comes from a very small amount of Armstrong's mixture (a highly sensitive explosive) in the neck of the bottle-like shape. In some party poppers, the explosive charge is replaced by compressed air. In party poppers with an explosive charge, there are less than of explosive. The streamers are non-flammable for safe use. The charge or compressed air blows out some confetti or streamers and emits a popping sound. The charge is often composed of red phosphorus and strong oxidizer, such as potassium chlorate and potassium perchlorate. There are also party popper revolvers on the market, which use a Speedloader - style cartridge filled with six-party popper charges inserted into a normally colourful plastic device loosely resembling a pistol or revolver.

Pyrotechnics
Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name comes from the Greek words ''pyr'' ("fire") and ''tekhnikos'' ("made by art"). People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to an audience. In the majority of jurisdictions, special training and licensing must be obtained from local authorities to legally prepare and use proximat ...

Party
A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, recreation, or as part of a festival or other commemoration or celebration of a special occasion. A party will often feature food and beverages, and often conversation, music, dancing, or other forms of entertainment. Some parties are held in honor of a specific person, day, or event, such as a birthday party, a Super Bowl party, or a St. Patrick’s Day party. Parties of this kind are often called celebrations. A party is not necessarily a private occasion. Public parties are sometimes held in restaurants, pubs, beer gardens, nightclubs, or bars, and people attending such parties may be charged an admission fee by the host. Large parties in public streets may celebrate events such as Mardi Gras or the signing of a peace treaty ending a long war.

Armstrong's Mixture
Armstrong's mixture is a highly sensitive primary explosive. It is very friction-sensitive. Formulations vary, but one consists of 67% potassium chlorate, 27% red phosphorus, 3% sulfur, and 3% calcium carbonate. It is named for Sir William Armstrong, who invented it sometime prior to 1872 for use in explosive shells. Toys Armstrong's mixture can be used as ammunition for toy cap guns. The mixture is suspended in water with some gum arabic or similar binder and deposited in drops, each containing a few milligrams of explosive, to dry between layers of paper backing. The dots explode with some smoke when struck. Armstrong's mixture can be used in impact firecrackers known as ''cap torpedoes'', which explode on impact when the ball (made of clay or papier-mâché) is thrown or launched by slingshot. The firecrackers may include gravel with the explosive mixture to ensure detonation. Military use With the addition of a grit such as boron carbide (in a modified formulation ...

Confetti
Confetti are small pieces or streamers of paper, mylar, or metallic material which are usually thrown at celebrations, especially parades and weddings. The origins are from the Latin ''confectum'', with ''confetti'' the plural of Italian ''confetto'', small sweet. Modern paper confetti trace back to symbolic rituals of tossing grains and sweets during special occasions, traditional for numerous cultures throughout history as an ancient custom dating back to pagan times, but adapted from sweets and grains to paper through the centuries. Confetti are manufactured in multiple colors, and commercially available confetti come in many different shapes. A distinction is made between confetti and glitter; glitter is smaller than confetti (pieces usually no larger than 1mm) and is universally shiny. Most table confetti are also shiny. While they are called metallic confetti they are actually metallized PVC. The most popular shape is the star. Seasonally, Snowflake Confetti are the mos ...

Phosphorus
Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth. It has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 0.06 grams). In minerals, phosphorus generally occurs as phosphate. Elemental phosphorus was first isolated as white phosphorus in 1669. White phosphorus emits a faint glow when exposed to oxygen – hence the name, taken from Greek mythology, meaning 'light-bearer' (Latin ), referring to the " Morning Star", the planet Venus. The term '' phosphorescence'', meaning glow after illumination, derives from this property of phosphorus, although the word has since been used for a different physical process that produces a glow. The glow of phosphorus is caused by oxidation of the white (but not red) phosphorus — a process now called chem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Chlorate
Potassium chlorate is a compound containing potassium, chlorine and oxygen, with the molecular formula KClO3. In its pure form, it is a white crystalline substance. After sodium chlorate, it is the second most common chlorate in industrial use. It is a strong oxidizing agent and its most important application is in safety matches. In other applications it is mostly obsolete and has been replaced by safer alternatives in recent decades. It has been used * in fireworks, propellants and explosives, * to prepare oxygen, both in the lab and in chemical oxygen generators, * as a disinfectant, for example in medical mouthwashes, * in agriculture as an herbicide. Production On the industrial scale, potassium chlorate is produced by the salt metathesis reaction of sodium chlorate and potassium chloride: : NaClO3 + KCl → NaCl + KClO3 The reaction is driven by the low solubility of potassium chlorate in water. The equilibrium of the reaction is shifted to the right hand side by the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Perchlorate
Potassium perchlorate is the inorganic salt with the chemical formula K Cl O4. Like other perchlorates, this salt is a strong oxidizer although it usually reacts very slowly with organic substances. This, usually obtained as a colorless, crystalline solid, is a common oxidizer used in fireworks, ammunition percussion caps, explosive primers, and is used variously in propellants, flash compositions, stars, and sparklers. It has been used as a solid rocket propellant, although in that application it has mostly been replaced by the higher performance ammonium perchlorate. Production Potassium perchlorate is prepared industrially by treating an aqueous solution of sodium perchlorate with potassium chloride. This single precipitation reaction exploits the low solubility of KClO4, which is about 1/100 as much as the solubility of NaClO4 (209.6 g/100 mL at 25 °C). It can also be produced by bubbling chlorine gas through a solution of potassium chlorate and potassium hydro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolver
A revolver (also called a wheel gun) is a repeating firearm, repeating handgun that has at least one gun barrel, barrel and uses a revolving cylinder (firearms), cylinder containing multiple chamber (firearms), chambers (each holding a single cartridge (firearms), cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer (firearms), hammer partially rotates the cylinder, indexing (motion), indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in trigger (firearms)#Single-action, single-action), via internal linkage (mechanical), linkage relaying the force of the trigger-pull (as in trigger (firearms)#Double-actio ...

Speedloader
A speedloader is a device used to reduce the time and effort needed to reload a firearm. Speedloaders come in a variety of forms for reloading revolvers, or the magazines used with other types of firearms such as rifles and shotguns. Generally, speedloaders are used for loading multiple chambers of a revolver simultaneously. Such speedloaders are used for revolvers having either swing-out cylinders or top-break cylinders. Revolvers having fixed cylinders must be unloaded and loaded one chamber at a time. Speedloaders of different designs are used for loading the fixed tubular magazines of shotguns and rifles. Other speedloader designs are used to load the magazines (fixed or detachable) of semi-automatic firearms. Revolver speedloaders Circular reloaders The modern revolver circular speedloader holds a full cylinder complement of cartridges in a secure fashion, spaced in a circular configuration so as to allow the cartridges to drop simultaneously into the cylinder easily (a ...

Eye Injury
Eyes are organs of the visual system. They provide living organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons (neurones). In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods. The most simple eyes, pit eyes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
