Knife Juggling
Knife juggling is a variant of toss juggling using blunt knives as props which are thrown and caught. Although knives are sometimes juggled recreationally, it is generally a performance art. Knife juggling is typically seen performed by street entertainers as part of a routine, or at art or historical festivals. The knives are thrown with vertical spin, lending them stability in the air, and are typically allowed to rotate once or twice before being caught. Knife juggling can be performed with any number of objects, but the vast majority of performers use three knives. Patterns used are usually basic and consist solely of a cascade, and sometimes involve simple juggling tricks such as an under the leg throw. This is due to the unwieldy nature and increased weight of knives and the increased level of danger when compared to such props as juggling clubs. Knives used Juggling is rarely performed with sharp knives, because there is little point in increasing the risk to performer ...

Chainsaw
A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and harvesting of firewood. Chainsaws with specially designed bar-and-chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete during construction developments. Chainsaws are sometimes used for cutting ice; for example, ice sculpture and winter swimming in Finland. History In surgery The origin of chain saws in surgery is debated. A "flexible saw", consisting of a fine serrated link chain held between two wooden handles, was pioneered in the late 18th century (c. 1783–1785) by two Scottish doctors, John Aitken and James Jeffray, for symphysiotomy and excision of diseased bone, respectively. It was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juggling Props
A skill toy is an object or theatrical prop used for dexterity play or an object manipulation performance. A skill toy can be any static or inanimate object with which a person dances, manipulates, spins, tosses, or simply plays. Most skill toys are played alone, although some can be played with multiple people (such as footbag, juggling, and jump rope). Examples Common examples of skill toys include: * Bamboo-copter *Balance board (Rola bola, Rocker, Rocker-roller, Wobble, Sphere-and-ring, Spring board, Above Water and Under Water balance boards)) **Bilibo **Seesaw **Simply Fit Board **Teeterboard *** Neolttwigi * Ball-in-a-maze puzzle ** Labyrinth (marble game) ** Perplexus ** Rubik's 360 * Balloon modelling (Balloon twisting) * Baton * Bicycle and related forms ** Balance bicycle *** Kickbike ** Jyrobike ** Quadracycle ** Tricycle *** Big wheel ** Unicycle * Bolas **Alaska yo-yo ** Astrojax **Clackers **Meteor **Monkey Knuckles ** Oxbow hammer (Puppy hammer) ** Poi * Begleri ...

Thom Wall
Thom Wall (born February 9, 1987) is a juggler and variety entertainer from Saint Louis, Missouri, USA. NPR has called him "one of the world's most notable jugglers." Wall is known for his avant-garde performance style, cultivated through training at the New England Center for Circus Arts, lessons with mime Karen Montanaro, and training with long-time friend Curtis Carlyle. In 2009, Wall competed at the World Juggling Federation's "Winter Blitz" event. No judge had seen any of his creative five-ball tricks performed before, so his routine was deemed unscoreable. In 2017, the Smithsonian Institution called Thom an "elite practitioner of the craft of juggling." Thom is one of the last gentleman jugglers performing in the world today - a performance style where relatable objects are manipulated in clever ways. His work with mouthstick and balance have given him a notoriety in the circus world, often being referred to as "one of the world's top jugglers". In 2015, Dr. Salvador ...

Physical Trauma
An injury is any physiological damage to living tissue caused by immediate physical stress. An injury can occur intentionally or unintentionally and may be caused by blunt trauma, penetrating trauma, burning, toxic exposure, asphyxiation, or overexertion. Injuries can occur in any part of the body, and different symptoms are associated with different injuries. Treatment of a major injury is typically carried out by a health professional and varies greatly depending on the nature of the injury. Traffic collisions are the most common cause of accidental injury and injury-related death among humans. Injuries are distinct from chronic conditions, psychological trauma, infections, or medical procedures, though injury can be a contributing factor to any of these. Several major health organizations have established systems for the classification and description of human injuries. Occurrence Injuries may be intentional or unintentional. Intentional injuries may be acts o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bevel
A bevelled edge (UK) or beveled edge (US) is an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage they are often interchanged, while in technical usage they may sometimes be differentiated as shown in the image at right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, or aesthetics; or to facilitate mating with another piece. Applications Cutting tools Most cutting tools have a bevelled edge which is apparent when one examines the grind. Bevel angles can be duplicated using a sliding T bevel. Graphic design Typographic bevels are shading and artificial shadows that emulate the appearance of a 3-dimensional letter. The bevel is a relatively common effect in graphic editors such as Photoshop. As such, it is in widespread use in mainstream logos and other design elements. Glass and mirrors Bevelled edges are a common aesthetic nicety added to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scimitar
A scimitar ( or ) is a single-edged sword with a convex curved blade associated with Middle Eastern, South Asian, or North African cultures. A European term, ''scimitar'' does not refer to one specific sword type, but an assortment of different Eastern curved swords inspired by types introduced to the Middle East by Central Asian ghilmans. These swords include the Persian shamshir (the origin of the word scimitar), the Arab saif, the Indian talwar, the North African nimcha, and the Turkish kilij. All such swords are originally derived from earlier curved swords developed in Turkic Central Asia (Turkestan). Etymology The English term ''scimitar'' is attested from the mid-16th century and derives from either the Middle French ''cimeterre'' (15th century) or from the Italian ''scimitarra''. The ultimate source of these terms is corruptions of the Persian ''shamshir.'' ''Scimitar'' became used to describe all curved oriental blades, in contrast to the straight and double edged ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Toss Juggling
Toss juggling is the form of juggling which is most recognisable as 'juggling'. Toss juggling can be used as: a performing art, a sport, a form of exercise, as meditation, a recreational pursuit or hobby. In toss juggling, objects — such as juggling ball, balls, bean bags, juggling ring, rings, Juggling club, clubs, etc. — are throwing, thrown or tossed into the air and caught. Toss juggling is a form of object manipulation. Juggling techniques and patterns 'Toss juggling' has a number of basic principles and patterns. Most of the more complex patterns are variations of the basic ones and all toss juggling must conform to these basic principles. Basic principles Toss juggling is, according to most sources, the throwing and catching of objects, where there are more objects than there are hands (or sometimes other parts of the body) doing the throwing and catching. Three balls thrown and caught between two hands is toss juggling, as there are more balls than hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cascade (juggling)
In toss juggling, a cascade is the simplest juggling pattern achievable with an odd number of props. The simplest juggling pattern is the three-ball cascade,Bernstein, Nicholai A. (1996). ''Dexterity and Its Development'', p.379. . This is therefore the first pattern that most jugglers learn. However, although the shower requires more speed and precision, "some people find that the movement comes naturally to them," and it may be the pattern learned first. "Balls or other props follow a horizontal figure-eight hourglass figure] pattern above the hands." In siteswap, each throw in a cascade is notated using the number of balls; thus a three ball cascade is "3". "In the cascade...the crossing of the balls between the hands demands that one hand catches at the same rate that the other hand throws . The hands also take turns ..." Number of props Three-ball For the three-ball cascade the juggler starts with two balls in one hand and the third ball in the other hand. One ball is ...
