Utility Ball
The utility ball (also known as a playground ball or named after the games in which it is used, such as dodgeball and kickball) is a spherical, inflated ball used in several kinds of playground games and sports. Utility balls were introduced in the mid-20th century and have continued to be used in various games. History The first dedicated utility balls were introduced by American manufacturer Voit shortly after World War II and became popular within a few years, being adapted to several games such as dodgeball and kickball that had previously been played with harder objects, like basketball (ball), basketballs. The softer ball was safer and easier to adapt to other games, such as four square. Specifications Utility balls are typically made of polyvinyl chloride or rubber and have a diameter of and weigh between . The balls are often made with ribbing for grip and are inflated to .

Ball
A ball is a round object (usually spherical, but sometimes ovoid) with several uses. It is used in ball games, where the play of the game follows the state of the ball as it is hit, kicked or thrown by players. Balls can also be used for simpler activities, such as catch or juggling. Balls made from hard-wearing materials are used in engineering applications to provide very low friction bearings, known as ball bearings. Black-powder weapons use stone and metal balls as projectiles. Although many types of balls are today made from rubber, this form was unknown outside the Americas until after the voyages of Columbus. The Spanish were the first Europeans to see the bouncing rubber balls (although solid and not inflated) which were employed most notably in the Mesoamerican ballgame. Balls used in various sports in other parts of the world prior to Columbus were made from other materials such as animal bladders or skins, stuffed with various materials. As balls are one of t ...

Voit
Voit (official name: "Industrias Voit S.A. de C.V.") is a sports equipment manufacturing company based in Mexico. The company was founded by German American entrepreneur William J. Voit (1880–1946) of Worthington, Indiana. The current range of products by Voit includes balls (for association and American football, basketball and volleyball), and also goalkeeper gloves, tennis rackets, football uniforms, shin guards, and swimming equipment ( suits, goggles, caps, and fins) and accessories (backpacks, bags). History Voit began in Los Angeles in 1922 as a tire retreading products factory. In the late 1920s Voit developed and patented the first full-molded, all-rubber inflatable ball and the first needle-type air retention valves. They also developed highly accurate pocket and wrist watches during this period. In 1931, Voit developed and patented the first all-rubber athletic balls, including the process of vulcanization which allowed a material to be fixed onto a separate ...

Dodgeball
Dodgeball is a team sports, team sport in which players on two opposing teams try to throw balls and hit opponents while avoiding being hit themselves. The objective of each team is to eliminate all members of the opposing team by hitting them with thrown balls, catching a ball thrown by an opponent, or inducing an opponent to commit a violation, such as stepping outside the court. The sport is mostly played in schools under varying rules, and also formally as an international sport, under rules that vary among international governing bodies, such as the World Dodgeball Federation (WDBF), which runs the Dodgeball World Championship and the World Dodgeball Association (WDA). USA Dodgeball is the governing entity for dodgeball in the United States, with member leagues and clubs across the nation. Equipment There are many different ball types used around the world, including rubber, "no-sting" rubber, foam and cloth; versions made with rubber or polyvinyl chloride are termed util ...

Kickball
Kickball (also known as soccer baseball in most of Canada and football rounders in the United Kingdom) is a team sport and league game, similar to baseball. Like baseball, it is a safe haven game in which one team tries to score by having its players return a ball from home base to the field and then circle the bases. Meanwhile, the other team tries to stop them by tagging them "out" with the ball before they can return to home base. However, instead of hitting a small, hard ball with a bat, players kick an inflated rubber ball; this makes it more accessible to young children. As in baseball, teams alternate half-innings. The team with the most runs after a predefined number of innings wins. Kickball is typically played among young, school-age children, both as a playground game and as part of physical education (PE). The lack of both specialized equipment and highly skill-based positions (like the pitcher) makes the game an accessible introduction to related sports such ...

Four Square
Four square (also called handball, champ, four squares or box ball) is a global sport played on a square court divided by two perpendicular lines into four identical boxes creating four squares labelled 1–4 or A–D. Four square is a popular game at elementary schools with little required equipment, almost no setup, and short rounds of play that can be ended at any time. The game also has a large following for adults in many communities. History Four square dates to at least the 1950s. A game called four square is mentioned in newspapers in the northeastern United States at least as far back as the 1950s, but the rules are not explained. A 1953 teacher's manual describes four square with the same rules used today. However, it is possible this game could have evolved from " Jeu de paume", a game popular in France as early as the twelfth century. Rules One player occupies each of the 4 squares at a time; the other players wait in line. The player in square 4 serves the ball i ...

Close-up Of An Orange Playground Ball
A close-up or closeup in filmmaking, television production, still photography, and the comic strip medium is a type of shot that tightly frames a person or object. Close-ups are one of the standard shots used regularly with medium and long shots (cinematic techniques). Close-ups display the most detail, but they do not include the broader scene. Moving toward or away from a close-up is a common type of zooming. A close up is taken from head to neck, giving the viewer a detailed view of the subject's face. History Most early filmmakers, such as Thomas Edison, Auguste and Louis Lumière and Georges Méliès, tended not to use close-ups and preferred to frame their subjects in long shots, similar to the stage. Film historians disagree as to the filmmaker who first used a close-up. One of the best claims is for George Albert Smith in Hove, who used medium close-ups in films as early as 1898 and by 1900 was incorporating extreme close-ups in films such as ''As Seen Through a Te ...

Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...

Funnel Ball
Funnel ball is a playground game where a ball is thrown into a funnel with multiple exit holes. A relatively large fiberglass or plastic funnel, roughly in diameter with a 50 degree pitch, is placed atop a post. The exits of the funnel are multiple holes or tubes, projected parallel to the ground, and spaced equally around the bottom. Play consists of tossing a ball (such as a basketball or small medicine ball) into the mouth of the funnel and waiting for it to exit through one of the holes. Each hole is marked with a point value, e.g. 2, 4, 6, and 10 points. The ball usually rolls around inside the funnel for a short time, making the outcome of the shot nearly random In common usage, randomness is the apparent or actual lack of definite pattern or predictability in information. A random sequence of events, symbols or steps often has no order and does not follow an intelligible pattern or combination. ..., and shots which exit through the desired hole are unlikel ...
