Hockey puck


A hockey puck is a disk made of vulcanized rubber that serves the same functions in various games as a ball does in ball games. The best-known use of pucks is in ice hockey, a major international sport. A hockey puck has also been referred to as a "Flat Ball."
Ice hockey and its various precursor games utilized balls until the late 19th century. By the 1870s, flat pucks were made of wood as well as rubber. At first, pucks were square. The first recorded organized game of ice hockey used a wooden puck, to prevent it from leaving the rink of play. Rubber pucks were first made by slicing a rubber ball, then trimming the disc square. The Victoria Hockey Club of Montreal is credited with making and using the first round pucks, in the 1880s.
Many indigenous persons throughout North America played a version of field hockey which involved some type of "puck" or ball, and curved wooden sticks. It was first observed by Europeans being played by Mi'kmaqs in Nova Scotia in the late 17th century. It was called "ricket" by the Mi'kmaqs. Eventually, they began to carve pucks from cherrywood, which was the puck of preference until late in the century when rubber imported by Euro-Americans replaced the wood.
The "Flat ball" saying comes from Old England. It is believed by some that the sport of modern hockey was first conceived in Europe sometime in the late 1800s to early 1900s. It is believed that some Europeans were playing a form of hockey utilizing a round ball that had not been aired up properly. The ball was about 3/4 full, but they played on. Finding it more enjoyable they worked to make a flat ball that was easier to glide across the ice. They combined a flat wooden disk with a rubber outside coating around the middle. The exact thickness is unknown and no known pictures exist of the flat ball or play with it. It is unknown if this has any direct tie to the modern sport, but is believed by some to have inspired, or even have created the modern sport.

Etymology

The origin of the word puck is obscure. The Oxford English Dictionary suggests the name is related to the verb to puck used in the game of hurling for striking or pushing the ball, from the Scottish Gaelic puc or the Irish poc, meaning "to poke, punch or deliver a blow":
It is possible that settlers of Halifax, Nova Scotia, many of whom were Irish and played hurling, may have introduced the word to Canada. The first known printed reference was in Montreal, in 1876, just a year after the first indoor game was played there.
A hockey puck is also referred to colloquially as a "biscuit". To put the "biscuit in the basket" is to score a goal.

In ice hockey

Ice hockey requires a hard disk of vulcanized rubber. A standard ice hockey puck is black, thick, in diameter, and weighs between ; some pucks are heavier or lighter than standard . Pucks are often marked with silkscreened team or league logos on one or both faces. Pucks are frozen before the game to reduce bouncing during play.

Variations

There are several variations on the standard black, hockey puck. One of the most common is a blue, puck that is used for training younger players who are not yet able to use a standard puck. Heavier training pucks, typically reddish pink or reddish orange in colour, are also available for players looking to develop the strength of their shots or improve their stick handling skills. Players looking to increase wrist strength often practice with steel pucks that weigh ; these pucks are not used for shooting, as they could seriously harm other players. White pucks are used for goaltender practice. These are regulation size and weight, but made from white rubber. A hollow, light-weight fluorescent orange puck is available for road or floor hockey. Other variants, some with plastic ball-bearings or glides, are available for use for road or roller hockey.
Two major developments have been devised to create better puck visibility on television broadcasts, but both were short-lived:

Firepuck

The use of a "Firepuck" in the early 1990s was the first attempt to improve the visibility of hockey pucks as seen on television. This invention incorporated coloured retro reflective materials of either embedded lens elements or prismatic reflectors laminated into recesses on the flat surfaces and the vertical edge of a standard hockey puck. Yellow was the preferred reflected colour. A spotlight was required to be positioned on the TV camera and focused at the centre of the viewing area.
A short demonstration tape of the Minnesota North Stars skating with the Firepuck was shown during the period break at the 1993 NHL All-Star Game in Montreal. The International Hockey League pursued testing the Firepuck with its inventor, Donald Klassen. The next television viewing was the IHL All-Star Game in Fort Wayne, Indiana, January 1994, where the Firepuck was used for the entire game. The IHL tested the Firepuck in two more games, and finally the East Coast Hockey League used it January 17, 1997, for their all-star game.
The use of the Firepuck was discontinued because of these reasons:
The Firepuck name was branded during the 1990s but has since been discontinued.

Smart puck

The FoxTrax "smart puck" was developed by the Fox television network when it held National Hockey League broadcasting rights for the United States. The puck had integrated electronics to track its position on screen; a blue streak traced the path of the puck across the ice. The streak would turn red if the puck was shot especially hard. This was an experiment in broadcasting intended to help viewers unfamiliar with hockey to better follow the game by making the puck more visible. It was ill-received by many traditional hockey fans, but appreciated by many of the more casual viewers. The system debuted with much publicity in the NHL All-Star game at the Boston Fleet Center on January 20, 1996, but the system was shelved when Fox Sports lost the NHL broadcast rights three years later.

In game play

During a game, pucks can reach speeds of or more when struck. Zdeno Chára, whose slapshot clocked in the 2013 NHL All-Star Game SuperSkills competition, broke his own earlier record. The current world record is held by Denis Kulyash of KHL's Avangard Omsk, who slapped a puck at the 2011 KHL All-Star Game skills competition in Riga, Latvia with a speed of.
Fast-flying pucks are potentially dangerous to players and spectators. Puck-related injuries at hockey games are not uncommon. This led to the evolution of various types of protective gear for players, most notably the goaltender mask. The most serious incident involving a spectator took place on March 18, 2002, when a 13-year-old girl, Brittanie Cecil, died two days after being struck on the head by a hockey puck deflected into the crowd at a NHL game between the Calgary Flames and Columbus Blue Jackets in Columbus. This is the only known incident of this type to have occurred in the history of the league. Partly as a result of this event, the glass or plexiglass panels that sit atop the boards of hockey rinks to protect spectators have been supplemented with mesh nets that extend above the upper edge of the glass.

Manufacture

NHL regulation pucks were not required for professional play until the 1990–91 season, but were standardized for consistent play and ease of manufacture half a century earlier, by Art Ross, in 1940. Major manufacturers of pucks exist in Canada, Russia, the Czech Republic, the People's Republic of China, and Slovakia.
The list of former or present-day major producers includes
The black rubber of the puck is made up of a mix of natural rubber, antioxidants, bonding materials and other chemicals to achieve a balance of hardness and resilience. This mixture is then turned in a machine with metal rollers, where workers add extra natural rubber, and ensure that the mixing is even. Samples are then put into a machine that analyses if the rubber will harden at the right temperature. An automated apparatus, called a pultrusion machine, extrudes the rubber into long circular logs that are in diameter and then cut into thick pieces while still soft. These pre-forms are then manually put into moulds that are the exact size of a finished puck. There are up to 200 mould cavities per moulding palette, capable of producing up to 5,000 pucks per week. The moulds are then compressed. This compression may be done cold or with the moulds heated to for 18 minutes, depending on the proprietary methods of the manufacturer. They come out hard and then are allowed to sit for 24 hours. Each puck is manually cleaned with a trimmer machine to remove excess rubber. The moulding process adds a diamond cross-hatch texture around the edge of the puck for more friction between the stick and puck for better control and puck handling.
The practice pucks are made by a similar but faster process that uses larger pre-forms, thick, puts them into moulds automatically, and applies more pressure and heat over a shorter period of time to compress the puck into the standard size. This allows approximately twice as many pucks to be manufactured in the same time period as the more exacting production of NHL regulation pucks. People sometimes freeze pucks to prevent them from sticking to the ice.

In roller hockey

pucks are similar to ice-hockey pucks, but made from plastic and thus lighter. They have small ribs protruding from their tops and bottoms which limit contact with the surface, allowing better sliding motion and less friction.
Most commonly red, roller hockey pucks can be found in almost any colour, although light, visible colours such as red, orange, yellow, pink, and green are typical.
Roller hockey pucks were created so inline hockey and street hockey players could play with a puck instead of a ball on surfaces such as hardwood, concrete, and asphalt.

In underwater hockey

An underwater hockey puck, while similar in appearance to an ice hockey puck, differs in that it has a lead core weighing approximately within a teflon, plastic or rubber coating. This makes the puck dense enough to sink in a swimming pool, though it can be lofted during passes, while affording some protection to the pool tiles.
A smaller and lighter version of the standard puck exists for junior competition and is approximately 1 lb 12 oz and of similar construction to the standard puck.
While there are numerous regional variations in colour, construction and materials all must conform to international regulations stipulating overall dimensions and weight. The regulations state that pucks should be a bright distinctive colour, for example high-visibility pink or orange, and that for World Championships these are the only acceptable colours.

In other sports and games

The term "puck" is sometimes also applied to similar gaming discs in other sports and games, including novuss, shuffleboard, table shuffleboard, box hockey and air hockey.

Alternative uses

Ice hockey pucks of regulation diameter and thickness may be used as mechanical vibration dampening isolators in places such as feet for light industrial air compressors, and air conditioning units because they are of regulation materials and therefore consistent manufacture, size and shape, and are constructed of a repeatable and consistent vulcanized rubber material. Since the material is rubber, it may be drilled out or milled easily to a fixed depth as rubber feet or used as rubber spacer or gasket material. A very common use of a slotted hockey puck is as an adaptor between the metal foot of a trolley jack and the sill of an automobile. The sill has a spot-welded lip which fits into the slot of the puck and would otherwise be bent or marked by the metal foot. Hockey pucks have been used to level furniture, beverage refrigeration systems, wedding mementos, and as paper weights or door stops. The hockey puck has many uses other than its original, intended purpose by virtue of its consistent physical properties.
In November 2018, faculty of Oakland University in Michigan received hockey pucks and training to throw them as a possible last-ditch defense against active shooters. The American Association of University Professors distributed pucks to its 800 members, and is working with student groups to distribute an additional 1,700 pucks to students.
