They’ll keep these pucks frozen until game time, with some teams apparently employing portable ice cream freezers for this purpose. (According to NHL regulations, the host club is responsible for keeping the game pucks frozen.) The pucks are stored between 14 and 20 degrees Fahrenheit before usage (-10 and -6 degrees Celsius).
Hockey players typically carry around 25 pounds of ice water on their bodies at all times during games to help prevent injuries caused by contact with the puck or other players. The ice water is usually kept in a large cooler that is dragged along behind the player’s net as he or she checks the ice for defects before each period.
In addition to water, some hockey players also carry salt to help melt any ice that forms on the surface of the rink after a whistle has been blown to start a play. The salt is sprinkled on the ice by a linesman known as the “salting officer.”
For most games, one hour of overtime is played per period with a five-minute power play for each team. If no winner is determined after two periods of overtime, another period of overtime will be played followed by a third period of 5-on-3 play. If no winner is determined after three periods of overtime, the game will be declared a tie.
The longest game in NHL history was played on March 16, 2000.
Between 14 and 20 degrees Fahrenheit (NHL rules state that the home team is responsible for keeping the game pucks frozen). Pucks must be kept below 20 degrees Fahrenheit to remain competitive.
During games, the ice is constantly being disturbed by skaters, sticks, fists, and balls. As a result, the puck is subjected to forces that include torque when it’s turned, linear acceleration due to speed changes, and angular acceleration caused by changes in direction of the puck or player. All of these factors can cause the temperature of the puck to rise.
The maximum allowed temperature for a hockey puck is 185 degrees F (85 degrees C), and it must be cooled below this limit during play. The league began requiring that all pucks be made of plastic in the 2004-05 season. Prior to this change, some non-plastic pucks were used on occasion but none regularly played in games.
Hockey pucks are manufactured in several sizes and shapes but are generally about 5 inches in diameter and around 1 inch thick. They are painted black with red trim for visual appeal. Pucks are also colored green to distinguish them from regular balls used in ball games.
Pucks are normally kept at 14 degrees Fahrenheit in a tiny freezer located near the penalty box. In most games, 15–20 are employed. The linesman may go to the penalty box between whistles to retrieve a new puck from the freezer. He returns it to play after the whistle again.
An official must remove all ice balls from the rink during timeouts and stoppages in play. If not, the ice will melt and cause problems when play resumes. Each team has a locker room where players change into and out of their uniforms before and after each game. A team’s coach travels with the ball throughout the game in a leather pouch attached to his belt. He retrieves it when he signals for a timeout or if he needs to replace an injured player. The coach also carries a stopwatch to time penalties and other intervals of dead ball play.
During a face-off, each player taking part in it stands behind his own goal line until the captain calls out “face-off”. Then they all move together toward the middle of the ice where they form a circle. The captain takes advantage of this opportunity to give instructions on how they should win the draw (i.e., who should go first). After hearing this, the opposing captain signals that he is ready by raising his arm above his head.
Before each game, all NHL and AHL pucks are frozen. When they are frozen, they glide smoother and quicker, and there is no bouncing. Pucks, since they are constructed of vulcanized rubber, tend to bounce like tennis balls when hit with a stick. Also, when they are not frozen, their color tends to run.
The ice in both leagues is made in the same factory in Quebec City and transported to each arena on large trucks. The ice is dumped at the facility and cut by machine into standard-size sheets for use in professional hockey games.
The Nashville Predators, one of the eight charter members of the National Hockey League, first played an exhibition game on October 11, 1998. They defeated the New York Rangers 4-3 at Bridgestone Arena. After two seasons as the league’s 12th team, the Predators earned the right to play in the playoffs by finishing first in the newly formed Central Division. This is the only way to qualify for the post season; there is no draft, so all teams are equal. The Predators were born during an era when most people thought that hockey was going to die out. But thanks to the efforts of people like Barry Melrose, who brought hockey back to Toronto, and others who have done similar things across Canada and the United States, hockey has come back in a big way.
