The sport of ice hockey originated in Windsor, Nova Scotia, along Canada's east coast. It originated sometime around 1800, with the boys of King's College School transferring the field game of hurley onto the ice, where it became known as "ice hurley" and eventually "ice hockey."
An official hockey puck weighs between 5.5 and 6 ounces, has a diameter of 3 inches, is 1 inch thick and is made of vulcanized rubber. The National Hockey League is responsible for approving pucks that are used in games.
An Olympic hockey rink is 100 feet wide by 200 feet long. This is wider than a standard NHL hockey rink, which is 85 feet wide by 200 feet long.
