Hockey pucks are kept cold before a game. How cold? And why?

Game pucks are made of vulcanized rubber and when warm they can be very bouncy! These freezers are kept at a temperature between 14F and 20F (-10C to -7C).

Each team has a freezer in their dressing room where they keep at least 80 game pucks at a temperature of 14F (-10C) the day before each home game. This will ensure the pucks delivered to the supervisor of the off-ice officials are frozen and ready for game use. Before the start of the game, fifteen pucks are taken from the home team’s freezer in a hard plastic cooler directly to the penalty box freezer. At the start of the second and third period, an additional fifteen pucks are taken again from the team dressing room’s freezer to the penalty box freezer, each time carried in a hard plastic cooler in order to keep them as cold as possible.
