puck

The puck is a vulcanized rubber disk, typically 1 inch thick and 3 inches in diameter, used in ice hockey. It is propelled across the ice rink by players using hockey sticks, with the objective of scoring by getting the puck into the opposing team's net. The word "puck" likely originates from an Irish word related to a stroke in the game of hurling. Early versions of ice hockey used balls or flat blocks of wood before the standardized rubber puck became common. The puck's design has seen some modern enhancements, such as embedded sensors for tracking, though these were not widely adopted.123
