What is a hockey puck made of?

A hockey puck is a disk-shaped object made of vulcanized rubber that is used in the sport of ice hockey. The puck is typically black, circular, and measures between 1 inch (25 mm) and 1.25 inches (32 mm) in thickness. It weighs between 5.5 and 6 ounces (156 and 170 grams) and has a diameter of 3 inches (76 mm).

Hockey pucks are designed to slide easily across the ice surface and are made to withstand the impact of being hit with hockey sticks. The vulcanized rubber used in making hockey pucks is durable and resilient, which allows it to maintain its shape and integrity even after repeated use.

Most hockey pucks have a textured surface to help players grip the puck and control its movement. The puck also has a flat bottom to ensure it moves smoothly across the ice and does not wobble during gameplay.

Overall, the hockey puck is a crucial piece of equipment in the game of ice hockey, as it is used to score goals and move the game forward.
