This video has been around for a number of years. But for whatever reason…I still enjoy watching the process. It reminds me of being a kid when they used to have the ‘how its made’ vignettes on Canadian television on the weekends. If you are new to the game…you will find this somewhat interesting.
Hockey pucks are flat, solid, black disk-shaped objects made of vulcanized rubber. Regulation National Hockey League (NHL) pucks are black, 3 in (7.6 cm) in diameter, 1 in (2.54 cm) thick, and weighing 5.5-6 oz (154-168 g). The edge has a series of “diamonds,” slightly raised bumps or grooves. The diamonds give a taped hockey stick something to grip when the puck is shot. The blue pucks used in junior hockey are sometimes only 4 oz (143 g).
During a game, each team keeps a supply of pucks in a freezer at all times. When a professional hockey team receives their supply of pucks for a season, they are rotated so that the older pucks are used first. During games, pucks are kept frozen in an icepacked cooler, which usually sits on the officials’ bench. All pucks are frozen to reduce the amount of bounce.
