> In a National Hockey League rink, about how thick is the ice?And the answer: one inch. According to the NHL, "Ice is approximately 3/4 of an inch thick, and is usuallychilled at 16 degrees Fahrenheit.

However, this proved to be too dangerous for the refs, who (likely after acquiring some bruises) thought it better to drop the puck in instead. 2. The last time a goaltender played without a mask was just in 1974. As you might imagine, it didn't go great. Naturally, NHL rules have required face masks for goalies ever since. 3. Octopus throwing? You bet! Two American brothers started the tradition of “octopus throwing” during the 1952 playoff games. At that time, it took eight wins to claim the Stanley Cup, so the brothers thought it fitting to bring an octopus (with its eight tentacles) to the Detroit arena and toss it onto the ice. The Detroit Red Wings won the Cup, and the octopus has been a good luck charm in Detroit ever since. 4. Fans can be goalies too, you know. If a team’s two goalies are injured during a game, the rules state that anybody can play the position — including a fan from inside the arena!Learn more fun facts about ice hockey here[https://thefactfile.org/ice-hockey-facts/].
