Hockey???????????

In Hockey what keeps the ice from melting? How does it stay frozen for 3 hole hours?|||Indoor ice making is a real art and Canadians (which I am proud to be!) are recognized as among the best in the world. The building itself (or arena) does not have to be below freezing, but the underlying concrete floor does. And through the concrete floor runs a network of pipes that have a brine solution pumped through them to keep the cement below freezing. On top of the floor water is flooded. It freezes and more water is flooded on to it. Ideally the ice thickness should remain fairly constant because thicker and thinner ice have different properties. Thick ice is softer because it is a bit warmer. In the professional league (NHL) the ideal thickness, I believe, is between 3 and 6 centimetres, or 1 to 2 inches. Zambonis are specially designed ice clearing and flooding machines that scrape a very thin layer of slush and snow off the ice and then replacing it with a thin coating of water that freezes within seconds of being applied. This process allows the surface, and immediate area inside the playing rink, to remain below freezing, while the bleacher area can be above freezing. That's why you see the hockey players have steam rising from their sweaty bodies while the fans in Row 25 are in t-shirts. Great question about the best team sport in the northern hemisphere!|||Whole.





And they make it cold in there!|||it's a cold blooded sport.|||i think there might be something like a freezer under it.|||The ice doesn't melt for the same reason that you have to wear think clothes and gloves. They keep it cold inside of the rink your pretty much skating inside of a freezer.|||The same technology that keeps your freezer cold - but on a larger scale.|||Simple: there is a refrigeration system below the ice. Pretty much the same thing that keeps things frozen in your freezer, only bigger!|||It's artificial...................that's how!|||This is all you need to know about rinks...
