The renowned Ice Castles has returned to the area for its sixth season. Located in Woodstock, NH, the astounding attraction spans across more than one acre and weighs over 25,000,000 pounds. As soon as temperatures drop in the Fall, the Ice Castles crew begins using their patented ice growing technique to produce more than 10,000 icicles every day. Each icicles is placed throughout the Castle and provides something for the water to freeze to. Over time these icicles are absorbed into the ice structure. A commonly asked question is why the ice is blue. Well, simply, ice has the same color properties of water. Ice is blue for the same reason that the ocean is blue - because water will absorb every other color of the spectrum except blue. A general rule is the thicker the ice, the deeper the shade of blue. Nothing is added to give the ice a blue tone. If you haven't had the opportunity to visit, put this on your list for this winter. They open for the season on Friday, January 10th but are, of course, weather dependent so there is no posted close date. Think ahead and get your tickets on-line - especially since they often sell out on the weekends. And don't forget to dress warm from head to toe! Purchase tickets here.
