Hey guys, I have a question.... first some backround. I am asking this question is so I can build a backyard skating rink in the fastest way possible. I live in south Jersey so winter is allot of freeze/thaw. The common way for a backyard rink is 1) place a liner 2) fill 2-3 inches 3) let freeze. This way, however, is tough in my climate because I would need many days of sub freezing temps to get a good slab of ice. So....I want to build it up 1 mm or cm at a time, while the temp is right, instantly adding the next layer as soon as the previous one freezes thereby saving time. Questions: 1) is there a set formula to figure how fast 1 cm will freeze? 2) does surface area matter ? (Im sure it does) 3) how does the time to freeze change as temp drops lower Thanks in advance for any help.
