How long would it take for a blob of mercury (the size of a marble or so) to freeze in space? I'd emagine it would have to boil in some way first, and that would send pieces of it flying around, but the surface tension of mercury is much greater than that of water, or urine (as we'd seen evaporate and then freeze into fine crystals). I'd imagine the effects of mercury in space would be the similar to those of urine, except the crystals might be less fine perhaps? ..Or might the whole blob just freeze solid?? I cannot find any clear answer to this online, so I thought I'd ask because I'm no pro, and if somebody here can help me out, it would be greatly appreciated!
