Ice melts well below freezing temperatures

[Lost Generation SA]

If you put ice on the floor in a cold room, it will still melt after a certain amount of time. As far as I can tell the length of time isn't based on the amount of cryostylane you used, the ice just melts after a while. I've tried this on a floor tile in space, and in toxins, after hooking an air pump to the cooling port. That lowered the room to -43 degrees C, but ice on the floor still melted. Not sure what effect room temperature has on ice blocks, if any.
