For this warm blooded Queenslander, that is just too cold for anyone's own good!!
Those are great shots Sheeny but they do raise a question. In the close ups of the ice block, there are cavaties. I'm assuming that these cavaties are made from pockets of air.
If so, then how did they get preserved? Surely the water did not freeze instantly, which it would have to do in order to preserve the bubbles of air.
What is going on here? Why is it so?
BTW, if anyone tells me that atmospheric pressure does the work...
