I didn't consider it that way. I thought it was just ice made from water.
You have to remember that the atmosphere gets thinner in terms of life giving for us. It becomes less dense and less agitated.
Think of a helium balloon under inflated and released into the atmosphere.
It expands as it rises. Why?
Because the helium is broken down atmospheric matter into it's much more expanded for but then itself is compressed and contained, then released into a balloon (in this case) and placed into the atmosphere.
The balloon itself does not rise. The atmosphere acts just like the sea does. It tries to crush it but in doing so only crushes it up due to the helium being massively less dense than the atmosphere it was placed in at sea, lower level.
As that balloon rises it is always being crushed and always rising because of it but as it rises it's always rising into less dense atmosphere. Thinner more expanded atmospheric matter which also allows the helium molecules to start expanding themselves, which is why you see the balloon gain in size.
Once that helium and balloon skin, etc, becomes equalised with the above atmosphere it gets breached and the material of the balloon and whatever was with it is now pushed back down. The helium inside would then expand a little more and take its place in the higher atmosphere.
What is a superfluid? I've never heard the term with my limited knowledge of chemistry/physics
A super fluid is where an element (let's use helium/hydrogen as a yardstick) hits a spot where it is in a state of attempted freeze but is in such low pressure but with some energy still creating a friction, causing it to expand and contract.
Basically this would be what is happening on the dome.
This can create a sort of icicle or many.
A superfluid and then a freeze as the energy passes.
