I imagine that there wouldn't be much left to freeze, after shooting an Asian snakehead fish with .458 SOCOM out of an AR-pattern rifle. More like a "pink mist", than anytthing else.

This "barnacle" appears to be larger and bulkier than a "boot".
I would also image that it would be possible to puncture the the suction skirt and remove it yourself. Slide a knife under the edge and give them a few cuts, no angle-grinder required.

What is a little sad is that the push for modernity has made some parts of buildings worse in terms of spreading disease than traditional materials.
A good example is the simple door handle or pushplate, formerly made of brass which self-disinfects (I think it might be the copper in the brass, but I don't know) and now usually made from stainless steel which must be disinfected manually

I had the kind-of impression that filing a lawsuit against the Axanar production was more about being jealous that a fan-film is so much closer to the original source (the TV series) in look, feel & story than (at least) the last two big production official movies that it made Paramount look bad in comparison.
Have a look at "Star Trek Continues": it looks exactly like the original series and even has Chris Doohan (the son of James) as the chief engineer "Scotty".
It's a bit sad when low-budget (Even Axanar, at least in Hollywood terms) fanflics are figuratively lightyears ahead of the official Paramount productions.

After 14 years in zero G, they're gonna need a bucket for him back on earth, as he'd have no bones and few muscles left at all.

From the same country which has bans on toy and replica guns, and once upon a time banned Megatron from sale.

For the equivalent of $2400, I could get something custom made locally in a nicer fabric.

Good initiative!
He built a gravel road, which doesn't normally have curb & guttering anyway.
