@CharlieC I now have this image of fish swimming around my shells to make the tank a bit more 'homey', a real 'fish-tank'
I was thinking of the issues having wet-acid batteries caused in WW2 armor, any little defect or damage to that battery case was potentially nasty for anyone in the tank.
The same could apply to a liquid filled rack, leaks onto ice-cold metal+condensation I suspect could be potentially nasty, if a frozen leak could hold a shell in place, even a few seconds messing about could be a big problem.
& OT talking of problems, gotta luv the guy in front of this tank, his posture just seems to say 'OK you got me...'
