I know of only one type of building you *might* be able to turn into an aquarium by stuffing towels under the door and leaving all the taps running.
It certainly ain’t that rattly old bathroom above a wooden theatre.
You’d probably need a steel frame building with an air tight contiguous outer glass shell.
Even then, I’m not sure it will work.
But, I’d be willing to give it a go. You know…. for science.
