Hi all! Here I am at the bottom of the Mariana’s Trench (shhh! my girl thinks I’m in Texas today!).
Because I am a highly inquisitive sort who frequently posts to the SDMB and devours the GQ section in particular, I know that water doesn’t compress appreciably and so is just as dense down here as it is near the suface. In the claws of my deep sea submersible I have a 1 gallon empty Miracle Whip jar (glass) which I am filling with Mariana’s Waters to give to my girl as a reminder of the depths I will go to on her account. Well, and I don’t have the bread for a diamond for her, but always have enough bread for…yeah, ok, stupid joke.
Anyways. My jar will have exactly 1 gallon of non-compressible Mariana’s Water in it as me submersible’s claw screws the lid back on. Oh look! There’s a little Paraliparis australis (let’s not worry about why it’s here in the trench, mmkay?) in the jar! Say hi to the little fishy!
Since I have other business down here in the trench I’ll send my jar of fish & water up to the surface on the express elevator, a separate vessel that goes straight to the surface with no decompression stops.
Something bad happens to my fish on the way up, but why? Water doesn’t compress, so there is still the same amount of water in my jar as before, so the fish couldn’t expand & pop. And if my jar fails, how? It never had any more than 1 gallon of water in it … did it?
