So, I decided to do a little project of my own.
THE UNDERWATER UTOPIA!
...sort of.
But, in order for it to work, (Totally self-sufficent) I needed a way to farm. And in order to farm, I needed a muddy surface. And in order to get a muddy surface, I needed water.
I embarked on a ocean-side fort, with grand dreams of testing out my new prototype under-water farming room on the bottom of the ocean.
What I didn't plan on, was water pressure.
*Starts smoking pipe*
I remember it perfectly.... a day in timber, or day-abouts.
I had just finished the water room and drainege room (I would fill the farm room with 7/7 water first, then open some floodgates leading to the huge drainige room downstairs.) and was eager to test it out.
The moment I pulled the lever, I knew something had gone wrong.
Sure enough, when I checked back down at the farm room, I realized that I had forgotton to install a door on it leading to the rest of the fort.
...
It was sort of a "OOOOOOOOOOOH SHIIIIIII-" moment, but in slow motion.
...
The water pressure was so bad (good?) at the bottom of the ocean, that the farm room instantly filled with 7/7 water, then the rest of the fort 3 seconds later.
The water had come out so fast, that it actually shot out of the main shaft, like a fountain.
The lones dwarf outside thoughts of suacide had quickly been driven out with the realization that there was now a fountain with mist next to him.
