This is a regular water fountain of minimal design with the only
characteristic design feature being that the several spouts of
water
are rifled the way pee is when it exits the urethra. (See linked
rifled
urethra idea.) so pee seems to come out in a vaguely helical
stream,
so imitate and
exaggerate this using materials science and
experimenting with different shapes and sizes to optimize the
interest factor. You use more water but you get crazy interesting
fountains.
(Amended to be slow-motion space pee fountain, limited in size to
6 inch spouts or so and moved to space to take advantage of
gravityless environment. So this would be a fountain that takes
advantage of and explores the possibilities provided by the surface
cohesion of water)

There is a problem with this, but it's only basic
physics so feel free to carry on. |
|
| |
Just don't do it in a public place. |
|

What about fountains A through O, and Q through Z ? |

Come to think of it, based on 21quest's comment on the
rifled urethra idea, maybe this would work best on a
relatively small scale at a pressure similar to urinary
pressure. If the stream starts to separate into turbulent
chaos at 6 or 7 inches then maybe the forces that hold that
interesting helical structure together in the first 6 inches of
the stream would only ever work at that scale. Maybe it is
surface tension. And it is interesting to think what kind of
effects could be gained in space. |

Ah, slow motion space pee fountain. |

I'm pretty sure you can't create a helical stream, over
any distance at all. In fact, I will wager [8th]'s Blue
Peter Badge that you can't. |

What about with a rotating spout? |
|
| |
That would be cheating. Any one bit of water would
still travel in a straight line. |
|
| |
A truly helical stream would look stationary, in the
same way that you can't see that a bolt thread is
moving as you turn the bolt. |
|
| |
You could create the illusion of the stream being stationary
by using a total internal reflection strobe light. |

Change the fluid to a ferrofluid. Act upon it with some highly-tuned magnetic waveform. |

Freeze the liquid as it emerges from the spout. |
