Hi MArtin,

I'm not sure I follow your question.  It seems that the rotating wand 
would be like a dishwasher spray wand ?  it would have many different 
holes and they would be angled so the more pressure, the faster it 
would spin ?

When you mentioned spinning, the first thing that came to my mind 
would be to have a shaft that came out of the enclosure
and that would have a motor on it.

But that would mean a circular spray pattern if the want rotates in a 
circle.

dunno what your project looks like.

But, I would be careful about having ANYTHING under pressure that was 
NOT in a secondary containment vessle of some sort.  If a fitting or 
tube were to leak, there should be some means of containing the spray 
as well as the fluid.

I would not like any Xenomorph blood on my carpet.
