Water compresses under a high gradient electric field
Coincidentally, I just watched a great video by Ben Krasnow yesterday that suggests that the answer to fooker's question is indeed "Yes." There are other well-known principles along these lines, ranging from piezoelectricity to the Seebeck and Peltier effects, and it's almost more of a rule than an exception for such effects to behave symmetrically.Glowing plasma created by a high speed jet of water: https://www.youtube.com/watch?v=_vTq8oGpqwM&list=LLaIdy5TkkQ...
He definitely has the "whole lot of mechanical force" thing going for him, considering that he's about 2 psi away from fragging himself with a hydraulic cylinder.

⬐ ohiovrVery interesting experiment. I was wondering if you had tried a sapphire or diamond crystal target for the stream. The surfaces that you used look smooth, could it be that as the surface is erroded by the stream it gets rougher and this roughness impededs the effect? Could the beam be intense enough to marr diamond or even sapphire?
