Say, Bill Beaty's experiments made it as a reference on wikipedia!

Yes, this experiment was made by others too and published in science
journals.
It must be seen that a strong current flows through the water thread.
This means there is a voltage gradient in the water thread. If the
threa becomes thinner, the resistance will increase and at this
position the voltage will increase and electrostatic forces pull the
thread together.
So the thread is in an dynamic equilibrium of electrostatic forces
and pinching.
In some videos it can be seen that the thread becomes boiling hot.
Ethanol does also conduct some electricity, also glycol and glycerine.
The resistance is some megohm between to wires in the fluid.
I believe, the effect is not specific to water and could be done with
these fluids also.
I tried it, but my HV source did not deliver enough power.
This experiment consumes some ten to hundred Watts.

Bill Beaty's water threads consumed very little power. He used an
about 10 micro-amp negative ion generator power supply, at 10-15 kV.

I dont believe, he used this for the water thread experiment.
This needs more current.
I tried with deionized water, but my supply was too week. It should
deliver about 100µA.
Its a TV split diode flyback transformer driven by a selfbuild electronics.
