'Floating Bridge' Property of Water Found
eldavojohn writes "When exposed to high voltage, water does some interesting things. From the article, 'water in two beakers climbs out of the beakers and crosses empty space to meet, forming the water bridge. The liquid bridge, hovering in space, appears to the human eye to defy gravity. Upon investigating the phenomenon, the scientists found that water was being transported from one beaker to another, usually from the anode beaker to the cathode beaker. The cylindrical water bridge, with a diameter of 1-3 mm, could remain intact when the beakers were pulled apart at a distance of up to 25 mm.'"
One would imagine that, firstly, the cell walls could not take too much expansion and would likely ditch a lot of the water, secondly, that the cell walls would return to normal at the same speed as the water (if they matched the expansion, then why not the contractions?) and that, thirdly, one of the biggest cryo problems is that the water surrounding the cells become crystals and pierce the fragile cells, which this does nothing to alleviate.

Actually the problem with freezing isn't the expansion, the cells could stretch enough to allow that. The problem is the ice crystals that tend to slice up the cells like a million tiny rasor blades. A further problem is cracking of the ice while it's going from freezing down to liquid nitrogen temperature.
Given that helium is a monatomic gas, nonpolar, and far less dense than water, I would have to say... no.
Oh, and then there's the fact that we already understand superfluid helium pretty damn well.
The water in the research at hand is clean (distilled) to a high degree, to avoid ionic conductivity. The water in living cells is VERY conductive and when you use high direct voltages, does Bad Things to these cells.
Now, high grequency alternating voltage would cause no adverse effect because it would cause for the electric current to flow on the surface of the body, but that's another story, and it does not affect the fluid inside the cells (think Tesla holding a glowing gas discharge lamp in his hand).

Human cells have membranes, not walls. Only plants and bacteria have walls.
Ah, damn... I'm going to have to shoot my TV again.
Good one. Very Insightfull.

The point at which water and steam are the same is a line, actulally of pressure, that goes down to its 'Triple' point. Where without a change in potential, H2O can exist in all three phases. If you increase its pressure/temprature way up, like you say to 340^o C, then all the electrons cannot attach themselves to the molicules, and the electrical properties are lost, and the gas enters the fouth state of matter called
Seems that some gases when exposed to electrical current, at room tempretures, when they strip their electrons off, give off diffrent wavelengths of light... so if you can arrainge them in a matrix, you have a Plazma TV/Display.
Uhh.. There is a problem with Heavy water. Really bad to drink... Particularly hard-hit by heavy water are the delicate assemblies of mitotic spindle formation necessary for cell division in eukaryotes. Regular tap water gives off neutrons too, but not in any sufficent quantity to be dangerous. Almost undetectible from the backround radiation. A molocule of heavy water is about 1 in 41 Million. so to get a gallon of heavy water, you need to process at least 4 times that amount.
Think 10 days of clean mississippi flow.
(And you did guess right about the number of types of ice. Of course there is a S.F. Book called Ice-9, but its fictional)
If you take water, as steam, and swril it around a cylinder, the heaver molocules will move to the sides, where you can siphon them off. Turns out that 90cm are about right for this. SO when a county like Iraq starts ordering up a storm of 90cm alumium tubes...
BUT, inorder to get enough water to seperate out the heavy molocules, you need an enoumus water source. In Germany, they used alpine rivers as the water source. In Iraq, you would need an extrodinarly large amount of fresh water to putify out the heavy water, and by the time the Tigrus and Euprhaties rivers reach Bagdad... the water is sufficently polluted to make it unusable for heavy water production. Now, if you had a place with heavy rainfall, little air pollution, like North Korea, you can make lots of heavy water, and of course sell it to the Iraqis.
It realy doesnt take much to figure this stuff out.
Why, an endless stack of turtles, of course...

I find it scary that someone actually found that informative.
