Water forms floating ‘bridge’ with high voltage

Austrian physicists discovered an unusual and unexpected effect liquid water is exposed to an electric field: a floating water bridge. The group from Graz University of Technology suggestes that the explanation may lie within the nature of the water’s structure.

Initially, the bridge forms due to electrostatic charges on the surface of the water. The electric field then concentrates inside the water, arranging the water molecules to form a highly ordered microstructure. This microstructure remains stable, keeping the bridge intact. 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.

The researchers also noticed a pattern with the inner structures: every experiment started with a single inner structure, which then decayed into additional structures after a few minutes of operation. The group thought that this decay might be caused by either dust contamination or the increasing temperature of the water bridge under the electric field. As the water temperature increased from 20 degrees Celsius to more than 60 degrees Celsius—which took about 45 minutes—the bridge collapsed.

This obvisouly reminds of The Abyss:

    Nice! Yet the idea is not quite original. William Beaty seems to have reported this “wasserfadden” as early as 1996, although without appealing pictures. http://amasci.com/freenrg/wasser.html
