The enigmatic poliwater: great discovery

One of the most controversial cases occurred in the late 1960, when a group of scientists at the Institute of Chemical Physics in Moscow announced the discovery of a new form of water.
There was a theoretical speculation: SONET displaying photographs of their trials and provided small samples in fine quartz tubes.

Boris V. Deryagin, one of the greatest experts in chemical surface, this discovery led to the West, who had made the physicist Nikolai Fedyakin.
His talk in the classic "Discussions of the Faraday Society", held in 1966, scientists capitalists made aware of their wonderful properties: Hervé at 150 ° C, frozen at 40 ° C and issue a viscosity comparable to syrup.

What happened was peculiar. Imagine that sealed a little water within a hair of quartz. The liquid reaches a certain height, but soon a second column appears at the top of the tube that seems to be growing at the expense of which is located underneath.
It is not strange to assume that part evaporates and condenses above, but the pressure and temperature inside the tube must be the same anywhere, so there is no reason for the water to behave that way.

The only way to explain it is assumed that the liquid from the upper part different from that goal in the capillary. Does this mean that a liquid may take another structure? After all, this happens with ice ... That was the reasoning of the Russians.
