Source-derived summary

Polywater was a hypothesized polymerized form of water that was the subject of much scientific controversy during the late 1960s, first described by Soviet scientist Nikolai Fedyakin. By 1969 the popular press had taken notice of Western attempts to recreate the substance and sparked fears of a "polywater gap" between the United States and Soviet Union. Increased press attention also brought with it increased scientific attention, and as early as 1970 doubts about its authenticity were being circulated. By 1973 it was found to be illusory, being just water with any number of common compounds contaminating it. Today, polywater is best known as an example of pathological science.

Background

In 1961, the Soviet physicist Nikolai Fedyakin, working at the Technological Institute of Kostroma, Russia, performed measurements on the properties of water which had been condensed in, or repeatedly forced through, narrow quartz capillary tubes. Some of these experiments resulted in what was seemingly a new form of water with a higher boiling point, lower freezing point, and much higher viscosity than ordinary water – about that of a syrup.

Boris Derjaguin, director of the laboratory for surface physics at the Institute for Physical Chemistry in Moscow, heard about Fedyakin's experiments. He improved on the method to produce the new water, and though he still produced very small quantities of this mysterious material, he did so substantially faster than Fedyakin did. Investigations of the material properties showed a substantially lower freezing point of −40 °C or less, a boiling point of 150 °C or greater, a density of approx.

Editorial summary

This brief starts where responsible research should: with the source description of “Polywater” as hypothetical polymerized form of water. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1969, 1970, 1973, 1961—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Polywater, hypothetical and polymerized can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as hypothetical polymerized form of water. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q1890780. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1969, 1970, 1973 and 1961.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
