1. An Old Obsession: Water and Its Secrets
Water is everywhere. Simple, transparent, seemingly ordinary. And yet, for centuries, it has baffled even the most brilliant scientists. One of them was William Thomson, better known as Lord Kelvin, a towering figure of 19th-century physics.
Kelvin, famous for his work in thermodynamics and for lending his name to the absolute temperature scale, also speculated that water could exist in "ordered" structures, built from complex molecular networks. Though far from modern chemistry, his ideas opened a door to a world where water might not always be just water.
"Pure water is perhaps the only substance whose properties vary so drastically from what theory predicts." – Lord Kelvin (attributed)
In these early reflections, we glimpse the theoretical seeds of polywater, a supposed new form of water that would cause a sensation nearly a century later.
2. From Victorian Labs to Soviet Mysteries
Jump forward to the 1960s, in the heart of the Cold War. The world is split between East and West, and even science becomes a battleground of ideologies. In the Soviet Union, unconventional research is encouraged, hoping to uncover revolutionary phenomena—and perhaps beat the Americans in the process.
In this fertile (and chaotic) environment, Soviet scientists like Nikolai Fedyakin and Boris Derjaguin begin to observe strange behavior in ultra-purified water. When passed through narrow quartz capillaries, the liquid seemed to transform.
The result? A substance that was allegedly:
-
Denser than regular water (by up to 10%)
-
Freezing at much lower temperatures (as low as -30°C)
-
More viscous
-
Optically different
It appeared to be a new state of water, with molecules linked in a polymer-like structure. Hence the name: polywater.
This supposed discovery caused a stir in the USSR. Entire conferences were dedicated to it. Military and biomedical applications were considered. Some even whispered that polywater could become a strategic substance in the Cold War.
3. Polywater’s Rise: Between the Lab and Legend
For a few years, polywater was the crown jewel of Soviet research. Derjaguin and others published studies describing its strange properties, and the scientific community reacted with a mix of awe and suspicion.
In the West, the response was more cautious. Scientists attempted to replicate the experiments, but results were inconsistent. Still, some voices urged attention. Was this truly a new phase of matter?
Publications like Nature began to reference polywater, and even US scientists debated its nature in academic circles. The fascination was real—fueled by mystery, political rivalry, and a natural desire for scientific breakthroughs.
4. The Collapse: When Science Self-Corrects
By the late 1960s, cracks began to appear. Several labs failed to reproduce the effects. Some suspected contaminants or experimental artifacts. A 1970 study in Nature delivered a serious blow: when experiments were done with rigorous controls and inert containers, the anomalies disappeared.
No special form of water. Just trace impurities—perhaps from quartz, silicon, or even the air.
Even Derjaguin later admitted that the effect had likely been overinterpreted. Within a few years, the entire phenomenon was quietly shelved. Polywater became a scientific footnote.
5. What Polywater Taught Us
Though now seen as a scientific error, the story of polywater remains deeply instructive.
-
It’s a lesson in the importance of reproducibility and rigorous methodology.
-
It shows how context—political, cultural, institutional—can shape science.
-
It stands as a rare case of pseudoscience born within the mainstream, not outside it.
Above all, it reminds us that science is not absolute—it’s a process. One that includes mistakes, corrections, and continual learning.
6. Why the Myth Still Fascinates
Even today, the idea of structured water, “water with memory,” or exotic liquid states pops up in alternative circles. The myth persists, perhaps because water still holds so many secrets. It is both commonplace and enigmatic, and stories like polywater feed our sense of wonder.
Polywater may be gone from the lab—but it lives on as a legend.
