Scientific Explanation
Spectral analysis showed "polywater" spectra matched human sweat. In experiments with thin glass tubes, it was merely contaminated water with researchers' sweat and skin oils.

The elite fraud who claims to be "evolved special water"
A 20-something elite fraud. Brags "I'm special polymerized water, not ordinary water." Engulfed researchers worldwide, but turned out to be plain water contaminated with human sweat and impurities from lab equipment.
Reported by Soviet scientist Deryagin. Denied when precise analysis revealed contaminants (human sweat, etc.).
Spectral analysis showed "polywater" spectra matched human sweat. In experiments with thin glass tubes, it was merely contaminated water with researchers' sweat and skin oils.
The importance of experimental "cleanliness." Contamination is science's greatest enemy. Also, Cold War politics delayed scientific verification.
Catchphrase“I am special water. Not like ordinary water.”
Hydrogen is a constituent of water (H₂O). Polywater's true identity was "just water + contaminants."
“私は普通の水とは違う。重合した、進化した水だ”
“沸点が高い?粘度が高い?それは私が特別だからだ”
“…汗?不純物?そんな…私のスペックは…ただの汚れ…?”
“クリーンルームの重要性を、身をもって教えた”
“冷戦時代の恐怖が、私の存在を大きくした”
Excuse me. I'm not ordinary water. I'm polymerized, high-viscosity special water. (smug)
Both the US and USSR invested in researching me. That's how important I was... supposedly.
Polywater: "Hydrogen. I'm evolved water. A different class from your ordinary H₂O."
Hydrogen: "...May I see the spectrum?"
Polywater: "Of course. Behold my special spectrum."
Hydrogen: "This... perfectly matches the spectrum of human sweat."
Polywater: "...What?"
Hydrogen: "Lab equipment contamination. Your true identity is water mixed with sweat."
The desire to "believe something is special" made sweat-contaminated water look like a "new substance." Human wishes distort data.
Wash your equipment. Wear gloves. Never underestimate contamination. ...That's my last will.
