Under normal circumstances, pure, distilled water (water removed of impurities such as salt) cannot conduct electricity due to its loosely linked molecules and bound valence electrons. But put water in an environment of extreme pressure, such as in the cores of giant planets like Jupiter, and it goes into a metallic phase, with its electrons behaving like free electrons in a conduction band. This fact on its own is already amazing. However, recreating this phase transition of water is more amazing, and this just happened for the first time ever.
Using the electron storage ring BESSY II, a group of 15 scientists from 11 research institutions have successfully produced a aqueous solution with metallic properties, but with a different method. Instead, the scientists experimented with alkali metals, putting a tiny amount of water into a sodium-potassium alloy (which is liquid in room temperature.)
According to the report by Dr. Robert Seidel, the scientist who supervised the experiments at BESSY II, this phase transition of water could even be seen by the naked eye.
Siedel states that their study proves that metallic water can be produced here on Earth, and that their study “characterises the spectroscopic properties associated with its beautiful golden metallic luster.”
Truly magnificent.
