In a soothing experiment, scientists converted purified water into metal and conducted electricity through the liquid for a few seconds.
Unfiltered water already contains salt, so unfiltered water can already conduct electricity. In other words, negatively charged electrons can easily flow between molecules. According to the statement About new research. However, purified water contains only water molecules, the outermost electrons of which remain bound to the specified ones. atom, Therefore, they cannot flow freely in the water.
Theoretically, when enough pressure is applied to pure water, the water molecules are crushed together and the valence shell, which is the outermost ring of electrons surrounding each atom, overlaps. This allows electrons to flow freely between each molecule, technically turning water into a metal.

The problem is that crushing water into this metallic state requires a pressure of 15 million atmospheres (about 220 million psi). Research author Pavel Jungwirth, a physical chemist at the Czech Academy of Sciences in Prague, said: Nature News & Comments.. For this reason, geophysicists suspect that such water-turned metals may be present in the core of giant planets such as: Jupiter, Neptune When Uranus, According to Nature News.
However, Jungwirth and his colleagues wondered if water could be converted to metal in a variety of ways without creating the ridiculous pressure found in Jupiter’s core.They decided to use alkali metals containing the following elements: sodium When potassium Holds valence electrons in only one electron. Alkali metals tend to “donate” this electron to other atoms as they form chemical bonds. This is because the alkali metal becomes more stable when its only electron is “lost”.
Alkali metals can explode when exposed to water, and Jungwirth and his colleagues say they have actually studied these dramatic reactions in the past. Cosmos Magazine.. However, they theorized that if they could somehow avoid the explosion, they could borrow electrons from alkali metals and use those electrons to turn water into metals.
Their new experiment is featured in a report published in the journal on Wednesday (July 28). Nature, The team did just that. In the experiment, a syringe filled with sodium and potassium was placed in a vacuum chamber, a small droplet of metal that was liquid at room temperature was squeezed out, and then the metal droplet was exposed to a small amount of water vapor. Water formed a 0.000003 inch (0.1 micrometer) film on the surface of the metal droplets, and soon electrons from the metal began to plunge into the water.
For the experiment to work, the electrons had to move faster than the explosion reaction took place, Jungworth told Nature News. And when the electrons zoomed from alkali metal to water, something incredible happened. For a while, the water turned a shiny golden color. The team was able to use spectroscopy to show that the bright yellow water is actually a metal.
“Our research not only shows that metallic water is actually produced on Earth, but also characterizes the spectroscopic properties associated with its beautiful golden metallic luster,” Berlin said. Research author Robert Saidel, who is responsible for the group of young researchers at Humboldt University, said. statement. “You can see the phase transition to metallic water with the naked eye,” he added.
“It was amazing, [when] Discover new elements. “
