When properly manipulated, though, liquid water can also freeze in a disorganized, amorphous state. The first of these states, low-density amorphous ice, was discovered in the 1930s.

Scientists created a weird new type of ice that is almost exactly as dense as water. News. ... The first of these states, low-density amorphous ice, was discovered in the 1930s.

The density, however, did not match the already known high- and low-density amorphous ices. Intriguingly, it fell in between; indeed, it was almost exactly the same density as liquid water.

To find the loosely structured, Goldilocks-density ice, the team shook ordinary water ice in a jar crammed with steel balls, cooled to about -376 degrees Fahrenheit (-200 Celsius.) ...

Amorphous ice was first discovered in its low-density form in the 1930s when scientists condensed water vapour on a metal surface cooled to -110 degrees Centigrade.

Researchers have created a never-before-seen form of ice with a disorganized structure and a density almost exactly that of liquid water.
