You’ve seen how scientists went looking for Earth’s oldest ice, now check out a new type of medium-density amorphous ice with the same density as liquid water. Scientists at the University College London started by putting regular ice into a tumbler with steel ball bearings cooled to -328°F, and the shear forces generated by the movement created this new medium-density amorphous ice (MDA).
The force from the metal balls basically transformed the ice into a white powder. Scientists then shot X-rays at the powder to determine how they were arranged. When the X-rays scattered, they discovered that the ice had zero organizational structure. They used a computer simulation to demonstrate how these randomly sliding layers of ice could make the structure become amorphous.

We have shown it is possible to create what looks like a stop-motion kind of water. This is an unexpected and quite amazing finding,” said Andrea Sella (UCL Chemistry), Co-author of the study.
