You’ve seen how scientists went on the lookout for Earth’s oldest ice, now take a look at a brand new kind of medium-density amorphous ice with the identical density as liquid water. Scientists on the College Faculty London began by placing common ice into a pitcher with metal ball bearings cooled to -328°F, and the shear forces generated by the motion created this new medium-density amorphous ice (MDA).
The pressure from the metallic balls mainly remodeled the ice right into a white powder. Scientists then shot X-rays on the powder to find out how they had been organized. When the X-rays scattered, they found that the ice had zero organizational construction. They used a pc simulation to exhibit how these randomly sliding layers of ice might make the construction grow to be amorphous.
