Supercooled water is two of a kind, a new study shows. Scientists have long suspected that water at subfreezing temperatures comes in two distinct varieties: a high-density liquid that appears at very ...

If you thought ice varieties got no more interesting than crushed versus cubed, think again: Researchers have discovered an ice form whose haphazard molecular structure resembles that of liquid water, ...

Supercooled water may be a two-for-one deal. A long-standing theory holds that liquid water at temperatures well below freezing is composed of two different arrangements of molecules, one with high ...

Compare the density of water to that of different liquids. Krystal Balmes and Sahil from the Brooklyn Preschool of Science make predictions about the density of water to that of honey, corn syrup, and ...

This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so you may want to try this outside. We're joined by BASF employee, Casey, and his ...
