William Phillips discovered supercooling in Pennsylvania
Water that stays liquid at temperatures below freezing is called supercooled water. This phenomenon occurs when the water is kept in a very pure state and is cooled slowly below its freezing point without forming ice crystals.
To create a supercooled solution using ice water and salt, you can mix salt into the ice water to lower its freezing point. This will allow the solution to become supercooled, meaning it remains in a liquid state below its normal freezing point.
This is a supercooled water.
In order for water to be supercooled, there must not be impurities that can act as nucleation sites within the water. Spring water should work, though tap water would more than likely need to be purified before it would be supercooled, as by reverse osmosis.
The vapor pressure of supercooled water is higher than that of ice at the same temperature due to the increased mobility of water molecules in the liquid state compared to the solid state. As a result, supercooled water is more likely to evaporate and exert a higher vapor pressure than ice.
He invented the Wilson cloud chamber. It uses supercooled water or alcohol vapor to make the paths of subatomic particles visible.

Water vapor can exist at this temperature if it is supercooled (if there is no condensation nuclei for it to form on).
He invented the cloud chamber (also known by the name Wilson chamber). Cloud chambers use supercooled water or alcohol to track the paths of subatomic particles.
