1.   This is crucial as the ice crystals formed when water freezes would destroy the egg tissues.

2.   First, salt lowers the temperature at which water freezes by interfering with the formation of ice crystals.

3.   Hailstones grow as tiny water drops freeze on contact.

4.   If pockets of air become trapped when water freezes, ice will likely have whitish markings that make it less transparent and more easily detectable.

5.   In the cold upper reaches of a thunderstorm, hailstones grow as tiny water drops freeze onto them.

6.   Rather, as long as spraying continues, heat is given off as water freezes, keeping ice and the encased buds warmer than the air.

7.   Trouble is, the water freezes, making it hazardous.

8.   While suspended high in the subfreezing upper parts of an intense thunderstorm, hailstones grow as tiny water drops freeze on contact.
