Supercooling
Have you ever seen water that starts to freeze when poured or vibrated?
Such water is in a state called "supercooling."
Water usually freezes at 0 degrees Celsius, but if you lower the water's temperature very slowly, it can remain liquid even below 0 degrees. This state is "supercooling."
If you apply vibrations or other stimuli to water in a supercooled state, you can observe an interesting phenomenon: it starts to freeze rapidly.
Incidentally, oolong tea chilled in my room's refrigerator sometimes starts to freeze as I pour it into a glass, making it difficult to drink.
The temperature in the refrigerator might be too low.

過冷却
注いだり振動を与えると途端に凍り始める水を見たことはありますか？
そのような水は、「過冷却」の状態にあります。
水は本来0℃で凍りますが、とてもゆっくりと温度を下げていくと、0℃未満でも液体の状態になることがあり、この状態を「過冷却」と呼びます。
過冷却の状態にある水に振動などを加えると、急速に凍り始める面白い現象を観察することができます。
私の部屋の冷蔵庫で冷やした烏龍茶は、注ぐと凍り始めることがあり、なかなか飲むことができません。
冷蔵庫の温度が低すぎるのかもしれません。
