Tap the bottle gently with your knuckles, and you will see the water in the bottle freeze quickly! Watching a bottle of transparent water turn into translucent ice almost instantly is almost like magic.
3. Because the so-called pure water can't be completely pure, just because there are few condensation nuclei in it doesn't mean that it will never freeze. If the temperature drops further, it will freeze, and if the outside world gives it a disturbance, such as knocking at the door, it will freeze, so be very careful when you take the water bottle out of the refrigerator.
Put some ice cubes in the bowl and slowly pour cold water on it to get fast-growing ice bamboo shoots.
1. The principle is: the concept of supercooled water: scientifically defined, the liquid whose temperature is lower than freezing point but still does not solidify or crystallize is called supercooled water.
2. The supercooled liquid is unstable. As long as a little crystal of this substance is put into it or shaken quickly, it can induce crystallization and raise the temperature of supercooled liquid to freezing point.
