Principle of freezing of supercooled water:

Supercooled liquids are unstable, and as soon as a small amount of crystals of the substance is put in, crystallization is induced and the temperature of the supercooled liquid rises back up to the freezing point. This unstable state, which can be quickly transformed by a small perturbation, is called a substable state.

How to make supercooled water:

To make supercooled water, you need to prepare distilled water, beverage bottles (preferably glass), refrigerator, towels, beverage bottles must be clean, if you can not grasp the temperature can also prepare a thermometer. It's very easy to make cold water, just two steps are needed, the principle of cold water formation is wonderful but very simple.

Pour distilled water into a bottle and place it in the freezer. The bottle must ensure that clean, and to ensure that the bottle is stored vertically, do not shake, put in the refrigerator about 2-3 hours, be sure to pay attention to the time and temperature, if the temperature is not good to control the temperature of the bottle wrapped up in a towel, will be placed in the middle of the bottle and the towel, pay attention to the temperature of the observation, to the 0 ℃ on it. This step is the temperature is not high control, try a few more times on the line.

To 0 ℃ on the take out, the water slowly pour out will see the water instantly frozen. The water out of the time must pay attention to do not shake, gently pour out a little, you will see the water instantly frozen, especially nice and marvelous. If you fail, do not be discouraged, try a few more times on the line, be sure to pay attention to master the temperature, you can also bring the failed product to continue to use, will not be wasted, and also has no effect. It is best to adjust the temperature of the refrigerator to minus 7 degrees Celsius, record the time and temperature, try a few more times certainly can.
