Supercooling or 'surfusion' or allow freezing water instantly.
Transform water into ice instantly through supercooling, this is a metastable state. A material that remains in liquid form below its solidification temperature.
We all have taught us that the water turns to ice below 0 ° C, if one is at normal atmospheric pressure.
It is possible to have liquid water with temperatures below zero, without affecting the pressure.
Curious, but not that hard to visualize.
Take a bottle of soda and to freeze on command! This trick "super cool" works with all sodas.
A state where the material that is in liquid phase passes its solidification point. Freezing reaction does not fire below 0 ° C spontaneously, when you have a disturbance: a vibration, shock, dirt ...
To conduct this experiment you will need:
- A bottle of water or soda - never open
- a freezer
Researchers have managed to get water at temperatures as low as -39 ° C without freezing. The supercooled water will freeze as soon as it comes into contact with a solid surface or a particular type of aerosol called freezing nucleus.

WARNING:
Do not leave bottles in the freezer too long, this can cause breakage of the container. Glass bottles are not recommended because ice expands during freezing and can break the glass.

To achieve this effect, I put 4 bottles of 500 ml soda in a freezer at -18ºC between 2:30 to 3:00 hours.
Each freezer has a different temperature, and I noticed that the location of your bottles in the freezer makes a huge difference to the freezing weather. For best results, choose a consistent place in your freezer, and play with gel times to see what works best for you. My freezer, the middle of the center rack stabilizes at -18ºC (-11ºF) and takes 2:45
To play with soda outside the bottle, remove the pressure slowly, this will keep the liquid soda and give you the option of choice with soda supercooled to outside of the bottle.
