Well, actually, more like soda into ice. Note that the soda bottle is unopened, and all liquid. Then I open the bottle and pour, but futile, since the soda has turned into icy slush! There's no trick photography. I actually don't know how this happens. This is slightly different than super-cooling effect, turning beer/water into ice.
I believe that the soda is near freezing point and that opening the bottle lowers the pressure quickly enough to tip it into freezing state. Notice that not all liquid turns into ice as it is with super-cooling effect.
Trying out the super-cooling effect would be nice, too. I should try that sometimes.
