| I noticed something interesting in my car today, I have a 32 pack of water in the backseat that I have not taken in yet for lack of room so it has been sitting in my car for a couple of weeks, also I have some loose bottles on my front passenger seat that I use at work, obviously with it being so cold lately (high of 18 degrees today, currently 10 degrees) the water is frozen. Most of it is anyway, that is the wierd part, some of the bottles, seemingly at random, in both the unopened pack and on my seat are completely unfrozen while all the other bottles are frozen solid with not a hint of thawing, why is that? Why are some of the bottles completely unfrozen, while all surrounding bottles are frozen solid and all of the bottles have been undisturbed in the same car for the same amount of time and in well below freezing conditions? |

Super cooled?

| Bottled water is filtered and therefore not enough impurities in it for the ice crystals to form on. Â If you put an unopened bottle of water in the freezer carefully with no air bubbles in it, it won't freeze. Â But the minute you shake it and make bubbles it allows the ice crystals to form and freezes solid. Â |

My son; if you knew only a fraction of what I know about the physical universe; you would lock yourself in your closet, cover yourself with blankets, drink 'til you were blind, and beg for your mommy. You just have no clue. |

You just have no clue. Thats pretty much my plan for 2017, regardless of what you know or how water freezes... |

Video the bottle as you shake it and show us the ice forming. |

You just have no clue. Ice is an insulator- the outer bottles have insulated the inner ones. eskimo snow cave for example. |

Are the unfrozen bottles over something that would generate heat while driving, drive shaft, trans, rear or transfer case? I had a similar situation bottle in cup holder not frozen, but one in back seat was solid. Then realized bottle in cup holder was over transfer case, just enough heat to prevent freezing. |

Bottled water sometimes has a high concentration of bacteria, some bottles more than others.
These bottles are the ones not freezing as their microbal actions help heat the water.

Pressure variation in the bottles would explain it. |

No, the water in the backseat is on top of the seat, and so are the bottles up front. Also, the unfrozen bottles in the pack in the back are on the outside layer of the pack as well so it is not insulating from the other bottles. I'll try shaking them when I get back to my car. |
