Water freezing?

  1. Jun 20, 2008 #1

    I for the life of me cant remember the explination to this...I remember learning it in High school but now Im just drawing a blank.

    When I put a bottle of water in the freezer and let it sit for a long time, it doesnt freeze.

    When I pull out the bottle it is clearly 100% still liquid. But, If I give it a shake, BAM! Instant Ice.

    I remember something about the water molecules getting in place, but under some condition they dont freeze but still get colder and colder...but if something moves them they will instantly freeze. Not sure if this is right.

    I dont know, but this has been happening to me for a few days now and I just want to know why. Cant seem to find it on the internet anywhere!

    You can find videos on youtube about this. As mgb_phys said, it's "supercooling"
