Another query about water/ice

[SNOWBALL]

Girl (6:58:25 PM): So, I keep my water in the freezer, right? In the door of it so that it get REALLY cold, but it never freezes
Girl (6:58:46 PM): and when I take it out of the freezer I ALWAYS look and I can see that it is all melty still
Girl (6:58:51 PM): perfect for drinking!
Snowball (6:59:00 PM): yar
Girl (6:59:04 PM): But when I open it and my breath touches it
Girl (6:59:11 PM): it turns to slush!
Girl (6:59:16 PM): all thick like
Girl (6:59:23 PM): all the way through
Girl (6:59:30 PM): so there's only a few drops of liquid!
Girl (6:59:44 PM): I've never seen water get like tht before
Snowball (7:00:04 PM): you put it in when it's full?
Girl (7:00:01 PM): when water mostly freezes it's usually all jagged and sparce
Snowball (7:00:15 PM): a full bottle?
Girl (7:00:20 PM): but this is like...slushee style
Girl (7:00:47 PM): it's usually pretty full. Maybe half an inch below the spout
Snowball (7:01:11 PM): so you think you actually SEE it transform when you open it?
Girl (7:01:46 PM): YES
Snowball (7:01:56 PM): ok this should be interesting

I used to be able to time how long to leave a glass bottle of Pepsi in the freezer so that when I opened it the pressure in the bottle would decrease and it would turn to slush. My guess is that if she left the water in the freezer with the lid off it would freeze solid.

YouTube video that is cool to watch: Supercooled Water

I once observed a 5-gallon plastic jug with distilled water in it become supercooled overnight in a trailer (it was only 2/3 full). It was left on a bottom shelf during the winter and cooled all night (must have got to 20 F). When I came back in the morning I noted that the water was still liquid; I then gently kicked the container and in a few seconds the water froze solid with an interesting soft crackling sound. Quite cool I thought - Crystal nucleation by a kick.

Here’ s your conversation:

and when I take it out of the freezer I ALWAYS look and I can see that it is all melty still
Girl (6:58:51 PM): perfect for drinking!
Snowball (6:59:00 PM): yar
Girl (6:59:04 PM): But when I open it and my breath touches it

Girl (6:59:16 PM): all thick like
Girl (6:59:23 PM): all the way through


And here’s how Lewis Carroll ended your conversation in Jabberwocky:

"One, two! One, two! And through and through
The vorpal blade went snicker-snack!"

An uncanny resemblance.

Impress your lady friend. You're welcome.

i dont understand why hitting the bottle or stirring the water makes it freeze.

true/false: the water will remain liquid until a nucleus crystal is formed or introduced, at which point ice crystals will build off of that crystal and very soon your water has become a bunch of ice crystals (i.e., ice). if true, why does hitting or stirring the water form/introduce a crystal?



also, if the temperature in your freezer got below a certain point (i think like -42C), the supercooled liquid water would spontaneously form into all crystals (e.i., ice) without the need of a nucleus crystal, right?
