Just don't let water crystalise when it's below 0°C and that's the type of results you'll get.

Wow, that was way cool.http://www.youtube.com/watch?v=fSPzMva9_CE

So how do you prevent it from doing that? Id love to try it at home.
What happens if you drop a temperature probe into supercooled water?
Is the freezing process exothermic or endothermic?
Freezing releases heat. If it absorbed heat, it would solidify completely once it started. Instead what happens is that some of the water crystallizes until the temperature of the water/ice mixture reaches the freezing point.What happens if you drop a temperature probe into supercooled water?

I notice that the resulting ice is quite "slushy" in nature.
Peace.
It won't be any colder than water with ice cubes in it.Wouldn't that give them a brain freeze? I don't think it would be safe to drink crystallised water.
If you manage to drink it without the ice forming it will, and even if the ice forms in your mouth (and the temperature goes up to 0ºC) it will chill you more than drinking ice water.It won't be any colder than water with ice cubes in it.
I don't see why. The freezing process releases heat.If you manage to drink it without the ice forming it will, and even if the ice forms in your mouth (and the temperature goes up to 0ºC) it will chill you more than drinking ice water.

Ah, yeah, that's true. A bit more than ice water, then, but less than, say, a snow cone. Not really anything to worry about, I should think.Yes, but you'll get the ice slush in your mouth. And as your body melts that, heat must be transfered from your body to the slush. 0ºC ice will chill you more than 0ºC water, since there's more energy needed to raise it to body temperature.
To be more exact. When I'm talking about drinking ice water, I'm talking about a glass of water with ice cubes in it. And you only drink the 0ºC water, the ice cubes stays in the glass.

That's not the case at all. To freeze, it must have a site on which to start the crystallization process. Opening the bottle doesn't create a site for the crystals to start to form.Maybe it was already said, but no, that's not right.
If that was supercooled water (meaning it wasn't allowed to crystalize below 0C), it would freeze the instant you open the bottle, which doesn't happen here.
This happens if the water is under pressure. Essentially, in a higher-pressure environment, ice cannot form. Opening the cap releases the pressure. The existence of enough air in the bottle prevents the pressure from building up so much that ice can't form.Anyone can try this at home, take a bottle, fill it up with water so it's REALLY 100% full, seal it and put it to freezer, it will stay liquid 'till you open the bottle.
