that happened to me in egypt, its not to do with the outside temperature, its to do with pressure change and the transition between temperatures.

The solubility of a solute in a solution is directly related to the temperature of the solvent. Example: at room temperature, there is a maximum amount of salt molecules that can be dissolved in a given mass of water. You boil the water, the maximum rises. You add salt to reach the new maximum, then cool the water back down. It is now a supersaturated solution. The addition of a single salt crystal will cause the supersaturated salt in the water to come out of solution and recrystallize. Tadaaa!

This is simply supercooling. Looks spectacular, pretty standard high school physics though :)

I thought this was supercooling. The bottle was left outside in the below-zero temperatures. This cooled the liquid, but as it was at rest it did not change state. In opening the bottle, he agitated the molecules causing a chain reaction, resulting in the change of state. This is supercooling, but liquids can also be superheated. e.g. people warm cups of coffee in microwaves, increasing the temp. past boiling point, but as the coffee is at rest it doesn't become a gas. Upon movement, it explodes

i was happy listneing to rock and roll howd i get here -_- ?

this just happened to me just now, i opened a bottle of water from my freezer to make it cold, it was a liquid state, then i shooked it by accident and all of a sudden it froze, i was like wtf! NO!! now i have to wait until it melts a little bit

That's sodium acetate, yes?

@acernegundo you sir are a genius

[fyrdawg589]

that is stupid cold

[noura20]

it just happened to me this morning. This happens when the temperature outside is not called enough to freeze the closed bottle as the there is no place for the the pressure to go. so as soon as you open the bottle the pressure is suddenly equal to the atmospheric one and it's called enough to be in ice state. However, if it is really cold, your bottle will just burst and the water will freeze even under pressure!
