GoldStarelete -- 04-Jul-2011 09:20:54 pm -- To blak406.. You are thinking of thermodynamics, just a heads up Pressure and Temperature are related, water that we know of is not at its pure state, it freezes at 0 or 32 and boils at 100 or 212 AT ATMOSPHERIC PRESSURE 14.7 PSIA, It can remain in a fluid state down to its homogeneous nucleation point of approximately −42 °C, ALSO water expands when it freezes and expands when it boils, It has to to with relative density, it is an odd but you cant think like your on earth all the time you have to open your mind to reality and that is being able to manipulate your mind to think about something realistically and not being biased to the fact that some molecular structures only act one way but really its to your default because you have only ever seem them act this way.
why would the water expand dumb ass??? when water molecules freeze they slow down from a fast state of motion to one that is almost motionless. water makes glass shatter when you take it from a cold to extremely hot environment all of a sudden. the water is distilled and super cooled which means that the water is colder than freezing temperature, but not able to freeze due to the lack of oxygen required to freeze. when he touched the ice it was cold enough causing the water to freeze. all real
It's some chemical in the water. I think it's an exothermic reaction and it is not cold. I forget what it is but it creates a gel but it is not cold. Look up: How to make Hot Ice!!! Crazy on youtube and see how it works.
Apart from that, what is inside the bottle is certainly not dry ice. Dry ice is in fact the solid state of CO2 (carbon dioxide) gas, it is not related to any kind of H2O.
If dry ice is inside the bottle, you would certainly see white fume (CO2 gas) coming out from the bottle. As solid CO2 would quickly changes to liquid then gas under room temperature and pressure.
Unfortunaely i didn't notice that there is words limit. To explain why water freezes when there is sudden drop of temperature or impact, why don't we make clear how does this work. The key to achieve this is to SLOWLY cool the water. By doing this, water may not freeze at low temperature. When the water touches colder thing or rough surface such as gas bubbles, the water would freeze itself. You could certainly try this without using freezer. As freezer cools water too fast.
well, one more thing to prove this is water, is that you could see water vapour condensed on the outter surface of the bottle. This is caused by cold inside, hot outside effect (just like when you take out a can of coke from freezer). Water moisture at hotter atmosphere would condenses on colder surface because of loss of internal energy.
If inside the bottle is a saturated solution, such as sat. sodium accitate solution(so-called hot ice), the bottle would be dam hot. (what do i mean dam is really dam! lol) Well, this exothermic chemical is now generally used by people when in winter, as warm bag.
Yes, H2O could do this, but i'm afraid i don't agree it was because of pressure changes. In fact, water has the strangest reaction towards change of pressure. At rpt, water is at liquid state, but different from other liquids, when pressure of ice increases, the H2O molecules pack towards each other and become as dense as at liquid state. At certain high pressure, water at -50 degree-celsius could even turns from ice to water. Tom's thought of "pressure change" could not be applied in this vedio, as opening the bottle already instantly decreases water's surrounding pressure. Water in Tom's case should changes into ice once the bottle was opened. Besides, to remind that changing surrounding pressure would not affect the bp and mp of one chemical, but only the packing density between molecules, which could eventually changes the chemical's physical state.

It is ice guys. I've seen many other drinks do this. You take a beverage, such as beer and put it in the freezer until you know the beer is cold but not frozen yet. Now open it and try pouring it out. Presto! It does this because the pressure the drink is under is changing, causing the freeze. Increasing the pressure of a container does have a direct impact on freezing point/boiling points. It's not chemistry--it's physics!
