Insant freeze water

[hivoltagesledhead]

We have all seen the youtube videos of how to freeze water instantly, but something interesting happened to me yesterday. My co worker and I were working at around 2000' above sea level. I had a bottle of water in the cab, in my lunch box that I had opened in the morning and added 3 squirts of MIO fruit punch too. We drove up to the top of Dragon Mtn...maybe 3000' at best. The temp was -12. We finished our day and went back to our motel. When I got in my room, I put the bottle in the freezer for about 30 mins, I opened the unfrozen bottle of water, which showed signs of altitude change(the bottle was decompressed a little) and it froze instantly !!!

The water was in the cab of the truck all day, never reaching temps below 0.

This is not how its done on youtube.

Can someone explain the science behind this phenomena?

As in boiling the same goes for freezing. Boiling point changes when the pressure is raised or lowered. Same goes for freezing. The second you opened the bottle the pressure inside the bottle changed and changed the freezing point. At least that's how I remember it from science class 40 years ago

I don't know.....

I've been told that if you leave your bottled beer in the truck at 0° over night..it may not have frozen yet.

But as soon as you open it up...it turns to slush.

I have not tried this, but was warned about it after leaving beer bottles in my truck a couple weeks ago.

Pressure change must have something to do with it.

Because of the alcohol, beer has a lower freezing point than water. Add the fact that a beer bottle is pressurized do to the release of the CO2 gas that gives it it's carbonation, the pressure also lowers the freezing point. Open the 0 degree beer and you instataneously raise the freezing point causing it to slush up or make a ball of ice in the bottle. Pop is the same way.

I have noticed it with bottled water and coke all so. another thing we do is make ice with salt water in the summer, take pop from fridge and put both in a cooler and it will actually freeze your op

I assumed it had something to do with altitude change and the decompression in the bottle.....either way, it made for a neat surprise and dinner conversation.

Is it too early for a frosty beer?

Never too early!
