This one is for Acebird

[Jim 134]

Your science lesson for today.
I am sending this to my very smart friends knowing someone will provide an answer...!
Frozen Water Bottle
Molecular Levels
Okay, you engineers, scientists and smart ones out there, explain this one!
The frozen water bottle.
Folks, this is really interesting.
Don't know why this happens.....Do you??

Crystallization requires a catalyst under conditions of zero motion. I've had the exact same thing happen until I shook the bottle and it froze instantly.

Seams as though banging around in a trunk would create motion though.

The man says "truck", not trunk.

Jim's just messing with us. When water gets cold, it freezes.

[JRG13]

It won't if not disturbed under the right conditions. My dad has seen lakes calm as glass freeze over instantly when a gust of wind finally caused rippling, and I've seen the same thing with a bottle of water in a freezer, it was still liquid when I picked it up but as soon as I swirled it, it froze instantly. I remember it being talked about in chemistry as well. You need a minor input of energy (in this case movement) to initiate solidification.

and it's always true on youtube

Yeah, right. I'd like to see him do that w/out turning it up side down. Bet it wouldn't work. Just because it got cloudy doesn't mean it was frozen. Bang it on something to show me it's frozen and then I will believe it.

I used to do this all the time at work, I would put a bottle of water in the freezer when I got there, several hours later it would still be clear liquid, when I opened it and took a sip I would get one mouthfull of very cold water and then I would watch the ice level starting at the top and go down to the bottom, leaving a botle of firm slush.

The trick is it has to be undisturbed and very pure as it cools. He didn't have to turn it upside down, he could have flicked it on the side, but it is more impressive going top to bottom.

beecurious is right

It's called Science...

Look up nucleation and supercooling.

I think it's so funny that Beesource's resident ace engineer believes that the two videos are staged.

A lot of folks don't trouble themselves to learn about things.

A similar phenomonum can be observed at the other end of the temperature spectrum. A cup of tap water and a cup of distilled water are put in a microwave and heated until the tap water is boiling. Distilled water appears still until something (spoon, sugar cube) is put in it. Stand clear, sometimes it splashes violently.

Saftey tip, heat water in a vessel with a wide open top (such as a bowl) if you heat it in something with a narrow top it acts like a nozzel when the violent splashing begins.

I don't claim to be an engineer, so excuse me, but, what does this have to do w/ engineering? Brian never claimed to be a scientist.

It's physics...
