Get in the queue smart arses - I have a magic freezer!

[Mom]

Even the most simple of us know that liquids expand when they are frozen. In my experience water contracts when it freezes :yes:

How many of us have forgotten a bottle of something in the freezer for a quick chill, and found the countainer exploded in the freezer? In my freezer it gets smaller.

I drink water through the day. I wont drink the stuff that passes for water in Albany :sick: I wont spend money, buying something I already pay for at home. It pretends to be water, and I filter it to exclude the chlorine and aluminium that it contains.

I freeze my filtered water in a bottle at home and take it to work to drink.

So, I half fill a 1.5l bottle with filtered water and I screw the lid on the bottle. I place it in the freezer, on its side so it freezes by morning. The bottle is "normal" bottle shape when it goes in, and quite distorted when I take it out. "Flat" springs to mind. I top it up with filtered water, and by the time I get to work and want a sip of refreshing water, the bottle makes a distinct intake of air sound and regains its "normal" appearance when I open it.

Please explain!

Water does expand,
Thats why ice doesnt sink.. It's density is less than the liquid water around it.

[bogan]

Water expands a little, air contracts a lot more = smaller

[DrunkenMistake]

If I remember right, between 4 degrees and 0 degrees water contracts but below 0 it expands, by 9%

bottle on side in freezer, half full of water, sealed, yes?

as water freezes it expands, as it expands it compresses the air above it and as it expands it distorts the shape of the bottle. when you open the bottle the pressurised air comes out. You top it up and the laws of thermodynamics being what they are, the ice melts. the melting ice turns to water which shrinks. if there is an air gap the air pressure would decrease as the water volume decreased, if no air gap the bottle shape will distort, perhaps not so much you can see it. either way, when you open the top, the pressure equalises air comes in to fill the void, and thats the noise you hear.

or its the gnomes in your carbs getting thirsty. thats probably more likely. one or the other

not only have you frozen the water but you have also frozen the gas in the remaining half of the bottle and the plastic of the bottle. On its way to frozen the water does contract, as it turns to ice it expands. The contracting water, gas and plastic squash the bottle. The plastic freezes in this shape, it therefore remains squashed as you top it up with water and the frozen air escapes. When you open it at work the plastic defrosted, so has some of the ice therefore when you open it the plastic is going ot 'bounce' back to shape sucking in air.
How's that for a guess.

Id say its the Gnomes.

[Clockwork]

I think its the air inside the bottle that has contracted.... not so much the water.

[Headbanger]

So, your magic freezer......freezes water.

Awesome.


Though I think most of them do that.




If I had a magic freezer I'd want it to be full of unlimited steak and cheese pies, and they would be served up hot and tender, and it wouldn't need electricity, and it would fit in my pocket.

And I'd get $10 for each pie I ate.

Fuck yeah, thats a magic freezer worth owning.

[crystalball]

I am thirsty now.:yes:

[Hitcher]

If you think that your filter is removing the chlorine from tap water, it must be a helluva good filter. Many water filters sold in New Zealand come from Dodgy Brothers Ltd and are sold by homeopaths or similar flat earthers.

Chlorine is added for good reason: it's a disinfectant. You can only smell it when it's disinfecting. I'm not sure where the aluminium you think is in there has come from.

That said, I am fascinated by what's happening to your imploding bottles in your freezer.

Ah, No. Exactly the opposite.

When a liquid reduces to a solid, the molecules slow down and form a crystalline structure. Solids are always smaller versions of their liquid form.

Except water. It has the remarkable ability to expand. http://www.iapws.org/faq1/freeze.htm

You think that's water you are drinking?

[BMWST?]

water is at it most dense state at 4 c,as it actually freezes it forms an open crystaline structure.

[ducatilover]

Evil spirits I tells ya!

[Oblivion]

The only molecular structure more interesting than water is cheese. :yes:

[Bikemad]

i started drinking beer coz of evil spirits..........

Bottled water has to meet the NZ food safety standards
your tap water has to meet the NZ Drinking water standards which is much stricter.

Filtering the water won't remove the chlorine.
The chlorine disinfects and the remaining residual chlorine stops regrowth in the water and is healthier than the the alternatives like giardia.
If you shake the crap out of the bottle you should remove most of the chlorine as it turns to gas in aerated water.

Albany water comes from the Hunas and Waitakeres like the rest of Auckland.
Its last in the queue besides Whangaparaoa so the chlorine there is the lowest by the time it gets there.
Water from there is pretty good, and with the history of industry upstream of Warkworths plant I'd trust it more. Both are good though :)

Alum is the most abundant metal on earth and is 'naturally' in all natural water sources.
It reacts with the organics to make them all stick together and drop out of the water before its further treated and sent to you to drink.

If you want to improve the taste of your water then get a water bottle with an activated carbon filter on it. That'l mop up any remaining organics in the water.

Try placing the water bottle in the freezer in a way that lets leave the lid on loose.
Then the air in the bottle cant suck the walls in when it contracts from getting colder.

Good luck. :)

I'm not sure where the aluminium you think is in there has come from.

I know, amazing shrinking water bottle, how smart arsed are some of these replies!

I went on a school trip to the water treatment plant here in Warkworth. Our water is taken directly from the good old Mahurangi River, full of cow shit and agricultural run off. It also contains mud, sticks, dead animals, that sort of stuff. They pump it up out of the river and run it over a sand and stone filtering area to remove all the BIG bits, then they dose it with a liberal amount of aluminium sulphate (like in your deoderants, linked to alzheimers). It is a flocculating agent. It gathers up all the disolved solids and drops them to the bottom of the tank, the "clean" water then runs out the top to another pond where they bomb it with chlorine. At least we dont have fluoride in our water :dodge:

At best it is swimming pool water that will aggravate my already fading ability to remember shit :shutup:

I can notice a big difference in the taste of the water if it does not come out of the filter, so for me it is doing "something".


If you shake the crap out of the bottle you should remove most of the chlorine as it turns to gas in aerated water.

Good luck. :)

HA HA! You sir are a friggen genius!

When you put the sealed bottle in the freezer the air in it is at room temperature . The hotter the air the more the molecules vibrate and the bigger space each molecule needs. This causes the air to expand and its density to fall.
As air cools, the vibrations slow down and the molecules need less room. This causes the air to contract and its density will go up. Thus the pressure of the air in the freezer takes up the available space vacated by the air in the bottle.

On opening and warming the pressure equalises and the squished bottle returns to normal.

Try putting the half filled bottle in the freezer with no top on, I guarantee it will maintain its shape.

That said.... It is still kind of magic.

A brilliant and most excellent experiment.... If you can lay your hands on an old gallon size metal oil can with a screw top lid. Fill it to about quarter full with water, heat on hob until water boils for a couple of minutes (with lid off), replace lid tightly and remove can to a safe place.

The air in the can is replaced with steam so on cooling the steam condenses back to water and leaves a partial vacuum in it's wake. Even though air pressure at sea level is only 15ish Lbs per sq inch, it takes great exception to vacuums (partial or otherwise) an it will unleash its almighty vengeance on the can. Seriously, the can will crumple with the force and noise of ten invisible sledge hammers.

If preformed covertly with an an unsuspecting audience it can prove to be a titillating jape of the highest order. Those of a nervous disposition may evacuate unpleasantness however.

What will taking her top off, before putting the bottle in the freezer do about the shape...? :blink:

Drink Red Bull instead.

Fascinating stuff water, a couple of things I remember from an old book, (Oldtimers is kicking in here too). You cannot compress it, if ice sank then the planet would be a snowball. All of the water on the planet came from space, we have exactly the same amount now that was here billions of years ago. I guess you could say we all drink wee.

Yeah/Nah. Neither is any better than the other.
Turbidity sensors can be masked. The drinking water standards in NZ are a bit funny. They check the data but never the application.

Its kinda like checking OSH by looking at the notebook in the first aid kit.

Or a building by looking at the drawings.

"Fudged" comes to mind. But thankfully nothing really happens and no one gets sick.

I loved that experiment in 5th form Chemistry. Good times :woohoo:

Hell, they even taught us how to make napalm at school :killingme:
