Interesting thing that happens with water

Howdy.

Ok, i noticed this a little while ago. I put a soft drink bottle, regular 600ml variety on my kitchen tap. I forced it on so it was tight.
I then turned on the water and held the tap into the bottle, this made a airtight seal. Obviously the pressure built up quite a bit by the time it was around 3/4 full. I took it off, it came off quite easily and made sure it didnt hit the bottom of the sink so it wouldnt make a lound noise and big splash. You can see quite a bit of water vapour comes out of the top of the bottle, like fog or a cloud.

It comes out in whisps and its quite cool looking. I dont know exactly why it does it but its probably because of rapid compression and decompression of water and air. I could be completely wrong. Give it a go, the worst that could happen is a loud bang and a bit of a splash of water, if you are careful you can see this interesting thing.

So would i be right in thinking that the vapour thingy is appearing from the sudden decompression of air etc.?

Your probably getting 100%+ humidity (super saturated?) in the air in the bottle because of the pressure. When you release the pressrue suddenly the air is no longer compressed and cannot hold the excess water so it condenses out as a little mini cloud. Someone can probably explain this in partial pressures or something. I can't remember any gas law equations.

You get this when you take the cap off soda bottles as well.

Aspman hit it head on. Its because the air thats left in the bottle is constantly fuseing with water molecules as you fill it. Since the inside of the bottle is water and a lair of air, the h20 concentration is greater in the water layer than the air layer, obviously. Take what you know about concentrations, the fact that they always attempt to equalize, and you get the air layer becoming highly humid and vaporish, think fog. When you open the bottle to release it now there is a sudden HUGE difference in the h20 concentration and the fog rushes out in an attempt to better equalize the concentration of h20.

Better yet, get a 2 Liter of any carbonated soda, and then simultaneously drop 13+ Mentos (Original work best) into it. Very spectacular.

*NOTE: Do not do this inside, especially if you're ceiling clearance is less than 6-7 meters. You might also want to get the F*** out of the way once you drop them.

Howdy.

Thanks for the answers guys. ;) I did some more research on this both on google and with experiments at home. and this is just really fascinating for me..

I tried this outside and i got a somewhat spectacular result. i wasn't expecting for it to make the mess that i was left with though.

If you like doing neet little expirements here is one that i got a kick out of back in highschool chem.

Materials:
some electrical tape
4 conductive nails
a length of copper, or any conductive metal, wire
Pop bottle
Alchohol, if you use the drinking kind a higher proof works better.
corck that will fit in the bottle's mouth
Gum or clay
Dry-cell battery, the kind that you find in sproting goods stores that are big rectangluar and about 5-inches high and 2inches wide and deep roughly.

Take the bottle and lay it on its side. Take two of the nails and put them about half way into the bottle towards the bottom or it so that the tips of the nails almost touch. \ / kinda like that, then use the gum or clay to seal the hoels the nails made. take the other two nails and wrap some of the tape around it, enough for you to safely hold it, this is to prevent any sort of shock to you. Then take those nails and wrap a little wire around them and hook them up to the battery, one on each pole. this is your ignition. pour a little bit of the alchohol into the bottle and cap it. Wait a few minutes to let the alchohol begin to evaporate in the bottle. aim it away from anything you don't want broken, and take into account the bouncy factor of the cork, then touch the nails that are connected to the battery to the nails in the bottle. There will be a small spark between the two nail tips in the bottle igniteing the alchohol vapors and shooting your cork. If you dont get a good distance then just add a little more alchohol and try again. BE VERY CAREFUL not to add to much alchohol or the resulting explosion will be more powerful than the integrity of the bottle and instead of shooting the cork you will just blow up the bottle. My friends and i used to make these and go out back and see who could shoot the most cans on the fence, birds on the wire, or squirrels in the trees. Don't worry the accuracy of these things isn't that great so we never were able to actually hit any alive and moving targets, just the cans, although we did come close to a squirrel a few times, man can they jump. . .

DISCLAIMER
I take no responsability if you get hurt doing this, hurt someone else, or break something that wasn't supposed to get broken. This is a very simple and safe thing to do. If you are stupid enough to screw it up and get hurt its your own damn fault.

Disclaimer: I am bloody well not responsible for anyone being stupid enough to actually do this, or any injuries which might result if this is done improperly.

What you need:

A plastic bowl (a marjorine tub works nicely)

Drano

A piece of tinfoil, cut into 1/4 inch strips (about a foot of it).

A box of heavy duty garbage bags (the big green ones).

A roll of toilet paper and a cigarette lighter.

Do NOT do this on a windy day! For best results, do this on a calm night, far away from structures or trees.

Put about 2 inches of draino in the bottom of the bowl. Insert some strips of tinfoil. Wrap a garbage bag round the top of the bowl for as airtight a seal as you can get. After the garbage bag fills, tie it off, tie a long-ish strip of toilet paper to the garbage bag. The toilet paper is your fuse - light it on fire and release the bag into the air.

What you've done:
The tinfoil reacts with the drano to produce pure Hydrogen gas, which is lighter than air and quite explosive. The garbage bags trap the hydrogen and acts as a balloon, to which you've tied your toilet paper fuse. I'll leave the rest to your imagination, but the Hindenberg disaster gives a good indication of what happens...

BI forgot to add at the end after your experiment sit back and wait for the DHS to hand deliver your one way ticket to sunny Cuba.

Actually... If your water is chlorinated I think you'll find that the mist you see is chlorine being "blown off" because of the sudden change in pressure. If you fill a bucket with fresh water and get the light right you can see a mist coming off the surface. It's this "blowing off" of the chlorine that most marine aquarists use to get _fresh_ water for top-off... You can spend money on dechlorinators or just let the bucket sit for 12-24 hours and the chlorine will go away on it's own.

Man you guys suck. None of that gets you free pop. (Soda to you red necks.)

Me and my Best friend did this one night while being thirsty and broke:

We had been at Dennys Restaraunt for a couple hours, my best friend stole a bottle of salt.... Not sure why. So anyway, we decide, hey, a 2 litre in the back seat... There was a two litre bottle in my back seat and me and him were thirsty. So we went back to Dennys, made the bottle half full of water from the bathroom sink, went back in my car, saw an OLD coke machine by a motel, poured the salt into the half full bottle, and then emptied the whole thing into the machine's coin and paper dollar slots.

The effects were instant. Cans started POURING out of the thing. So we quenched our thisrt, loaded my trunk and drove away.

You guys are getting pretty technical. :P

Ill use BlackIce's Disclaimer

Disclaimer: I am bloody well not responsible for anyone being stupid enough to actually do this, or any injuries which might result if this is done improperly.

We always used to have fun with dry ice and water in those 3 liter soda bottles. Simple and effective and usually produces a nice bang. Dont use the 1 liter bottles though, they go off too fast. And get away, because plastic flying fast hurts.

i like that method gore... anarchist cookbook?
i have most of that thing printed out... :)

i like my slightly simplier way... bolt cutters... for some reason all the pop machines around here have heavy duty locks on them... cut that and there ya go.. no key needed... and then your not destroying property as much as teh salt water method.. just a lock... im sure that pop machine is pretty f***3d after that

not like i have ever tried this of course... :)
and i do not reccomend you do

Bolt cutters are noisey and a cop can see you using them. But salt water you just pour in and it looks like you're grabbing paid for drinks.... Pop....(Soda for you south of Ohio, Coke for you in Texas)...

The absolute best way to deal with that stupid pop machine is really easy, it works most times and you will never get caught...

Put a freaking dollar in it.... If you don't have the dollar... Oh well... You can't afford the pop... Live with it...

You've obviously never been on a 3 hour road trip, getting lost for 4 hours more, being thirsty as hell, and nothing to drink.

Gore:

1. I _DON'T_ get lost.... I have been reading maps at the contour level since I was 7. I can look at a map and _see_ the ground.... When I am 1000 miles away from it and never having been there before. So that is a silly argument where I am concerned.

2. I was trained to do _everything_ including forced marching 20 miles with 100 pounds of equipment on only 2 pints of water per day. Everything includes drinking, cooking, washing, shaving and first aid... That is a silly argument where I am concerned.

3. I was a Combat Survival and Rescue Instructor who came top of his class and top of all classes that had been through the school since it's inception. I supported, fed, heated and sheltered 15 other people while they tried to break us. They failed... :D That is a silly argument where I am concerned.

4. I got a job... That is a silly argument where I am concerned...

That's not a personal attack.... It's meant to prove that you _can_ do things you don't think can be done... That you don't need to abuse others to do it... Pay the dollar or find the alternative... There are _always_ alternatives... Trust me...

You want me to listen to you? Trust you? The first thing you ever said was NOT to trust you or anyone else lol.

Background info since you're being a cop today:

I was working 6 days a week at the time. Where was my money? I was driving in it.... It was break even for me. I worked and could drive to work, maybe buy smokes, but that was it. I couldn't afford anything extra for the hell of it.... I was thirsty, no money, but as I pointed out my best friend had stolen a salt shaker and there was an empty 2 litre bottle in my back seat.

Now that couple pints of water story is cute, it really is, but I've never been in the military, and my "training" stops at Karate. No school I've been to shows you how to survive a 120 degree summer day with nothing to drink, however surviving was taught. Do you honestly think Coca-Cola is going to come after me for a couple dollars in pop?

Dude, seriously, some day at least, just understand that there are people in the World who didn't join a military so they could get tortured by some jack ass that thinks you're EVER going to need to know how to live on a pint of water in the East coast of Michigan.

So, since there is ALWAYS an option... What were my Options ? None of us had money, or a bank account, it was 3 AM, and no where near home. The pop bottle was the only one so it wasn't like we could have taken those back for something to drink.... Oh I know! We could have robbed a store! Or even better hit an old lady with my car and stolen her purse! Oh oh oh or!!!! We could have risked being arrested and tried to steal some pop from a store!.... Dude seriously lol that is the ONE time I did that and I may regret stealing it but what would you have done that DOESN'T involve training that you have?

As for being lost, I didn't use a map. They aren't free and if I could have afforded a map I could have afforded a pop.

So... I guess you missed the whole point... :)

Never mind...

Intellect can solve any _basic_ problem without screwing someone else over... Yes, you improvised... That's good... But you improvised in a bad way...

It's actually not that difficult... You can even use your own pee to do it... or any vegitation you can find... or if you are _really_ in deep poop you can simply survive on the moisture available in the air at night... Really... it can be done... I used to teach it and had to practice it first so that I had some "authority" when I taught. There are tribes in the deserts of Africa that do this _every_ day to survive... You can do it anywhere in the USA... In Michigan it's a no brainer... You chose not to... That's fine... But when you do people wrong then you do yourself wrong.

I _prefer_ to do the right thing with emphasis on my intellect and knowledge... It's always worked for me... :p

I know how to harvest water from humidity. Anyone who's seen a window in summer should know how. It's hot humid and water is on the window.

And I wasn't aware you were making a point other than being able to post about how you soldered a network card together with a cigarette lighter for the good of humanity as a whole. ;)

And I didn't screw anyone over by taking out a pop machine. The owner of the machine calls coke, insurance pays for a new one, he gets an updated model free and a very rich company shells out about 0.001% of their dailey earnings.

By the way you've yet to have answered how I would have gone about getting a drink or what options were left. I mean I know humidty COULD work but 3 people on a summer night are not going to stop being thirtsy because filtered a tampon and drank it...

Who pays the insurance????

Think _hard_ before you answer.....

Whoever had owned it for 20 years. It was old as hell, if he has to pay something every month might as well let him finally use it... Insurance is a scam. Someone as old as you has to know this by now, you pay insurance for something that MAY happen and when it does they raise your rates.

Now where are those options you were speaking of?

from his post... i think Tiger Shark should be changed from Team Leader to a G.I. Joe..

whos with me?

TS- I would be interested in some of these technique if you want to shoot me a pm or IM. Or just list them.. I am always intrigued and love the outdoors so everything about it I try to practice on my annual camping trips..

Gore-
You answered your own question but lets start from the begining. I grew up in Grand Rapids and Jenison Michigan. Great state its where I got my love for camping... I cant recall ever coming across a 120 degree summer day. let alone at night which is when your pop incident took place. Now back to your point... you could have probably gotten free water from Denny's (water quenches thirst), could have gone home and gotten water, and as you stated you live on the East Coast of Michigan.. Correct me if I am wrong but there is a BIG ass lake there. Albeit probably not the cleanest thing in the world but it could be Lake Erie instead...

Just a couple of free options

It goes passed 100 degrees here in Summer. I pointed out multiple times I was no where near home. Dennys at the time charged for water. And before you say it, the sink was gross.

Seconed:

Tiger doesn't use IM.

gore you can go days without drinking water, if you were thirsty and had no money how about WAITING next time? And lets also remember that pop/coke/soda is one of the worst things to drink as a thirst quencher.

How the hell did this turn into tricks and things into gore is a criminal?

there are no criminals.. only a set idea of what is right and what is wrong

so what if you dont quite agree with that idea... you ARE human... and no human is perfect.

:)

gore: honestly i could care less about you stealing. what you do is your business as long as it doesn't affect me. You kept asking for other choices and i gave you the best one, waiting. Honestly though i find it very hard to believe that salt water will do that to a pop machine. Now i am not calling you a liar since i have not the technical knowledge of pop machines or one to try this on, yet, but it just doesn't seem to fit. Most pop machines have a ramp with holes in the bottom from small to big so as the coins roll down the chute they fall into the corresponding hole. Now salt water is an ionic compound and therefore will conduct electricity. HOWEVER the resistance in metal wires is much much less than that of saltwater, making it act more like a resistor than a conductor. This rules out the posability of you conneting contacts somewhere inside the machine fooling it into thinking you put in money. Now you also said that "cans started puring out". . . . this is highly suspect. Once the machine has enough money in it it waits for the button press to cycle the belts inside of it letting out one can at a time. Lets also remember that if you put in 1 dollar into a 50 cent pop machine, you dont get two pops you get one pop and change. This rules out the possablilty that you tricked the machine into thinking it had money in it also, for it would pause after each can and spit out change. Now that leaves about the only other possablility, that the water fried something in the machine causeing it to malfunction and spit them out. . . .sorry if taht happened you would only have gotten a can or two tops before the machine completly fried itself and shut down completely. Therefore i truly believe that you made this story up just to fit into the conversation.

OK, you know what I'm going to reply in about a half hour AFTER I CATCH UP with the 4 people currently jumping on me questioning me, what I do and why.

Got into it with Tiger Shark for 3 hours, got into it with another person overhow we ban people here, someone tellings me Gentoo didn't steal from Free BSD they were "inspired", and now you calling me a retard because I've been awake the last 4 nights in a row and miss read something while TRYING to type something that looked like ENglish.

To be honest I'm not even sure what the hell you just said. I saw you say you doubted I was telling the truth and got pissed off because I've made a point of being an honest person unless I'm bullshitting on purpose so it pissed me off for about 10 minutes before the next load of garbage came in asking me what..... I'm going outside.

Charged for water?? Man you were at a shitty Denny's. I too agree, I couldn't care less about you getting the pop I was just offering suggestions that were alternate to dousing the Pop machine with a super soaker full of salt water. I have heard of this method before from someone but have never tried it so i am intrigued to find out why it has to be salt water adn why normal water wouldnt work?

It wasn't a super soaker. It was a pop bottle. And yes this Dennys charges for water. Or at least they did when I was there at night. I was asking for water one night and when I went to leave they handed me a bill.

What's with all of the ethical issues? Sure, Gore was a punk and stole the soda. I've done that trick myself back in middle school when I was a little hellraising "fight-the-system" junkee. I wouln't condone it, nor do I condone it when I did it. It's a clever, but immoral thing to do. I'm not sure why this thread shifted to ethics of a neat trick instead of the "neatness" of the trick itself.

We're not all boy scouts. Those whom are arn't pure either. It's a common an interesting trick (although won't work on any machine made in the past decade or so). Thank you Gore for your contribution.

Gore: The super soaker bit was just to add another piece of flair to the story... ;)

You shoulda punched th person that gave you a bill for water... (I know I know... ethics...I already stated that wasnt the issue I was just wanting to prove that there were alternatives)

So this trick won't work on any new machines either??
