Why is it that when someone farts it lingers in that spot and then it disappears where does it go?

it's called the process of diffusion. as a smell spreads out its molecules use the air molecules to move away as gas molecules are so free. soon there is very little atoms of the fart smell left that it is unsmellable to the human nose although it's never truly gone!

carnival baloons reach a specific hieght at which they stop verical movement and start to float around losing gas and eventually coming down to earth. i dont know why hey stop movung up but my guess is that they stop when the thickness of air at that altitude is less than the density of helium.

Think of where it is coming from... \n\nThat HOLE isn't exactly the most beautiful place and (I don't know about you - but for me -  I don't particularly like to invision breathing the fumes that come out of that orifice)\n\nI think for many people it is similar - just hearing a fart makes them think - "Eww I am breathing the fumes that came out of someone elses butt!"  It's just gross.  \n\nSo yes - even though "smelly" ones are worse, the non-stinky variety are still YUCK because they are there.  We are forced to hear and then breath that air around you after KNOWING that you just farted.  :p

Eliminate often. The gas mixes with what's in the intestine...keep the intestine clear and it reduces the smell...

Woooooooo hoooooooooo hooooooooo\nU tried something new baby.\nI don know how I like it but may b water vapour molecules that get stuck up with the fart molecules make the smell more denser and more grossy.........\nI m outa here or ur fart may come up any time now......\n\n\nPPPPPHHHHHHHHHwwwwwwwwtttttttttttttttttt.................................

It's a large amount of air pushing through a small space. It's not the "buns" flapping. It happens at the point of exit. \n\nThere really isnt any more delicate way to put it.\n\nI cant believe I just answered this question. I need a life!

Actually farts are aromatic and you can't really capture them in your hand.  They disperse like any other scent.  Most people don't cup their ass$ to scoop it up though.  It is to revealing and takes the fun out of "who done it"!  \n\nProper fart etiquette is to just let it fly!  Fart containment isn't healthy so it is always best to fart now and never mention it, unless you would like to claim ownership.\n\nPersonally I claim mine, for they are truly from the depths of my bowels!  And honestly? Who can complain with that level of anal openness?

When a woman "queefs" she is NOT expelling gas from her vagina. It is impossible to expel gas from that opening because it does not connect to the small intestine.\n\nA "queef" is simply air (just air like the air you breathe) that gets trapped in the vaginal canal. Air can get trapped in the canal during rigorous sex or if the woman works her kegel muscles (the muscles lining the vaginal canal) and moves air into the vagina by accident.\n\nIt is natural function and no woman should be embarassed if she "queefs" during sex.

Most fart gas comes from swallowed air and consists largely of nitrogen and carbon dioxide, the oxygen having been absorbed by the time it reaches the anal opening. These gases are odorless, although they often pick up other (and more odiferous) components on the way through the bowel. They emerge from the anus in fairly large bubbles at body temperature. A person can often achieve a good sound with these voluminous farts, but they are commonly (but not always!) mundane with respect to odor, and don't feel particularly warm.\n    Another major source of fart gas is bacterial action. Bacterial fermentation and digestion processes produce heat as a byproduct as well as various pungent gases. The resulting bubbles of gas tend to be small, hot, and concentrated with stinky bacterial metabolic products. These emerge as the notorious, warm, SBD (Silent-But-Deadly), often in amounts too small to produce a good sound, but excelling in stench.

easy\n\nchemical process, when we process foods we divide the food with the stomach acids, this creates a chemical efect that relises butane and other gases in your intestine, when you fart, you can truly light up your fart and it will burst..\n\nlol but dont do it with out underwear or you will have bad experiences :(

The noxious gas comes out and quickly pushed out in bubbles, and at each bubble there's one clap, the larget the fart the more bubbles.  You'll fart louder if you are sitting with your cheeks held tightly together because the claps will be harder.

if you fart continuously for 8 years, you can create energy enough to make an atomic bomb. So if everybody farted, it would be like a few atomic bombs exploding.

Farts are not a single molecule.  In fact, they are primarily aerosolized feces.  The smaller molecules that are a byproduct of digestion often become gaseous in the intestinal tract and are expelled as farts.\n\nThere are far too many possible compounds in farts to list them, but a popular one to talk about is methane.  Only 1/5th (or so?) of humans produce methane in their farts, a flammable molecule that doesn't smell particularly good.\n\nhere is a page with a similar but more detailed answer:\nhttp://www.heptune.com/farts.html

The quiet effect last until you fart again.

"When we eat, we also swallow air. Also, when the food gets digested in the intestines, gas is produced. These gases when passed out through the intestine form the @nus into the air are called farts. The gases that make farts smell bad contain ammonia and hydrogen sulfide which are made in the intestine. And eating oily spicy food and drinking lots of soda makes you fart even more."

Generally guys fart more than girls. I heard that this is due to the fact that girls can't shut up long enough to build up the required pressure!! \n\nOk.... maybe its also that we have more  ladies than gentlemen, but as a general rule, gas trapped  in the body can come out as a fart or a burp depending on where it is at that moment, and it is not only methane. Sometimes whem you swallow your food or drink with a lot of air, you also get good old air in your tummy, and that can result in burps or farts.\n\nExact quantum would depend on the size of the body. Imagine that a skinny 90pounder would store less gas than a 250pound person.

A fart is the cry of an imprisoned turd.  I'm not sure if the actual fart knows where it came from, but the turd apparently does, if it's screaming to get out.
