[font=Verdana, Arial, Helvetica, sans-serif]Why do farts seem to follow the farter?[/font]
This is unlikely, because most underwear is made of material with a fairly high tensile strength, meaning that it can endure a certain level of extensional stress without brittle failure. Furthermore, the porous nature of underwear fabrics allows much of the fart's force to pass through the spaces rather than to stress the fabric.

Why do farts smell so much worse in a shower than anywhere else?[/font]
There are several factors. First of all, a shower is a small, enclosed space, so the fart
gas is more concentrated, and the high turbidity of the air in the shower circulates the gas through the space effectively. Secondly, the high humidity and high temperature conditions in the shower enhance a person's sense of smell and taste. The farts don't actually smell worse, it's just that we can smell them better than usual. Similar conditions prevail in the bathtub.

If Venus's surface temperature were a mere 200 to 300 degrees Fahrenheit, liquid water could exist there because of Venus's extremely high atmospheric pressure. But the temperature on Venus is almost 900 degrees Fahrenheit. Because humans are mostly water, a person would not simply emit gas on Venus, but would become gas, a whole-body fart. Venus already has a lot of sulfur compounds in its atmosphere, so a fart on Venus probably wouldn't even produce much of a noticeable smell.
[font=Verdana, Arial, Helvetica, sans-serif]If you were in space without a suit, would a fart have the energy to propel you forward?[/font]
Yes, a fart should propel you forward, since there is virtually no opposing force in the form
of friction or gravity to counteract the force of the fart.

Is it possible to freeze farts, and would they still be smelly after they are defrosted?[/font]
The water vapor component of farts would freeze quite readily, but to freeze the entire
fart would require high pressure and low temperature conditions such as that used to produce dry ice. The fart's composition would be unchanged by the process, and hence would still be smelly upon reversion to the gaseous state.

Are farts acid, neutral or alkaline?[/font]
Farts tend to be rich in carbon dioxide, and may also contain hydrogen sulfide, the substance primarily responsible for the stench of farts. If a fart were to be dissolved in water, carbon dioxide would interact with water to produce carbonic acid, and hydrogen sulfide would make hydrosulfuric acid. These are both weak acids, so farts (at least when in solution) are mildly acidic.

Is it possible for a fart to rip your underwear?[/font]
The sense of taste detects substances that are either liquid or dissolved in liquid.
You can taste a fart when the fart's constituent molecules go into solution in your saliva.

Do fart particles disperse in the air and float around until they hit something and then stick to it?[/font]
The ultimate fate of fart particles depends on the nature of the particles. Gas molecules
mostly mix into the atmosphere, although some may react chemically to form new substances. Aerosolized particles of liquid and solid poop probably do condense on surfaces. Most of these particles are polar (with a positively charged end and a negatively charged end) and are attracted to other polar substances or charged surfaces like a monitor screen. Other fart particles condense on microscopic water droplets in the air if the humidity is very high (as in a bathroom), and some particles go into solution in water.
[font=Verdana, Arial, Helvetica, sans-serif]Where does the word "fart" come from?[/font]
According to Eric Partridge in his excellent book of word origins (Origins: A Short
Etymological Dictionary of Modern English), our word "fart" comes from the Old English word "feortan", presumably of echoic origin, meaning that the word was chosen to sound like the object named
