 Sniff,
sniff… something stinks. Oh, did you just
fart? Sometimes your fart can smell really bad. But don’t worry. Farting
is an important part of your life. No one can avoid it or prevent it. Do you know what
it actually is and how it actually
works? Do you know where farts come from? This week, let’s
learn some interesting facts about your fart!
Farting is the act of passing gases from your intestines through your anus. Some will smell bad,
while others will sound like a trumpet! Farts are the product of a
mixture of air and gases in the digestive tract that are
a by-productof the body’s digestion process process.
 What
is a fart’s gas made of? Farts are composed of a variety of gases in different
proportions. Nitrogen is the main ingredient, making up 59
percent of the average fart. Hydrogen makes up 21 percent.
The rest are fairly small, in proportion with 9 percent carbon dioxide, 7 percent
methane, and 3 percent oxygen.
Hydrogen sulfide makes up the last
1 percent.
 Then, what
makes farts stink? The odor of farts comes from small amounts of hydrogen
sulfide gas. In the U.S., there is a company that sells underwear designed to absorb the odor of farts!
Why do farts make funny noise? The sounds are produced
by vibrations of the anal opening. Sounds depend
on the speed of release of the gas and the
tightness of the sphincter
muscles of the anus. A big
loud fart is rarely a stinky one.
The average person farts 14 times per day and produces a half liter
of fart gas. Eating beans, corn, cabbage, milk, bread, eggs,
raisins, onions, garlic, and sweet potatos make you fart.
Then, do animals fart, too? Of course they do! The top 10 farting
animals are as follows: termites, camels, zebras, sheep, cows, elephants,
Labradors, humans (vegetarians),
humans (non-vegetarians), and gerbils. To our surprise, termites alone
produce more methane than cows and even man-made polluting machinery.
Surprisingly, even dead people still fart! |
