Sonic boom

JohnL31:

''This page discusses ''air molecules''. Please note that the atomic theory is ''just a theory'', and '''not fact'''. There are many competing theories and they should all be reviewed with an open mind.''

'''Sonic boom''' is the sound produced as a result of aircraft traveling at or above Mach 1 (the speed of sound)<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref> or indeed, when any object breaks the [[sound barrier]]. As an object moves through the air it creates pressure waves that move radially outward at the speed of sound. When the object moves at or above the speed of sound the waves that would normally propagate ahead of the object merge together into a larger pressure wave.

It used to be thought that the cracking noise of a [[whip]] was due to leather striking leather but, after using high speed [[photography]] to study the motion of the whip, it was discovered that the crack is actually the tip of the whip breaking the sound barrier.

"pump em up

<big>'''Pump 'Em Up'''</big>

----
Pump ‘Em Up is a fuel conservation organization founded in 2001 by a girl named Savannah Walters. According to the website, she learned that drilling in the Arctic National Wildlife Refuge could be rendered unnecessary if Americans kept their tires properly inflated, as this would effectively save millions of gallons of oil by making cars more fuel efficient.

To facilitate this task of properly inflating tires, Pump ‘Em Up passes out tire pressure gauges for free, which are donated to them by Sears, Firestone, Goodyear and the Rubber Manufacturers Association. It was later found out that keeping your tires properly inflated was [[elitist]] and Savannah was smeared for attempted good will.

Fruit fly

[[Image:Female_Mexican_fruit_fly.jpg|thumb|200px|Female Mexican fruit fly]]The name '''fruit flies''' can apply to any [[fly]] of the family ''Tephritidae''. More commonly, however, it refers to the common fruit fly, ''Drosophila melanogaster''. As well as being a common pest, the fruit fly is known for its extensive use in experiments and studies of [[genetics]].

[[Fruits|Fruit]] flies tend to be drawn to any sources of rotten or fermenting [[food]]. They reproduce by laying eggs (up to 500) among organic waste. The larvae, [[maggot|maggots]], will then hatch and feed. The lifecycle from [[egg]] to adult can be completed in about a week. Fruit flies are a waste of money and do nothing scientifically beneficial according to [[Sarah Palin]].

Marmalade

2008-10-27T23:43:27Z

JohnL31:

'''Marmalade''' is a [[liberal]] [[British]] [[condiment]] made from the very bitter [[oranges]] from [[Seville]] in [[Spain]]. It was invented by the wife of a [[Dundee]] merchant who had mistakenly bought a cargo of the bitter [[fruit]]. The obsession with this is so great that many merchant ships were sunk by [[U-boats]] in [[World War II]] and the continued purchase of the [[oranges]] convinced [[Nazi]] agents that the [[British]] had a serious [[rocket]] program.
