Fart Machine

This fart machine replicates the sounds that can be achieved by practicing. It is called the Fart-O-Tron. 

Raspberry Patterns

Farts

Blowing a raspberry comes from the Cockney rhyming slang "raspberry tart," fart. Rhyming slang was particularly used in British comedy to refer to things which would be unacceptable to a polite audience, particularly on the BBC.

One of the most famous uses of the Bronx cheer is in the song "Der Fuehrer's Face" (from the Disney animated film of the same name), as recorded by musical comedian Spike Jones in 1942, which shows disdain for Adolf Hitler with the repeated refrain "We Heil! (Bronx cheer) Heil! (Bronx cheer) Right in Der Fuehrer's Face!"

 

Blowing a raspberry

Blowing a raspberry or strawberry or making a Bronx cheer is to make a noise signifying derision (and/or silliness), made by sticking out the tongue between the lips and blowing to make a sound reminiscent of flatulence. In the terminology of phonetics, this sound can be described as an unvoiced linguolabial trill. It is never used in human language phonemically (i.e., to be used as a building block of words), but it is widely used across human cultures.

Raspberry Pattern

The Raspberry Pattern represents the term "raspberry", that  is used in its irreverent sense, as in "blowing a raspberry." which derives by the act of producing a noise similar to that created by flatulence by the mouth  as it forms the  protracted expulsion of air through the lips to reproduce the sound similar to that of gas as it is passed through the rectum. Flatulence is produced as a mixture of gases that are byproducts of the digestion process of mammals and other animals, that takes the form of flatulence. The mixture of gases is known as flatus in medical speak, informally as a fart, or simply (in American English) gas, and is expelled from the rectum in a process colloquially referred to as "passing gas", "breaking wind" or "farting". Flatus is brought to the rectum by the same peristaltic process which causes feces to descend from the large intestine. The Raspberry Pattern is the formation of the mouth as the noise is emitted. The noises commonly associated with flatulence are caused by the vibration of the anal sphincter, and occasionally by the closed buttocks.
