1) " Fart" -- As it applies to Fart Machines Flatulence consists of gases that are produced by symbiotic bacteria and yeasts living in the gastrointestinal tract of mammals and are released through the anus.Flatulence is known colloquially as farting. The primary constituents of flatulence (collectively known as flatus ) are the non-odorous gases nitrogen (ingested), oxygen (ingested), methane (produced by anaerobicmicrobes ), carbon dioxide (produced by aerobic microbes or ingested), and hydrogen (produced by some microbes and consumed by others). Odors result from trace amounts of other constituents(see below). The noises commonly associated with flatulence are caused not by a flapping of the posterior, as commonly thought, but by thevibration of the anal opening. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled, as well as other factors such as moisture and bodyfat.

Exogenous gas is air that is ingested through the noseand mouth. Endogenous gas is produced within the digestive tract. The endogenous gases are produced as a by-product of digesting certain types of food.Flatulence producing foods are typically high in complex carbohydrates, and include beans, milk, onions, yams, sweet potatoes, chickpeas,citrus rinds, chestnuts, broccoli, cabbage, yeast in breads, etc. In beans, endogenous gases seem to arise from oligosaccharides,carbohydrates that are resistant to digestion: these pass through the upper intestine largely unchanged, and when they reach the lower intes...
2) " Machines" -- As it applies to Fart Machines A machine is any mechanical or electrical device that transmits or modifies energy to perform or assist in the performance of tasks. It normally requires an input as a trigger, and transmitsthe modified energy to an output, which performs the desired task. Mechanical mechanisms and Machinse have been in steady use to amplify the abilities of human beings since before writtenrecords were available. The primary difference between simple tools and simple mechanisms or Machunes is a power source and asomewhat independent operation. The term machine generally applies to an assembly of parts operating together to perform work.Generally these devices increase intensity of applied force, changing direction of force,or changing one form of motion or energy into another.The mechanical advantage of a machine is the ratio between the resistance or load, andthe force required to overcome it, although this ratio is not entirely accurate as force is required to overcome friction, as well. To compensate for this, mechanical advantage is calculated as the ratiobetween the distance moved by the force applied, and the distance moved by the resistance. Efficiency of a machine is the degree or percentage to which a machineaccomplishes the work it could do without the restrictions of friction. Modern power tools, automated machine tools, and human operated power machinery complicate this definition greatly. Mahines used to transform heat or other energy into mechanical energy are known as engines.
