Tinfoil
Tin foil, also spelled tinfoil, is a thin foil (metal), foil made of tin. Tin foil was superseded after World War II by cheaper and more durable aluminium foil, which is still referred to as "tin foil" in many regions (an example of a misnomer). History Foil made from a thin leaf of tin was commercially available before its aluminum counterpart. In the late 19th century and early 20th century, tin foil was in common use, and some people continue to refer to the new product by the name of the old one. Tin foil is stiffer than aluminum foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminum and other materials for wrapping food. Because of its corrosion resistance, oxidation resistance, availability, low cost, low toxicity, and slight malleability, tin foil was used as a filling for tooth cavity, tooth cavities prior to the 20th century. The first audio recordings on phonograph cylinders were made on ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phonograph Cylinder
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for Sound recording and reproduction, recording and reproducing sound. Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to Phonograph record, their disc-shaped successor, these hollow cylinder, cylindrical objects have an audio recording engraved on the outside surface which can be reproduced when they are played on a mechanical cylinder phonograph. The first cylinders were wrapped with tin foil but the improved version made of wax was created a decade later, after which they were commercialized. In the 1910s, the competing disc record system Format war, triumphed in the marketplace to become the dominant commercial audio medium. Early development In December 1877, Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. Tin f ...

Aluminium Foil
Aluminium foil (or aluminum foil in American English; occasionally called tin foil) is aluminium prepared in thin metal leaves. The foil is pliable and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Annual production of aluminium foil was approximately in Europe in 2014, and in the U.S. in 2003."Foil & Packaging" . The Aluminum Association (USA). Approximately 75% of aluminium foil is used for of |

Tin Foil Hat
A tin foil hat is a hat made from one or more sheets of tin foil or aluminium foil, or a piece of conventional headgear lined with foil, often worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and mind reading. The notion of wearing homemade headgear for such protection has become a popular stereotype and byword for paranoia, persecutory delusions, and belief in pseudoscience and conspiracy theories. "Tin foil" is a common misnomer for aluminium foil in English-speaking countries; packaging metal foil was formerly made out of tin before it was replaced with aluminium. Origin Some people – "Tin Foil Hatters" – have a belief that such hats prevent mind control by governments, spies, mobsters, corporations, extraterrestrial, or paranormal beings that employ ESP or the microwave auditory effect. People in many countries who believe they are " targeted individuals", subject to government, corporate, or criminal sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Foil (metal)
A foil is a very thin sheet of metal, typically made by hammering or rolling. Foils are most easily made with malleable metal, such as aluminium, copper, tin, and gold. Foils usually bend under their own weight and can be torn easily. For example, aluminium foil is usually about , whereas gold (more malleable than aluminium) can be made into foil only a few atoms Atoms are the basic particles of the chemical elements.

Misnomer
A misnomer is a name that is incorrectly or unsuitably applied. Misnomers often arise because something was named long before its correct nature was known, or because an earlier form of something has been replaced by a later form to which the name no longer suitably applies. A misnomer may also be a word that is used incorrectly or misleadingly. The word "misnomer" does not mean " misunderstanding" or " popular misconception", and a number of misnomers remain in common usage — which is to say that a word being a misnomer does not necessarily make ''usage'' of the word incorrect. Sources of misnomers * An older name being retained after the thing itself has changed (e.g., tin can, mince meat pie, steamroller, tin foil, clothes iron, digital darkroom).

Tooth Cavity
Tooth decay, also known as caries,The word 'caries' is a mass noun, and is not a plural of 'carie'.'' is the breakdown of teeth due to acids produced by bacteria. The resulting cavities may be a number of different colors, from yellow to black. Symptoms may include pain and difficulty eating. Complications may include inflammation of the tissue around the tooth, tooth loss and infection or abscess formation. Tooth regeneration is an ongoing stem cell–based field of study that aims to find methods to reverse the effects of decay; current methods are based on easing symptoms. The cause of cavities is acid from bacteria dissolving the hard tissues of the teeth ( enamel, dentin and cementum). The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. If mineral breakdown is greater than buildup from sources such as s ...
