Spandex or elastane is a synthetic fiber known for its exceptional elasticity. It is strong, but less durable than its major non-synthetic competitor, natural latex. It is a polyurethane-polyurea copolymer that was invented in 1959 by chemists C. L. Sandquist and Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia.

Spandex or elastane is a synthetic fiber known for its exceptional elasticity. It is strong, but less durable than its major non-synthetic competitor, natural latex. It is a polyurethane-polyurea copolymer that was invented in 1959 by chemists C. L. Sandquist and Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia. When first introduced, it revolutionized many areas of the clothing industry.The name "spandex" is an anagram of the word "expands". It is the preferred name in North America; in continental Europe it is referred to by variants of "elastane", i.e. elasthanne (France), elastan (Germany), elastano (Spain), elastam (Italy) and Elasthaan (Netherlands), and is known in the UK, Ireland, Portugal, Brazil, Argentina, Australia, New Zealand and Israel primarily as Lycra. Brand names for spandex include Lycra (made by Koch subsidiary Invista, previously a part of DuPont), Elaspan (also Invista), Acepora (Taekwang), Creora (Hyosung), INVIYA (Indorama Corporation), ROICA and Dorlastan (Asahi Kasei), Linel (Fillattice), and ESPA (Toyobo)....

A diaper (also called a nappy in South Africa, Ireland, United Kingdom, New Zealand, Australia and Zimbabwe) is a type of underwear that allows one to defecate or urinate in a discreet manner, without the usage of a toilet. When diapers become soiled, they require changing; this process is sometimes performed by a second person such as a parent or caregiver. Failure to change a diaper on a sufficiently regular basis can result in skin problems around the area covered by the diaper.Diapers are made of cloth or synthetic disposable materials. Cloth diapers are composed of layers of fabric such as cotton, hemp, bamboo or microfiber and can be washed and reused multiple times. Disposable diapers contain absorbent chemicals and are thrown away after use. Plastic pants can be worn over diapers to avoid leaks, but with modern cloth diapers, this is no longer necessary.[citation needed]Diapers are primarily worn by children who are not yet potty trained or experience bedwetting. However, they have also been used by adults with incontinence or in certain circumstances where access to a toilet is unavailable. These can include those of advanced age, individuals with certain types of physical or mental disability, and people working in extreme conditions, such as astronauts. It is not uncommon for people to wear diapers under dry suits....

Cheerleading /ˈtʃɪərlidɪŋ/ ranges from yelling to intense physical activity for sports team motivation, audience entertainment or competition based upon organized routines. The routines usually range anywhere from one to three minutes, which may contain many components of tumbling, dance, jumps, cheers and stunting in order to direct spectators of events to cheer for sports teams at games or to participate in cheerleading competitions. The yellers, dancers and athletes involved in cheerleading are called cheerleaders. Cheerleading originated in the United States, and remains predominantly American, with an estimated 1.5 million participants in all-star cheerleading. The presentation of cheerleading as a sport to a global audience was led by the 1997 start of broadcasts of cheerleading competition by ESPN International and the worldwide release of the 2000 film Bring It On. Due in part to this recent exposure, there are now an estimated 100,000 participants scattered around the rest of the world in countries including Australia, Canada, China, Colombia, Finland, France, Germany, Japan, the Netherlands, New Zealand and the United Kingdom....
