A bracelet is an article of jewelry that is worn around the wrist. Bracelets can be manufactured from leather, cloth or metal, and sometimes contain rocks, wood, and shells. Bracelets, such as allergy bracelets and hospital tags, are also used for medical and identification purposes. In the late 1980s, snap bracelets were very common. These were felt-covered metal bracelets that curve around one`s wrist. Modern metal bracelets are used as punk jewelry items, and are available in different shapes and sizes. One of the types of metal bracelets includes Magnetic Bracelets. Magnetic Bracelets are easy to use as they are fastened using magnetic power.

Fire is a phenomenon of combustion manifested in intense heat and light in the form of a glow or flames. The word ?fire` when used with an indefinite article is commonly used to describe either a fuel in a state of combustion, such as a campfire or a fire in a fireplace or kitchen stove. Otherwise, it is used to describe an instance of violent, destructive and uncontrolled burning, such as a wildfire and fires in buildings and vehicles. Since its discovery by humans, fire has been considered to be one of the most powerful and important elements in the progression of humankind. A conflagration is a large, uncontrollable fire, whether it is an urban fire that affects many buildings or if it is a rural fire that burns many acres. The phenomenon of the firestorm often fuels such large fires. Fire is simply glowing gas and other combustible particles such as carbon. It is not plasma, as it is not hot enough to reach such high ionization as is required of plasma. This state of matter can be generated through focused concentrations of energy, such as fuel being exposed to an already open flame or the sun`s rays focused through a lens. This can also be attained by an exothermic chemical reaction usually accompanied by intense heat released during a rapid loss of electrons from the combustible material, such as striking a match. Fire may be visible as a brilliant glow or flames and may produce smoke. Fires start when a flammable or combustible material with an adequate supply of oxygen or another oxidizer is subjected to enough heat. The common fire-causing sources of heat include a spark, another fire such as an explosion, a fire in the oven or fireplace or a lit match, lighter or cigarette and sources of intense thermal radiation, such as sunlight, a flue, an incandescent light bulb or a radiant heater. Fire risk is defined as the risk or potential hazard of catching uncontrolled fire. Normally, fire risk is described for specific items. Fire risk is categorized according to the flammability of an item. A more flammable item carries more fire risks and a less flammable item has fewer fire risks.
