Handheld blowdryer

The normal use of a hair dryer.

A blowdryer or hair dryer is an electromechanical device designed to blow cool or hot air over wet or damp hair, in order to accelerate the evaporation of water particles and dry the hair. Blowdryers allow to better control the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds inside each strand. These hydrogen bonds are very powerful (allowing for stronger hair shaping than even the sulfur bonds formed by permanent waving products), but are temporary and extremely vulnerable to humidity. They disappear with a single washing of the hair. Hairstyles using blowdryers usually have volume and discipline, which can be further improved by the use of styling products and hairbrushes during drying to add tension, hold and lift. Blowdryers were invented around the end of the 19th century. The first model was created by Alexander F. "Beau" Godefroy in his salon in France in 1890. The handheld, household hair-dryer first appeared in 1920. Blowdryers are used both in the beauty salon by professional stylists, and in the average household by consumers.

Origin 2[]

A flamethrower is a mechanical incendiary device designed to project a long controllable stream of fire. They were first used during World War I, and widely used in World War II. Some flamethrowers project a stream of ignited flammable liquid; some project a long gas flame. Most military flamethrowers use liquids, but commercial flamethrowers tend to use high-pressure propane and natural gas, which is considered safer. They are used by the military and by people needing controlled burning capacity, such as in agriculture (e.g., sugar cane plantations) or other such land management tasks. They can be designed to either be carried by the operator or mounted on a vehicle.
