What is Bellows?
[[File:Old bellow.jpg|thumb|right|A blacksmith's bellows in [[Australia]]]] A '''bellows''' is something that blows air into a small opening in order to make something work. The bellows will have a kind of sack which has air in it. When the sack is squeezed the air is pushed out. Bellows can be quite small and operated by hand, for example for stoking a fire in an open fireplace. They can also be very large, such as bellows that produce air for a large [[pipe organ]] to be played. Such bellows used to be pumped by hand (sometimes by several people), but nowadays [[electricity]] is used. Bellows are used by [[blacksmith]]s or metalworkers for [[smelting]] and [[welding]]. They are also used in small [[musical instrument]]s such as [[bagpipes]], [[accordion]]s and [[concertina]]s. The [[harmonium]] has bellows which the player operates by pumping pedals with their [[feet]]. [[Category:Tools]]
