thumb|Diagram of fireplace hand-bellows Bellows are a device constructed to expel a controlled blast of air. The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to fill the cavity when expanded, and with a tube through which the air is forced out in a stream when the cavity is compressed. It has many applications, in particular blowing on a fire to supply it with air.
Bellows are a device that expels a controlled blast of air by expanding and contracting a flexible bag fitted with a valve and tube. They are particularly useful for blowing air onto a fire to help it burn more intensely.
