bellows

Bellows are devices used to generate a strong blast of air. They consist of a flexible, airtight chamber that expands and contracts. When the bellows are squeezed, air is pushed out, creating a powerful airflow, often used to fuel a fire or to enhance the intensity of a flame. You might see bellows in blacksmith shops, where they help maintain high temperatures for forging metal. Additionally, bellows can be found in musical instruments, such as accordions or pipe organs, where they supply air for sound production. Overall, they are essential tools for various applications that require controlled airflow.
