An AIRBRUSH is an atomizer for spraying paint. It is a small, air-operated tool that sprays paint or other substances through a small nozzle. Airbrushes are used in a variety of applications, including painting, illustration, and cosmetics. They are also used to create special effects in movies and television. Airbrushes are typically powered by a compressor, which forces air through the nozzle and atomizes the paint into a fine mist.
