Airbrush/Spray gun
The airbrush is a kind of mini paint gun. It spray-paints by making air run along a metal rod ending in a point and passing through a nozzle. The pressurized air is channeled and passes by an opening that supports the cup. The resulting airflow draws in the solution contained in the cup. The solution reaches the end of the needle in the tip of the nozzle. It then turns into a spray of micro-droplets that are sprayed from a distance.
