Unlike a regular spray bottle that uses a simple tube, a powder spray bottle has a unique pump mechanism that uses airflow to fluidize the powder.
How it works (The Basic Principle):
When you press the pump, it creates a burst of air.
This air travels through a dedicated tube and into the powder chamber.
The air agitates and "fluidizes" the powder, turning it into a dusty mist.
This mist is then expelled through the nozzle, creating a fine, even spray.
