This experiment revealed a lot about compressors, which are commonly used for spraying on clothes during the drying process. The PP (Kmno4) is placed in a small cup-like tool, and a nozzle attached to it allows compressed air to enter, and turning on the trigger activates the air coming from the cylinder. This breeze is responsible for the accumulation of PP solution on the surfaces of the fabrics. We were also familiar with the roles of the various components of these devices.
