The video shows a car air freshener. The device is rectangular with rounded edges, chrome trim, and clear plastic. It is clipped to the air vent of a car dashboard. Inside the clear plastic is a small propeller that spins rapidly, powered by the airflow from the vent. The word "Catianpai" is visible on the device. The car dashboard is dark gray, with chrome trim around the air vent and a knob visible below the air vent.
