Introduction to working principle: The motor rotates at a high speed, driving the fan to exhaust air from the bottle mouth to the outside of the bottle, thereby creating negative pressure inside the bottle. This negative pressure then generates suction at the bottle opening, drawing paper scraps into the bottle. The bottle cap can be closed normally and unscrewed when in use.
Tip: Buyers of this kit need to provide their own beverage bottle (the most common round water bottle) and 2 AA batteries!!
