This video shows a little girl having a pretty nasty sinus infection. She is using a nasal wash produc from a brand called "Nasopure" which is filled with warm water and salt(from the manufacturer).
As you watch the video, an enormous amount of yellow mucus comes out of her nose which gives you a sense of relief.
You can see that this little girl is used to having water passing through the sinuses as she stays relatively relaxed.
