Why does Trade Secret Furniture Polish sometimes spray a stream and othertimes a spray?

Our experience with Trade Secret Furniture Products shows that if you push the mister pump gently (half-way, three-quarters etc…) it will spray in a stream pattern. If you completely push the mister pump from top to bottom in a single motion it will spray a circular spray pattern. By using the smooth movement and complete depression of the mister pump, greater pressure is generated. This pressure is required to create and deliver the mist as opposed to the stream.
