A method of spraying a liquid, comprising:

• providing a pressure chamber within an inner container, said inner container surrounded by an outer container;
• providing an outlet valve between said pressure chamber and an outlet channel;
• pressurizing the liquid in the pressure chamber above a certain minimum pressure by moving a piston within a piston chamber through various release and compression strokes;
