If I partially fill a bottle with water (even cold water), add some soap, close it up and shake it; when I open I open it back up, it tends to spurt / hiss / generally act like it was under pressure all of a sudden, even though the total volume of liquid inside is still the same.
Why?
Please and thank you xxx

Are you sure the pressure increases? When you shake a bottle of soda, the pressure does not increase. What happens is that the shaking process creates some bubbles that serve as starting points for more dissolved gas to form bubbles that come out of the liquid.
