Source sentences:
text: The Cartesian diver shows that air is compressable and water is incompressable because when you squeeze the contanir the pressure you caused is distrubited equal throughout the container (Pascal's law) and the volume of air in the pipet decreases because of the increased pressure of the water surrounding the pipet (Boyle's law).
text: This water in turn exerts additional pressure on the air bubble inside the diver; because the air inside the diver is compressible but the water is an incompressible fluid, the air's volume is decreased but the water's volume does not expand, such that the pressure external to the diver a) forces the water already in the diver further inward and b) drives water from outside the diver into the diver.
