title: Hydrostatic Pressure
aka: pressure vrs. depth

A water filled manometer is attached to a "probe" made up of a shallow cylinder covered with a flexible diaphram.  The probe is attached to a handle that will allow it to be lowered into a water filled tube.  The pressure increases with depth.   Also, the top of the probe handle can be pulled out to rotate the probe to show that the pressure is the same in all directions at a specific depth.

    Would this work on the moon? (ie. with lower gravity?)
    What would happen in a higher density fluid?
     What would change if the manometer used a higher density fluid?
