The determination of liquid pressure being due to density, gravity, and depth was presented, and the fact that the pressure was a factor of the depth and not the volume shown using liquid demonstrations. The total pressure on an object immersed in a liquid was shown to be the liquid pressure plus the atmospheric pressure. A cup with holes at varying distances from the bottom was used to show how the water was shot from the holes at different velocities due to the location on the cup. Bouyance and the bouyand force were explained, with the bouyant force being the net upward force on an object. Archimedes principle was stated as the the bouyant force on an immersed object being equal to the weight of the fluid displaced by the object.
