Title: Dynamic Manometer

Description: When the fluid is raised in the column by creating a fixed mass of air at the top above the water with your thumb, the fluid gains potential energy. As the thumb is released from the top of the tube, the fluid becomes free to move. The water oscillates around the bend of the tube because of its inertia and eventually reaches equilibrium due to viscous damping. For a glycerin/water mixture, the damping coefficient is much higher and the system oscillates less.
