Take a transparent glass tube or a plastic pipe. The length of the pipe/tube should be about \(15\) \(cm\) and its diameter should be \(5-7.5\) \(cm\). Also take a piece of thin sheet of a good quality rubber, say, a rubber balloon. Stretch the rubber sheet tightly over one end of the pipe. Hold the pipe at the middle, keeping it in a vertical position. Ask one of your friends to pour some water in the pipe. Does the rubber sheet bulge out? Note also the height of the water column in the pipe. Pour some more water. Observe again the bulge in the rubber sheet and the height of the water column in the pipe. Repeat this process a few more times. Can you see any relation between the amount of the bulge in the rubber sheet and the height of the water column in the pipe?
a. The height of the water column in the pipe causes a bulge in the rubber sheet.
b. The height of the water column affects the pressure that it exerts at the of the container.
