Question
Describe a simple experiment to demonstrate that a liquid enclosed in a vessel exerts pressure in all directions.

Solution
Take a can or large plastic bottle filled with water. Place it on a horizontal surface. Make a series of holes in the wall of the vessel anywhere below the free surface of the liquid. The water spurts out through each hole. This shows that the liquid exerts pressure at each point on the wall of the bottle.
