Solution

Activity: To show that liquid pressure at a given depth is the same in all directions.

Theory:
Pressure is defined as the force acting per unit area. At any point in a fluid, it is the same in all directions.
$p = h d g$ where h is the height of the liquid,d is the density of liquid and g is the acceleration due to gravity.
Materials required: Polythene bag, water, and safety pin or any small nail.
Procedure:
Make holes of the same size on the polythene bag with the help of a small safety pin or small nail.
Now fill the bag with water.
Conclusion: We will notice that water starts sprinkling because it exerts pressure in all directions.
