Take an emty plastic bottle and make 4 holes at the same heights on different sides.Fill the bottle with water,We can see that water rushes out through all the holes with equal pressure.This simple activity shows that liquid exert equal pressure on the walls of the container at a certain depth

Pressure increases with depth. While you are swimming you feel the pressure of the water on your ear drums.
(inside the ear, the pressure is the same as it is at sea level, outside the water)
This pressure called the hydrostatic pressure is created by the weight of all that water above the diver.

Water squirts further at greater depths
Steps
- Punch holes in side of the container at one inch intervals.
- Fill the container with water.
- Measure the distance from the container that the water squirts out of each hole.
- Plot a graph of depth (distance of hole from top of water level) versus distance water squirts from can.
Keep records
If this is going to be an experiment for a science fair, you will need to record your activities in a log book.
Draw conclusions
This experiment should verify that since the water squirts out further with increasing depth, that the water pressure increases with depth.
