Describe a simple experiment to demonstrate that the pressure in a liquid increases with depth.

Answer Text:
• Using a nail, make three holes, A, B and C, of the same diameter along a vertical line on one side of a tin.
• Fill the tin with water as shown in the figure.

• With the tin full of water, observe the jets of water from the holes A, B and C.
Observation
The lower hole, A, throws water the farthest distance z, followed by B distance y and lastly C distance x.
Conclusion
Pressure of water at A is greater than pressure at B and pressure at B is greater than at C. Hence, pressure increases with depth.
