Have you ever wondered how water pressure works? Let’s explore this concept with a fun and simple experiment using a plastic bottle, a drill, some masking tape, and a tray.
First, take a plastic bottle and mark three points on it. Label these points A, B, and C. Point A should be near the top, B in the middle, and C at the bottom of the bottle.
Next, carefully drill a small hole at each of these points. Cover each hole with a piece of masking tape to keep the water inside when you fill the bottle.
Now, fill the bottle with water all the way to the top. Place the tray underneath the bottle to catch any water that comes out. Quickly remove the tape from all three holes and observe what happens.
You’ll notice that the water coming out of hole A, which is at the top, doesn’t go very far. This is because the water pressure is the weakest at this point. At hole B, in the middle, the water spurts out a bit further because the pressure is stronger. Finally, at hole C, which is at the bottom, the water shoots out the furthest. This is because the water pressure is the strongest here.
The reason for this difference in water pressure is that the pressure increases with depth. The more water there is above a point, the greater the pressure. So, the water at the bottom of the bottle has the most pressure pushing down on it, making it spurt out the furthest.
This experiment shows us how water pressure works in a simple and visual way. It’s a great way to understand one of the many interesting properties of liquids. Try it out yourself and see the effects of water pressure in action!
Thanks for exploring with us. See you next time!
Water Pressure in Everyday Life: Next time you take a bath or shower, pay attention to how the water flows. Does the water come out faster or slower when you adjust the showerhead to different heights? Discuss with a family member why you think this happens and how it relates to the experiment you did with the bottle.
Create a Water Fountain: With the help of an adult, use a garden hose to create your own water fountain. Try holding the hose at different heights and angles. Observe how the water pressure changes and how far the water can reach. Can you make the water go higher or further by changing the position of the hose?
Pressure in Nature: Go on a nature walk and look for examples of water pressure in action. Can you find a stream or river? Notice how the water moves faster in some places and slower in others. Think about what might be causing these changes in speed and pressure. Share your observations with your class or family.

Properties of Matter: Pressure in Liquids
How can we observe the effect of water pressure?
Here we have a plastic bottle, a drill, masking tape, and a tray.
Mark out three points on the plastic bottle and label them A, B, and C. A is at the top, B is in the middle, and C is at the bottom.
Now let’s drill a hole at each point. Cover the holes with a piece of tape and fill the bottle with water.
Place the tray at the base of the bottle and quickly remove the tape.
The water pressure is the least at hole A; the water spurts out the shortest distance. There is less water pressure at hole B; the water spurts out at a shorter distance. The water pressure at hole C is the greatest; the water spurts out the furthest.
See you next time!
