The difference of air pressure between the surface of the liquid and inside the straw or an ink filler pushes the liquid up. Hence, both of them work on atmospheric pressure.

Explanation:
How a straw works:
- When you suck on a straw, you create a vacuum inside the straw.
- The atmospheric pressure outside the straw is higher than the pressure inside the straw.
- This pressure difference pushes the liquid up the straw and into your mouth.
How an ink filler works:
- When you press the top of an ink filler, you compress the air inside the tube.
- The higher atmospheric pressure outside the filler pushes the ink out of the tube onto the paper.
- This demonstrates that air exerts pressure.
Falling of raindrops:
- Raindrops fall due to the force of gravity and not because of air pressure.
- The pressure exerted by air is responsible for the phenomena mentioned above, not the falling of raindrops.
Conclusion:
Both the examples of how a straw works and how an ink filler works demonstrate that air exerts pressure. This is because the movement of liquid in the straw and ink in the filler is dependent on the pressure difference between the atmosphere and the inside of the respective objects.
