Your 'measuring atmospheric pressure' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

** How does the system behave and how does it 'feel'? **
When I squeeze, the water in the vertical moves up when pressure is applied. When I release, it moves back down to where it began.
** Length of the air column in units of your measuring device: **
I chose the second distortion due to its large numbers and easy to read lines. It is very easy to see and should be beneficial.
** Your report of the vertical position of the first mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **

I held my paper ruler up to the tube and measured it. I realize that this is not accurate but it is helpful to get precise measurements.

10cm above water on the tube.

20.7, 22.1
21.1, 23.4
20.9, 22.4
21.0, 23.1
20.7, 22.7
This shows that before I squeezed the water, it was settled at the first point, then the level rose to the second point.

20.7, 33.2
20.9, 33.0
21.2, 32.9
21.0, 33.4
This shows that before I squeezed the water, it was settled at the first point, then the level rose to the second point.

21.0, 67.4
21.8, 67.0
22.0, 69.9
21.6, 68.4
22.3, 68.1
This shows that before I squeezed the water, it was settled at the first point, then the level rose to the second point. My bottle is kind of old and is becoming weak. When I release sometimes parts of it stay indented so this may affect some of my readings.
