How does the system behave and how does it 'feel'?
When I first sqeezed the system, water in the vertical tube began to rise slightly. The water in the pressure tube remained to me what looked the same. I then squeezed again, this time harder. I was able to see the change in air column. The water kept rising to the top of the vertical column while the pressure column air was getting smaller and smaller.
Length of the air column in units of your measuring device:
I have used the regular sized centimeter ruler because I feel this is the easiest to see and count.
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.
39.3, 16.9
I found these measurments by first measuring the air column from the start of the system, when it first came out of the stopper to the where the water was. I then took another measurment from the other end of the water to the end of the tube.

Your data look good, and should give you good results in Part 2 of this experiment.
