How does the system behave and how does it 'feel'?
When pressue increases on the bottle the water goes into the vertical tube and the water in the other tube shortens the air column.
Length of the air column in units of your measuring device:
single-reduction, more precision but still able to distinguish between the units
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.

Measured cap to water, water to end of the tube in the bottle.
Your report of the vertical position of the second 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.
