when i squeeze not very hard water rises and pushes the air columna dn makes it shorter
** **
i chose the singly reduced ruler, it will be more precise than the standard ruler but not so small that i can still read the measured values accurately
** **
the air column is about 28.4 cm on the singly reduced ruler
I have the tube softly pinned so it will not move and the air column established. i measured from the end closest to the cap toward the other end of the tube and read 28.4 cm

14 cm
28.4 cm (singly reduced)
16 cm, 23 cm
14, 27.1, 16.8, 23
14, 27, 17, 23.3
14, 25.6, 16.5, 23
14, 26.2, 16.7,23.8
the first value is the where the first mark is after 10 cm of tube but 14 cm above the water level in the bottle. the second value is the length of the air column measured in cm by the singly reduced ruler, the third value is the position of the menisucs of the bottle of the air column before the squeeze and the final value is the position of the meniscus after the squeeze when the water level rises to the first mark.
