As I squeeze the bottle, the water rises up the vertical tube. The water moves the same amount in the pressure tube (away from the bottle). As I apply more pressure, it begins to get harder to squeeze the bottle.

The measurement was taken from the capped end to the water meniscus after the air column

20, 8.5
The first value is the vertical position of the first mark on the vertical tube to the water surface, the second values is the length of the air column,the third through seventh values are the numbers collected from measuring the distance between the starting and ending position of the meniscus

As before, the first value is the vertical position of the first mark on the vertical tube to the water surface, the second values is the length of the air column,the third through seventh values are the numbers collected from measuring the distance between the starting and ending position of the meniscus

Once again, the first value is the vertical position of the first mark on the vertical tube to the water surface, the second values is the length of the air column,the third through seventh values are the numbers collected from measuring the distance between the starting and ending position of the meniscus
