When you squeeze the bottle, the water rises in the vertical tube. The length the water rises mimics the amount of force exerted on the bottle. Therefore, the more force means the greater distance and the smaller force means a lesser distance.

I have chosen to make my level of reduction a 50% reduction. I believe for me personally, it makes sense to make every one centimeter on the system into two recorded centimeters.

Obviously, I had to use several of the measuring devices for this so I taped them together in the procedure given above. The readings at the two ends are the meniscus at 23.25cm and 79.5cm is the measurement for the end of the tube.

The number in the first line tells the vertical position of the mark on the vertical tube which is measured in cm. The number in the second line is the measurement of the air column which is also done in cm. To raise the water by 15 cm, the meniscus traveled on average a little over a cm for the five trials conducted. The first number in the comma delimited sets is the first measurement of the location of the meniscus and the second number is after the vertical tube reached the desire point.

The number in the first line tells the vertical position of the mark on the vertical tube which is measured in cm. The number in the second line is the measurement of the air column which is also done in cm. To raise the water by 35 cm, the meniscus traveled on average a little over a cm for the five trials conducted. The first number in the comma delimited sets is the first measurement of the location of the meniscus and the second number is after the vertical tube reached the desire point.

Good data. That will be valuable in the followup experiment.
