When i squeeze the bottle, the pressure that is created from the squeeze pushes the water in the pressure tube down the tube and away from the bottle. The water rises in the vertical tube upwards. I feel that it is not very difficult to make the water move.

I chose to use the reduction of 1:2. This signifies that a measurement of 2 cm on my reduced measuring device is equivalent to 1 cm on the actual scale. I chose this option because it allows for more detailed and precise measurements compared to the full scale.

53.5 cm
I measured the mark where the meniscus stopped and it was recorded to be at 28.25 cm. Then the second mark where the end of the tube stopped was measured to be 81.75 cm. Subtracting these, 81.75 - 28.25 = air column length of 53.5 cm.

The first number represents how far the water had to travel vertically in the tube to reach the first mark. The second number is the length of the air column. The rest of the numbers are equally calculated with the first number being the distance measured of the meniscus before the squeeze; The second numbers after the comma are the distance that the meniscus is at after squeezing the bottle to get the water to travel to the first mark in the vertical tube. All units are in cm.

You appear to have good data, which will be beneficial in the second part of this experiment.
