When the bottle is squeezed the pressure pressure that is created pushes the water in the tube down the tube and away from the bottle. The water increases vertically in the tube. I feel like it isn't really that difficult to make the water move.

I chose the reduction 1-2, signifying that a measurement of 2 cm on my reduced measuring device is equivalent to 1 cm on the actual scale. This option was my choice because it allowed for more detailed and precise measurements compared to the full scale.

53.5 cm.
I measured the mark where the meniscus stopped and 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 28.25 cm from 81.75 cm we get the air column length of 53.5 cm.

The first number represents how far the water had to vertically travel 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 and the second numbers are the distances that the meniscus is after the bottle was squeezed to get the bottle to get the water to travel to the first mark in the vertical tube.

The first number represents how far the water had to vertically travel 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 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.

The first number represents how far the water had to vertically travel 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.

Good data. You'll use it in the next experiment.
