** How does the system behave and how does it 'feel'? **

The harder I squeezed the higher the water rose, and the air column went shorter, therefore the more energy I put intot he system, water got higher but air decreased

** Length of the air column in units of your measuring device: **

I choose the single reduction, because it was smaller than a normal ruler yet easy to read

** Your report of the vertical position of the first mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **

I used a cm ruler, and taped 2cm rulers together, therefore my results will be in cm.

** Your report of the vertical position of the second mark relative to the water surface of the first mark, the length of the air column in units of your selected measuring device, and the two meniscus positions observed with each of your five trials. **

I would squeeze the bottle until it reached the first mark on the vertical tube and I used a cm reduced ruler to amke my measurements.
