Your 'measuring atmospheric pressure' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

** How does the system behave and how does it 'feel'? **
When the bottle is squeezed, the vertical column rises depending on how much force is exerted. The pressure gauge also moves, shortening the air column, but much less than the vertical tube.
** Length of the air column in units of your measuring device: **
single reduced; easiest to read for this size.
** 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. **

Using the single reduced ruler, I placed one end at the capped end of the tube and read where the meniscus was.
** 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. **
