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'? **
By squeezing the bottle and thus increasing the airpressure inside of it - the water in the vertical tube rises a proportionalte amount of the decrease in air culomn length.
** Length of the air column in units of your measuring device: **
I will use mm at zero reduction and interpolate - my eyesight is not good enough to be confident about reading such small graduations without the use of vernier.
** 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. **
201 mm
I set the capped end of the air column at 400mm on my scale and read the meniscus at 199mm.
** 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. **

These are meniscus readings before and after each squeeze to the first mark on the vertical tube
