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'? **
the water rises very fast in the vertical tube but moves a very small amount in the pressure tube. bottle is slightly hard to squeeze but not too bad.
** Length of the air column in units of your measuring device: **
I chose the reduction where 1 cm equals .65 actual cm.
I chose this because it seems to be just the right size to work with. The happy medium.
** 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. **
44.5 cm
i taped 2 of the measuring devices together and aligned them so that it was one continuos ruler. the readings started at the 1 cm line and went to the 45.5 line. i then subtracted 1 cm from the total.
** 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. **

30.3, 30.6
30.4, 30.6
30.4, 30.6

This gives me an average of my readings.
