I was a little confused on this lab I hope I completed this lab correct.

When you squeeze the bottle the water rises in the vertical tube and the water preesure tube will shorten the air column. The harder you squeeze the higher the water rises and the shorter the air column becomes.

I picked the original ruler to have an accurate measurment.

I measured the length of the column with a ruler I taped one of the ends to the column and then measured the column to get an accurate reading.

I filled the water up to the water line and then squeezed the bottle and measured the meniscus and the water line mark. Then I repeated this 4 more times.
