The air column in the end of the tube obviously got shorter when the bottle was squeezed.Can you estimate by what percent it got shorter? What was its length when the squeeze was on, as a percent of its length when the squeeze was relaxed?
****
You can not estimate it because you do not know the total length of the tube.

Paperclips have been placed around the curve, about half on the inside and about half on the outside of the curve.
How could you use this picture to estimate the percents requested above?
****
You can estimate the percent that it moved by using the paperclips as measuring tools.

You can see the tube and the column. So you can estimate one as a percent of the other.
