How Does A Fontain Pen Work?
As a fountain pen is dragged along a piece of paper, ink flows through the feed (the part connecting the ink tank and the nib) and ink molecules are pulled onto the paper one after the other. Air is let in through the slit on the nib. Thus the ink continues to flow as long as the pen is in contact with the paper. When the pen is lifted, ink molecules do not experience any pull and hence do not fall off the pen.
