Placing ink on paper at just the right rate
* Not all pens, of course, are good pens. Some pens need to be shaken more violently than a new bottle of ink in order to get anything to come out. Other pens dribble ink all over the paper. These poor pens make me appreciate good pens all the more. * At work, I am currently using a "Papermate Pro-Fit." It's not too bad. I like that it's mechanical.* One exciting thing about mechanical pens is that you can use their spring to launch them from a table several inches into the air. This is a great cure for boredom in a college class.* Also in college, I used to do homework outside, even in the winter. I think that pen ink flows less easily when it is cold.
