This sorta reminds me of a story I heard some time ago(it may be just a myth, but it's nonetheless interesting). Upon reaching micro-gravity astronauts and people at NASA noticed that the regular pen can't write in such condition, due to the lack of gravity that pushes the ink down.
After a couple of years and good few million dollars later, they invented a special pen that could write in the most vicious enviroments.
Russian cosmonauts faced this issue too. They used pencils!
