Physics/Pens and Defying Physics?


Does the ballpoint pen match current theories of physics, or does it defy pressure, conservation of mass, etc.?

I have received responses from forums that suggest that the pen makes a thin line and thus doesn’t use much ink.

Maybe this is just crazy.

Maybe the ball point of the pen makes more ink by spinning ink?

The pen I was using does appear to eventually run out of ink, but it seemed to take way too long to run it out.

I don't know of anything that can defy the laws of physics, certainly not a ball point pen.  Ball point pen cartridges are filled with a certain amount of ink and that's it.  Some cartridges are bigger than others so it's hard to compare how long they last.
