How does a space pen work?
The space pen works in numerous conditions: upside down, from -50oF to 400oF, in a vacuum, and underwater. The pressurized nitrogen also prevents the air and ink from mixing within the pen so that the ink does not evaporate before use. When the ballpoint moves, the gelatinous ink within the pen becomes liquid.
Did NASA invent a pen for space?
