When astronauts started to explore the reaches of outer-space, Paul Fisher realized that no existing pen could perform in its zero-gravity vacuum and temperature extremes. His common sense approach and practical experiments resulted in the invention of the sealed-pressurized Fisher AG7 "Anti-Gravity" Space Pen. After rigorous testing, NASA selected the Fisher Space Pen for use on all of the Apollo missions. The Fisher Anti-Gravity Space Pen is still used on all manned space flights today! |
