The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is claimed to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in very wide temperature range.
The Fisher Space Pen was invented by American industrialist and pen manufacturer Paul C. Fisher and is manufactured in Boulder City, Nevada, United States of America. Paul C. Fisher first patented the AG7 "anti gravity" pen in 1965. Pens claiming some or all of the same abilities have also appeared on the market from other manufacturers.

Famous quotes containing the words space and/or pen:
“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
“Translate a book a dozen times from one language to another, and what becomes of its style? Most books would be worn out and disappear in this ordeal. The pen which wrote it is soon destroyed, but the poem survives.”
—Henry David Thoreau (1817–1862)
