While just about any product manufactured these days will call itself “revolutionary”, the Fisher Space Pens don’t need to flaunt the fact that they are incredibly innovative by any standards. Their engineers invented an ink they called thixotropic semisolid ink that was only liquefied by the movement of the rolling ball. Each cartridge was pressurized using nitrogen, taking the need for gravity out of the equation. The result was the first pen that could write upside down, underwater, and, of course, out in the zero gravity of space. NASA immediately got onboard and Fisher Space Pens were the go-to writing instruments on the 1968 Apollo 7 mission.
