Fisher Lacquer Bullet Space Pen

Fisher Space developed, in 1966, the first anti-gravity writing instrument, which has been in use on all manned space flights since Apollo 7 in 1968. Fisher created a revolutionary, hermetically sealed and pressurized refill using thixotropic™ ink in a semisolid state that would not rely on gravity, nor leak or dry out, and would liquefy and flow only when needed. Fisher Space Pens write upside down, underwater, through grease, freezing cold and scorching heat.
