gerbil runner Posted March 24, 2004 Share Posted March 24, 2004 YOUR TAX DOLLARS When NASA first started sending up astronauts, they quickly discovered that ball-point pens would not work in zero gravity. To combat this problem, NASA scientists spent a decade and $12 billion developing a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to over 300° C. The Russians use a pencil. Quote Link to comment Share on other sites More sharing options...
