When NASA first started sending up astronauts, they quickly
discovered that ballpoint pens would not work in zero gravity.


To combat the problem, NASA scientists spent a decade and
$12 Billion to develop a pen that writes in zero gravity, upside
down, underwater, on almost any surface including glass and
at temperatures ranging from below freezing to 300C.
