[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
300°C
