When NASA first started sending up astronauts, they quickly|
discovered that ballpoint pens would not work in 0 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 used a pencil.
