When NASA first started sending up astronauts, they quickly discovered that ballpoint 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 temperature ranging from below freezing to over 300C.
The Russians used pencil.
