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
million 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.
The Russians used a pencil.
