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 almostany surface including glass and at temperatures ranging from below freezing to 300 C. The Russians used a pencil.
