When NASA first started sending up astronauts, they quickly discovered that ball-point pens
would not work in zero gravity.
To combat this problem, NASA scientists spent a decade and $12 million developing a pen that
writes in zero gravity, upside down, on almost any surface including glass and at temperatures
ranging from below freezing to over 300 C.


The Russians used a pencil.
