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 almost any surface including glass and at temperatures ranging from below freezing to 300°C.
They are still scratching their heads.


The Russians used a pencil.

Probably more of an 'Ouch' Tony.

[tonyav]

Another groan, lol

For Gawds sake will anyone twig on that this is a "JOKE SECTION?)
