the pen dilemma

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 billion 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.

    Don’t know about you but a pencil works better in any temperature. Plus, how many times do you make a mistake using an ink pen? For 12 billion dollars, you can buy a lot of pencils.

      Of course a pencil works better! Can you imagine hi-tech graphite? Guess it’s not much different than hi-tech ink. But it doesn’t cost as much.
