Too complicated

Here something interesting..

When the space organization NASA first started sending up astronauts they discovered ballpoint pens would not work in zero gravity. To solve the problem, NASA scientists spent ten years and $12 billion to develop a pen that would write in zero gravity, upside down, under water, on all types of surface, and at temperatures ranging from below freezing to 300 Celsius. The Russians used a pencil.

Moral : Sometimes things are simpler that we think..
