The Pencil Is Mightier Than The Sword

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.

The Russians used a pencil.

Saw this on facebook and just had to share


  1. The thing is, they need not have bothered. A pen works perfectly well in zero gravity. And they cannot use pencils, because the tips break off. That bit is an out and out fallacy.

    People are funny.
