I bet a lot of you know about it ....I just wanted to post this for a young generation.
When NASA first started sending up astronauts, they quickly discovered the 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 300C. The Russians? They just used a pencil.
Viva la brain!
hope i was successful with a picture
