FOCUSSING ON PROBLEM

When NASA began the launch of astronauts into space, they found out that the
pens wouldn't work at zero gravity (ink won't flow down to the writing
surface).

To solve this problem, it took them one decade and $12 million. They
developed a pen that worked at zero gravity, upside down, underwater, in
practically any surface including crystal and in a temperature range from
below freezing to over 300 degrees C.

And what did the Russians do...??

They used a Pencil!!!
