When NASA first started sending astronauts into space, they realised that ball-point pens wouldn't work in zero gravity.
A million dollar investment and two years of testing resulted in a pen that could write in space, upside-down, on almost any surface and at temperatures from sub-zero to 300 degrees.
When confronted with the same problem, the Russians took a pencil.
