No wonder the Americans have financial problems!
Guess they thought they’d never run out of money!!!
When NASA first planned to send up astronauts,
they quickly discovered that ball-point pens would not
work in zero gravity.
To combat the problem, NASA scientists spent a decade
and $1.2 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.
Confronted with the same problem, Canadians used a pencil!
