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 300 Celsius.
Confronted with the same problem, the Israelis used a
pencil......lol
