Zero Gravity
When NASA started sending up astronauts, they quickly
discovered that ball-point pens would not work in zero gravity. To
combat this problem, NASA scientists spent a decade and $12 billion
developing a pen that writes in zero gravity, upside-down, on almost
any surface including glass and at temperatures ranging from below
freezing to over 300 C.
The Russians used a pencil. Your taxes are due again--enjoy paying
them.
