When NASA started sending astronauts into space, 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.
