Ball Point Pens
When NASA started sending astronauts into space they quickly discovered that ball-point pens would not work in zero gravity.
To combat this problem, Congress approved a program and NASA scientists spent a decade and over $165 million developing a pen that writes in zero gravity, upside down, on almost any surface and at temperatures ranging from below freezing to over 300 C.
The Russians used a pencil!
Your taxes are due again in April.
(I'll bet ,ost astronautscontinued writing with their pencils, don't you think so, Doc!)
