Nigerian is smarter than them all !!!

When NASA first started sending

up astronauts, they quickly discovered that ballpoint pens would
...not work

in zero gravity.
To combat the problem, NASA scientists spent a
decade and


$12 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°C.

The Nigerians used a pencil instead  !!!!!
