When NASA first started sending astronauts up,
they quicky discovered that
ball pens won’t work in zero gravity.
.
To overcome this problem
NASA spent a decade
and 15 million dollars to develop a pen
that writes in
zero gravity,
upside down,
under water,
virtually in any condition on any surface
including glass
and
at temperature ranging
from below freezing to 300 degree celsius.

The Russians used a pencil.
