During the initial space
flights, Nasa discovered that biro pens didn’t work under zero gravity
conditions. To beat the problem, Nasa spent 6 years and $2 million in designing
a pen for use in space. The pen would work under zero gravity conditions due to
the pressurized ink inside, it would work under sub zero conditions, underwater,
on glass and virtually any surface known to man. The Russians used a pencil.
