True Scifi Story
During the initial space flights, NASA discovered that biro pens didnât work under zero gravity conditions.
To beat the problem, the American space agency spent 6 years and $95 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.
On the other hand, in response to the same challenge, the cash-strapped Soviets used a pencil.
