The 'space' pen !

Did you know that there exists a pen which can write in space ?  
Yes, the 'ordinary' ball pens that we use here don't work there; blame the gravity .

" The americans invented the space pen , spent millions
for the research . But ,wise Russians used the pencil
instead ! "


Should NASA be blamed for spending taxpayers money to
invent a pen that writes in space?

I would have, but they have reasons .  

First, the pencil is flammable! 

Second, the tip could break off, drifting in microgravity where
it might harm an astronaut or an equipment .

Third, a pencil costed NASA $ 128.89 a piece ; they needed to
find cheaper alternative.

This 'space' pen was invented by the Fischer Pen Company in
1965 .The ink cartiride is pressurised with nitrogen at 35 pounds
 per square inch.

Each pen costs $ 2.39 for NASA after a 40% discount .

Even Russia is using these pens now !

Hmmm, even you can own one for $ 50
