this pen was invented for use in space
There is a pen appropriately named the Space Pen (also known as Zero Gravity Pen) produced by the Fisher Space Pen Company. The pen itself is also advertised to write underwater.
Paul Fisher, an American inventor and politician, invented the space pen in 1965.
The astronauts use space pen to write in space or zero gravity.The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is claimed to write in zero gravity, upside down, underwater, over wet and greasy paper, at any angle, and in extreme temperature ranges.The Fisher Space Pen was invented by American industrialist and pen manufacturer Paul C. Fisher and is manufactured in Boulder City, Nevada, USA. Paul C. Fisher first patented the AG7 "anti gravity" pen in 1965. Pens claiming some or all of the same abilities have also appeared on the market from other manufacturers.
The zero gravity pen was originally used in space so astronauts wouldn't have to find a pen for example if the zero gravity pen floats then the astronauts would be able to see where a pen is because if the pen did not float then if one of the astronauts needed to write something down they would have to write.

It paid millions of money after this space pen.
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper

Gravity is what forces an ink pen to work. The ink flows downward due to gravity. In an area without gravity (like space) the pen wouldn't work.
a pen
during the space race back in 1960's ,nasa was faced with a major problem . the astronaut needed a pen that would write in the space vacum.nasa went to work.at a cost of$1.5millons .the developed a "astronaut pen".it enjoyed the minor succes on the commercial market. the Russians were faced with the same dilemma they used a pencil a fisher space pen is used
