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.

Why there is zero gravity in space?

Actually there is gravity (non-zero gravity) in space. You just don't feel it when you are in free fall. For more details, read some articles (for example, in the Wikipedia) about "free fall".


Is zero gravity possible?

Zero gravity, also known as microgravity, occurs when an object is in freefall and experiences an apparent weightlessness. This is commonly observed in space environments such as the International Space Station. While true zero gravity does not exist in a gravitational field, there are environments in which the effects of gravity are minimal enough to create the sensation of weightlessness.


Did the zero gravity pen change any when it is used on earth?

The zero gravity pen has never been changed or updated because it is almost flawless and nobody has anything to add to it.AnswerThe zero gravity pen relies on the polarity of water in the ink to induce the capillary action to draw ink down to the ball of the pen. Since this doesn't rely on gravity, there is no change when the pen is used on earth.


Does air exist in zero gravity?

If you introduce air into a space where gravity is zero, then air exists there. A current example is the inside of the International Space Station, where the crew live and work in a "shirtsleeve environment" that includes air, pressure, and warmth, but they also live and work in an environment of weightlessness, or what is popularly but erroneously called "zero gravity".
