Because the air pressure is lower on high altitudes. Envision it; there's less air pressing down the higher you get.
Now, the ink inside the pen is still 'used to' lower altitudes and higher pressures, so the pressure inside the pen is high as well. It stays like this as you ascend and the air pressure gets lower. Eventually the pressure inside is so much higher than the pressure outside that the pen starts leaking.
You can see the same with bags of crisps (puff up as you get higher) and deep sea fish that are brought to the surface (sometimes blow up altogether). It's also responsible for painful ears in a descending airplane - the outside pressure gets higher rapidly and your ears aren't ready for it yet.
A fountain pen might leak at higher altitudes due to changes in air pressure. As the altitude increases, the air pressure decreases, causing the ink inside the pen to flow more easily or even leak out. This can result in messy ink spills.
a fountain pen starts leaking at higher altitudes because the difference in air pressure is less than it is on the ground so the ink flows quicker so not exactly a leak rather you not being able to keep up with the flow from the cartridge.
A fountain pen may leak at higher altitudes due to changes in air pressure affecting the ink flow within the pen. The lower air pressure can cause the ink to expand and contract more, leading to potential leaks through the nib or cartridge. It is advisable to store fountain pens in a horizontal position or with the nib pointing upward to minimize the risk of leaking.
well it depends on the lucrative amount of spaciousness through the tube of ink. Also if the tube is full of ink then yes it would work but if the tube is not full then the ink may or may not come though so its a 70% chance of it working based on my scientific calculations at the department of NASA.
Lie down and write with a ball point pen upside down. after a while the pen wont work because it needs the ink to fall down to the ball point. there is no gravity in space there fore the ink will just float it wont fall Edit: why not use a pencil?
I don't know this as a fact, but this makes sense to me: Fountain pens work on a capillary action system, with only tiny amounts of force applied to the ink to make it go down to the nib. When you go up to a high altitude, suddenly pressure decreases, and the pressure in the pen relative to the outside becomes much higher. Seeking to equalize pressure, the ink starts coming out faster.
A fountain pen may leak at high altitudes due to changes in air pressure. As the air pressure decreases at higher altitudes, the pressure inside the pen may become greater than the external pressure, causing ink to leak out. Additionally, fluctuations in temperature can also affect the viscosity of the ink, leading to potential leaks.
Air pressure is forcing the ink out of the tube.

The "ink" that is leaking is not toxic nor combustible, it will not explode when it's spilled, however it's still better to replace the LCD screen.
The Epson 69 High Capacity Black Ink Cartridge holds 13 ml of ink.
"HP has an XL series of ink cartridge, that has capability of producing 750 pages. These high yield black ink cartridges will help prolong intervals between ink purchases."
It's called "ink". There isn't a special magical kind of ink that's used on all high school diplomas and nothing else.
Brother ink is a quality brand for ink cartridges. Brother ink is slightly expensive, but it isn't a waste of money. There is other brands of high quality ink brands.
