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.

Why do fountain pens leak at higher altitudes?
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.
Does an ink pen work in space?
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.
Why don't ballpoint pens work in space?
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?
Why fountain pens are not used in space?
Fountain pens depend on gravity to pull the ink down to the nib. In Zero gravity, they don't work.
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.
Why does a fountain pen start leaking at high altitude?
When taken to high altitudes, the outside pressure drops causing the ink to flow out. Some models do not leak. Equalize the pressure by taking the cap off.
Why while flying in an airplane you find your pilot pen start leaking?
Air pressure is forcing the ink out of the tube.
Who shoots out cloud of ink to hide?
a squid with a leaking pen
Why does a fountain pen leak at high altitude?
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.
Why does lcd readout turn partially black on radio looks almost like it was smashed or ink is leaking?
L.iquid C.rystal D.isplay broken and is leaking it fluids
The cause of leaking laptop screen?
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.
How much ink does the Epson 69 High Capacity Black Ink Cartridge hold?
The Epson 69 High Capacity Black Ink Cartridge holds 13 ml of ink.
Why do Bic pens have a hole in the middle?
If it was completely airtight, then the pressure inside would drop, preventing ink flow. Placing a hole in the middle equalises the pressure and controls the flow of ink. The hole, basically, stops the pen from leaking ink.
Does HP make a high yield black ink cartridge?
"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."
Why ink spil out from pen in the aero plane?
Because as altitude increases, air pressure decreases. As the plane rises, the air pressure inside the pen is higher than outside it causing the ink to spill out.
What is the ink use on a high school diploma call?
It's called "ink". There isn't a special magical kind of ink that's used on all high school diplomas and nothing else.
Is Brother ink a quality brand for ink cartridges?
