Air pressure is what makes the ink change colors as it flows from the pen onto the paper. Without air pressure, the ink would remain colorless and, therefore, invisible on the paper.

Where is the fuel pressure release valve on the air intake manifold on a 1991 Ford Explorer?
It is at the top of the engine by the oil fill cap and near the air intake hoses
Compare air pressure on earth to air pressure on the moon?
The moon has no air pressure because the moon has no air.
How do you turn off the low tire light on a 2004 4Runner?
Fill the tires with the correct air pressure. ___________ Don't forget to check the spare too.
Why does the ink flow out of the fountain pen when the plane slowly gains height?
Pressure. That's the short answer. Back when people used fountain pens as a matter of course, aeroplane cabins had variable pressure throughout the flight. Pens, shampoos, potato chip bags, etc. expand, pop, or leak at high altitudes is because of low air pressure. The air inside a sealed container holds the pressure of the environment when it was closed. If this container travels up, to Denver or up in an aeroplane, the air pressure --barometric pressure-- of the environment becomes lower than it was closer to sea level. The container expands in dimensions or leaks in an attempt to equalize the pressure. These days people use ball point pens and they're pens don't leak. ;) Actually, these days commercial aeroplanes have better seals and climate control systems. However bleeding fountain pens may still be a problem because the pressure during the flight will decrease to that of a mountain city. According the Boeing (plane manufacturer) "The cabin air system in today's jetliners is designed to provide a safe, comfortable cabin environment at cruising altitudes that can reach upwards of 40,000 feet. At those altitudes, the cabin must be pressurized to enable passengers and crew to breathe normally. By government regulation, the cabin pressure cannot be less, at maximum cruise altitude, than the equivalent of outside air pressure at 8,000 feet." However, the container/luggage hold is outside the climate control system. Therefore, shampoo in your luggage may still ooze. Hint: puff the air out of the bottle when you pack, and put in a sealed ziplock-type bag in a luggage pocket.
Where is the highest air pressure?
air pressure is the highest near the earths surface
Why does the ink from a fountain pen spill out when you carry it in an aeroplane?
Air pressure
How do you remove chick tire pressure message?
fill the tires with air to the proper pressure.
How does air pressure cause wind to blow place to another?
If the air pressure lowers in a spot, the surrounding air tries to fill the hole.
How does a balloon expand?
when you fill a balloon with air the air makes pressure. the air pressure maximizes the balloon fabric allowing the balloon to expand.
How does air pressure cause wind to blow one place to another?
If the air pressure lowers in a spot, the surrounding air tries to fill the hole.
What do you use air pressure for or what is it good for?
It is good to fill the tires of your car.
Why does balloon become full when you blow air in it?
Once the air pressure inside the balloon is greater than the air pressure outside the surface it starts to fill. the higher the pressure inside the more the air acts against the inner rubber surface and the balloon gets harder. an empty balloon has the same air pressure inside and outside. Once you push any air in therefore you are starting to raise the air pressure inside.air molocules from you fill it up
What is an air fountain?
An air fountain is a device for producing a jet of water by the force of compressed air.
If you have a 200 liter receiver how much presurised air would it take to fill?
Depending on the pressure of air
How often should you fill your tire with air in the winter?
You should check the air pressure at least once a month.You should check the air pressure at least once a month.
