ink dropper works on the principal of air pressure.
when we fill ink inside the dropper we have to press it's bulb(upper,soft rubber portion),because of which the air inside the dropper is removed and low air pressure region is formed.
when we dip it in the ink,the space is filled with ink,which remains retained in it unless we press the bulb again.

∙ 11y agoAim: To observe air pressure act on ink dropper
Things needed: A dropper and water or an ink pot
method:
Press the bulb of the dropper
Lower the dropper in ink (or ink), keeping the bulb pressed
Now release the bulb
observation: water (or ink) is sucked up into the tube of the dropper.
Conclusion: When the bulb is pressed, air goes out of the dropper. When it is released in water, air pushes water into the dropper

What is the the best estimate of the capacity of a medicine dropper?
You're being flipping stoopid again - you don't mean the capacity of the dropper (wBTW - pr^2L) you mean the volume of a drop. The volume of a drop in technical terms is a drop.
Conclusion of the penny lab?

Why there is a small hole on the barrel of a nonretractable ball point pen?
Excellent question. Its there to allow air to enter the interior of the pen while the ink flows out. This ensures a smoothe and even flow of the liquid ink. It works on the same principal as why we poke two holes in a can of oil or juice. As the liquid flows out, the air flows in to replace the volume. Without this you get that gurgle that an inverted water bottle makes as it dispenses a cup of water. This hole also allows for the passage of air to flow out as the ink will expand a little when placed in sunlight or in a pocket. This prevents the ink from being pressured out the ball point end.

What is the difference between the ink dropper and the spray pump?
An ink dropper dispenses ink in small, precise amounts for detailed work, while a spray pump releases ink in a fine mist over a larger area. Ink droppers are best for controlled applications, while spray pumps are ideal for covering larger surfaces quickly.

A fountain pen can be filled by three means.1) Via an ink cartridge which is simply pushed onto the feeder for the fountain pen.2) Via a converter which is roughly the same as an ink cartridge except that it can be re-filled via a bottle of ink.3) Via a dropper straight into the body of the pen as in the LAMY 2000 Fountain Pen
