When push squeeze the bulb (this is the force), you exert pressure EVERYWHERE in the dropper, (upwards, downwards, etc), so the liquid in the medicine dropper it forced to come out since in the increase in pressure is applied everywhere,
This is known as pascal's principle

OK it's kinda like this , the surface tension of the fluid prevents it from obeying gravity because of the small size of the droppers opening.when the pressure on the orifice (tiny opening ) is increased by either a taller column of fluid above it or more air pressure (you squeeze the bulb) the pressure on the fluid overcomes the surface tension and drops come out the dropper.
