Answer

Water does not run out of a dropper unless it’s rubber bulb is pressed because the pressure inside the dropper is same as the atmospheric pressure when the rubber bulb is not pressed. But, when we press the rubber bulb the pressure inside the dropper increases and hence the water flows out.
