The opening of a dropper is very narrow as the pressure generated by an assigned force is inversely proportionate to the region of the exterior on which the power performs. Thus the pressure should be equal if anyone wants to use a dropper. For instance, if we fill the dropper it leaves some drop space empty to create the equal pressure.
