answer: due to atmospheric pressure
explanation: When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles and creates the vacuum in the bulb. Once we release the pressure on the bulb, water gets filled in the dropper because the pressure in water is more than the pressure in the bulb so water moves from the higher pressure to the lower pressure.
