The rise of water in the dropper is due to atmospheric pressure.
When the bulb of a dropper is pressed, the pressure inside the dropper decreases and this causes the water to go inside the dropper.

it happens because when we press the bulb of the dropper, the air is pushed out of it, and when we place it's nozzle in water, there is a area of low pressure inside the bulb of the dropper, and high pressure in the water, so, the water travels up to the area of low pressure from a area of higher pressure
