Water does not run out of a dropper unless the rubber bulb is pressed because when the bulb is squeezed, it creates a vacuum inside the dropper. This vacuum pressure forces the water to be sucked up into the dropper. When the pressure is released by letting go of the bulb, the water remains in the dropper due to the lack of pressure forcing it out.

How do you make a home made eye dropper?
To make a homemade eye dropper, you can sterilize a glass dropper or a clean, empty plastic dropper bottle. Boil the glass dropper in water for 10 minutes or wash the plastic dropper bottle with soap and hot water. Once dry, use it to dispense the desired volumes. Remember to store the dropper in a clean, dry place when not in use.
When water in a beaker is heated bubbles come out to the surface why?
When a droper is dipped into water and its bulb is pressed air bubbles seems to occur in water because the dropper was filled with air before it was dipped in water and when we press the bulb air comes out forming air bubbles and the space is filled with water .
What happens if ruber and water meet?
When rubber and water meet, the rubber can absorb some of the water due to its hydrophobic nature. However, depending on the type of rubber, prolonged exposure to water can cause deterioration or swelling of the rubber material over time. This can impact the rubber's properties and performance.

Why does the qater in a dropper not come out unless rubber bulb is pressed?
The water in a dropper does not come out until the rubber bulb is pressed because of the difference in air pressure. When the bulb is in its relaxed state, the pressure inside the dropper is lower than the atmospheric pressure, keeping the liquid inside. Pressing the bulb increases the internal pressure, forcing the liquid out through the nozzle. When the bulb is released, the pressure equalizes, preventing the water from flowing back in.
How does the ink dropper works?
ink dropper works on the principal of air pressure. when we fill ink inside the dropper we have to press it's bulb(upper,soft rubber portion),because of which the air inside the dropper is removed and low air pressure region is formed. when we dip it in the ink,the space is filled with ink,which remains retained in it unless we press the bulb again.
Why does the water gets filled in the dropper when it is pressed and released in water?
because of the atmospheric preesure
Why does not liquid run out of dropper unless pressed?
Water doesn't come out because the water cannot be replaced by air when the water is squeezed out. This is because the water would spill out, but air pressure is in the way If the hole at the end of the dropper was bigger, then the water could spill out. That is why the water spills out when you pour a drink for yourself. The water spills out , and at the same time air is spilling into the bottle.
