ELI5: Why is it that waterdrops can't be bigger? What's stoping water from forming like the size of a golfball or even bigger?

Water drops are held together by surface tensions, and the hydrogen bridges that create it.

Whichever force is applied to the drop will "battle" with surface tension. If the force is bigger than the tension, the water drop breaks. If not, the water drop stays together.

Here on earth gravity is the most common force, when the drop is somewhere on the ground, or dripping off something.

In space, for example on the ISS drops of water can be huge because gravity doesn't apply anymore.
