A large concentration of tiny water droplets is called a cloud. Clouds are formed from water vapor that condense into clouds.
If your question is what I think it's trying to state, the answer is evaporation.
A collection of water droplets suspended in the air is called a cloud. If the collection of water droplets is close to the ground it is called fog.
On land a large body of permanent ice is a glacier; in the water this is an iceberg.
The clouds floating overhead contain water vapor and cloud droplets, which are small drops of condensed water. These droplets are way too small to fall as precipitation, but they are large enough to form visible clouds. Water is continually evaporating andcondensing in the sky. If you look closely at a cloud you can see some parts disappearing (evaporating) while other parts are growing (condensation). Most of the condensed water in clouds does not fall as precipitation because their fall speed is not large enough to overcome updrafts which support the clouds. For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation. This is not a trivial task since millions of cloud droplets are required to produce a single raindrop. A more efficient mechanism (known as the Bergeron-Findeisen process) for producing a precipitation-sized drop is through a process which leads to the rapid growth of ice crystals at the expense of the water vapor present in a cloud. These crystals may fall as snow, or melt and fall as rain.
The air needs to be cooled, the amount depending on how much water vapour is in it. When it's cooled sufficiently the water vapour will condense on solid things as water, or become very small droplets (fog/cloud). When this happens in the early mornings we call it dew, and the temperature at which the water will condense is known as the dewpoint.

A cloud.
Simple answer: They don't. Clouds ARE water - tiny, tiny droplets of water just like fog. If colder air moves into a cloud, it causes there to be even more water droplets forming. When the droplets get close enough together, they start touching and turning themselves into even larger droplets. Then the "even larger" water droplets touch, and make water drops . . . at some point in this process, the water droplets grow large enough that they are too heavy to stay where they are, and then they fall to the ground. This falling to the ground is what we call, "Rain".

simple answer osmosis defined as the diffusion of water from a area of high concentration to a area of low concentration.
The water droplets are the result of the humidity in the air colling down and condensing on the outside of the glass. When water evaporates it turns into water vapor or steam we call the amount of water vapor in the air humidity. condensation is the reverse of evaporation and is also responsible for rain.
the process is call OSMOSIS.
Osmosis
This is one of many parts of the water cycle. water needs to condense (turn into a cloud) Then it will precipitate (a fancy word for rain ect.) or as you call them ,water droplets. By the way if you are not in the fifth grade (below it ) do not worry it is simple fifth grade science
