Water Vapor
Floating water droplets are called mist or spray. They are tiny droplets of water suspended in the air.
All water droplets in the air is different just like when they fall down.
That visible mass of water floating in the atmosphere is called a cloud. Clouds are made up of tiny water droplets or ice crystals that have condensed from the air.
Clouds are not just liquid water floating in the sky. They are actually made up of tiny water droplets or ice crystals that have condensed around tiny particles in the atmosphere.
Cloud droplets are made of liquid water, which is water vapor that condensed around a tiny condensation nuclei typically made of any number of different types of particulates or salts that are always floating around.
it is condensation floating in the sky
As far as I know mostly mist (small floating water droplets), small ice crystals and/or a number of suspended chemicals.
When you mix oil and water, the oil forms droplets known as emulsions. These droplets remain suspended in the water due to their differing densities and the lack of a strong attraction between oil and water molecules, which prevents the oil from floating to the top. Additionally, emulsifiers can help stabilize the mixture by surrounding the oil droplets and preventing them from coalescing.
A rainbow is the result of white sunlight being split up (refracted) into it's separate colours by the denser water droplets floating in air and then reflected back towards the source (the sun) by the surface of water droplets behind. The bow shape represents the perspective from the spectator, who has to be in between the source and the cloud of droplets to see a full rainbow.
Ice cream, like milk, is a colloidal mixture. It has tiny droplets of fat floating in water.
Rain occurs when droplets of water condensed on floating particles in the sky condense too much water, making the particle unable to float, so that the drop falls from the sky.
In space, water exists in the form of floating droplets or spheres due to the absence of gravity pulling it downwards. It can appear like floating blobs or balls due to surface tension and lack of buoyancy forces acting on it.
