Typically, clouds are suspended thousands of feet in the air and we fly through them in planes. But can we actually touch them without being in a plane?
Well, the simple answer is yes, but we will get into it.
Clouds look like they would be fluffy and fun to play in, but they are actually made of trillions "cloud droplets". These are very tiny particles of water which make up clouds and are usually about 20 microns or 0.02 Millimeters in size. For reference, raindrops are usually 1 or 2 mm but can be as large as 4 - 5 mm, so this is at least 100 times smaller than a raindrop. Nonetheless, if you were to be able to touch a cloud, it wouldn't really feel like anything, just a little wet.
However, what if I said most people have touched a cloud before. Although it is slightly different with where it forms, fog is technically considered a cloud, just not airborne. Fog only forms on the ground and the feeling of fog is usually just damp. Unfortunately, it does not feel like cotton balls or cotton candy, but most people have technically touched a cloud before.
Although this is in a forest, it is a good example of what fog looks like from above. It appears to be a normal cloud, just on the ground
If you wanted to touch an airborne cloud, the best way to do this is either skydiving or in a hot air balloon, though I would not want to be stuck in a cloud while in a hot air balloon.
Either way, if you have ever been in fog, you have been in a cloud and you can technically touch it.
