text: how thick are the thickest clouds ??? how thick are the thickest clouds?  not in terms of visiblity, but as far as texture.  if you put your hand one of those big white, thick thunderstorm clouds would it feel like jello or something like that in terms of thickness?  i also wanted to know this ever since i was a kid.   thanks! :) usually clouds have no thickness. it's all in a matter of knowing how air moisture feels to you. basically a cloud is a floating piece of condensated pond moisture.
