APOD 4.8 (Time Lapse Clouds and Sky Over the Canary Islands)

I chose this one because clouds behaving like water is a very rare and surreal phenomenon, partially because clouds are so high above the ground that we are rarely at a good height for this to happen, and partially because we tend to think of clouds as amorphous gases instead of low density water.  The clouds on mountaintops behave just like water on beaches, ocean floors, or even the tops of waterfalls!
