When I was a kid I wondered what it was like to touch a cloud. I figured they were roughly somewhere between the size of a car and a house. I thought they would feel soft like bubbles and be slightly cooler than the air around them. It was a really big letdown the first time I flew through a cloud in an airplane. “This is the inside of a cloud? I can’t see anything!”
