Book 20, Question 96
Can You Walk Inside a Cloud?
Yes, you can walk inside a cloud! A cloud is just a mass of tiny water droplets, the same as fog. So when a cloud rolls over a mountain trail, you are inside it.
More fun facts

- A cloud is made of tiny water droplets, each about 0.01 millimeter wide.
