Did you know that clouds float upwards when there is gravity but feathers can't?
A cloud is made out of jillions of tiny water droplets. Each droplet is pulled toward the earth just like anything else. But tiny particles have lots more surface area compared to their weight. That gives a lot of friction in moving through air. Because of that, they fall very slowly. In addition, upward- blowing drafts of air keep these cloud droplets from falling to the ground. If you have watched clouds, you have noticed that they are always changing in shape. They are always moving in those gusty winds that hold them up there.
