Cloud is an element in Earth Editor. Cloud has reversed gravity, which means it is pulled by white holes and pushed by black holes. Cloud is pulled by the other elements, but the particles stay a certain distance from them. When any element hits cloud, the cloud turns into water. When cloud gets far enough from black holes or close enough to white holes, it has normal gravity, causing it to form rings which are usually perfect circles. Cloud is comparable to a fusion of gas and snow from Powder Game. Placing wall around the cloud will have it move outwards from the center of gravity.
