The Short Answer
[Wikipedia says](_URL_0_): > Mushroom clouds result from the sudden formation of a large volume of lower-density gases at any altitude, causing a Rayleigh–Taylor instability. The buoyant mass of gas rises rapidly, resulting in turbulent vortices curling downward around its edges, forming a temporary vortex ring that draws up a central column, possibly with smoke, debris, or/and condensed water vapor to form the "mushroom stem". So in ELI5-terms: the hot gas resulting from the explosion creates an updraft which pulls debris/dust from the ground up and forms a vortext at the top.
