Rayleigh-Taylor instability on a viscous sphere initially perturbed with a spherical harmonic 𝑌83 grows in a radial gravitational field. As time progresses, the classical signature of mushroom-like structures is observed all around the globe. This is a primary example of mushroom cloud or smoke formation, and therefore, we call them Rayleigh's mushrooms.
