A vertical tube of viscous solution contains stable reactants for the Iodate Arsenous Acid reaction. An indicator makes the solution red. Reaction is triggered at the base of a small tube at the bottom, leading to a growing plume that sheds accelerating vortex rings. No fluid is injected: all the buoyancy is created by the reaction itself.

This image shows a pair of successive accelerating vortex rings launched by the plume.

The process is analogous to the nuclear deflagration leading to the detonation of a type Ia supernova.

A plume driven by buoyancy which is being created by a chemical reaction. The plume accelerates and sheds accelerating smoke ring vortices. The process is analogous to the detonation of a type Ia supernova.

This montage shows the effect of changing glycerine concentration and hence viscosity.
