Physicists create supernova in a jar (w/ Video): "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."
