The smallest scale is a laboratory experiment. The intermediate scale is a rocket-borne space experiment and the largest is an exploding star. In each case, deceleration creates a situation that is unstable to the Rayleigh-Taylor instability. The similarity exists in the spatial and in the Fourier domains; that is, not only are there obvious spatial similarities but the power spectra of the two phenomena are also nearly identical. The data compare favorably to published simulations. %K Rayleigh-Taylor Instability %K Decelerating Fluid %K Exploding Star %K Active Experiment %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=16373
