We present a model based on the results of nearly 10 years of the study of microvariability in a sample of Blazars. The model is based on the facts that: 1) The variations do not show the characteristics of random noise, 2) The variations are not periodic, 3) The variations are best described as stochastically generated pulses of varying amplitude and durations. We show microvariability curves dissected with this interpretation in mind, and propose a theoretical underpinning for this model based on shocks encountering turbulent cells and cooling via synchrotron radiation. We show microvariations (and the lack of them) can be understood in terms of this model. We also describe an observational test to investigate the validity of this model.
