  We apply superstatistical techniques to an experimental time series of
measured transient current through a thin Aluminium-PMMA-Aluminium film. We
show that in good approximation the current can be approximated by local
Gaussian processes with fluctuating variance. The marginal density exhibits
`fat tails' and is well modelled by a superstatistical model. Our techniques
can be generally applied to other short time series as well.
