Observations in high spatial and temporal resolution in the seeing free environment of space have cast new light on prominences revealing a huge range of dynamic phenomena. One of the most interesting of these is that of the magnetic Rayleigh-Taylor instability creating plumes that rise through the body of the prominence. In this talk I will present my numerical work studying the formation and evolution of the magnetic Rayleigh-Taylor instability in a prominence. By studying the compression of the prominence material as the plume rose, it was possible to develop a model that could estimate the plasma beta (ratio of gas to magnetic pressure) of the prominence. Relating this back to actual prominence observations, I hope to show that the presence of the Rayleigh-Taylor plumes provides a powerful diagnostic tool for understanding the plasma conditions of the prominence itself.
