In this paper we conduct a simple experiment wherein we create a wave within a circular container and analyse the interference patterns generated by the reflections from the boundary. In doing so we observe constructive interference in positions in space where our current wave theory predicts noise. This result demonstrates that in the particular situation presented here, the velocities of a wave before and after reflection from a solid boundary, are unequal. Analysing these peculiar events, I present a rebuttal to the Special Theory of Relativity by the method of reductio ad absurdum.
