We present the first evidence for spatio-temporal merging dynamics in thin gap electroless deposition experiments. The influence of both the gap thickness and the buoyancy forces on these phenomena is analyzed. The occurrence of this reverse cascading dynamical process is discussed in terms of the interaction of two counter rotating buoyancy driven convection rolls.
