That is just entirely wrong. If the bouncing drop model can be considered an experiment at all, it is an experiment about certain macroscopic behavior. It is a fluid dynamics experiment, not a quantum experiment.
But the broader point is that there can’t be an experiment that proves pilot wave theory over standard QM even in principle, because they make exactly the same predictions about observable outcomes. (*barring what is called quantum non-equilibrium in the pilot wave literature, which has nothing to do with the bouncing drop model)
