We explore the dynamics of low to moderately viscous (20-100 cSt) silicone drops bouncing on a vertically vibrating bath of the same fluid. The drops exhibit complex spatiotemporal dynamics, including chaotic motion, the assembly of multiple drops into pulsing lattice structures, and self-propelled ‘walkers’ that mimic quantum behavior.  High-speed imaging is used to track drop deformation and center-of-mass motion during impact. We present preliminary results from our undergraduate nonlinear dynamics laboratory and discuss future directions of this work.
