Experiments with a laser trigger and water drops. Two flashes (1 almost perpendicular to the camera above the water level (shading the wave edges) and one below the water level (providing the color for field distortions).

Experiments with a laser trigger and water drops. One flash almost perpendicular to the camera above the water level (shading the wave edges). The water is acidic and the drop is basic and includes a pH indicator (yellow if acidic, pink if basic). You can see the diffusion and interactions of the mixing water from the drop and the rest of the water. I really need to get back and do these well.
