The deformation radius gives an idea of how much the front will spread before reaching a stable state. In the subsequent section, we discuss how well these theoretical predictions align with the results of our laboratory experiments.

In order to collect data from our experiment, we tracked using video processing software buoyant particles at the surface of the fluid, as well as particles with density in between that of the two fluids which sat just above the frontal boundary. The shape of the front, although relatively stable, did vary slightly throughout the course of the experiment, as can be seen from the following images.
