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 on 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. The time stamp shown is relative to the time at which the can was removed, allowing the two fluids to meet.

Initially, the shape of the front resembles a Gaussian, with a wide sloping surface and flat top. As the experiment progresses, the front gradually becomes smaller in size and its sides flatten, leaving a sharp peak in the center. While the fluid is not in perfect hydrostatic balance, otherwise the front would last forever, it is stable enough that we assume hydrostatic balance as we did in our theoretical calculations.
