Conclusion

    We accomplished our goal, which was to better understand the dynamics of a milk splash, in this experiment.  By using different colored milk we could easily see the special properties of a splash.  The first conclusion we came to at the end of this experiment was a milk drop remains very spherical in shape while entering the milk (fig.1), and the surface tension of the drop is is broken only after the drop has entered the static milk surface more than halfway (fig. 2).  Second, we discovered that the drop of milk stays on the inside of the crater formed in the static milk's surface.  This is very interesting, as the dropped milk still hasn't mixed with the static milk.  The dropped milk stays on the inside of the crater all the way up to the point when the crater collapses on itself and forms a column of milk (fig. 3).  When this happens, the milk that was previously inside the crater still hasn't mixed, and is now at the peak of the column.  Eventually, a droplet breaks off the column.  What's interesting about this droplet is the fact that it contains all the milk that was dropped into the static milk (fig. 4).  Basically, the milk dropped into the static milk is separated all around the splash and then perfectly reforms into a sphere containing the same milk at the end of the splash sequence.  The symmetry and perfection in a splash that allows this to happen is amazing.
