Chocolate fountains are popular features at special events. But why do they never
use white chocolate? Would they ~work with water? And why, when the chocolate falls,
does it fall slightly inwards?

In this most delectable of studies, we investigate the trade-off between accuracy
and simplicity in models used by commercial chocolatiers. In different geometries
of the fountain, we solve the governing equations, mostly analytically, and compare
these results with observations from our own fountain experiments. We find that,
with some limitations, our models are in fact good for a number of non-Newtonian
fluid problems. Marshmallows are, sadly, not provided.
