Giant Bubble

We made these giant soap films at the Children’s Museum. Due to surface tension, the sides of these soap films would slowly shrink inward to form a minimal surface called a catenoid:
(* runtime: 4 seconds *)
r := Cosh[z];
ParametricPlot3D[{r Cos[theta], r Sin[theta], z, {EdgeForm[], SurfaceColor[Hue[theta/(2Pi)]]}}, {theta, 0, 2Pi}, {z, -2,2}, Axes -> False, Boxed -> False, PlotPoints -> {73, 51}];
