Vertical sinusoidal forcing of glycerin-water establishes periodic surface waves. With increased forcing, the solution reaches a quasi-periodic state of various wave heights. Under even higher amplitude, jets can be produced. These jets are examples of singularities, defined by a diverging velocity gradient. Difficulties in modeling the surface arise from nonlinear boundary condition equations.
