Glycerine is very hygroscopic, and as soon as it picks up any water, it is
a terrible insulator.
Distilled water has a dielectric constant of 80+ and is a fairly decent
insulator, as long as your pulses are less than a microsecond. It has no
breakdown voltage (i.e. it is a conductor, but a bad one, and the
conductivity is inversely proportional to frequency)
