  We investigate the effect of electrical charge on the normal mode frequencies
of electrically-charged diamagnetically levitated water droplets with radii
4.5-7.5 mm using diamagnetic levitation. This technique allows us to levitate
almost spherical droplets and therefore to directly compare the measured
vibrational frequencies of the first seven modes of the charged droplet with
theoretical values calculated by Lord Rayleigh, for which we find good
agreement.
