When small bits of aluminum foil, pith, or vermiculite are
placed in the cylinder and the upper plate is brought near an
operating generator, the particles will bounce rapidly. They
are first attracted to the upper plate but, after touching, are
violently repelled downward. The precipitation of smoke may
also be shown.
Available in small or large sizes. Small unit is 29 cm
tall with a 7.5 cm diameter cylinder. Large unit is 37 cm
tall with a 15 cm diameter cylinder.
