Electrostatic Plume Set

This set of two electrostatic plumes can be used for a variety of electrostatic experiments.  Each electrostatic plume consists of a metal rod mounted on an insulated plastic stand that carries a round metal plate at its top and a fringe of 40 colored nylon cords. When the plate is touched with an electrostatically charged rod, the cords become charged and spread out into a wide cone by mutual repulsion. Each electrostatic plume is well insulated and will hold its charge for up to 30 minutes in dry air.
