These electrostatic discharge tongs measure 20cm in length and feature two jointed metal rods terminating in small, plated brass spheres. The spheres are adjustable to control discharge distance and intensity. An insulated ebonite handle prevents accidental electrical shock. The tongs are designed to safely discharge static electricity accumulated by electrostatic generators such as Wimshurst and Van de Graaff machines. Suitable for physics classroom demonstrations and controlled electrostatic discharge experiments.
