These adjustable metal discharge tongs consist of a plastic insulated handle with two arching metal rods attached at a central pivot point. At the top of each arch, a 0.5″ metal sphere is attached. The arches are adjustable to a max. distance of 11″.
The two adjustable metal arches can be fastened by turning a wingnut and screw. This helps to keep any desired distance between the min. and max. span easily.
These are a must for electrostatic experiments.
