How to create conductive balls for HV experiments Start with some light balls,ping pong balls or polystyrene balls are ideal. For coverings see below. Method 1 (Aluminium foil) Cover the ball in adhesive aluminium foil. Burnish to a good finish, If using polystyrene balls, be careful not to burnish too hard as the surface is easily deformed.. Method 2 (India Ink) Coat the surface of the ball with India Ink. India ink is slightly conductive and will form a conductive outer shell. coat the ball by holding it between the fingers. When dry coat the bits that were covered by your fingers. Polystyrene balls may need a coating of an acrylic sealant to stop the ink from being absorbed into the polystyrene. Be warned, many products that say they are India ink are actually an acrylic substitute and not conductive at all. Method 3 (Graphite powder) Evenly coat the surface of the ball with glue (be careful not to pick a glue that will react to the plastic surface, PVA works well for both polystyrene and ping pong balls) To get an even finish I rolled the ball against a couple of pieces of acrylic. When the glue starts to […]http://www.extremeelectronics.co.uk/hvexperiments/wp-content/uploads/2013/05/Img20130618_9235-300x249.jpg
