Pieces of adhesive aluminium foil are glued to the inside of the jar first. This way its easier to see which bits you have missed the strips should not come more than 3\/4 of the way up the jar for the highest voltage capacity If you can&#8217;t get you hand in to the jar to stick the pieces down use the handle of a screwdriver\u00a0 to smooth out the pieces. The foil does not need to be absolutely smooth, but there must be no gaps. Corona will form on any edge and eat away at the foil. Go right around the jam jar until the whole of the inside is covered. to the 3\/4 height. Strips of 20-25mm work best. Larger strips become difficult to handle. \u00a0For the bottom of the jar use 25mm square pieces. Stick them on to the end of your screwdriver to position them. You may need to use more than one screwdriver to get them to stick where you want. Cut a circle of Acrylic bigger then the lid of the jam jar, and cut a circle of copper or brass to fortify the bottom.
