Kynar wire corona ozone experiment.

Having discovered that Kynar insulation is quite ozone resistant, I decided to do a test by twisting two short lengths of Kynar insulated wire-wrap wire together in a tight helix and connecting them across the output of a high frequency, high voltage cold cathode driver. The result was a purple corona discharge along the entire length of the twisted area, and a strong smell of ozone. It lasted for several minutes, but the insulation succumbed to the high voltage and flashed over. Shame, as it would have been about the easiest way to make a corona discharge that I'd come across.
