A Lichtenberg figure (IT) is caused by a high voltage discharge you can find them as scars on lightning strike victims and also from arcing where high voltage is present. Last week we talked about microwave ovens that was because this week you will need two of them to salvage the transformers. With two transformers and a lot of caution so you don’t kill yourself you can make your own Lichtenberg fractals on wood. Dangerous high voltage involved that can easily kill you!!
