Some creative woodworkers have discovered an amazing process for putting unique lightning-like woodburned decorations on wood. It's called lichtenberg and involves running a high-voltage charge through specially treated wood. As the charge burns from one contact to another across the wood, it creates a lightning or tree-shaped burn that branches out across the wood. The technique involves painting the wood with a conductive solution (usually baking soda and water) and applying a high-voltage charge from some kind of transformer. Check out the how-to video below.
