Fractual wood burning, Napkin Holders and Tissue Boxes

Nice work, Herb. I especially like the cedar ones. It's a shame you're going to stop making them but no project is worth risking your life over. I always used one (right) hand when dealing with high voltages. It's more dangerous to get a shock from one hand through to the other because the path goes closer to your heart. Even the left is worse than the right, when using one hand. I got a shock in college where the TV flyback transformer arced to my finger, the instructor came around sniffing and asked if anyone could smell anything. Smelled like burning hair. I had a hole in my finger about a 1/16th wide by an 1/8th deep, fully cauterized and hard. I hadn't touched a wire or connection, just came too close and it arced. Because an adult male has dry calloused skin, the resistance is quite high but a high enough voltage can overcome that. When you're working with liquids that makes it all the more dangerous by lowering your resistance. It only takes a few milliamps through your heart and it can be fatal.

Herb, if I had heard of this technique decades ago, I would have tried it with a neon transformer. I was cautiously comfortable working with those. The biggest ones were 15,000 volts 60 milliamp although the 30 milliamp ones were more common. They could arc through air about an inch and a half. I made a Jacob's Ladder with one once.
