Don’t try this at home! #Repost @physicsfun with @make_repost ・・・ High Voltage Wood Burn: my attempt to make a Lichtenberg fractal by applying a high voltage electrical current across a piece of wood. Inspired by the fractal in my previous post, I realized I had all the equipment needed in my garage including a neon sign high voltage transformer. Here is the burning process using 7500 V at 20 mA. I turned the power off right before the two sides connected to get the fern-like look. The wood is slightly wetted with baking soda dissolved in tap water.❗️WARNING high voltage can kill- do not use a transformer like this unless you are fully trained in electrical high voltage safety. ➡️ Follow the link in my profile for info on how to obtain a fractal like this and other amazing items featured here on @physicsfun #Litchenberg #frozenlightning #fractal #electron #physics #physicstoy #mathtoy #mathstoy #electromagnetism #science #lightning #highvoltage #scienceisawesome #electricity #arc #electricarc #fractalart #beamtree #fractalsculpture https://www.instagram.com/p/BsRc4MkHY88/?utm_source=ig_tumblr_share&igshid=1qb6oyufidl9k
