An interesting art/science video shows what happens when 15,000 volts of electricity travel through plywood. I don't want to ruin it for you, but...FRACTALS!
Here's how TwoDayTechnology describes the video on YouTube:“When lightning flashes across the sky, you only get a chance to glimpse its fractal form for a split second. But when you send 15,000 volts coursing through plywood, you get a much better look at how it grows. Melanie Hoff, a student at the Pratt Institute in New York City did just that, and the result is a timelapse where you can see the patterns slowly grow out and smolder, like lightning made from molasses.”
Lightning made from molasses! Love that. It reminds me of similar examples of creating art through science, including these examples of using mold to identify the best transportation routes across Tokyo and from New York to California (Video).
