Melanie Hoff, an art student at Brooklyn's Pratt Institute, connected cables carrying 15,000 volts of electricity to a large sheet of plywood and then filmed the results. Check out her video, and then find out how to make your own Lichtenberg Figure:

April 2013: How It Works
For our annual How It Works issue, we break down everything from the massive Falcon Heavy rocket to a tiny DNA sequencer that connects to a USB port. We also take a look at an ambitious plan for faster-than-light travel and dive into the billion-dollar science of dog food.
Plus the latest Legos, Cadillac's plug-in hybrid, a tractor built for the apocalypse, and more.

No facts, No response...
Eeeek! Is this is what happens when humans get hit by high voltage and lighting a like? OUCH!
Interesting. Does it seem like the electricity wants to travel in one direction (up) on the board, rather than down? Wonder if one could paint using a matallic-based material to help coax the electricity into a given pattern. Very neat video.

In space, no one can hear a tree fall in the forest.
Fractals!
Looks like fun.
FYI to popsci about the title and description... current and the amount of electricity are not measured in volts. You might as well say 15k tablespoons current.

Did you know as you walk across the carpet and shock a friend with static shock, the voltage can be up to millions of volts.
Yes the amps is the more destructive part of power and the most deadliest!
I really wanted to see the end product. It probably would have been a beautiful piece of art.
Big time fail on the wording, "Volt Currents"??? It looks like a river system because water and electricity both follow the path of least resistance. There are a lot of other similarities like parallel circuits and pipes set up in the same way with a fluid in them act the same.

@GMarsack
Like baseballplyrws08 said, electricity follows the path of least resistance. In this case it is the water in the wood. If you watch closely you will see the vapor(steam) rising and billowing upward. This vapor being super heated rises upward and becomes the new path of least resistance.
It might be cool to see what happens if you attach plywood to the ceiling. This would cancel out the "upward" crawling effect.
DO NOT try this with newly treated plywood in a confined space. The great majority of treated lumber is treated with Chromated copper arsenate (CCA). It is a chemical wood preservative containing chromium, copper and arsenic. All of these chemicals are toxic to highly toxic to breath.
