15,000 Volts Into Wood

What happens when you connect cables carrying 15,000 volts of electricity to a large plank of wood? Melanie Hoff, a student at Pratt Institute, found out.

    That’s really cool how reversing the flow caused all the burn marks to disappear.

    That was pine, put your beer goggles on and try it with Ash or Hickory…..

      My ‘semi’ educated guess is that this is a product called “Luan’. It is a veneer of Philippine mahogany, just over 1/8 thick and has 3 plys, usually used for cabinet backing. No solid ‘plank’ of anything exists of that size anymore.
      My guess is that adhesives used in the plywoods construction, and internal moisture have something to do with the electrical conductivity we see here. (they may have hosed down the back side)
      Wood, when dry, is actually an excellent insulator, and does not conduct electricity very well at all. (power poles are made of wood)
      15,000 volts is about what is used as an ignitor in a standard oil burning home heating system.

      Regardless…. It makes great artwork, And I would love to cover a wall or two with it!

      LOL @ Qoumidan…..

    I bet that smelled wonderful. I worry (maybe hope?) that some copycat will try this at home and not realize you should turn of the electricity while handling the wires.
