I thought they were creating this amazing looking wall but instead of showing it they undo-it?
I feel cheated

I would love to have this framed and hanging on wall... cool art.

That's a pretty coAl experiment

Too bad the wood ends burning.

With higher voltage, it's possible to obtain the same effect (in 3D) in a bloc of acrylic: Lichtenberg figure. And that's pretty awesome.

Reminds me too much of 'The Ring' when Samara burns memories and thoughts to walls. The lady also reminds me of Samara.

Slow motion lightning bolt from hell! Fascinating!

i tried it on my wall,,,,, and burned my house

it is amazing to observe the pattern how electricity find its way in a branched manner.

Never ever believe what you see on the internet without research.

#9 your point is ???

Its really cool how turning the voltage down puts it all into reverse it's like going back in time. You would think the wood would be ruined scared permenently but no it's like a miracle a wooden miracle

i would like to hear the sound of that

Those electrons are trying to get to the other side
