3DDouble-discharge Lichtenberg figure.
This lichtenberg figure was made by Bert Hickman and his partners at a facility in Ohio. I came along to watch and write about the process for an article that will be in my Popular Science magazine column.
Like the one above, this figure was charged up from both sides, but unlike that one, it was discharged after the first side was charged, then it was charged again from the other side. This caused there to be many, many individual discharges during the second charging phase, resulting in a sort of forest-of-lightning-strikes effect (which you can only see properly in the rotatable 3D version).
