Up close, in the dark: the exact moment an arc forms when approach distance breaks.

36kV energized rod, grounded probe closing in. This is what "electricity doesn't need contact" actually looks like. ⚡

You don't have to touch an energized conductor for electricity to reach you.

This demo at HVL: rod energized to 36kV, grounded probe moves closer. Before contact, the air itself starts to ionize. That sound is the safety margin breaking.

Before any voltage: the boom gets wiped with denatured alcohol,even clean-looking fiberglass can have a film that lets current track over the surface. Then we ramp voltage all the way to a 720kV overvoltage proof, watching leakage current continuously.
