Pure water is an insulator until it breaks down. the minimum breakdown voltage of distilled water under negative impulse at 2mm inter electrode gap spacing is 27kV with 14us breakdown time. The breakdown strength of distilled water is higher under positive impulse than negative impulse at same electrode gap spacing. If the breakdown voltage for air were 10kV/cm, then that would imply pure water is a better insulator than air. Don't bet your life on it though! https://digitalxplore.org/up_proc/pdf/149-143254025539-45.pdf https://digitalxplore.org/up_proc/pdf/149-143254025539-45.pd...
