Even ultrapure water conducts electricity. It says right here [1] that its resistivity is 1.82×10^9 Ohm * m. This is a pet peeve of mine. We get told of conductors and insulators in school, but it doesn't work like that. Pretty much everything except a perfect vacuum conducts electricity. It's just that some materials conduct electricity so poorly that it can be rounded off to 0 in most circumstances, but there can still be measurable current flow.
