1. distilled water can't conduct electricity? means i teach that the pure(mineral)water is insulated, can be possible. 2. NASA says that they know more about the space compare than earth.what's the truth?

1. Distilled water does conduct electricity. At room temperature, it contains 10-7 M each of H+ and OH-. These charged particles conduct electricity. Of course salty water, with many more ions, conducts better.

2. I don't understand what NASA was claiming well enough to comment.

Follow-Up #1: water conducts electricity

If you had pure water(dielectric) could you still run a current through it? or charge it -+ or does it act as an insulator?

Nico- I've moved your follow-up to a question that pretty much already answers it.
