What are some substances with low breakdown voltages?

  1. Apr 9, 2012 #1
    I was studying RC circuits recently and I'm interested in this:

    It would be awesome if I can recreate a circuit like that. I know how to make a capacitor myself, but I don't want to buy a neon lamp. I'm wondering if there are any substances with low breakdown voltages? The lowest breakdown voltage I've seen in my textbook is several megavolts, and I can't reproduce that at home (it would be dangerous too). I've heard that salt water is a good conductor and distilled water is ideally an insulator. Maybe I can vary the salt concentration to create something with a low breakdown voltage?

    Thanks in advance!
