    Hello, this is really cool! I am testing my thermochromic paint on paper with copper tape, conductive paint, and graphite paste with unsuccessful results. May I know what conductive material you are using in the ‘A Perfect Circle’ Video? Is is conductive pain?

    I meant, is it conductive paint 😀
