  That 7 second video of a small rocket shot into a cloud to induce a lightning strike (about half way down the article) is incredible.

  Any ideas why the lightning strike appears mostly green (and momentarily purple and orange)?

    I always wanted to replicate this with a helium balloon and a long, wet string coated with copper filings.

    I'm imagining it's something related to the copper wire.

  just in case you missed it, all matter carrys a charge, and all space(and matter) has energy radiating through it, making the universe an energy gradient.

  sometimes you can see it happening.
