What causes lightning? The answer keeps getting more interesting (quantamagazine.org)
nomilk 1 hours ago [-]
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.

https://www.youtube.com/watch?v=5BJIiX9_c_M

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

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

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

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.
