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

You'd probably need a very large balloon to overcome the weight of the string

Maybe just salt water and skip the filings?

Tl;dr lightings may be caused by electrons/positrons from outer space hitting a cloud and initiating an "avalanche" of electrons.

Cosmic rays are mostly protons, not electrons or positrons. You're mixing up to separate theories in the article.

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.
